CEEGS researchers from the University of Seville and Converge! have published a paper on the “Assessment of carbon dioxide transcritical cycles for electrothermal energy storage with geological storage in salt cavities” in Applied Thermal Engineering (A.Carro, J.Carneiro, C.Ortiz, D.Behnous, J.A.Becerra, R.Chacartegui).
Highlights:
- Integration of CO2 geological storage in electrothermal energy storage system.
- Innovative analysis of the impact of salt cavity conditions on system behaviour.
- Round-trip efficiency can exceed 70% if all the stored thermal energy could be used.
- Adaptation of transcritical CO2 cycles and salt cavity scenario is feasible.
