Patent ID: 11815036

Abstract:
A vehicle, system, and method include a first tank configured to contain compressed gaseous fuel, such as hydrogen, and a second tank fluidly couplable to the first tank and an internal combustion engine, the second tank configured to store the gaseous fuel from the first tank in a communal cavity with a non-combustible liquid, such as water, without a bladder or physical separation barrier therebetween, and to selectively deliver the gaseous fuel via a first outlet, and the non-combustible liquid via a second outlet, to the internal combustion engine. A turbine may be disposed between the first and second tanks. One or more condensers may condense water from engine exhaust and/or an air conditioning system and pump the liquid water into the second tank. Pressure within the second tank may be controlled via fuel supplied by the first tank and/or liquid supplied via the condensers and pump.
