The current paper will put emphasis on the integration of the emerging energy saving technologies and solutions on existing merchant vessels. It is our belief that the introduction of energy saving technologies can provide significant performance improvements contributing to the increase of the vessel energy efficiency. This integration needs of course to be tuned to each vessel type, size and operations. It requires a significant effort to maximize the efficiency improvement at the lowest initial cost. The purpose of the present study is to analyse these integration issues and provide useful guidelines to the marine industry.

This presentation will review the various options which operators can adopt in the drive to decarbonize. Focusing on the pathways specifically for short sea cargo vessels, the presentation will provide a valuable perspective on how to assess alternative fuel and machinery options as well as scenarios in order to select optimum solutions.

While it is prosaic to say that no ‘silver bullet’ exists for marine decarbonization, multiple solutions are emerging. IDTechEx sees green hydrogen or ammonia powered fuel cells (FC) as a promising pathway to zero-emissions in hard-to-abate sectors. Hydrogen PEMFCs are the most technologically mature and the focus of suppliers, while solid-oxide FCs are nascent but solve many of PEMFC’s pain points with fuel-flexibility and efficiencies of >80%. This presentation covers FC technologies, market adoption, and a market outlook using primary research from the IDTechEx report ‘Fuel Cell Boats & Ships: PEMFC, SOFC, Hydrogen, Ammonia, LNG 2023 - 2033’.

Future prices of alternative green fuels may be a multiple of fossil fuel prices whilst their availability will continue to be in low volumes for some time. Energy Saving Technologies (EST) such as wind propulsion and hull air lubrication are required now to address the challenge of the IMO’s CII targets. Demand for ESTs will persist to allow range to be extended with the low energy density fuels and to reduce fuel demand to offset their high prices. In this presentation the benefits achieved when different ESTs are combined on a dry bulker are presented.

This presentation will describe how to use techno economic analysis of the various solutions in actual applications. The comparison is then used to help choose the optimal solution for the customer. The presentation uses an example of how the tools created for this purpose are used to evaluate and select a decarbonization path for a customer looking at various fuels, ICE engines, Fuel cells, and hybrid solutions.

Global regulations and emissions legislation puts increasing pressure on shipping to decarbonise, driving the sector towards flexible, electrified, and hybridised solutions, combined with alternative fuels. Embracing hybrid and electric concepts that lay the groundwork for low and net-zero carbon operations is vital, particularly with rapidly ageing fleets. Wärtsilä, has well-established hybrid and electric concepts. Its modular, hybrid propulsion system can be tailored to specific needs and vessel operating conditions with full integration at the shipyard. Its modern engine portfolio includes a suite of new fuel-flexible options that drive decarbonisation and fit the core power demand of the vessel operating profile

This presentation will look at the energy efficiency steps ship operators are taking towards a greener future for the shipping industry, including cruise and ferries, grey ships, commercial vessels and ports and how these are now impacting ships PQ and THD levels! This presentation will identify some of the concerns that operators need to be aware of when implementing decarbonisation and energy reduction solutions using VFD’s, LED’s etc, and how they may negatively impact class rules for limits of Total Harmonic Distortion (THD) and associated damage to the ships electrical systems.

The decarbonization of the global ship traffic is one of the industry’s greatest challenges for the next decades and will likely only be achieved with the introduction of synthetic fuels. Until now, however, not one single best technology solution emerged to ideally fit this task. Instead, many different energy carriers including hydrogen, ammonia, methanol, methane, and synthetic diesel are subject of discussion for usage in either internal combustion engines or fuel cells. In order to drive this ongoing discussion, we prepared a case study for the year 2030 with all eligible combinations of power technologies and fuels.

This presentation will discuss the integration of various renewable forms of energy storage (batteries, hydrogen, ammonia, methanol and others) and power generation systems (batteries, fuel cells and internal combustion engines). It will discuss the use of risk-based design to obtain equivalent levels of safety based on functional rules where prescriptive rules are too conservative or missing.

Fully integrated hydrogen fuel cell systems are revolutionizing several sectors. These systems contain all the components, subsystems, and control software necessary to efficiently convert hydrogen into high-voltage electricity, without any emissions other than pure water. In this presentation, several successful maritime applications of these systems will be discussed ranging from the 9m-long water taxi that was located in front of the expo entrance last year to the 67m-long training vessel "Ab Initio".

The journey towards decarbonisation is challenging for the maritime industry. Several different energy carriers and fuels are considered and evaluated. Battery is a wise choice in many applications but has its limitations. Therefore, both combustion engines and fuel cells are alternatives. These must be piloted with different fuels for further evaluation, learning and development. SEAM will, in this presentation, share experience from several maritime projects with fuel cell electrification and integration. The experience stretches from initial concept design and approval processes, until several months of duty with vessel operation in normal sailing conditions. Projects include both liquid and compressed hydrogen, as well as ammonia as hydrogen storage.

This presentation will review the challenges of battery and alternative fuel usage and offer some perspective on how the various challenges can be addressed in the course of moving forward on decarbonization.

A deep dive into the challenges of system integration onboard vessels in the offshore wind segment and how to achieve optimal energy of onboard power systems. We look at today´s technology and the role system integrators will have in preparing vessels for the green transition and facilitating for seamless integration with future energy sources.

A large challenge when developing future hydrogen and EV propulsion systems lies in the ‘invisible’ specialism of integration. Matching, optimising and ensuring seamless control and communication of sub-systems in an efficient and safe manner is critical. The engineering effort to do this is and get to production isn't insignificant. The result? For many low-mid volume manufacturers of commercial vehicles and industrial equipment, the development cost of adopting hydrogen isn’t feasible, slowing the market and stunting end-user demand. This presentation will review the challenge and look at potential solutions to the invisible problem of integration, enabling a new era of possibilities.

Hybrid technology has demonstrated fuel consumption reduction potential in marine applications. Simultaneously, the marine industry is under pressure to rapidly decarbonize. This has led to the research and development of low life-cycle carbon fuels for combustion such as ammonia and methanol. However, there are significant barriers for these fuels to span full engine operation required of conventional diesel or natural gas marine engines. Hybridization is an enabling technology for these fuels by supplementing operation in key areas. This presentation highlights the technology of MAHLE Powertrain’s high power / low voltage hybrid system and its synergies with combustion of low life-cycle carbon marine fuels.

Over the next decade the marine industry will see a significant increase in low-carbon fuels like Hydrogen, Methanol, Ammonia and others. How are these going to impact the marine industry and the electric systems onboard ships? Electrical Power Systems and Safety & Control Systems will become more complex and critical to ensuring reliability to maximize vessel operation, but also to optimize energy sources available onboard. To validate operational forecasts using data analytics, monitoring and optimizing the power plant will be of significant importance to reduce OPEX and record vessel emissions.

The Wind Hunter project is the ultimate zero-emission driving project, which combines wind propulsion sailing technology and wind energy converted to generate a stable supply of hydrogen. The Wind Hunter project applies this technology and combines hydrogen carriers and fuel cells with hydrogen generated by electrolyzer. The power is generated by power generation turbine. This combination of sail and hydrogen technology will enable vessels to sail on schedule even in periods of low wind.

CalMac Ferries have been operating three hybrid diesel / electric / battery ferries for eight years resulting in 23 years of operational experience. These ferries operate across Scottish Lochs and plug in and charge the batteries overnight which provides approximately 20% of the propulsive power during the timetable operations. This presentation will cover lessons learnt from operating hybrid ferries, the positives and challenges faced. It will review the commercial aspects and will also look to the future to discuss what may be coming next and how this experience is being used to prepare for all electric Scottish ferries.

Battery powered electric and hybrid marine vessels are starting to become commonplace as the maritime industry works to cut its emissions and improve the industry’s impact on climate change. But the path to greener vessels is not without its own challenges. New technologies mean rethinking every aspect of a vessel – not just its fuel sources. Learn about the fascinating journey from the companies involved in building and operating the world’s largest hybrid ferries – Brittany Ferries, Stena RoRo, Wärtsilä and Leclanché.

This presentation provides a case-study which demonstrates the various aspects of introducing automooring which operators need to consider. The study includes a review of the performance of the system itself, the preparations onboard the vessel taking into consideration both retrofit and new build projects. In addition, it considers the necessary shore side civil works. Importantly for operators considering such a project, the presentation outlines the required approvals, permits, timeline, work procedures and the consequent impact on operational practices, and a review of costs and emissions. This presentation is an absolute must for both vessel and port operators considering automooring especially for ferry traffic.

Ambitious net carbon zero goals demand equally ambitious solutions – and the Short Straits Green Corridor project will determine viable energy pathways for both marine vessels and landside operations. We’ll assess their direct and indirect environmental impact and identify where regulation and new policy initiatives can contribute to a successful outcome. By August we will have created a green corridor business case together with a three-tier route map to attract private sector investment, up-scale the number of zero-emission vessels, ramp up landside infrastructure and create a blueprint for green corridors across the world

This presentation will provide a thoroughgoing exploration of the KOTUG E-Pusher type M and the benefits for owners of the approach to modularity and scalability it provides and the usage of a containerized energy storage solution for the electrical propulsion. The KOTUG E-Pusher is a series of modular and scalable electrically powered pusher boats for the transportation of a wide range of cargo flows. Combining assembly construction with the globally patented design of the zero-emission E-Pusher is an entirely new approach in shipbuilding. The design of the E-Pusher offers the unique ability to switch energy sources, varying from fossil, hydrogen, and fully electric energy. The series consists of four models to cover all the inland waterways: the E-Pusher CityBarge (for inner cities) and the E-Pusher S, M and L for larger waterways. Focusing in this presentation on the E-Pusher Type M, equipped with the EST-Floattech Octopus Series containerized solution.

This extended presentation discusses the integration aspect of new alternative technologies to either existing ships or how it should be considered in a new build where the expected lifetime of the ship is 20-30 years and where it may be necessary to do a midlife upgrade to next generation of alternative technologies The participants are Foreship, a highly respected, ship design and engineering company which has developed an unrivalled breadth of services since its formation in 2002 and their customer Carnival Maritime who will bring the perspective and strategy of a ship owner. Following the presentation of the perspectives the presenters will open the floor to questions and discussion.

Work Package 7 (WP7) of the EU ShipFC project aims to turn the technical and economic knowledge developed through the project into a broader analysis of the positioning of NH3/SOFC in the maritime sector and compare it with alternative fuels. To achieve this several actions are necessary such as: Establishing a reference database of socio-economic parameters characterising the relevant maritime sub sectors for the introduction of SOFC/NH3 power supply. Modelling of NH3/SOFC power systems on board ships. Modelling of NH3 supply chains for maritime applications (Using TedHy tool from Persee). Creating a ShipFC tool to best provide decision support to ship owners when considering investing in Fuel cells. Running end to end cases analysis with partner vessels using both the ShipFC tool (for on board the vessel analysis) and the upgraded version of TedHy (for the NH3 supply chain). The presentation will describe the actions already taken, the actual state of the project and the steps that must be taken in the future to achieve the desired objectives.

As the next step towards creating a Short Straits Green Corridor, we’re developing a viable fast connection, high energy supply for cold-ironing and battery recharging for high frequency ferry crossings across the Short Straits. Specifically, we’ll upgrade a trial berth to deliver: one fast berth to ferry electrical connection for charging and cold ironing to one operational hybrid ferry with shore connection upgrade and onboard power management supported by a direct electrical connection from grid to berth. Upscaling beyond this practical trial will be simulated by a digital twin illustrating infrastructure upgrades to grid /local energy storage, power management and connections across multiple berths.

This presentation will provide a brief overview of the strategy of the Amsterdam Port Authority concerning the development of clean shipping in the Amsterdam Port. It will answer, among other questions: What is the role of a pro-active port authority, which clean fuels are best for maritime use, how to implement on shore power supply, and the role of smart shipping. The presentation will provide insight concerning strategy but also cover relevant concrete actions and pilot case studies.

The Port of San Diego is focused on reducing emissions by implementing its Maritime Clean Air Strategy (2021). The terminals are adjacent to an urban area where the residents have many more than average health issues affected by air quality. The port is, therefore, reducing greenhouse gases as well as criteria pollutants (i.e. nitrogen oxides and diesel particulate matter, etc.). In this presentation Thomas Maclean who is Program Director, Energy and Policy at the Port of San Diego will discuss the current efforts which include: Vessel speed reduction as ships approach. Electric assist tugs in the bay. Shore power for ships at berth. Electric cargo handling equipment -- cranes, yard tractors, etc. Zero emission trucks for on road.

A full electric ferry route depends on deep technical knowledge. From the complexity of the onshore grid to the transfer of power and energy from shore to the vessel. It’s important to understand how to handle the energy received onboard, from the plug, via the battery system and to the propulsion system and other onboard systems. Communication between the vessel and the charging station to create safe, reliable operation is all about choosing a system integrator which knows all the key elements, from grid to propeller. This presentation will highlight the most essential elements a system integrator needs to consider in zero emission ferry operations.

This paper will present the main characteristics of recent and on-going projects of PLUG shore power as well as review the new developments we foresee. In particular to support future full electric large RoPax projects which are coming up in the constant need to reduce shipping emissions.

The present focus of the shipping industry is to enhance vessel efficiency with reduced environmental footprint. Electric Hybrid/ Pure Electric propulsion is still in the development stage. Safety and fast charging of batteries are still a big hurdle to overcome. In this presentation, future options for marine fuels like hydrogen, gas to liquids, ethanol, biogas along with better current/charging capacity of Li-Ion batteries will be discussed

This presentation will describe a megawatt charging system (MCS) which features either a manual or an automated connection to the vessel inlet. The charging system provides industry-leading charging speeds and consists of a high-power electronic module with a cooling device, an MCS connector with a liquid cooled cable and an MCS inlet as a mating device located on the vessel. Active cooling enables the system to provide between 1MW and 4.5MW of charging power (up to 1500VDC and 3000A). The MCS system, developed by Cavotec, also provides crucial data such as voltage, amperage and system temperature via user dashboards.

For all their environmental benefits, offshore windfarms aren't an end-to-end 'green' solution. Essential maintenance on these remote assets requires vessels to travel to the turbines - vessels which often by necessity run on harmful fossil fuels. This presentation will outline how PwrSwäp, the first of its kind, pay-as-you-go energy-subscription service is used to electrify this fleet of workboats, adapting wind turbines at remote offshore locations to become charging stations for the interchangeable battery ePods. This scheme not only extends the range of fleets servicing the farms but can also be used by vessels in transit to optimize the farms' "green value". Brent Perry, CEO of Shift Clean Energy will speak about the benefits of electrifying microeconomies and vessels holistically, and the role of PwrSwäp as a viable, commercial solution.

The benefits of electrification are well known but there are still a lot of nuances and challenges on the way to sustainable marine transportation. How is it possible to have higher productivity and shorter ROI? When more ports have automated charging infrastructure it is natural that more standardization will follow. This will improve acceptance, interoperability, needed investment and total project lead time. It cannot compromise safety and productivity, therefore quality, reliability and automation are top features for chargers. Considering all ports with their different infrastructure and environmental factors, it is challenging. This presentation will describe how it is possible.

Following the installation of UK's first marine charging network in Plymouth, Aqua superpower is leading a consortium to explore the development of a UK demonstrator of bi-directional vessel charging. The Virtual Bunkering for Electric Vessels (VBEV) project will focus on emergent bi-directional charging technology developed, demonstrated and in early release for road vehicles. This game-changing technology has already demonstrated that it can effectively enable electric vehicle drivers to reduce their energy costs and cut carbon by accessing greater levels of renewable technology at off-peak periods and discharge energy when needed.

This presentation will cover a collaborative concept that has been developed using Verlume’s subsea battery storage system and Oasis Marine’s offshore charging solution to establish a novel network of intelligent in-field charging infrastructure powered by renewable energy at offshore wind farm sites. As one of the major barriers to full electrification of offshore maintenance vessels is the range of their battery technology, the at-sea charging will accelerate the adoption of hybrid and fully electric vessels by providing a means of maximizing operating efficiency and range, as well as the value to both the vessel and offshore wind farm operator.

This presentation will start with a review of shore power market situation in Europe. This will include technology trends as well as the most common challenges for ports during the preliminary phase and procurement. The presentation will be based on cases from different ports in Europe where cable management system solutions were sought from ShoreLink. In addition to that, recommendations for related stakeholders will be provided.

The number of existing vessels is vast, and it is not that viable to replace them all with new-builds. Shore charging infrastructure for larger vessels requires substantial infrastructure. Charging technologies for leisure boats and small craft, whilst not requiring that sort of infrastructure, is quite limited without it. However, some of the more useful electrification projects are for vessels serving passenger and vehicle traffic often at relatively small scale and in inhabited areas, city centers, river crossings and narrow straits. Exactly the places where the need for clean air is highest. This presentation will describe a solution especially suitable and just right for the large number of projects in this in-between category.

This presentation brings the perspective from Class. It considers the regulatory framework, provides feedback from projects on regulatory approval, and offers a technology overview.

Shipbuilders face a high bar in the shift to greener technologies – reduce carbon emissions by at least 50 percent by 2050. Hydrogen-on-demand offers a solution. This presentation will describe a patented system which eliminates the complexities of compressed cryogenic liquid hydrogen by tapping into safe, stable methanol as a feed source. Existing diesel tanks instead store liquid methanol at ambient conditions, and hydrogen systems drop into existing shipboard infrastructures with minimal retrofit while meeting decarbonization mandates.

While batteries, variable speed drives, and motors of hybrid propulsion systems are chosen carefully, it appears that the rest of the driveline is chosen based on the lowest investment cost. However, when savings are made in the wrong place, there is a significant impact on the reliability and performance of such systems. As a result, issues concerning the mechanical drivetrain, such as component reliability, system stability and condition monitoring often go unaddressed. By tackling these challenges early in the design phase, false economies can be avoided, and the hybrid powertrain can operate with the lowest total cost of ownership.

Hybrid Combined Cycle is an innovative power and propulsion plant concept utilizing 13MW class gas turbines in combination with small reciprocating engines, steam turbines and battery energy storage. This technology combination allows optimized energy efficiency across a wide operating range, minimizing fuel consumption and reducing overall CO2 emissions. With LNG as the primary fuel, this gas turbine-based system offers low NOx emissions and low methane slip too. The presentation will also cover ongoing development work to enable the gas turbine to operate on hydrogen and methanol, while retaining LNG capability, for maximum fuel flexibility with minimal performance impact.

Exploring energy efficiencies of the production value chain and marine design considerations by lower carbon intensity fuel-type, including electrification, for marine segments. This presentation will provide an introduction to a short carbon cycle for methanol as a hydrogen carrier and marine fuel. It will showcase how an energy source mix of lower carbon intensity fuels and renewable shoreside power correlates to propulsion arrangements. The marine energy transition is supported by three (3) pillars: Energy Substitution, Energy Displacement and Energy Saving. Caterpillar has been working on the energy transition for a long time and can help define environmental goals and develop services and products that meet a variety of industry needs.

The fully electric e-ferry Ellen launched in 2019 operates from the island of Aeroe in southern Denmark. It sails a record-breaking distance between charges: 22 nautical miles, up to seven times a day. Besides discussing the e-ferry’s systems and achievements, the presentation will cover Ellen’s continued operational experience, including the battery status after four years in operation, including operations through periods of extreme cold. The presentation will provide key numbers and figures and give real-world feedback on e-ferry operations over longer routes and during cold weather.

This presentation will review the business and strategic considerations for tug operators, owners, and regulators; whether independent operators, port authorities or increasingly shipping lines operating proprietary tugs. Tugboats are too small to come under IMO GHG regulation, but they do operate in complex and sensitive areas where environmental considerations are focused on local air quality, but also individual decarbonization targets of different stakeholders. This in turn means that the strategic drivers are somewhat different than for larger shipping and more varied. The analysis will include harbor and escort tugs and detail the best options for energy source, machinery type, propulsion, efficiency and reliability. The conclusion will offer insights on costs and benefits looking at capex, opex and lifetime costs of the options available.

This extended presentation brings together the partners of M/V Hydrogen One. It highlights the ambitions of the project, its development work and lessons to date. The presentation asks whether a single vessel has the potential to radically change how an industry operates. M/V Hydrogen One is on track to be the world’s first methanol-run hydrogen fuel cell working towboat. A vessel which could unlock a sustainable maritime industry and the decarbonization of inland waterways and larger ocean-going vessels. Austin Sperry, President, Maritime Partners, will highlight the ambitions for the project, including the incorporation of Hydrogen One into its own fleet of vessels as well as perspectives on the market dynamics for investing in new low emissions vessels. Robert Schluter, co-Founder and Managing Director of e1 Marine, will share how its technology can create fuel cell-grade hydrogen from methanol and water, safely and cost effectively onboard vessels and what the Hydrogen One project could signal for the wider decarbonization of the maritime industry. Dave Lee, VP of Sales - Global Workboat Responsible Marine Systems, ABB Marine & Ports, provides insight into the case for electric propulsion versus diesel, factors to consider including emissions, efficiency and range alongside the development of new standards for onboard use and integration of new power sources. Brian Reid, Chief Sales Officer at Rix Industries can offer insight regarding applying fuel cell technology to the vessel, including e1 marine's solution as well as switch gears and batteries.

MS Medstraum is the world’s first zero-emission all-electric fast ferry. It won the award of "Ship of the Year 2022" and it's a vessel whose many technical innovations have great transfer value to other ferries. Operating now all day, every day on a multi-stop commuter route it can carry 147 passengers at a typical cruising speed of 23 knots. Though the route is fixed, there are 12 potential stops along the way depending on whether any passengers are waiting at that stop. The actual route therefore varies, which is somewhat novel for a ferry. The vessel comes out of the TrAM (Transport: Advanced and Modular) project, funded by the European Union’s Horizon2020 Research and Innovation program and facilitated by the Norwegian cluster organisation Maritime Clean Tech. The aim was to develop a zero-emission fast ferry concept through advanced modular production. It is expected that modular manufacturing methods will reduce production costs by 25% and engineering costs by 70%. In this presentation the builder Fjellstrand Verft.will use information from the designer Kolumbus supplied by the operator Norled to explain the benefits for ferry operators, and vessel owners more widely, of adopting a modular approach.

This extended presentation is aimed at helping vessel owners and operators assess whether vessels powered by ammonia with fuel cells offer a feasible immediate solution to their need to decarbonise. It will feature the experts involved in the development of the first vessel to be powered by ammonia in combination with fuel cells. The presentation Includes joint Q&A where you can ask questions of all parties.

This presentation will provide an update on Beluga 24. Together with some of the world’s best experts including BAE Systems , Green City Ferries has developed a 150-passenger ferry making 30kts of energy from either batteries or hydrogen. In the high-speed segment, it is all about energy efficiency because batteries, as well as fuel-cell installations, weigh a lot more than diesel drivelines. This speech will outline the challenges and choices made. The presentation will cover technical, economic and political challenges; the impact of efficiency; the performance of Beluga 24; the choices made in the design phase. The presentation will include input from one of the key stakeholders in the project, BAE Systems.

This presentation will provide vessel owners currently considering their decarbonization pathway, with a comprehensive understanding of the business case for wind assisted hybrid propulsion. This focus reflects the remarkable uptick in interest by vessel owners in this strategic option. Covering the specifics of types and operational profiles along with the dynamic routing technology, a real-world analysis will be offered in particular comparing fuel savings and efficiency improvements available (EEX/CII).

This deep dive presentation is aimed directly at vessel owners and operators considering a retrofit or new build utilizing battery ESS. It aims to help them understand the real costs of over specifying battery applications. C-Rate is an overused and mostly misunderstood phrase in the battery industry. Vessel owners often ask for a 2 C or 3 C battery without really understanding the true costs associated with a high C rate system. This presentation will give a detailed definition of C-rate and will go into the benefits, costs and risks associated with high c-rate and low c-rate batteries and their support systems.

This presentation will describe a powerful tool for ship builders and operators which increases their insight into system performance in order to reduce operating costs and environmental footprint. WinGD Integrated Digital Expert (WiDE) uses advanced data acquisition, analysis and modelling to compare energy systems in-service operation with their ideal reference performance for real-time conditions, identifying anomalies before they raise alarms and alerting crew to potential issues. The presentation will demonstrate how owners and operators of hybrid vessels can minimise costs and risks by using WIDE alongside the WinGD X-EL virtual integration system (described elsewhere in the conference).

In this presentation two advanced methods of power analysis will be explained, both significantly shortening the test time for electric drives. The first one is a dynamic power measurement method (based on switching frequency, patent pending). This allows machine mapping and WLTP testing in parallel, rather than in series. The second one is cycle recording based power analysis using advanced cycle detection and this method allows dynamically reduced setpoint test time with increasing rpm and thus shortens the total test time of an electric motor.

This presentation highlights the multi-objective optimization of a fuel-cell powered in-harbour tugboat propulsion under selected duty cycle and weather conditions. The dynamic and multi-physics system simulation model integrates a thermodynamic / electrical fuel cell (balance of plant) and an electro-chemical energy storage model offering realistic component behavior. The optimal controls solution utilizes an online model based ECMS Controller capturing the dynamics of the system and its constraints. The proposed modelling approach exploits the energy saving potential of the propulsion and power supply system design, grants deep insights into component health aspects and thus offers a reliable and efficient development workflow.

This presentation will take the audience through the modelling process and share lessons derived from a comparative emissions model to analyze greenhouse gas emissions, CO2, and regulated emissions. The comparative model has been developed by e1 Marine and its accuracy has been independently verified. e1 Marine uses methanol steam-reforming to generate hydrogen for fuel cells used in maritime vessels to compete with marine diesel engines. The model and the analysis are used to explain how this can apply to real world operations for reducing emissions. In this case the model was applied as a case study to the hypothetical operations of a 2000 HP pusher boat, Hydrogen One, operating on inland waterways around the US Gulf Coast. The results indicate that methanol-reforming with green methanol produces significantly fewer greenhouse gases and regulated emissions than diesel engines. Even when using grey methanol, the model still shows improvements in greenhouse gas, CO2, and regulated emissions.

This presentation gives an insight into the optimization quality and the benefits that simulation enables. The complexity of the AC part in ship grids has often decreased, but significantly, on the DC side, it has increased. For example, the dynamics of a DC system are much higher, and simply assuming that the system will work properly is too risky. For this reason, it is necessary to carry out simulations that are able to investigate the system dynamics as realistically as possible. The method of choice is a Hardware in the Loop (HiL) simulation which integrates the real control hardware.

Class societies have a role assuring overall ship safety, considering all relevant risk factors to supervise design, construction, and maintenance. The current trends to decarbonize shipping, novel electrical and hybrid propulsion systems, automation, and the corresponding increase in systems complexity, creates demand to assure that the ship itself, its equipment and operation will not lead to any unwanted scenario. Recently published data by EMSA present some unwanted trends needing analysis to minimize the already known ship related risks with power generation, propulsion and navigation that are also present when we introduce alternative technical solutions for multimodal waterborne transport safety.

This presentation will describe a modular and flexible approach to hybrid-electric solutions. Jan Willem Vissers, Director of Marine Commercial Sales, will share real-life test cases of Volvo Penta's fully integrated, hybrid-electric solutions – from helm to the propellers, including tests of pay by the hour business models.

An appropriately controlled hybrid energy system as an integral part of the ship’s energy system is emerging as one of the most cost-effective solutions for deep-sea vessels to meet future environmental targets, combining the high efficiency of low-speed two-stroke engines with optimally sized electric drives, machines, and energy storage units. This presentation will describe WinGD’s proprietary energy management system X-EL which ensures that the vessel has the right power delivered in the most fuel-efficient way at all times. It combines simulation of the energy system with real-time monitoring to identify the most suitable mode of operation for current conditions as well as improving reliability and load response across the integrated power system. The launch of X-EL follows WinGD’s first contract to deliver hybrid system integration and energy management, for four LNG-fueled pure car and truck carriers due to enter service in 2023. The vessels will be powered by X-DF2.1 dual-fuel engines as part of a battery-hybrid system developed by WinGD.

Electrification and hybridization of vessels is essential to help reach the goal of a greener and low-emissions future for the maritime industry. Along with these technologies, data-driven intelligence, control and optimization tools can yield further reductions in maritime GHG emissions and help implement the path to decarbonization. This presentation will cover technologies, system architectures and optimization solutions available from GE that can be adopted to help vessel owners operate more efficiently today, whether at sea or in port. Based on GE’s expertise across energy, renewables and maritime domains, they will outline how electric ship and digital technologies are also important enablers to integrating and managing a transition to cleaner energy sources into vessels and ports’ power networks. They will conclude by considering the practical system- and operational-readiness level steps that, working collaboratively, will support adoption of new technologies in the sector.

Siemens Energy provides electricity with its wind and solar generators. In order to store this electrical energy, it is converted, by electrolyzers, into chemical energy, which can be bunkered, transported or converted into other fuels. This presentation will describe the solutions offered by Siemens Energy and its partners for the re-electrification and distribution of that electrical energy for maritime applications.

As the new IMO regulations force vessels to reduce their carbon footprint, DC distribution offers a viable option to reach these targets. This creates a shift in technology from AC systems toward DC distribution. The presentation gives an overview of the DC distribution benefits. It discusses the different protection methods needed in DC distribution compared to AC. It gives an understanding of why game-changing protection technology is needed and provides a solution for protective devices that cover various failure scenarios supported with a case study.

The structure of a Marine DC grid enables control and protection in a different way, as usually employed in AC grids. Power electronic converters are used for both control and protection. The structure of a DC grid is also determined by the type of power electronic converters being centralized or decentralized. Power congestion management greatly improves the fault tolerance of a DC grid. Although power electronics introduce extra losses, the DC grid can be used more efficient than the AC grid.

The Marine Industry will require Megawatt charging & beyond. To be able to handle those power levels harbours will require encrypted communication protocols that allow for Smart charging, V2G capabilities, Automated charging, Wireless charging, seamless payments between CPO in different locations. This presentation will provide a thorough overview of the MCS.

Damen already has experience with developing and realizing charging systems for fully electric vessels. These shore-side charging solutions have been developed dedicated for each specific ship type. For the next step in the electrification of shipping, “charging as a service” has to be available in locations where these ships are operating. This requires standardized charging solutions for interoperability. The (Megawatt) charging standards for automotive applications are a promising basis for such a maritime charging standard. However, implementing these standards comes with their own challenges which will be highlighted and discussed in this presentation. Furthermore, the local power grid is not always sufficient to supply the required Megawatt-scale peak powers. A solution for this challenge can be Energy Hubs, which is shoreside microgrids with local storage, optional local power generation and a reduced power grid connection including communications. Experiences with such microgrids and a concept for floating energy hubs will be discussed as part of the presentation.

This presentation will describe a megawatt charging system (MCS) which features either a manual or an automated connection to the vessel inlet. The charging system provides industry-leading charging speeds and consists of a high-power electronic module with a cooling device, an MCS connector with a liquid cooled cable and an MCS inlet as a mating device located on the vessel. Active cooling enables the system to provide between 1MW and 4.5MW of charging power (up to 1500VDC and 3000A). The MCS system, developed by Cavotec, also provides crucial data such as voltage, amperage and system temperature via user dashboards.

Maria Bos has more than 15 years of experience from working with innovation, digitalisation, and strategy in both the financial industry and within renewable energy. After heading the group strategy and sustainability unit in the Norwegian renewable company Eviny for some years, she was appointed CEO of Plug in 2020.

Infrastructure for high-powered charging will, inevitably, be rather costly. But it can still be cost effective, if the market is large enough and economies of scale are achievable. This, in turn, requires standardization – which is a challenge when new technology needs to be developed. CharIN (https://www.charin.global/), has years of experience in this domain, as a leading global association devoted to electric mobility, specifically interoperable systems based on the Combined Charging System (CCS) as the global standard for charging vehicles of all kinds. CharIN and the International Council on Mining and Metals (https://www.icmm.com/) have recently come together to develop the X-MCS (“extreme megawatt charging system”) to enable the full electrification of haul trucks (which can weigh over 500 tons, including 250 tons payload) and other mining equipment. This presentation will explain how we are approaching the problem.

The International Maritime Organization’s Carbon Intensity Indicator on January 1, 2023, demonstrated serious intent to cut 40% from ship GHG emissions. By 2030, many low carbon fuels proposed as drop-in combustion alternatives will not be fully ready before 2035. In the meantime, an extraordinary opportunity exists for zero emission battery power to stake its claim as a mainstream ship propulsion technology. Already used to enhance load flexibility, boost efficiency and provide zero emission power when needed, by 2022 almost 500 ships were in operation featuring shipboard batteries. At 550MWh, in service power had more than tripled since 2018. Foreship has overseen 40 ship battery installation projects, developing a five-step implementation approach for ships which spans everything from the initial case study to commissioning. It is also technical partner in Current Direct, the EU-funded project to create a battery technology and coordination solution for inland waterway and coastal transport in Europe. Foreship’s experience indicates that, as part of an integrated ship power solution, batteries can already help owners consume up to 15% less fuel. Furthermore, based on its key role in the largest ever battery installation on board a cruise ship, the company can offer unique insights into the growing hours and range available to fully sustainable stored energy. In a presentation that will outline marine battery technology developments, and explore the design, installation and approvals process, Foreship UK Managing Director, Shaun White, will quantify the truly significant impact zero emission stored energy can make on cruise industry CII objectives.

This presentation will review the experience of EST-Floattech which started 12 years ago supplying the sector with the first generation of li-ion maritime energy storage systems. Over the intervening period, it has supplied systems for over 200 projects. The review will discuss what has been learned in that period and from those projects but more importantly what those lessons provide for the development of the next generation maritime energy storage systems.

This presentation will describe a scalable and compact high-performance marine fuel cell module specifically designed for easy maintenance and servicing to ensure maximum uptime. A preventive maintenance approach, based on specific usage profiles, provides further risk mitigation utilising back-up systems, continuous monitoring and operator training.

The maritime industry claims the need for greener ships to reduce GHG and comply with new environmental regulations. The use of green technologies represents one of the solutions offered by the market. The battery system is certainly one of the most promising and proven technologies available today to meet this need. The result is a growing demand to install onboard massive battery systems with more embedded energy. Given the space and weight constraints onboard, the challenge is frequently technical rather than economic. Spear’s R&D team has developed a new solution to address this challenge. Come and discover our innovative approach!

For marine operators transitioning to zero-emission propulsion systems, hydrogen and fuel cell solutions are now certified to offer the most promising route to meet emission requirements. In this presentation Thomas Therkild Petersen from Ballard will explain why FCs have what it takes to be a catalyst in accelerating net-zero technology, and how Ballard’s DNV type approved FCwaveTM module is a true plug-and-play solution that can provide optimal replacement for conventional combustion engines onboard ships. The presentation will also feature several vessel projects which in 2023 will embark on their maiden voyages powered by Ballard’s FCwaveTM, demonstrating how zero-emission operation can be made possible here and now.

Currently there are a few chemistries that have gained traction in the marine sector. They all have their benefits and drawbacks. This presentation outlines an hypothesis that, for a number of reasons, LFP will be the chemistry that will dominate the industry until the advent of the next quantum leap in battery technology (which currently looks to be solid electrolyte batteries). This presentation will do a deep dive into the benefits and drawbacks of current chemistries and why LPF appears dentin to be the predominate chemistry of the next decade

This presentation will provide case studies and outline key challenges in designing battery container solutions, and demonstrate how the challenges were overcome by the use of effective solutions.

In December 2021, East By West Ferries (EBW) launched Ika Rere (‘Flying Fish’ in Māori), the Southern Hemisphere’s first zero emission, fully electric, fast passenger ferry. Designed and built in New Zealand by EBW's own subsidiary company, Wellington Electric Boat Building Co (WEBBCO). EBW have operated daily ferry services across Wellington Harbour, New Zealand Aotearoa, for over 35 years. Ika Rere is a 19m fully carbon fibre light-weight catamaran vessel, with a 20 knots service speed and a capacity for 132 passengers. This presentation will demonstrate the future and efficacy of sustainable marine tourism transport in the years to come.

We will dive into the system integration behind the 10 identical ferries that will operate on 3 different routes crossing Tagus River, Lisbon. Demanding light weight and high efficiency, we look at how ABB optimized the electrical system, from grid to propeller.

This presentation will discuss the solution developed by Vuyk Engineering for a full electric passenger ferry with a very challenging duty profile. The particular challenge was that the ferry route was extremely long, the speed required was high, but the berthing time for the vessel, and its opportunity to re-charge, was short. This presentation gives an insight into the development process and highlights the main challenges and important design choices. It shows that application of new technologies such as batteries have significant impacts in the overall vessel design and operation.

This presentation will provide concrete figures on the performance in different conditions of a combined Silverstream / WinGD solution. It will draw conclusions, including the potential on other ship types. Additionally, a concept for further improving the efficiency of such a system by a concept for reducing the electrical energy consumption of the ALS by integration it with the main engine will be presented.

Permanent magnet technology offers a viable method for vessel owners aiming to comply with the new IMO regulations to lower their carbon footprint. This presentation gives a brief introduction to permanent magnet technology and how it has become a standard choice in shaft generator systems and now coming to direct-drive propulsion. The main differences and benefits compared to conventional electric machines are highlighted. Case examples show what level of fuel savings and CO2 reductions are possible over a vessel’s lifetime. The most common vessel types utilizing this technology will be briefly discussed.

Upgrades to dynamically positioned (DP) vessels with the installation of Energy Storage Systems (batteries) has become very popular in recent years with the goal to reduce vessel emissions and also to minimize stresses experienced by traditional marine diesel generators during operations. Whilst this is quite a straightforward concept in theory, the actual implementation of these upgrades must be carefully managed to ensure a successful project. In this presentation Ben Hukins will present various lessons learned from upgrade projects in which DNV have been involved in order to share experience and help you with your future projects to avoid similar challenges.

Glas Ocean Electric built a proprietary data acquisition system to support the understanding of vessels' power profiles for conversion to hybrid electric propulsion. We combined machine learning with our extensive database to explore power use under different meteorological and operational conditions. The system is an intelligent, in-house-built, non-invasive commercial data collection solution for marine vessels. Sensors installed onboard provide data, including shaft torque, rpm, speed, 9-axis vessel movement, fuel flow, emissions, and wind. We present a subset of vessel power data of more than 20 workboats; we discuss the data and its application towards developing alternative marine propulsion systems.

The Wavelab electric vessel serves is a research platform for the Clean Autonomous Public Transport Network (CAPTN) initiative in Kiel. The program aims to create the infrastructure for an integrated inner-city mobility network based on multiple modes of transport on water and land. The Wavelab serves as an open platform for research and development of the required technologies for a planned clean autonomous public transport network on the Kiel Fjord. The presentation will provide an insight into the modular concept and the Torqeedo drive system that allow the integration of new technology projects. In addition the first practical experiences since the launch of the ship in spring 2023 will be shared and an exciting outlook for future projects will be given

This presentation will demonstrate how the removal of diesel gensets and their replacement by hydrogen-powered fuel cells is easily feasible — and relevant from a TCO perspective too. With the April 2023 launch of the Samana 59' Smart Electric, Fountaine Pajot's first hybridized electro-hydrogen catamaran, EODev demonstrates the path for furthering such practical developments on a larger scale. The presentation will share how to anticipate the technical approach and calculations, and how to integrate such technologies into any vessel, for new units or retrofitting.

This presentation will cover an integrated solution of energy systems, electric propulsion systems, and intelligent control and management systems. An applied case will be outlined in the presentation to elaborate on the integrated solution's performance, and capability in meeting specific demands. Compared with combustion engines, ePropulsion's integrated electric power solution excels in clean, efficient, intelligent and maintenance-free technology. Not only does it bring a better experience for users, but it also helps with significant reduction in energy consumption, noise and emissions.

Learning from our mistakes is a defining characteristic of human existence and a cornerstone of scientific advancement. For as long as humans have been building things, we have puzzled over why they fail and have used failure analysis to improve subsequent designs. The lithium-ion battery industry is no exception to this rule. Failure analysis has been an important driver for safety and performance improvements since even before Sony released the first commercial lithium-ion cell in 1991. Additionally, failure analysis can be pivotal to decisions made during legal actions involving lithium-ion batteries. However, the increasing complexity and size of lithium-ion batteries and the destructive power of large lithium-ion battery packs severely challenges conventional failure analysis techniques. In this presentation we will explore advanced techniques for understanding failures in large lithium-ion battery packs, such as those used in marine electrification applications. The implementation of computed tomography X-ray imaging (CT scanning), physical testing and incident reconstruction will be examined through the lens of a failure analysis investigation conducted on a large, rack-based lithium-ion battery pack that suffered thermal runaway creating an air-fuel deflagration event that severely injured four first responders.

This presentation will address some safety concerns learned from several incidents. It will present possible safety barriers and actual updates in the upcoming class rules for battery powered ships.

For years, large scale battery systems have been relying on relatively inaccurate methods for determining State of Health (SOH) and State of Charge (SOC). This presentation will describe a new way of managing battery data. Cloud-based assessment and analysis can pinpoint weak links in multi-MWh-systems, in real time. Battery chemistry is fundamental for TCO and above average and sustained lifetime. However, data driven optimization at the module level promises great improvements in TCO.

This presentation will describe a patented immersion cooling technology. Together with incorporated safety features it prevents cell-to-cell propagation of thermal runaway and leads to the highest safety in relation to energy density. Furthermore, the minimal temperature spread on pack and cell level enables an increased service life and reliability.

Organizations must have specific capabilities, which requires high-level manpower with appropriate skills matching with the rapid changes in maritime battery technology and consistent with the best practices of the era to have the skillset to be able to solve systemic problems. Therefore, reskilling and upskilling of the manpower is necessary, from which the academic institutes, industries and private organizations must collaborate together to fulfil this challenging target. Dr. Richter personally presents a new 3-module hybrid course with a maritime focus, which consists of an Introduction to: testing and safety of li-ion batteries.

This presentation will describe a novel cooling strategy utilising the Castrol ON E-Thermal Fluid and will show the increased heat transfer, safety and cell life benefits through practical results and modelling. TAE Power Solutions is leading the UK APC18 Celeritas project. Working with partners BMW, AMTE, BP and Clas-SiC the team have developed a modular battery system with di-electric fluid cooling, high power 21700 cylindrical cell, new control system and high efficiency DCDC converter. Based on this work, TAE will describe the optimized battery's performance

Battery testing has a significant impact on the time-to-market of batteries and electrical vehicles. Testing hundreds or thousands of batteries and cells simultaneously and efficiently in a multi-vendor lab is a huge challenge in automotive or non-automotive labs. Efficient processes and an open toolchain for automated scheduling, monitoring, energy management, and data analytics are the key aspects of a competitive battery lab. This presentation explains AVL's approach on how to optimize a battery lab operation with a comprehensive methodology supported by a dedicated software solution open for any test equipment vendor.
