Emerald Horizon AG has announced new study results showing that molten salt storage can use latent heat from solidification to increase energy output. - Researchers from TU Graz and Emerald Horizon AG found the storage system can deliver around 6% more energy from the same volume, with the study published on 13 October in the journal Energies.
- The results apply to CALstore, the thermal storage unit in DUALstorePLUS; the company says the thermal module for temperatures up to 550°C is scheduled for 2028, while the battery part is already available. The study was funded by FFG as part of the CALstore project.
