The Hydrogen Engine is a block used to generate power by consuming Hydrogen. It isn't very useful as a primary power source, as most of its power output would be required to operate sufficient O2/H2_Generators to keep it fueled. Instead, it functions best as an intermittent low-MW power source used along with external hydrogen storage.
The engine has an internal hydrogen tank that is only refilled while the engine is actively running.
- Kind of sucks
