Maritime vessels that recharge often or have enough energy storage capacity can achieve zero-emission operations using batteries alone. However, to maintain zero-emission levels over longer periods of time and for larger vessels, other technologies are required.
As the marine sector pursues carbon reduction goals, using energy storage and fuel cell systems together with a green fuel source, such as hydrogen, shows promise to accelerate maritime decarbonization.
With this combination, vessels can maintain zero-emission operations for longer without refueling or recharging, ideal for operations in emissions-restricted ports, harbors and zones.
Using battery and fuel cell systems together improves energy efficiency. Battery systems handle load variations and peaks, enabling the fuel cell systems to continuously operate at the most efficient load levels. This optimized power distribution extends the range of zero-emission operations and the lifetime of both systems.
This presentation will explore the opportunities and challenges in adopting the combined use of batteries, fuel cells and green fuels, and will provide real-world case study examples.
Key topics will include:
- An overview of advancements in marine battery and fuel cell system technologies, how the systems work together, and the benefits for vessel owners and operators.
- Green fuel considerations including production, transportation, bunkering, storage onboard vessels, safety and regulations.
