About the project

The HELENUS project will develop and demonstrate a High Efficiency Low Emission Nautical SOFC on a large ocean-going cruise vessel. This 500 kW TRL 7 SOFC solution will create a blueprint for scaling up the system up to 20 MW in future ship builds. Operating in cogeneration mode, the SOFC will simultaneously produce both power and heat, unlocking up to 23% efficiency gains in a scaled-up system. HELENUS will also demonstrate the fuel-flexibility of SOFCs with alternative renewable fuels over various maritime duty cycles. Through collaboration between key stakeholders from all sections of the maritime value chain, HELENUS will pave the way towards climate-neutral shipping.
