Klemens Kaar presents innovative compressed air energy storage (CAES) technology to accelerate de-carbonization and enhance grid security

Klemens Kaar, Project Development Director for Corre Energy in Germany, discusses compressed air energy storage (CAES) technology. Corre Energy is a European company focused on innovative long-duration energy storage projects to enhance grid security and accelerate decarbonization. CAES stores excess renewable energy by compressing air into subsurface cabins and releases it during high demand via turbine expanders, generating electricity back into the grid. The process includes managing heat released during compression and addressing the cooling effect from decompression using hydrogen co-firing. CAES is positioned between pumped hydro and battery systems in terms of capacity and duration flexibility. Currently, Corre Energy develops projects in Holland, Denmark, and Germany—the latter aiming to establish a large-scale facility by 2030 near Aarhus due to its strategic location amidst rising power consumption areas. The German project features multiple phases with initial capacities of 200 MW for compression and 300 MW for generation; ultimately doubling these figures as part of future expansions. Key considerations include leveraging existing salt caverns for storage while integrating closely with local infrastructure like the hydrogen backbone network Get H2 Startnet—highlighting significant potential across Northern Europe including regions like France, Spain, Portugal, Romania's northern Alps area.

Off-grid solar systems are often the least expensive option for rural electrification. Solar home systems can power individual households, while mini-grids can supply entire villages. Each comes with its own advantages, disadvantages, and challenges. The aim of this session is to explore challenges as well as success stories. It takes well-functioning components such as battery systems, charge management and inverters to make projects successful. Proper system sizing, maintenance and repair management, as well as a robust financial concept are also necessary. If one of these elements is missing, the electrification will not be sustainable. This session will focus on the aspects mentioned above. The speakers will present successful and unsuccessful approaches and discuss what can be learned from them.
