Hydrogen, Chronology and Electrochemical Production

Abstract

Human gluttony is having a catastrophic effect on the environment. Since the age of industry and the world wars, modern societies have hygienically depleted most of the earth's resources, thus depleting all the resources that will be essential for future generations. The problem doesn't stop there: greenhouse gas emissions have significantly increased the earth's temperature, causing terrible damage to the climate. The production of green energy with no greenhouse effect seems essential to save the planet. Green hydrogen is a suitable and promising way to generate an energy source that produces H2O molecules instead of CO2. Water electrolysis is a very important technique for producing green H2 using an appropriate electrical current generated by a non-polluting energy source such as wind turbines. This review presents a historical and technical overview of the hydrogen element from its discovery to its current production. Throughout this work, we have tried to deal with the most significant historical periods.
