Clean and competitive solutions for all transport modes (HORIZON-CL5-2023-D5-01)

TOPIC ID: HORIZON-CL5-2023-D5-01-11

Project outputs and results are expected to contribute to the following expected outcomes:

  • Establish the basis for the on-board deployment of power conversion technologies for sustainable alternative climate neutral fuels by 2030;
  • Validate the technical feasibility of the use of innovative power conversion technologies for sustainable alternative carbon neutral fuels in waterborne transport;
  • Prove the scalability to power outputs significantly above 3 MW with acceptable power density and high efficiency; Validate achievement of the additional KPIs of; minimum 5 kW/m3 power density (refers to power density of the energy converter, i.e. excluding storage of fuel or liquid electrolytes); minimum 45 % total system energy efficiency including all required ancillaries with zero carbon or climate neutral operation weighted over the MARPOL Annex VI E2 or E3 cycle;
  • Support regulatory development within both EU and IMO frameworks;
  • Prove the safety of the proposed solutions through verifiable KPIs for the use of the fuel and power conversion system concerned;
  • Validate resilience of the power system to possible fuel impurities and variability of the power required by the ship;
  • Developed a realistic pathway to the wider use of power conversion system technologies in waterborne transport (e.g. Long Distance, Inland, Cruise, Ferries, Short Sea and Offshore);
  • Risk assessed the power conversion system with respect to lifetime, maintenance scheme and life cycle cost as well as a life cycle GHG emissions;
  • Where relevant, be coherent with the activities of the Batteries co-programmed partnership and the Clean Hydrogen Joint Undertaking.
