Biogas upgrading for vehicle fuel
First membrane biogas upgrading plant in Sweden
The biogas upgrading plant of Vårgårda-Herrljunga Biogas AB has chosen high selective membranes as biogas upgrading technology for their project. In a market where pressure water scrubbing technology is dominant, Vårgårda-Herrljunga Biogas is the first biogas upgrading plant in Sweden to use this membrane technology. Vårgårda-Herrljunga Biogas sees advantages with membrane technology through reduced maintenance and reduced energy costs when compared with alternative technologies available in the market.
VH Biogas AB is initiated by farmers in the area of Vårgårda and Herrljunga. These farmers had the idea to utilize the potential of the manure from animal waste and extract the biogas from it. through co-digestion of different types of manure is possible to also mix in other organic residues from agricultural and industrial production. When upgrading the biogas, a very high proportion of methane becomes available and can be utilized. This process reduces emissions of methane to nature, which is an important part of VH biogas’ environmental policy.
The municipalities of Vårgårda and Herrljunga showed early interest and support for this project and collaboration. The upgraded biogas will be made availible at the current filling station for cars and buses in Vårgårda where a number of busses and municipality’s cars already run on the environmentally friendly vehicle gas. The gas at the local filling station consists of 100% biogas from VHbiogas production facility. The remaining gas is distributed by Fordonsgas AB to other filling stations.
Location: Vårgårda and Herrljunga, Sweden
Biogas Inlet: 500 Nm³
Biogas Source: Agricultural waste – Co-digestion
Application: Vehicle fuel
Learn more about the project
VH Biogas has been producing biogas to use as vehicle fuel since 2014. Over 2 million m³ of gas was upgraded to vehicle fuel wich is the equivalent to roughly 2 million liters of diesel and are delivered annually through a gas pipeline to a petrol station in Vårgårda. From there, the surplus of the gas is distributed to other filling stations in western Sweden. The plant annually processes about 75,000 tonnes of substrate that is digested and delivered as biofertilizer to farms in the immediate area. The substrate consists mainly of manure. Slaughter residues, food residues, food waste and more also make up a significant proportion.
