Market Definition
Hydrogen IC (internal combustion) engines are a type of internal combustion engine that operates using hydrogen gas as its primary fuel source. Similar to conventional gasoline or diesel engines, hydrogen IC engines combust hydrogen within their cylinders to produce mechanical energy, which is then used to power vehicles or machinery. The combustion process involves injecting hydrogen into the combustion chamber and igniting it with a spark plug. Unlike traditional engines, hydrogen IC engines produce water vapor as the primary byproduct, making them environmentally friendly in terms of emissions. These engines can be adapted from existing gasoline or diesel engine designs with modifications to accommodate hydrogen fuel injection and combustion characteristics.
