Wartsila to deliver equipment for Swedish bioLNG project

Wartsila, a technology group, has been contracted by Finland’s Gasum to provide equipment and expertise for a bioLNG project in Sweden, it said on June 13.

The project involves upgrading biogas from agricultural waste and converting it into bioLNG. The installation will be located near Gotene, Sweden, and will have a production capacity of 25 metric tons/day of bioLNG.

The Wartsila solution involves purifying the biogas by removing hydrogen sulphide, carbon dioxide, and water vapour before liquefying it at -160 °C. The resulting bioLNG has similar properties and calorific value to fossil LNG, making it a sustainable and environmentally friendly fuel, Wartsila said.

The Gotene biogas plant project is the first of five large biogas plant projects planned by Gasum in Sweden in the coming years.

Wartsila will deliver, install, and commission the upgrading and liquefaction equipment, with the delivery scheduled for August 2024. The facility is expected to be fully operational at the beginning of 2025.
