Description
Heat recovery systems are seen as energy efficient actions and can reduce gas consumption by close to 80%, at the price of significant investments for existing systems. Close to 10 years ago, two multi MW cases were identified on existing infrastructure at CERN. A first project of 10 MW with a local community was studied, confirmed viable and launched with a convention signed in 2019 and now ready to be tested. Since, a new computing center was being considered, for which a possibility to consider heat recovery was added as an incentive in the tendering process. With economic criteria aligned with sustainability considerations, refurbishments of the two existing heating plants are now ongoing with multi MW heat recovery loops. With all teams now familiar with corresponding technologies and experienced gained, the possibility to include heat recovery in future projects is now the baseline, and would be implemented if a synergy is found with internal or external users for heat.
The projects, key parameters and evolution of approach will be presented.
