In the current NEFI project CASCADE, the geothermal potential in Steyr, Gmunden and St. Martin im Mühlkreis in the industrial, commercial and residential sectors will be investigated over the next two years until the end of 2025 using the innovative method of gradual heat utilization. This technology makes it possible to use the thermal energy generated not just once, but in successive stages or "cascades" for various purposes, from heat for industry to heating buildings, with decreasing temperatures.
