The only things I see as the real detriments to the system (other than the $$) are the limited range (300 mi, how would a diesel powered vessel compare ?) and the "recharge time".
The 17kg of H storage theoretically has 2281400 Btu or 689 kwH of energy. With 900w (0.9kw) of power generation on board and assuming 85% efficiency in electrolysis (to get the H from H2O) and 95% in storing the H into the Ovonic's "battery", it'll take some 38+ days to recharge all the H. Better have shore power at the dock
Still I am very enthused about the usage of the "H battery", aka Ni Hydride hydrogen storage. This technology is possibly 1 of the key elements to getting hydrogen fuel cells into auto usage (and solving the leakage problem).
