Stationary hydrogen combustion engine
The WTZ engine and machinery research center in Roßlau chose a different path to developing a new stationary zero-emission system. It designed an air-independent propulsion engine called H2 DI Zero. The name stems from the fact that some of the combustion gases are recovered so the engine emits nothing but steam. Instead of air, it uses argon, an inert gas that can be retrieved multiple times over, and pure oxygen, mixed with hydrogen.
