Chemical Kinetics of Hydrogen Combustion

Hydrogen is a simple, lighter, and common element found in the composition of many materials, especially fuels of interest. With growing interest toward hydrogen being a non-carbon fuel and its potential toward decarbonizing the aviation and power industry. It is necessary to understand the fundamentals of hydrogen chemical kinetics. The chapter reviews and discusses the critical elements of hydrogen chemical kinetics by introducing the basis of chemical kinetics and exploring possible reaction pathways for hydrogen oxidation with oxygen and air. The critical reactions of major intermediate species and NOx emissions are emphasized. The effect of considering appropriate intermediate species like HO2 and H2O2 are discussed and provided a brief on the explosion limits of H2–O2 along with ignition delay and laminar speeds.
