The Essence of Hydrogen Fuel in Harmonizing Energy Supply and Environmental Safety Zelalem Tekulu

Abstract

In this article, the essence of hydrogen fuel in harmonizing energy supply and environmental safety is reviewed. It is found that, currently, hydrogen is produced globally about 50% through steam reforming of natural gas, 30% through oil/naphtha reforming, 18% through coal gasification, 3.9% through water electrolysis, and 0.1% through other sources and methods. That is, globally, 4% of H2 is producing from renewable and sustainable sources with no environmental pollution. In most cases production of H2 in large scale from renewable and sustainable sources with no environmental pollution is not matured and widespread. However, H2 is a globally accepted clean and sustainable fuel when it is produced from renewable sources such as biomass and water through processes with no environmental pollution. Mainly H2 is clean fuel for all end user applications since its application in fuel cells and combustion engines never release green house gases.
