Nordic duo will build biogas liquefication plant in Gothenburg for bunkering

Liquefied biogas will be produced to make marine fuels for bunkering of vessels calling at the Swedish Port of Gothenburg, Nordion Energi said.

Swedish energy infrastructure firm Nordion Energi and Finnish biogas supplier ST1 will build a biogas liquefaction plant connected directly to a gas network in western Sweden.

The plant will be capable of liquefying up to 250 gigawatt hours (GWh)/year of biogas.

The biogas has to pass through one crucial step on its way to becoming a bunker fuel. It needs to be upgraded to so-called green gas by removing CO2 prior to the gas going through a liquefaction plant to become liquefied biomethane (LBM).

Nordion Energi and ST1 will store the LBM in a temporary storage tank in the Port of Gothenburg. It will then be supplied directly to ships through a pipeline or by truck.

The plant is scheduled to become operational by 2026.

LBM can function as a drop-in fuel in LNG, similar to the way biofuels can be blended with MGO or VLSFO. This means that vessels capable of running on LNG will not need modifications to run on pure LBM or LBM-LNG blends.
