Methane production from biomass and green electricity
Interlinkage of the power and gas grids is planned to make electricity supply sustainable and robust in the future.
DemoSNG pilot plant constructed by the KIT, will be used in Sweden for the reliable and efficient production of methane from biomass-based carbon dioxide and variable amounts of hydrogen from green power, according to the institutes.
From the products of a biomass gasification plant, the DemoSNG pilot plant directly produces methane and water by means of a nickel catalyst. If green power is available, it is used for electrolysis and the production of additional hydrogen. Then, the volume flow in the plant can be doubled, utilization of carbon from biomass will increase to nearly 100%, and a large amount of usable waste heat will be produced by the catalyst.
