Hydrogen for Maritime Applications

Detailed overview of innovation with sample startups and prominent university research

What it is

Hydrogen for maritime applications involves using hydrogen as a fuel source for ships and other vessels, offering a clean and sustainable alternative to traditional marine fuels, such as heavy fuel oil and diesel. This transition is crucial for decarbonizing the shipping industry, a significant contributor to greenhouse gas emissions and air pollution.

Impact on climate action

Hydrogen for Maritime Applications within the Green Hydrogen theme revolutionizes climate action by providing a clean energy source for maritime transport. By replacing fossil fuels with green hydrogen, this innovation reduces maritime emissions, mitigates air pollution, and advances the transition to sustainable shipping, combating climate change and protecting marine ecosystems.

Underlying
Technology

Hydrogen Fuel Cells: Hydrogen fuel cells convert the chemical energy of hydrogen into electricity, which can then power electric motors to propel the ship. This approach offers high efficiency and zero emissions, making it a promising solution for sustainable shipping.
Hydrogen Combustion Engines: Hydrogen can be directly combusted in modified internal combustion engines to generate power for propulsion. While this approach still produces some emissions, it offers a lower-carbon alternative to traditional marine fuels.
Hydrogen-Derived Fuels: Hydrogen can be used to produce other low-carbon or zero-carbon fuels, such as ammonia and methanol, which can be used in existing marine engines with minimal modifications.
Hydrogen Storage and Bunkering: Hydrogen-powered ships require infrastructure for hydrogen storage and bunkering (refueling). This includes developing safe and efficient storage solutions, such as compressed hydrogen or liquid hydrogen tanks, and establishing bunkering facilities at ports.
