Gasum supplying bio-LNG to Equinor’s PSV in Norwegian port

Finnish state-owned energy company Gasum has started supplying bio-LNG using the mass balancing concept to Norwegian energy firm Equinor’s chartered platform supply vessel (PSV), Island Crusader, in the Norwegian port of Dusavik.

Mass balancing is a method used to track sustainable feedstocks in the supply chain, enabling the blending of renewable and non-renewable materials while keeping an accurate record of each. By quantifying the amount of sustainable feedstock used in production, distribution, blending and bunkering, mass balancing ensures that the claimed sustainability of the blended fuel matches the actual amount of sustainable feedstock used.

The Island Crusader, a ship designed to transport supplies and equipment to and from offshore oil and gas platforms, was bunkered with ISCC-EU certified mass-balanced bio-LNG by Gasum for the first time in the Port of Dusavik in July.

Bio-LNG is produced from biogas generated through the anaerobic digestion of waste feedstocks such as bio-waste, sewage sludge, manure, and other industrial and agricultural side streams. Dual-fuel LNG vessels can run on bio-LNG without requiring any modification.

Gasum will continue supplying the Island Crusader with 2–3 truckloads of bio-LNG approximately every other week, with each truckload containing about 22 mt of bio-LNG. The two companies have not disclosed the tenure of this supply agreement.
