ReUseHeat: Collecting information on urban excess heat sources

There is enough waste energy produced in the EU to heat its entire building stock. Despite of this huge potential, only a few small-scale examples of urban waste heat recovery are present across the EU. The objective of ReUseHeat is to demonstrate first of their kind advanced, modular and replicable systems enabling the recovery and reuse of excess heat available at urban level, as well as to analyse the potential of waste heat by identifying urban sources and the amount of recoverable excess heat, with the aim of assessing the impacts that investments in this field can have on the national energy systems.

ReUseHeat will tackle both technical and non-technical barriers to unlock urban waste heat recovery projects and investments across Europe. There are four large-scale demonstrators in the project, showing the technical feasibility and economic viability of excess heat recovery and reuse from data centres (Brunswick), sewage water collectors (Nice), cooling system of a hospital (Madrid) and an underground station (Bucharest). The experience from running the demonstrators and from other examples across the EU will be consolidated into a handbook that will provide guidance for investors and project developers and support future uptake of using urban excess heat. It will include innovative and efficient technologies and solutions, suitable business models and contractual arrangements, authorisation procedures, estimation of investment risks, bankability and impact of urban excess heat recovery projects.

 

ReUseHeat project has received funding from the European Union’s Horizon 2020 research and innovation programme under Grant Agreement No 767429.

This survey aims to be a very useful tool for identifying the potential of urban excess heat sources by contacting relevant actors and stakeholders across the EU, with particular focus on the four ReUseHeat demonstrator cities. By filling in this survey, the data of your facilities will be part of an open and public database, contributing to taking a step forward towards the final objective of reaching a more sustainable and decarbonised energy model in Europe!
