Flexible Solar power generation with Compressed Air Energy Storage

ASTERIx-CAESar

ASTERIx-CAESar is a Horizon Europe funded project focusing on the development of a novel high-efficiency solar thermal power plant concept with an integrated electricity storage solution. ​

The project combines air-based central receiver Concentrated Solar Power and Compressed Air Energy Storage to maximize conversion efficiency and power grid energy management.​

Project Concept

Higher shares of variable output renewables in the energy system (PV and wind energy)
Adiabatic CAES with round trip efficiency up to 65-75 % and economical artificial above-the-ground storage system
Disruptive and highly efficient Open Volumetric Air Receiver (OVAR)
Packed-bed thermocline and efficient air-air low and high-temperature heat exchangers
Competitive desalination process composed by Reverse Osmosis (RO) + Air-Water pressure exchanger (ERD) + Thermal Vapor Compression (TVC)

Main impacts

Higher share of variable output renewables
Higher efficiency of CSP plants
Reduced operation and maintenance costs of CSP plants
Achieving EU targets for Global Leadership in CSP
