Is Green Hydrogen a Potential Sustainable Fuel?

Abstract

Environmental and anthropogenic factors engendering the rise of environmental carbonization have led to a global growing appetite for introducing the use of sustainable energy in governmental policies. Nowadays Green hydrogen has been brought in the spotlight and recognized as a green alternative to fossil fuels because it is presently enjoying a momentum widespread in Markets, countries, and companies. Hydrogen /energy have shared a long period of history during which hydrogen has gained a great chunk of support from different countries though the wrong starting point. If it is competed by other sources of energy green it has been then adopted as the best energy source in several countries such as Germany, China, the USA, Japan…..because hydrogen is regarded as a ‘missing piece in the carbon-free energy puzzle’: it is a clean energy career which its sustainability and versatility contributing in decarbonizing the environment due to its near-zero carbon missions, as well as  a cost-effective production, and as a cutting edge sustainable and technological production, especially in the domain of mobility. That is why it is used as a fundamental fuel in various applications: energy storage, mobility, and in the industrial field, through three types of processes: thermochemical, electrolytic, and biological Processes. Although green hydrogen is recognized as a promising energy vector, it has some drawbacks that ‘should be borne in mind’ such as  high production costs, and greenhouse gas emissions.
