Scandinavian Biogas expands largest Bio-LNG plant in northern Europe

Swedish biogas producer Scandinavian Biogas invests $32 million in the expansion of the Gladö Kvarn plant to meet the demand for Bio-LNG.

The Gladö Kvarn plant produces liquefied biogas (Bio-LNG) in Södertörn, just south of Stockholm. Its expansion is to wrap up in the second half of 2023. The plant will produce 220 GWh of Bio-LNG per year, making it the largest of its kind in northern Europe. Notably, the former largest plant is Norwegian Skogn, also owned by Scandinavian Biogas.

Scandinavian Biogas will invest 300 million SEK ($32 million) in the plant. The plant will then liquefy both the biogas from Gladö Kvarn and the biogas from the production plant in Henriksdal in Stockholm.

The advantage of the gas liquid is that it only uses one-sixth as much tank volume compared to compressed gas. Thus, logistics and use become significantly more cost-effective, which makes it possible to sell the product throughout Europe.

In the project, Scandinavian Biogas collaborates with Gasnätet Stockholm regarding gas infrastructure. It also collaborates with Stockholm Water and Waste at Henriksdal in Stockholm. Air Liquide supplies the equipment for liquefying the biogas.

The plant is built with proven technology but is the first to be delivered in this size, the company says.

Swedish environmental agency’s program Klimatklivet granted investment support of SEK 135 million ($14 million) to the project. This is because it provides a large reduction in carbon dioxide emissions by replacing fossil fuels.
