Abstract
Upcoming hydrogen economy is on rise on political agenda due to growing need of hydrogen. Natural occurrence of hydrogen cannot satisfy the present need of hydrogen. It produces a wide gap between current hydrogen requirement and amount of hydrogen present in earth. To counter this problem, hydrogen is produced commercially in industries through various methods. Among all these methods, SMR (Steam Methane Reforming) process is considered most feasible for being economically cheap as compared to other methods. Being economical does not necessarily mean being eco-friendly. Industrialist does not switch on alternative methods and continue using SMR process which is producing a devastating impact on atmosphere by increasing the amount of CO2 (carbon dioxide). Greenhouse effect of carbon dioxide makes it one of the primary sources of increasing global warming in earth's atmosphere. Apart of other uses, Hydrogen can also be used as eco-friendly energy source as compared to fossil fuel used as energy source. In this paper, the procedure of production of hydrogen through SMR process is reviewed in detail and its pros and cons are discussed.
Highlights
Natural gas, solar heat, gasoline and diesel serve as energy source to drive this world [1, 2]
Steam methane reforming process is more efficient as compared to other methods of production of Hydrogen
Production of hydrogen through steam methane process produces about 99.9% pure hydrogen which can be used as alternative energy source but produces huge amount of carbon dioxide which will affect earth’s atmosphere indirectly
Summary
Natural gas, solar heat, gasoline and diesel serve as energy source to drive this world [1, 2]. Some more uses include mixture of hydrogen and nitrogen in synthesis of ammonia and mixture of hydrogen and carbon oxide in synthesis of methanol, liquid hydrocarbons and higher alcohols [3]. Taking all these uses of hydrogen in account, some methods for commercial production of hydrogen have been proposed having their own advantages and disadvantages
