The promise of seasonal storage
Seasonal storage is a form of storage typically accommodating yearly cycles in electricity demand and VRES generation. It stores energy during one seasonal condition (summer or winter) and discharges the stored energy in the other seasonal condition, depending on the load demand. Seasonal storage is, therefore, closely related to seasonal

Aqueous sodium hydroxide seasonal thermal energy storage
Seasonal storage of sensible thermal energy in materials is a challenge in respect to thermal loss corresponding to low volumetric energy density. In a process involving absorption and desorption lower heat losses and higher energy densities can be reached. The working pair sodium hydroxide (NaOH) and water can be employed to this purpose.
Seasonal pit heat storage: Cost benchmark of 30 EUR/m³
Seasonal heat storage is a very cost-effective way to make use of surplus electric power generated by wind farms in Denmark. "Wind energy has already contributed up to 40 % to electricity generation in a year and we want to combine this rich intermittent energy source with seasonal storage via heat pumps," Nielsen said.
