In Sweden, St1 has made an investment decision to construct a biogas upgrading and liquefaction refinery in Sobacken, Borås. A prerequisite for the biorefinery investment decision is the long-term off-take contract to buy raw biogas, which St1 has signed with Borås Energi och Miljö. With the agreement, also the two public gas filling stations of Borås Energi and Miljö in Åhaga and Hulta will be transferred to St1. St1 will continue expanding its biogas filling network in the Nordics to distribute this new liquid biogas production.
St1 will start the construction work in the autumn and the biorefinery is expected to commence its operations at the end of 2023. St1 has signed an agreement with Wärtsilä Gas Solutions to supply the biogas upgrading and liquefaction facilities. The project has been granted support from Klimatklivet – a Swedish investment support program targeting projects reducing climate impact.
St1 and Borås Energi och Miljö together create a strong value chain in renewable biofuels, both focusing in their own areas of expertise. St1 will upgrade and liquefy the raw biogas Borås Energi and Miljö produces from food waste and sewage sludge, and then sell it in its developing distribution network.
