Air Liquide Expands Biomethane Capacities in the US

15.04.2024 - Air Liquide is to expand 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.

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’ needs. Using the company’s proprietary gas separation membrane technology, Air Liquide said, the biogas will then be purified into RNG and injected into the natural gas grid.

Armelle Levieux, member of Air Liquide’s executive committee and Vice President of Innovation, said: “With these two new biomethane production units, Air Liquide is reinforcing its presence in the US RNG production market. These investments in the US are in line with the priorities of our strategic plan ADVANCE for 2025, which inseparably links growth and a sustainable future. 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.”

According to Air Liquide, it has developed competencies throughout the whole biomethane value chain, starting with biogas production from waste, to its purification into biomethane to be injected into gas grids or compression/liquefaction with storage and transportation to customers. Air Liquide currently has 26 global biomethane operational production units with a yearly production capacity of about 1.8 TWh.
