Hydrogen Fueled Internal Combustion Engines as One of Power Sources Leading to Hydrogen Energy Society

Abstract

Hydrogen fuel internal combustion engines have been studied and developed for a long time. Thanks to the no carbon element in hydrogen, hydrogen never generates any CO₂ after the combustion. In the time when the greenhouse effect caused by CO₂ in the atmosphere is crucial all over the world, the reduction of CO₂ generated by the fossil fueled internal combustion engines is more urgently required. As one the leading power generators, hydrogen fueled internal combustion engines can work well to reduce CO₂ in the atmosphere, leading earlier to the hydrogen energy society. And the hydrogen fueled internal combustion engines have advanced a lot these 20 years especially in the thermal efficiency. In addition of the tendency of the renewable energy toward larger amount and smaller price, it is expected for the hydrogen fueled internal combustion engines to make a swift debut into the society.
