ENEA examines molten-salt storage for energy systems
ENEA announced on 15 October the SALTOpower study, which examines thermal storage using molten nitrate salts in multifunctional energy hubs to support flexible use of renewable generation. The agency also pointed to the availability of steel and nitrate salts in Europe.

Published: · Updated:
ENEA cited an estimate that the European grid may need 200–400 GWh of storage by 2030 and said installed battery capacity is about 77 GWh. These are Europe-wide source figures, not Italian installed salt-storage capacity or measured SALTOpower performance.

SALTOpower and European storage needs
The study examines thermal storage with molten nitrate salts; European storage needs are estimated at 200–400 GWh by 2030, against about 77 GWh of installed battery capacity.
Methodology
Values are a Europe-wide source estimate and reported installed capacity, not project measurements.
