Unlocking the decarbonising potential of maritime transport

Maritime transport accounts for 90% of global trade and relies almost entirely on fossil fuels. European policies push to decarbonise the sector, but hydrogen technologies must still prove their viability beyond the current 2-3 MW demonstrators. MARINER’s ambition is to provide this evidence at the 10 MW scale.

Maritime transport

MARINER will deliver a proven fuel cell system scalable to 10-MW and beyond

Our project will develop a modular 1 MW hydrogen-based fuel cell system for maritime applications, composed of building blocks that can be extended to 10MW. The system will be demonstrated in simulated maritime conditions using real ship load profiles, with the goal of 80 000-hour lifetime and an installation CAPEX of €1,200/kW.

MARINER will help accelerate the adoption of hydrogen fuel cell systems in maritime transport by reducing technical and economic risks, paving the way for cleaner deep-sea shipping.

Use cases

MARINER will demonstrate the techno-economic feasibility of the modular fuel cell system on two use cases respectively focused on the tanker and ferry applications, brought by our fleet operating partners.
