SEAS-NVE is at the forefront of taking the green transition to new heights, by storing large amounts of energy in rock heated to 600 degrees.
The limit on how much non-controllable, renewable energy the current Danish energy network can manage is about to be reached. Over the next year, SEAS-NVE will, in collaboration with DTU Energy, Aarhus University Geoscience, Danish Energy Association, Energinet.dk and Rockwool, try to come up with an innovative solution to the problem by developing a high-temperature thermal storage solution, in which the energy is stored in rock heated up to 600 degrees with air from an electric fan heater. The ambition is to implement the solution on a large scale throughout Denmark at competitive prices, while addressing the challenge of saving large amounts of energy in a cheap and environmentally friendly manner.
In the first year of the pilot phase, the energy storage solution will be located at Risø DTU Campus. From 2019, it is planned to locate the storage solution in fields next to the Sorø Power Plant, during what we call the demonstration phase. It has not yet been planned where the "real", full scale storage shall be located, but it is expected to be in the Zealand region.
The storage solution consists of a pile of insulated rocks, which is heated to 600 degrees, powered by surplus electricity from wind turbines. After a few days, when the energy is again required, the heat is fed through a generator which generates electricity, and the residual heat is conducted to district heating.
The project is supported by EUDP
The project is supported with DKK 6 million from the Energy Technology Development and Demonstration Programme (EUDP), which is a public subsidy scheme. The scheme supports new technologies in the energy sector, which can help to meet Denmark's objectives in regards to energy and climate.
