Hydrogen Fuel Cells Identified to Decarbonise the Maritime Sector

Hydrogen and fuel cells have been identified by the International Maritime Organisation as a crucial technology to decarbonise the sector. Fuel cells have a higher efficiency and density than fossil fuels allowing vessels to travel further with reduced fuel consumption. As the energy is created through a chemical reaction there are no moving parts, enabling silent operation, lower maintenance costs, improved performance and increased lifetime.

Hydrogen fuel cells are highly recyclable and use of renewable energy in the form of green hydrogen creates a zero emissions energy chain. This technology enables a lower impact (both local and global) on a vessel’s emissions to air making it a chosen solution to decarbonise the maritime sector.

Genevos provide a range of zero emissions power solutions to meet energy needs from 15 kW to 500 kW. The HPM family includes a 15 kW, 30 kW and 40 kW that can be connected in parallel to decarbonise vessels through auxilliary, primary or hybrid integration. This scalable solution can be applied across the maritime sector from small to large vessels including yachts, ferries, service vessels, inland transport and shipping.

The HPM family is tested and certified to the highest standards of marine commercial operation.

HPM Overview

How PEM fuel cells work

Similar to batteries, fuel cells operate with electrochemical reactions between the anode or cathode and the electrolyte membrane, but with continuous fuel and air supplies.

When hydrogen comes in contact with the catalyst, the hydrogen splits into protons and electrons. The protons pass through the proton exchange membrane unimpeded and proceed to the cathode side, while the electrons are blocked and forced to travel through an external circuit. As they travel along the external circuit, they provide the electricity needed for auxiliary power or to drive a motor. Eventually the hydrogen protons and electrons reunite and combine with oxygen to produce water.
