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.

Europe's rapid solar expansion is pushing power grids to their limits. Grid operators across the continent are now turning to co-located solar-plus-storage systems to stabilize networks, absorb excess generation and unlock new connection capacity. These projects mark a shift from asset-centric storage design to grid-integrated operation and market-based procurement. This session highlights recent 2026 initiatives that show how integrated solar-plus-storage assets can reinforce the grid by providing congestion relief, voltage and inertia support and firm capacity, thereby enabling higher renewable penetration and broader market participation. Speakers will share lessons from real-world projects demonstrating how close coordination between grid operators, developers and flexibility providers transforms solar-plus-storage systems from a balancing resource into essential grid infrastructure.
