Malmberg is one of the development partners when the Öresundskraft evaluates the storage of surplus heat from the Filborna plant by heating the bedrock with 100-degree water. 900,000 SEK has been granted in support of the Swedish Energy Agency to develop this new heat storage technology in bedrock.
The basic idea is to warm up the bedrock with excess heat from Filborna plant during periods when excess energy is available, which creates advantages as power equalization in the district heating network in case of increased power demand and more efficient electricity generation. Seasonal heat in the bedrock is nothing new, but so far it has only taken place in solid ground called crystalline bedrock. The Scania northwest bedrock, on the other hand, is sedimentary, that is, old seabed.
The samples will take place next to the Filborna plant in Helsingborg and are expected to be completed in spring 2019. Öresundskraft Kraft & Värme is the project's head developer.
Malmberg is responsible for the development, manufacture and installation of borehole heat exchangers. LKAB Wassara is responsible for drilling technology development.
The project is very exciting and we see a future export opportunity if technology proves to be effective, as large parts of Europe have the same bedrock as in Helsingborg, "says Jon Svärd, from Malmberg Geothermal energy.
Fully expanded, a Helsingborg storage could store 50 GWh of heat, corresponding to the annual need for around 2500 villas.
