Biomass Gasification Vaskiluodon Voima to build world’s largest Biomass Gasification Plant

| Editor: Marcel Dröttboom

Vaskiluodon Voima Oy will build a 140 megawatt biomass gasification plant in Vaasa, Finland. The investment enables the replacement of coal with domestic wood-based renewable fuels. The plant, to be supplied by Metso, will be constructed as part of the existing coal-fired power plant.

Vaasa, Finland – Vaskiluodon Voima’s total investment is about EUR 40 million, over half of which is attributable to Metso’s delivery. The bio-gasification plant is scheduled for commissioning in December 2012. Metso’s full-scope solution includes fuel handling, a drying plant and a circulating fluidized bed gasifier, modification work on the existing coal boiler, and automation and IT systems.

The bio-gasification plant will be constructed as part of the existing coal-fired power plant. The plant will be fueled primarily with wood-based biomasses, particularly forest residue, and the produced gas will be combusted along with coal in the coal boiler. The delivery includes the drying plant where biomass will be dried to the proper level for gasification. As a result of the new solution, close to 25 to 40 per cent of the coal can be replaced with renewable energy, which will reduce carbon dioxide emissions by about 230,000 tonnes per year. This is the first time in the world that biomass gasification is being adopted on such a large scale.

Vaskiluodon Voima Oy is a power and heat production company equally owned by EPV Energia Oy and Pohjolan Voima Oy. EPV Energia Oy is a Finnish company specializing in power and heat production and procurements, and its domicile is Vaasa, Finland. Pohjolan Voima Oy is a national energy company; its main products are power and heat.
