Case studies for battery-powered mid-size vessels

Peter Lystrup Christensen
Head of technology systems
MMKM Center for Zero Carbon Shipping
Denmark
Battery-powered vessels have recently entered the shipping business in applications with short ferry crossings or hybrid installations. Continuous rapid development of battery performance and cost, along with its inherently superior well-to-wake efficiency, begs the question as to what needs to happen with battery cost and performance to make them viable for deep sea shipping. This presentation will offer a study that tries to address these questions by identifying barriers, gaps and required development; operational issues and relevant vessels; charging infrastructure and potential WTW impact of battery-powered vessels.

The challenges to ship owners in the decarbonization process, and the responsibilities of equipment manufacturers.

Elias Boletis
Chair
CIMAC Working Group 10
Netherlands
This presentation will unpick the questions which arise about the drivers of technological progress towards decarbonisation in the marine sector. Are they pulled along by demand from ship owners or pushed forward by equipment manufacturers? What are the implications of either approach? Which would be best and should either do more of the same, less or something entirely different? Elias Boletis is uniquely placed to provide insight into these questions. He is responsible for the CIMAC Working Group 10 ‘End Users’. These are primarily ship owners and provides a link between the ship owners and the equipment manufacturers for the marine sector.

Challenges of assessing multi-component powertrains in the early design phase

Lukas Kistner
Senior researcher
HD Hyundai Europe R&D Center
Germany
Modern ship powertrain designs are integrating shaft generators, fuel cells, and batteries to enhance energy efficiency and reduce CO2 emissions. However, due to the diversity of vessel characteristics, a universally best-performing design is not conceivable. Instead, different technologies, each with their unique efficiency characteristics and operational limitations, are favored, also necessitating tailored system control strategies. Lukas Kistner introduces an early-stage modular energy management approach aimed at operational efficiency and flexibility, which can be used for model-based system design optimization tasks.

Shipowners need cleaner, smarter fleets to be competitive. Their ship systems need to have clear advantages through emerging technology for situational awareness; be flexible for lifecycle technology insertion; be efficient, available and sustainable; manage costs and risks through sensing, automation and controls; be able to operate with less or no human intervention; and enable communication. This presentation will look at enabling lifecycle performance through the ship’s electric grid and will show how electrification enables the efficiency and connectivity of systems in vessel networks, the electric network trends in hosting more sustainable solutions and enhanced automation over life and the impact on the vessel lifecycle from availability to decarbonization. The presentation will also offer a truly innovative and groundbreaking concept of an electric drivetrain technology, combining an electrical rotating machine and associated power electronics.

Surfing the wave of cleantech: integrating marine fuel cell systems

Jonathan Brown
Strategy director
Hypermotive
UK
Hydrogen fuel cells undoubtedly play a part in the future of marine power. The use of hydrogen, or its derivatives, is one of the few options for sustainable operation satisfying such energy-intense requirements. However, the skill sets and technologies to integrate these systems into maritime’s demanding environments are limited. The cost of developing bespoke fuel cell systems specifically for marine is prohibitive; a new approach, relying on the successful transition of products created for a broad range of sectors, must be deployed. This presentation will provide examples and insights into some of the challenges, innovations and opportunities arising on this journey.

Ensuring safe huge battery installations for crew, cargo and vessels

Asbjørn Halsebakke
Senior manager, marine concepts
The Switch
Norway
Bigger battery systems are being installed on vessels all over the world, which is good. But can we be sure that the potential short circuits behind these huge energy sources are controlled or have even been considered? Solutions have been developed that reduce the potentially high short-circuit levels in marine applications to a level that even the smallest converters can handle. This presentation will discuss the potential short-circuit levels of different battery chemistries and how to reduce the energy introduced to a short circuit to only a small percentage of the energy that looms behind, with a short-circuit current limiter.

Calendar life degradation and how to size for it

Johan Winlund
Manager
Echandia Marine AB
Sweden
Nickel-manganese-cobalt (NMC) and lithium titanate oxide (LTO) batteries have emerged as frontrunners in marine energy storage solutions. Despite their potential, they suffer from calendar life degradation. This not only undermines battery efficiency but prompts operators to preemptively oversize installations. This inflates costs and environmental impacts. The assumption that excess capacity will offset the inevitable decline, however, overlooks critical factors like the effects of intermittent charging, depth of discharge preferences and temperature variations, which collectively can lead to premature capacity loss, thereby nullifying the perceived safety net of oversizing. A paradigm shift is warranted in marine battery sizing: from a conservative stance to an informed, analytical one. Emphasizing the intricacies of calendar life and the factors affecting it allows for a balanced solution that promotes both economic and environmental sustainability. This presentation invites the maritime industry to embrace a strategy that enhances the long-term viability and performance of marine energy storage systems.

Using current oil infrastructure for hydrogen storage

Thorbjørn Hareide
Business development manager
Hydrogenious LOHC Maritime
Norway
Liquid organic hydrogen carriers (LOHC) are organic compounds that can absorb and release hydrogen through chemical reactions. These compounds serve as storage media for hydrogen. LOHC technology therefore adds a new way of handling hydrogen on board ships. Instead of using compressed or liquid hydrogen, hydrogen is chemically bound to a carrier oil. This oil can be used to store and transport large amounts of hydrogen safely within existing fossil fuel infrastructure. With our ongoing projects we aim to develop a commercial LOHC power system that can utilize hydrogen as a power source on board ships in the safest way possible.

Protecting the environment without compromising performance – hybrid case study

Tobias Kohl
Director application engineering marine
Rolls-Royce Solutions
Germany
Liberty Lines operates a fleet of 30 high-speed passenger craft, providing a fast and reliable ferry service for more than three million passengers annually between mainland Italy, Croatia, Slovenia and the Sicilian islands of Egadi, Pantelleria, Pelagie and Ustica, and in the UNESCO World Heritage-listed Aeolian islands. In 2021, Liberty Lines embarked on a plan to renew its entire fleet of high-speed ferries while aiming to minimize the environmental impact of its operations. The operations demand the carrying of 250 passengers per ferry at a cruising speed of at least 28kts. Some of the longer crossings are nearly 100 nautical miles, and therefore propulsion solutions based on pure batteries or hydrogen were concluded to be not technically feasible. Liberty Lines contracted for 12 new vessels, the first to obtain RINA Green Plus classification. They will navigate in fully electric mode near ports and will then be able to recharge their batteries in the open sea. During long periods of stopover, the ships will use cold ironing to recharge the batteries and keep all the onboard services active to help lower the CO2 footprint. This presentation will provide a more detailed overview of this exciting project.
