[Horizon Europe - DIGITAL] CL4-2027-04 Energy-efficient AI Data Centres
This is a demonstration-heavy, industrially oriented grant for mature technologies that can materially reduce the energy and environmental impact of AI data centres. The Commission wants practical pilots, not conceptual studies: cooling, power backup, AI-aware operations, waste-heat reuse and energy-system integration all need to be shown in credible real-world settings. The most competitive bids will probably present a full-stack story: chip/module thermal management + data-centre operations optimisation + energy/waste-heat integration + validated industrial use cases. A good proposal should…

Who it suits
What the EU wants funded The call is built around four outcome areas: Better cooling for high-power AI chips — for example direct on-chip cooling, advanced thermal interface materials and multi-scale thermal management, aiming to reduce cooling energy and avoid thermal throttling. Novel backup powe…
