The Finnish Broadcasting Company YLE published a nice news story about the need for energy storages. The article is called “New ways are being developed for the storage of renewable energy - A company from Tampere aims to go global with a method in which the energy of surplus electricity is stored in sand”.

The interview is set in the Pilot Heat Storage in Hiedanranta, Tampere, where it is used to feed heat to local buildings. CTO Markku Ylönen explains in the article, in national television and in local radio the operation of our Heat Storage and our vision for future. The Heat Storage allows the upscaling of renewables to much higher degrees than otherwise possible.
