Air Liquide has commenced construction of two new RNG production units located in Center Township, Pennsylvania, and Holland Township, Michigan, treating waste sourced from dairy farms, according to a press release.
The 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, promoting circular economy in waste management. Using Air Liquide’s proprietary gas separation membrane technology, the biogas will then be purified into RNG and injected into the natural gas grid.
Air Liquide 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 biomethane operational production units in the world for a yearly production capacity of about 1.8 TWh, according to the news release.
