The TRL of onboard storage (4,3) and propulsion (5)* of HYDROGEN still need to mature further. There are several projects ongoing that investigate the use of compressed and liquid hydrogen in both internal combustion engines (ICE) and fuel cells (FC), all applied in smaller vessels. Further RD&I in the form of demonstrators is needed to investigate the best fit regarding vessel type and operational profile for this technology.
