In the United States (US), Air Liquide, a world leader in gases, technologies, and services for industry and health, has certified its first Waga Energy cryogenic distillation module after acceptance testing was completed in January 2023. The company has ordered an additional two units from France-headed Waga Energy SA.
Waga Energy supplied the module for Air Liquide’s renewable natural gas (RNG) plant at the Mallard Ridge landfill in Delavan, Wisconsin (WI) where it has been in operation since March 2022.
Waga Energy’s patented cryogenic distillation module separates the methane from the nitrogen and oxygen gases found in landfill gas (LFG).
At the Mallard Ridge RNG plant, the module is implemented with an Air Liquide membrane filtration system. The RNG is injected into the local gas grid.
Air Liquide is a global leader in the gas industry, so we are obviously thrilled to have lived up to their expectations. This latest project confirms Air Liquide’s continued confidence in Waga Energy and will strengthen the bond that has existed between the two companies since Waga Energy was founded in 2015. Not only is Air Liquide our partner and biggest shareholder, but it is also a constant source of inspiration for us at Waga Energy, said Guénaël Prince, CEO of Waga Energy Inc.
First of three orders
The cryogenic module delivered to Mallard Ridge is the first of three Air Liquide has ordered from Waga Energy for its RNG plants in the US.
The other two modules are currently being installed at the Winnebago landfill in Rockford, Illinois (IL), where Air Liquide is building its largest RNG plant in the world to date, with an annual production capacity of 380 GWh.
In early April 2023, Waga Energy delivered from France the remaining two cryogenic distillation columns to Air Liquide at the Winnebago landfill. There, they will be assembled with several other pieces of equipment on skids manufactured by Waga Energy in Canada.
The completed cryogenic distillation modules will then be coupled with membrane filtration equipment manufactured by Air Liquide to form a large-capacity biomethane production unit.
