Air Liquide and Puregas Solutions signed an agreement to access their respective biogas upgrading technologies.

This collaboration allows the two experts to provide biogas upgrading solutions that meet customers’ needs and projects’ characteristics.

The agreement uses the synergies of Air Liquide and Puregas Solutions, and is complementary to the offers of both companies in equipment sales, maintenance and service.

Air Liquide and Puregas commissioned a first joint membrane upgrading unit in Rybjerg, in northern Denmark, with a capacity of 900m3 per hour of biogas from agricultural waste.

The biomethane upgraded thanks to this technology can be notably used as fuel for vehicles (Bio-NGV). Air Liquide has developed technologies and expertise that span the entire biomethane value chain.

Through its subsidiary FordonGas, the group owns a biomethane liquefier and a network of 48 natural biogas refuelling stations for Bio-NGV’s covering south western Sweden. The collaboration with Puregas Solutions also allows Air Liquide to continue its biogas development in the Nordic countries.
