New Bio-LNG refueling station in Norrköping with a climate-smart solution for the boil-off

November 2022

Now it’s really full speed ahead… last week we commissioned the new LBG backup for Örebro municipality and already this week we are commissioning a new LBG filling station for Svensk Biogas in Norrköping Ingelsta. This will be the third filling station for liquid biogas (also known as Bio-LNG or LBG) that we build for Svensk Biogas after the stations in Mjölby and Mörtlösa and is located at Alfredsson Transport AB, which has long been at the forefront of climate-friendly transport. With the new filling station outside the door, Alfredssons can now refuel its fossil-free LBG trucks at home as well.

Liquid biogas is stored at -160 degrees in a cryogenic vacuum-insulated tank that can be compared to a giant thermos. It keeps the heat out brilliantly, but sooner or later some of the gas will still heat up and change from liquid to gaseous form (“boiling off”) where the gas expands by a factor of 600. Then the pressure in the cryogenic tank is gradually raised and in order to avoid the safety valve being activated, we can either cool down the biogas with liquid nitrogen gas (-190 degrees) or use the boil-off.
“When there is a need for compressed vehicle gas, we like to use the decoction to offer CBG refueling to avoid using nitrogen for cooling. However, since there was no need for CBG, together with the customer we came up with a climate-smart solution where we use the decoction to heat their properties and can thus greatly reduce nitrogen use as well as heating costs.” says Torbjörn Karlsson, Technical Manager at Processkontroll Green Technology.
