Throughout Europe, there are thousands of urban sources of waste heat. Combined, there is enough waste heat produced in the EU to heat the entire building stock, sources ranging from large high temperature industrial sources to small scale comfort cooling systems. But despite this huge potential, there are only a few small-scale examples of urban waste heat recovery across the EU.
Below are listed examples of when waste heat is being used. These cases serve as small-scale inspirational projects on how to utilize waste heat from urban sources, for both heating and cooling purposes. Most of the cases exploit small-scale recovery ranging from some hundreds of kilowatts to a few megawatts. The sources are often low-temperature waste heat sources, utilized by heat pumping technologies for district heating network solutions.
The collection of brief techno-economic case studies
There are 25 cases in the collection, where of 12 cases are Danish. Most of the cases originate from the EU financed ReUseHeat project. The locations are plotted in figure 1.
