Air Liquide acquires renewable natural gas plant


Air Liquide has purchased in the U.S. the renewable natural gas assets of Georecover – Live Oak, LLC, a subsidiary of Jacoby Energy Development, Inc., a Georgia-based company which recovers and processes landfill exhaust gas into renewable natural gas, sometimes referred to as biomethane.

Included in the sale was the company’s landfill gas processing facility in Conley, Ga., near Atlanta, U.S. The Conley facility, which uses Air Liquide’s proprietary MEDAL membrane technology, processes all of the landfill gas from the adjacent Live Oak landfill, generating up to 1,500 MWh of renewable natural gas daily to be transported via pipeline. This natural gas can be used as a feedstock for renewable hydrogen, renewable compressed or liquefied natural gas or to generate renewable electricity.

The acquisition demonstrates the Air Liquide Group’s strategy of bringing sustainable, clean energy solutions to customers worldwide.
