Abstract: Hydrogen is recognised as the fuel of the future and a key component for sustainable energy transition in all spaces that currently use fossil fuels, such as the electricity, transport, and industrial sector. The most widely used hydrogen production process is water electrolysis and often requires large amounts of energy. However, to obtain clean hydrogen, it is essential that it comes from renewable and sustainable sources. Therefore, this article reviews the most recent advances in green hydrogen production technologies published during the 2019-2023 period. A global overview of green hydrogen production is compiled in this article, and studies on the mechanisms of electrolysis, photocatalysis and thermochemical cycles for water decomposition are also presented, as are new strategies for integrating technologies and efforts designed to make production more sustainable and competitive with conventional methods. Thermochemical cycle technology, it was identified as one of the most promising to produce green hydrogen.
