Excess heat from energy-intensive industries is often suitable for use in district heating systems but is usually unutilized. A detailed overview of the potentials available in the EU is now provided by a database of the sEEnergies project. In Germany, 29 petajoules of excess heat from industrial sites could be used, which corresponds to the demand of more than half a million households. The information is available as maps and downloadable datasets.
“Heating and cooling planning for greener cities: local resources first” was the topic of the final conference of the Hotmaps project. The event took place entirely online and included different plenary and parallel sessions. Around 70 people remained online all the time.
The HotMaps project designed a toolbox for the EU28 to support public authorities, energy agencies and urban planners with strategic heating and cooling planning on local, regional and national levels in line with EU policies. Fraunhofer ISI developed an open-source industrial database that identifies industrial excess heat potentials for energy-intensive industries and provides load profiles for the heating demand of all sectors. Together with the heating density in the toolbox, this makes it possible to assess the match of future heating demand and supply at hectare level.
In the final conference, the toolbox was presented and it was demonstrated how the different stakeholders involved in heating and cooling (H&C) planning can use it in their daily work:
