Hydrogen: A Future Chemical Fuel

Abstract

A chapter on “Hydrogen: A Future Chemical Fuel” provides a basic knowledge of hydrogen energy and its importance in modern society. Nowadays, the development of hydrogen energy has shown a tremendous attraction of today’s researchers because it is a source of clean energy (i.e. green energy) and most abundant element in nature. The excellent properties of hydrogen such as high-energy content (~141.86 MJ kg−1), environment friendly nature, sustainability, etc. prove it as a highly acceptable green fuel. The main idea behind this chapter is to describe the understanding of the necessity of H2 energy, production of energy, storage, the challenges, and hopes towards the development of system infrastructure, and the most important is applications of Hydrogen Economy. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
