Steam methane reforming overview sometimes referred to as steam methane reforming (smr), this process involves the heating of methane (ch 4) with steam, in the presence of a catalyst, to create hydrogen (h 2) and carbon oxide byproductsafter the initial reforming reaction, the steam undergoes a water-gas shift reaction, which converts carbon. Becausethe process of steam reforming of methane is the reforming process that leads to obtaining syngas with the highest h2/co ratio, this type of reforming process is considered ideal to obtain a hydrogen gas flow of figure 2 h. In recent years, hydrogen (h 2) has gained much research emphasis as an energy carrier due to its environmental friendliness and wide range of energy applications  approximately 95% of the hydrogen in the united states is generated via methane steam reforming, being utilized predominantly for petroleum refining and the production of. Hydrogen production hydrogen is an energy carrier, not an energy source—hydrogen stores and delivers energy in a usable form, but process, called steam methane reforming, accounts for about 95% of the hydrogen used today in the us another method, called partial oxidation.
