A fuel cell-based CHP plant at the Vaasa Housing Fair, developed by Wärtsilä, has been officially inaugurated.

Based on planar solid oxide fuel cell (SOFC) technology, it is the first of its kind in the world and is fuelled by methane gas originating from a nearby landfill site.

The unit for the fair site is Wärtsilä’s first field application of the technology and during the initial phase it will produce approximately 20 kWe and 14 kWth – 17 kWth. Electricity and heating from the device will be used within the fairground area. In addition to the fuel cells, on-site power and heat are also produced by micro turbines and from low-temperature heat collected from the seabed using a geothermal heating pump.

Wärtsilä is responsible for both the delivery of the fuel cell plant, as well as the building development and project-time financing for the New Energy power plant building at the fair site. Wärtsilä’s partners in the project include Sarlin Oy, Mateve Oy, Suomen Lämpöpumpputekniikka Oy, Sonera, plus the City of Vaasa, Vaasan Sähköverkko, Vaasan Sähkö and Vaasan Vesi.

‘The development of environmentally friendlier, cleaner, and more sustainable energy production technologies is an essential element of Wärtsilä’s strategy’, says Juha Kytölä, managing director of Wärtsilä Finland Oy.
