Researchers from the Karlsruhe Institute of Technology (KIT) in German have demonstrated a novel method of converting the outputs of biogas facilities into methane. The new type of methanation plant can fit inside a standard shipping container, and could be combined with renewable energy production as a means of storing the excess and intermittent supply that is inherent to wind and solar power.
“As conventional methanation processes reach their limits at this point, we have developed a new reactor concept,” said Siegfried Bajohr, the leader of the new project, in a press release. The concept takes the products of biomass gasification—hydrogen, carbon dioxide, and carbon monoxide—and uses a nickel catalyst to produce methane and water. The catalysis is done in a “honeycomb catalyst carrier,” already used as catalytic converters in cars, which are “characterized by a high thermal conductivity and mechanical robustness.”
When connected to the electricity grid or production…
