The facility has the capacity to produce around 120 gigawatt hours/year (GWh) of liquefied biogas, making it one of the largest of its kind in the country, Gasum said.

The plant will use approximately 400,000 mt/year of manure and other agricultural waste as feedstock to produce biogas. The gas must then be upgraded into biomethane by removing CO2, before it can be liquefied and used as bunker fuel.

Both the upgrading and liquefaction processes will take place on-site at the integrated facility. The liquefied biomethane (LBM) will be delivered by truck to customers in shipping and other sectors, the company said.

LBM consists of approximately 99.8% methane. This composition allows it to be used as a drop-in fuel for LNG, similar to how biofuels are blended with marine gas oil (MGO) or very low sulphur fuel oil (VLSFO).

LNG-capable vessels can operate on pure LBM or LBM-LNG blends without requiring modifications.

Gasum already supplies LBM for marine bunkering across Nordic ports. It recently announced that one of its dual-fuel LNG bunker vessels, Kairos, will be powered by LBM to generate overcompliance under its FuelEU Maritime pooling scheme.

The company has also set an internal target to produce around 7 terawatt hours/year (TWh) of liquefied biomethane by 2027 to meet demand from shipping and other sectors.
