PUSH – CCC
Pushing the limit of large-scale energy storage: Optimized Combined Cycles CAES
Time Period: October 2023 – September 2027
EU Contribution: 3.426.308,75€
Project description
The PUSH-CCC project aims to tackle key challenges of compressed air energy storage (CAES) technology by enhancing its scalability, efficiency, energy density and commercial viability in Europe. Researchers will develop an advanced CAES concept up to technology readiness level (TRL) 4, leveraging AI-optimized heat pump cycles, efficient heat storage technology and a disruptive hierarchical control system. Furthermore, the proposed technology will capture CO2 from the atmosphere. Project activities also involve the construction of an experimental cavern lab in the Canary Islands, which will lead to the first isobaric adiabatic CAES system at TRL4 in Europe. Project outcomes will contribute to accelerating renewable energy integration into the grid.
Our contribution
Investigation of the design and optimal sizing of heat exchangers for heat recovery from compressed air in compressor intercoolers in the adiabatic CAES plant. Investigation of different types of heat transfer fluids (including nitrate salts, carbonate salts and pressurized water) for diverse temperature levels and optimization of the thermal energy storage system technology and configuration.
