German Utility Looks to Turn Excess Wind Into Clean Methane


German utility Uniper launched a pilot scheme at its Falkenhagen site on Wednesday to produce methane gas from wind power as the country seeks wider uses for renewable energy.

The Falkenhagen plant, set up five years ago in Germany’s wind-swept Brandenburg state, already produces green hydrogen by running wind power through water to split it into oxygen and hydrogen. Methane gas would provide a higher quality material with more diversified uses.

“This is an important step for a successful energy transition,” Uniper said in a statement after the company opened a new facility at the site for the scheme. “Green methane, in contrast to green hydrogen, can be used in a wider variety of ways.”

Germany is looking at new ways to use and store renewable energy at a number of power-to-gas sites as a boom in wind and solar power in the country has led to excess production. Billions of euros have also been spent building up a natural gas infrastructure, which the government wants to use to store carbon-free energy rather than retiring it once renewables largely replace coal, nuclear power and gas by the middle of the century under the government’s energy policy.

Under the two-year pilot scheme, the company will set out to produce green methane by using carbon dioxide from a bio-ethanol plant and mixing it with the hydrogen, creating a gas-like substance. If Uniper engineers can show the technology is viable, they hope that Germany can lead the way in providing the renewables sector with an entirely new raw material.
