GoBiGas meets the growing need for biogas
Göteborg Energi bets big on biogas – one of the most important renewable fuels of the future. A great advantage with biogas is that the distribution can take place via the existing gas grid. Long term, biogas will be the road forward – the road initially paved by natural gas.
GoBiGas (Gothenburg Biomass Gasification Project) is a major Göteborg Energi project set out to build a plant to produce biogas via the gasification of biofuel and waste from forestry. When the plant is at optimal production, it will deliver in upwards of 800 - 1 000 GWh, which corresponds to fuel provision for between 80 000 - 100 000 cars.
Demonstration of gasification on a commercial scale
The aim of the GoBiGas-project is two-fold:
Phase 1 of the project is partly being funded through a grant from the Energy Agency in the amount of 222 million SEK. While the GoBiGas project continues, so does the research and development of a smaller gasification plant at Sweden’s Chalmers University of Technology.
The forest’s raw materials become biogas
At GoBiGas, biogas is extracted via thermal gasification of the raw materials of the forest, such as branches, stumps and forest residue. Biofuel is transformed into a combustible gas, syngas, which is purified and upgraded to a biogas, with a quality that is comparable to natural gas. This means that both gas types can be mixed in the same gas grid. Since biogas is produced from renewable sources, it does not contribute to an increase in the emissions of carbon dioxide.
Delivery to transport vehicles and industry
The distribution of biogas from GoBiGas will take place via the existing gas grid. Today, biogas is used primarily as transportation fuel, but it can even be used for heat generation and various industry processes. The demand is increasing quickly as new uses for it are established.
