Hydrogen Internal Combustion Engine

Abstract

Hydrogen fuel constitutes an attainable alternative strategy, which can be implemented in the long term. This strategy can avoid the risk of commodity supply dependency (rare earths and copper) and can delay the still open decisions on e-mobility. Hydrogen internal combustion engines represent a doable and less expensive solution for using hydrogen than purchasing a new car equipped with a hydrogen fuel cell. Conventional piston engines can be switched to gas operation with relatively little change. This approach is environmentally more viable, as in a short time most vehicles can be switched to emission-free operation. Also, it can avoid the risk of commodity supply dependency (rare earths and copper) and can delay the still open decisions on e-mobility.
