I. Introduction
The commercial exploitation of fossil fuels began in the 19th century [1]. Ever since then, it has transitioned from a valuable to a necessity to a crutch for human existence. It plays an integral role in most processes that require energy, which only serves to increase its detrimental impact on the earth and its inhabitants. This has inspired a great deal of interest and innovation in alternate energy sources, such as solar and wind energy. The earth presents a bountiful supply of hydrogen, which takes up over 75% of the universe due to its presence in various chemical compounds. Presently, the entire worldwide hydrogen production is around 500 billion cubic meters per year [2]. This is one reason why the field of hydrogen warrants interest. Another reason would be because of various policy makers aiming to decarbonize the energy sector in an attempt to mitigate the effects of climate change. This paper presents the research done on green hydrogen, its viability and advantages, and how it compares to other alternative energy sources.
