Hydrogen production from biogas by steam methane reforming process

Abstract

In recent years, interest in hydrogen, especially green hydrogen, has been increasing in order to achieve carbon neutrality by 2050. In this paper, I describe various methods of hydrogen production from hydrocarbon raw materials, including synthetic gas production and purification from synthetic gas to high-purity hydrogen, the history of the development of hydrogen production equipment in the Daigas Group, and compact hydrogen production equipment "HYSERVE". Then I introduce same cases of hydrogen production from biogas by steam reforming implemented in Japan. Finally, I describe a comparison of CO2 emissions during hydrogen production using steam reformers and water electrolyzers during the transition period to a low-carbon and decarbonized society.
