The Sun2Store project promotes the storage of electrical energy by means of heat pumps in molten salt tanks, and the subsequent delivery of this energy to the grid for more than 10 hours at an output of 100 MWe.
This grid-scale installation will be able to provide renewable energy during periods when there is no solar or wind resource available, thus contributing to the coupling between production and demand and consequently leading to a greater penetration of renewable energy sources in the generation mix.
