Currently, the huge potential of data centre waste heat for the decarbonization of the heating sector is often ignored. Here, a feasibility study is presented for covering the heat demand of two districts of Frankfurt (Germany) mainly by data centre waste heat. Contrary to many other studies, the total heat demand (144 GWh/a) is to be covered almost exclusively with waste heat integration, the district heating network is not existing yet and the buildings to be connected are not particularly energy efficient. In this study, the potential and demand are estimated, a heating supply concept is presented and evaluated regarding costs, heat pump capacity, and storage size. As a result, the utilisation of data centre waste heat is not only possible, but it is the most promising way for decarbonizing heating in the area under consideration. With high-capacity heat pumps (37 MWth), gas boilers (20 MWth) and a thermal energy storage for daily peaks, 97.5% of the heat demand can be covered with waste heat usage. It is economically favourable compared to individual heat pumps for all types of buildings and with the proposed concept, CO2 emissions in the district heating network area are reduced by 78% on average.
