Start-up of new LCBG station in Fredriksstad

November 2021

Last week, it was finally time to start up our newly built LCBG facility for Fredrikstad municipality, which will supply the municipality’s laundry with biogas, offer a refueling ramp for about 30 garbage trucks and a public dispenser for vehicle gas.

Although all consumers at this plant use biogas in gaseous form, this station is not fed with mobile gas storage with compressed biogas but with the help of liquefied gas at minus 160 degrees which is then evaporated to the correct pressure as needed in the plant.

Before we can fill the cryogenic tank with liquid biogas (methane gas), we cool down the entire system with liquid nitrogen gas for control and to avoid releasing methane gas. Afterwards, it was time to empty the now cooled tank of the harmless nitrogen gas before filling with ice-cold biogas; something that made our automation engineer Jonas Thebrin Larsson long for wonderful cold ski days in the mountains when the fog suddenly hits…
