E.On has announced plans to build a €5.4 million deep geothermal power plant in Sweden to feed Malmö’s district heating system.
The company is planning to drill 5-7 km-deep boreholes into the ground, where the expected 160°C temperatures will be sufficient to feed directly into the district heating network.
The pilot project will be one of Europe’s first geothermal power plants to extract geothermal energy from depths of several kilometers on an industrial scale, E.On said.
E.On is currently investigating the geological conditions through test boreholes. If the project remains on schedule, the plant will supply renewable and resource efficient heat to district heating customers from 2022, E.On said.
It is planning to build five geothermal power plants in Malmö by 2028, each with an installed capacity of 50 MWth. One of its partners in the project is St1, an energy company with experience of deep geothermal drilling in Espoo, Finland.
Other partners include the Swedish Energy Agency, the Swedish Geological Survey, the City of Malmö, and the University of Uppsala.
The Swedish Energy Agency will support the pilot project with €2.1 million of funding. The project is expected to go on stream this year.
“E.On’s goal is to supply Swedish customers with 100 per cent renewable and recovered energy,” said Marc Hoffmann, CEO of E.On Sweden. “With deep geothermal energy, we’re tapping into a new energy source that can ensure renewable production in the long term. Deep geothermal energy is resource-efficient, emission free, noise-free and space saving, making it one of the best solutions for urban energy systems of the future.”
