The Role of Hydrogen as Green Energy in Reciprocating Engines

Abstract

The need for fossil fuels is growing day by day with the rise in manufacturing and energy request in the world. Hydrogen is an alternative fuel with good efficiency. The hydrogen engine is capable of operating over a wide range of equivalence ratios: from ultra-lean mode to stoichiometric conditions. However, it has been observed that the engine gives maximum thermal efficiency and minimum NOx emissions and without any problems of backfire if operated within a definite range of lean operation. The fuel induction technique has been found to be very crucial to hydrogen engine development. The paper describes a path to the most characteristic features of hydrogen in reciprocating engines, and the Future sources of hydrogen production could use solar energy or Steam Methane Reforming…. etc. Finally, the paper concludes the properties of hydrogen with the main areas of research that require further efforts and the hydrogen combustion chamber.
