Air Liquide builds two RNG facilities in US

Air Liquide on April 10 announced the expansion of its capacities in biomethane, also known as renewable natural gas (RNG), in the US with the construction of two new production units.

These units, located in Center Township, Pennsylvania, and Holland Township, Michigan, will treat waste sourced from dairy farms. Following a circular economy approach, these units will contribute to the emergence of a low-carbon society.

These production units will produce biogas from manure feedstock in an anaerobic digester for a total production capacity of 74 GWh, and return the digested waste for the farms’ need. Using Air Liquide’s gas separation membrane technology, the biogas will then be purified into RNG and injected into the natural gas grid.

“These investments in the US are in line with the priorities of our strategic plan Adavnce for 2025, which inseparably links growth and a sustainable future,” said Armelle Levieux, vice president of innovation. “Biomethane is part of the portfolio of solutions developed by Air Liquide to support the decarbonization of its customers in the industry and transport sectors.”

Air Liquide currently has 26 biomethane operational production units in the world for a yearly production capacity of about 1.8 TWh.
