Why is hydrogen so important, you ask? It's a rare gas, after all. Since the COVID-19 pandemic disrupted several areas, hydrogen has fallen into the limelight. Read up on the functions of hydrogen in Towards Green Hydrogen Generation. A variety of issues and multidisciplinary approaches are presented about green hydrogen and related sectors. The book describes a gradual shift in hydrogen production technologies from non-renewable to renewable. As a result, despite the uncertainty created by the pandemic, efforts to build a more sustainable environment have gained momentum. This volume covers hydrogen issues by presenting the relationships and opportunities in these related sectors. Organized into three parts, Towards Green Hydrogen Generation introduces and discusses crucial topics on hydrogen. Part 1 is dedicated to the current state and challenges encountered in the industrialization of green hydrogen production. Part 2 recognizes carbon-capturing and hydrogen-related learning models. The last entry introduces green hydrogen generation, PEM water electrolysis, and other electrolyzers.
