"Toyota continues its lonely crusade to make the oft-promised hydrogen future happen, this time expanding from trucks, cars, and Popemobiles into more… “liquid” arenas. And by that, I mean: Toyota is developing a hydrogen fuel cell for marine applications.
It’s called the REXH2, and it’s a modular power system designed to be easily integrated into existing naval architecture. Much more than a concept, the REXH2 already seen more than 7000 nautical miles’ worth of real-world use plus a trans-Atlantic crossing aboard the Energy Observer. Toyota says this proves that “silent maritime and river mobility without emissions of CO2 or fine particles (is) possible.”"
