Production of renewable gas from waste wood

KIT's researchers succeeded in producing renewable methane from a biomass-based synthesis gas mixture in their pilot plant for honeycomb methanation. The quality of this synthetic natural gas (SNG) is comparable to that of ...

Biogas does not need subsidies

Subsidizing the combustion of biogas is expensive and prevents its use in a more effective way, according to Ghent University (Belgium) scientists in the leading journal Energy & Environmental Sciences. They propose using ...
