How does molten salt energy storage compare to other
Cost-effectiveness: Thermal storage costs range from 15–25 EUR/kWh for molten salt, up to 33 times cheaper than lithium-ion batteries (833

But here''s the kicker: the cost of molten salt energy storage isn''t just about buying fancy salts and tanks. Let''s unpack the real price tag behind this sizzling-hot renewable energy solution.
Notably MIT published a prototype MSB with a cell cost of $9/kWh in 2024 vs $120/kWh for standard lithium-ion batteries. Market drivers include
Fact sheets created by the German Energy Storage Association,
Thermal energy storage is provided by direct storage of the HTF in a 2-tank system, and the design assumes dry cooling. The spreadsheet allows users to estimate the cost of different-size plants and
The global molten salt thermal energy storage market is
The LoCoMoSa project aims to develop and demonstrate a cost-effective thermal energy storage system with a medium to long storage period based on molten salt.
Molten salt proved thermal storage at scale, yet faces limits in efficiency, cost, and risk. Simpler industrial heat solutions are overtaking it.
Storage solutions will therefore play an increasingly central role in ensuring a reliable and efficient energy supply. Molten-salt circuits already have large
