Review of Research on Production Methods of Hydrogen: Future Fuel


Dr. R. Hema Krishna

Hydrogen is considered to be the most viable energy carrier for the future. Hydrogen is high in energy content as it contains 120.7 kilojoules/gram. This is the highest energy content per unit mass among known fuels. This paper provides a comprehensive review of the various Physico-Chemical Production methods(Fossil Fuels ,Steam Reforming of Natural Gas, Thermal Cracking of Natural Gas, Partial Oxidation of Heavier Hydrocarbons,Coal Gassification, Water, Electrolysis, Photolysis, Thermochemical Process, Thermolysis) & biological approaches (Bio-Photolysis of water, Photodecomposition of organic compounds, Fermentative Hydrogen Production from Organic Compounds, Hybrid System) that are being studied for biohydrogen production. A succinct discussion of production techniques for enhancing hydrogen production from Physical-Chemical Production has also been provided where Steam reforming of natural gas is currently the least expensive method of producing hydrogen, and used for about half of the world's production of hydrogen, where as in biological approaches Hybrid System have been found to be among the best production technologies for enhanced biohydrogen production.
