Advances and future challenges for hybrid and all-electric propulsion in the 21st century

Luke Briant
director - marine solutions Americas
Siemens Energy Inc
USA
As marine technology has evolved, diesel-electric propulsion (DEP), hybrid and all-electric power and propulsion systems have become the new norm. Hybrid and all-electric propulsion have been centered around lithium-ion battery energy storage systems (ESS) with the long-standing promise of dramatic improvement in battery performance with future technology development. Discussions about the limitations of battery systems have focused on safety and limited energy storage capacity: safety targeting susceptibility to catastrophic failure due to thermal runaway, and limited energy storage capacity focused on energy density and the space/weight limitations associated with this on board a vessel. The latest trends in the marine industry have focused on hydrogen-based propulsion for blended hydrogen fuels for internal combustion engine (ICE) applications, and the use of fuel cell (FC) technology. With ESS requiring supercharging, and hydrogen-based systems requiring fueling, challenges in our industry have become apparent. Limitations, solutions and future expectations associated with this both globally and in the USA will be discussed.

Lithium-ion battery failure modes and using advanced failure analysis techniques to drive innovation and improve safety

Kevin C White
principal scientist
Exponent
USA
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 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.

New hybrid ADC technology: the best of both worlds

Michael Davis
director
DEWESoft
USA
This presentation will describe a new hybrid analog to digital converter which offers both a high bandwidth mode and a high dynamic alias-free mode. The high bandwidth mode can perfectly acquire impulse, step and square signals; a mode typically found in SAR ADCs. The high dynamic alias-free mode is used for frequency domain analysis, like sound and vibration and similar to classical Sigma-Delta ADCs. Currently, users would require two separate DAQ devices for these measurements. This new technology, which provides both modes in one device, is encompassed within the SIRIUS XHS DAQ system which does not require any complex setup or programming knowledge. DewesoftX data acquisition software offers unbeatable plug-and-play simplicity. These and many of the other features of the technology will be outlined.

The implications of electric motor power curves for vessel propulsion

Donald MacPherson
technical director
HydroComp, Inc
USA
Alex Walker
naval architect
HydroComp, Inc
USA
Many prime movers are principally defined by their rated power and RPM. However, the full picture of power delivery must consider the power above and below the rated RPM. This is represented by what has come to be called a 'rated power curve' which can vary greatly between different prime mover types, such as internal combustion engines (ICE) and electric motors (EM). The effect of curve shape on vessel performance and propulsor selection can be significant, particularly for those considering EM prime movers for their vessels. This presentation will describe the differences between ICE and EM power curves, as well as discuss the implications of EM power curves for different operating modes (such as transit or towing), continuous versus peak conditions, considerations for motor overload and partial load efficiencies. A case study will demonstrate propeller selection decisions for an EM application with calculation of operational current demand.

16:10

Integrated model-based design using hardware-in-the-loop (HIL)

Matt Baker
vice president of grid modernization
Typhoon HIL Inc
USA
The increasing electrification of shipboard power systems requires high-fidelity modeling and simulation capability to verify and validate system performance during the design and construction of the vessel. At the same time, there is a requirement to test the tens of thousands of lines of code running on digital controllers that are the norm. A solution to test both electrification and digitalization demands is required. Typhoon HIL provides an integrated model-based design process using hardware-in-the-loop to address the requirement.

Theater 2 US policy landscape for the maritime industry

DC switchboards in combination with new energy sources

Roger Sandnes
VP sales North America
Vard Electro US
USA
Vard Electro sees plug-in potential for green energy sources as the industry faces an AC/DC dilemma on transmission networks. Green energy technologies such as batteries, fuel cells, solar and wind are on the rise in shipping, but these will require a shift in existing power distribution systems on board vessels to realize gains in fuel efficiency and environmental performance. Diesel-electric systems with engines running at fixed speed have typically used AC (alternating current) switchboards, or power grids, to supply power for propulsion systems and thrusters, alongside frequency converters to control propeller speed for greater efficiency. However, the use of AC switchboards is now being challenged by the emergence of renewable energy sources and energy storage systems mostly using DC (direct current) that require multiple DC-AC conversion, meaning more components with greater complexity and less control of the power system. This has increased the focus on the potential advantages in terms of controllability, flexibility, cost savings and reduced fuel consumption of DC switchboards, which were first developed about a decade ago but have so far only been installed on a limited number of vessels such as hybrid and all-electric ferries, PSVs and fishing vessels. Vessels with variable loads are dynamic position vessels, fishing vessels, ferries, all vessels that may be upgraded in the future, vessels with a high amount of VFD loads, well boats, cable-laying vessels, etc.

Preserving ESS lifetime during the design phase – sensitivities, margins, and the importance of robust EPLA

Kevin Andersen
technical solutions manager
ABB Inc - Marine & Ports
USA
By comparison with conventional diesel mechanical systems, ships employing zero-emission technology generally carry significantly less energy onboard. In the case of battery electric ferries, some vessels may only take as much energy required for a single trip. Any unplanned hotel load growth or inaccuracies in the initial load profile used in the design phase may result in deeper than anticipated discharges, thus causing premature ageing of the ESS. This presentation will discuss the paradigm shift needed in the classical ship design spiral to prioritize early robustness in the EPLA early, while managing uncertainty and potential areas of load growth through the use of margins. The session will present several case studies showing identifying the ESS’s economic life sensitivity to minor load changes and ramifications with shore charging capacity, and the economics of premature ESS replacement.

Electrifying vessels and energy storage solutions for zero-emission ports

Guillaume Clement
vice president e-marine
Leclanché Norway AS
Norway
The world’s transportation infrastructure is moving rapidly toward the use of electric vehicles – cars, trucks, buses, trains and more. But when it comes to maritime vessels, the equation is a bit more complicated since there aren’t any ‘charging stations’ out at sea.

From maritime port microgrids that seek to save money by being self-sufficient and grid form but remain connected to the supergrid, to systems for ships where power electronics and switchgear are combined to reduce integration risk, to the fusion of power electronics and propulsion motors to save space, traditional boundaries between equipment and functions are changing. This presentation offers an insight into these topics from the HV connection bringing power to the port, through the port microgrid, onto the ship and down to the propeller.

Magnetic plugs – the new standard for e-boat charging

Sanad Arida
CTO
VoltSafe
Canada
Conventional pronged plugs are fraught with flaws: corrosion and arcing can cause fires; plugs are not always connected properly and can be dislodged quite easily even if they are. What is required is a foolproof system that connects smartly and accurately and stays connected safely throughout the charging process. VoltSafe technology replaces prongs with magnets similar to Apple’s MagSafe. The system can accommodate not just recreational but also commercial vessel requirements and sets a new standard for electrical safety in shore power. This presentation will describe the system, its technology and the benefits it brings to shore power systems.

Electric propulsion: a future-ready drivetrain for your ship

François Lessard
president & CEO
Techsol Marine Inc
Canada
Electrification is not the future. It’s now, and it is for everyone. Ships are built for 40+ years and whatever is built today needs to be ready for tomorrow, even if we don’t know yet which alternate energy source will become dominant. An electric propulsion is the first building block so your ship can harness those alternate energy sources in the future, whichever ends up on top. Even if today’s energy sources don’t seem to fulfill your requirements, it’s highly probable they can. For instance, diesel engine use optimization, operations coverage and charging infrastructure are amongst the key challenges to meeting environmental damaging emissions reduction targets. A few creative approaches are possible and some of them will be explained in this presentation.

Unlocking the potential of waterborne public transportation

Erik Eklund
CEO commercial vessels
Candela Technology
Sweden
This presentation will offer a case study of Candela’s P-12 Shuttle, the world’s first all-electric hydrofoiling passenger ship. It will hit Stockholm’s waterways in 2023, shuttling passengers to and from the archipelago above the waves and without wake, noise, exhaust fumes or oil leaks. The vessel, developed by Stockholm boat builder Candela Technology, consumes about one-tenth the energy of a conventional ship and is comparable to a modern electric-hybrid bus, making it the most energy efficient, fast ship ever built. It is also based on Candela’s electric hydrofoil technology that has been in serial production since 2019 for leisure boats. This technology pushes the performance boundaries of electric boats and ships and allows us to rethink public transportation.

Electric fast ferries are viable today

John Carroll
president
Green City Ferries Americas
USA
Zero-emission fast ferries are viable today. Advances in batteries, fuel cells, vessel design and innovative financing make them a real choice. Advanced LTO marine batteries are safer, charge three times faster and have a service life five times longer than previously. Vessels with lower weight (carbon fiber) and less friction (foil-assist) use less energy and have longer range. In addition, standardized, serial production together with a single platform (battery and fuel cell) make them great value. With innovative finance (e.g. Boatplan Stockholm 2025), long-term bareboat charter allows ferry operators to get started immediately.
