Tackling key challenges of compressed air energy storage technology

The EU-funded 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-optimised 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.
