Overview

The Horizon Europe funding opportunity HORIZON-CL5 focuses on thermal energy optimization and waste heat recovery in high-energy-demand IT rooms and small edge data centers in buildings. It is classified as an Innovation Action (IA) and falls under the broader European initiative to enhance energy efficiency and support a transition towards climate neutrality. Eligible applicants include organizations and consortia from EU Member States and Associated Countries. This includes research institutions, SMEs, large enterprises, public authorities, and non-profit organizations; however, entities from China are explicitly excluded from participation. The financial support is structured as a lump sum grant, with €5,250,000 available per project, and a total budget of €15,750,000 allocated to fund three projects in this topic area. A consortium of at least three legal entities from different Member States or Associated Countries is required for the submission of proposals, although the specific call does not explicitly confirm this requirement. The project's primary sectors include energy optimization, ICT, data centers, and building sustainability, with emphasis on cross-cutting technologies like artificial intelligence and advanced building management systems. The project aims to develop and demonstrate state-of-the-art approaches to managing thermal energy effectively, particularly in varying climatic conditions, thus addressing different geographic challenges in waste heat recovery. This ensures that solutions can be adapted for both cold and warm climate zones. The application process will be a single-stage submission, with the call opening on May 5, 2027, and closing on September 15, 2027. Proposals are expected to include practical solutions for thermal management and business cases for heat reuse that will contribute to the European climate goals and energy strategies. Success rates for applications in this call are not explicitly provided, but historical data indicates a general success rate for similar calls within the Innovation Actions framework ranges from 10% to 20%. Co-funding requirements are not specified but are typically expected in Horizon Europe grants. In summary, this opportunity seeks innovative solutions to improve thermal energy management in data centers, enhance energy efficiency, and foster a greener and more sustainable environment in line with the EU's strategic energy objectives.
