The production and escalation of hydrogen on a large scale is a goal toward the upheaval of green and cheap energy. During the last decades, many methods have been espoused to produce more hydrogen fuel. Right now hydrogen is hauled out from different sources, such as oil, coal, natural gas, water, etc. In case of water, the hydrogen is produced by different methods such as electrolysis, photosplitting, photoionization, photocatalysis, product analysis methods, etc. This review paper thrashes out the assessment of these assorted methods of hydrogen production from water.
