    What this call funds

    This call funds pilot projects that make AI data centres more energy efficient and sustainable, covering better chip cooling, next-generation backup power systems, and smarter data centre-wide energy management. It also funds one open demonstration site that will bring together and showcase the results from the other funded projects as a European reference site. The goal is to cut cooling and power costs, reuse waste heat, and support Europe's technological independence in AI infrastructure.
