The overall objective of SEABAT is to develop a full-electric maritime hybrid concept based on combining modular high energy batteries and high-power batteries, novel converter concepts and production technology solutions derived from the automotive sector. A modular approach will reduce component costs (battery, converter) so that unique ship designs can profit from economies of scale by using standardised low-cost modular components. The concept is suitable for future battery generations and high-power components that may have higher power densities or are based on different chemistries.

Expected results:

  • Optimal full-electric hybrid modular solution, minimising the battery footprint and reducing the oversizing (from up to 10 times down to max. 2 times).
  • Validating as a 300 kWh system (full battery system test) at TRL 5, and virtually validating the solution for batteries of 1 MWh and above, using 300 kWh system P-HiL tests.
  • The result will be a validated hybrid battery solution for capacities of 1 MWh and beyond, a roadmap for type approval and a strategy towards standardisation for (among others) ferries and short sea shipping.
  • The solution will deliver a 35-50% lower total cost of ownership (TCO) of maritime battery systems, including 15-30% lower CAPEX investment, 50% lower costs of integration at the shipyard and a 5% investment cost recuperation after the useful life in the vessel.
