Hydrogen gas can also produce from water using the water electrolysis method which acting about 95% of the total quantity of hy-drogen produced [91]. A synthesis gas can also be created by reacting coal or biomass with high-temperature steam and oxygen in a pressurized gasifier. Currently, hydrogen production is responsible for putting about 830m tonnes of CO 2 into the atmosphere (Rozyyev et al., 2019).Although the main commercial route to hydrogen production in the steam-methane reforming process, hydrogen can be also produced via electrolysis, thermolysis, biomass gasification, bio-catalysis or fermentative routes (Shamsudin … On the other hand, the efficiency of the partial oxidation process of methane is recorded about 50% [54]. 1. Thermal processes for hydrogen production typically involve steam reforming, a high-temperature process in which steam reacts with a hydrocarbon fuel to produce hydrogen. 70-80.

Methane decomposition performs at similar energy efficiency to steam reforming and typically uses 10 times less electricity than an electrolyzer, and requires a fraction of the space/land. The steam reforming plant consists of four basic sections (Bressan et al., 2009): • The first is feedstock treatment where sulphur and other contaminants are removed. Both pathways have fundamental disadvantages, either in the level of emissions produced, the cost of production or the amount of energy needed being more than the output of the hydrogen generated. • CH4 + H2O = CO + 3H2 – steam reforming of methane • CO + H2O = CO2 + H2 – water gas shift reaction Hydrogen fuel cell • H2 + ½ O2 = H2O + electricity + heat N.B. Many hydrocarbon fuels can be reformed to produce hydrogen, including natural gas, diesel, renewable liquid fuels, gasified coal, or gasified biomass. As the chart illustrates, DRYREF technology significantly lowers the production costs of both conventional steam methane reforming (SMR) and SMR with a pre-reforming step (although these figures can vary slightly depending on utility costs). • The second is the steam methane reformer, which converts feedstock and steam to syngas (mainly hydrogen and carbon monoxide) at high temperature and moderate pressure. Depending on the technology and the fossil fuel used, blue hydrogen plants can capture 50–90 percent of CO 2 emissions, yielding approximately 2–5 kg CO 2 per kg H 2 produced.
