Gasum ramp up Swedish bio-LNG production capacity with new plant

Finnish energy firm Gasum expects its upcoming biogas plant in Götene will have a bio-LNG producing capacity of 25 mt/day once operational.

Engine maker Wärtsilä will deliver “know-how and equipment” for upgrading and liquefying biogas from agricultural waste into high-quality bioLNG for the project.

BioLNG is made by “purifying biogas by removing hydrogen sulphide (H2S), carbon dioxide (CO2) and water vapour” and then its liquefied at -160 °C.

“It has the same calorific value and other properties making it usable as an environmentally sustainable fuel fully compatible with fossil LNG,” Wärtsilä claims.

Wärtsilä has planned delivery of the equipment for August 2024, and expects the plant to be fully operational at the beginning of 2025.

However, neither party specified if any part of bioLNG produced in the Götene facility will be used as a marine fuel.

Götene biogas plant project is the first of “five large biogas plant projects in Sweden” being developed by Gasum, Eero Lallukka, the company’s senior manager, says.
