Long term thermal energy storage with stable supercooled sodium acetate trihydrate
This principle makes long term thermal energy storage possible by letting the melted salt hydrate remain in supercooled state at ambient temperature in the storage period. Once the heat is needed the solidification of the supercooled solution is triggered and the latent heat of fusion is released as it crystalizes.

Hydrogen storage
Chemical storage could offer high storage performance due to the high storage densities. For example, supercritical hydrogen at 30 °C and 500 bar only has a density of 15.0 mol/L while methanol has a hydrogen density of 49.5 mol H 2 /L methanol and saturated dimethyl ether at 30 °C and 7 bar has a density of 42.1 mol H 2 /L dimethyl ether.

However, as physical thermal storage systems (sensible heat or phase change) progressively lose thermal energy [6], they are not suitable for long-term storage [16]. The relevance of storage systems based on sorption phenomena thus lies in their high energy density and their negligible heat loss and the repetitiveness of storage operations
