Renewable hydrogen production has an opportunity to reduce carbon emissions in the transportation and industrial sectors. This method generates hydrogen utilizing renewable energy sources, such as the sun, wind, and hydropower, lowering the number of greenhouse gases released into the environment. In recent years, considerable progress has been made in the production of sustainable hydrogen, particularly in the disciplines of electrolysis, biomass gasification, and photoelectrochemical water splitting. This review article figures out the capacity, efficiency, and cost-effectiveness of hydrogen production from renewable sources effectively comparing the conventionally used technologies with the latest techniques, which are getting better day by day with the implementation of the technological advancements. Governments, investors, and industry players are increasingly interested in manufacturing renewable hydrogen, and the global need for clean energy is expanding. It is projected that facilities for manufacturing renewable hydrogen, as well as infrastructure to support this development, would expand, hastening the transition to an environment-friendly and low-carbon economy.
