SENS initiates feasibility study in the Värmlandsberg mine with water samples and ROV filming

17 November 2022, 15:30

Sustainable Energy Solutions Sweden Holding AB ("SENS" or the "Company") announces today that the Company has started the feasibility study in the Värmlandsberg mine. In order to verify the conditions for constructing a full-scale pumped-storage plant, SENS has now begun taking water samples and an initial underwater survey with a Remotely Operated Underwater Vehicle (ROV).

One of SENS's energy storage projects in an underground mine is the so-called Värmlandsberg mine. The mine is located approximately 15 km north of Filipstad in Värmland and is intended to function as a large-scale energy storage facility according to SENS’ energy storage concept. The mine has a depth of approx. 400 meters where iron ore mining has been carried out until 1980. The mine's properties and design have been analysed and identified as well suited for SENS's energy storage concept, where the mine's drop height and shaft will function as a transport shaft and reservoir for the water masses used to generate clean energy when there is demand in the grid. For more description of the concept, read more on SENS’ website.

As next step in the development of the project, SENS now announces that the work on feasibility studies has begun. The first part of the process includes activities in the form of water samples and filming with ROV to verify the water quality and the drawings of shafts and mining rooms in the mine, which in turn will be used as a basis for permit applications and technical feasibility studies. Once this is in place, the project will enter the next phase and technical design plans can be verified and concretized.

"For the Company, this is a very big step in our active work to take our PHS project to the next level and in this also demonstrate the Company's capabilities regarding conceptual solutions for long-term energy storage. At the same time, we are now seriously building a future energy cluster around Filipstad," says Henrik Boman, CEO of SENS.
