ENERGY FROM WASTE Demo gasification project under way
Metso is to supply a gasi- fier in an order worth €30M euros to Göteborg Energi AB´s GoBiGas20MW project. The gasification demonstration plant will be operational in 2013.
The GoBiGas20MW project will produce biogas by gasifi- cation of biofuels and waste from forestry. The demo plant is scheduled to be built in two stages to demonstrate the tech-

nology of the green gas con- cept. Ownership and respon- sibility for operating the plant will be transferred to GoBiGas AB, mainly owned by Göteborg Energi AB.
Metso will be involved in the first stage when the gasification plant is built on the existing premises of Rya Värmecentral in Gothenburg, Sweden, during 2011-2013. On a commercial scale, the final plant will have a capacity of around 100MW biogas with an operating period of 8,000 hours/year. The Metso gasification solu- tion is based on new licensed technology for indirect gasifi- cation developed by Austrian company REPOTEC. With for- est residue and wood pellets as
main fuels, the gasification sys- tem, together with the metha- nation and up-grading system, will produce high-calorific gas, biomethane, for distribution in the existing gas grid.
“We see a huge market poten-
tial for biogas in replacing fossil alternatives and our mission is to show that gasification can play an important role in biogas supply,” says Åsa Burman, CEO of the GoBiGas project. “The quality of the gasification is essential for the success of the project. With the equipment from Metso together with the methanation and gas-upgrading technology, we are able to pro- ceed to the next step.”
