Waste heat atlas - A survey, estimate and evaluation of industrial waste heat in Germany - Potentials and need for research

Through the research project, the strategic framework shall be developed in order to get started with coordinated systems research on the utilisation of waste heat. To this end, relevant data concerning waste heat sources in industry and data on technologies for utilising waste heat shall be compiled, updated and assessed as well as placed in a broader context. The aim of “Waste Heat Atlas” research project is to be able to make qualitative and quantitative statements on the topic of industrial waste heat in a national context. The first challenge in this process is to establish a data basis, from which potentials can be identified. Current statistical surveys, such as those conducted by the German Federal Statistical Office and by the AG Energiebilanzen, have shown that reliable facts on this topic are lacking. Within the framework of the research project, a questionnaire shall be therefore developed so that companies in the most energy-intensive sectors – based on a preliminary Pareto study – can be questioned on their unused industrial heat sources. The data from this representative nationwide survey shall serve as the basis for a nationally scalable estimate of the potential. Metrological tests of the plausibility of the data gathered shall be conducted in selected companies based in the area of Stuttgart and in the Ruhr district. In addition to potential heat sources, economic efficiency calculations of potentially viable waste heat utilisation technologies shall be generated for the companies examined. The research project shall also serve to introduce waste heat technologies and to quantify their potential. Above all, technologies for the small and medium term as well as waste heat utilisation systems which can be easily implemented shall be classified according to their relevance. Any obstacles, needs for research and ideas concerning the framework conditions shall act as action guidelines, factors stressing importance and control methods for policy, thereby rounding off the project.


>> An overview of the project


The project consortium shall be assisted by two associated partners: the German Federal Statistics Office (DESTATIS) and the German Institute for Economic Research (DIW Berlin). The research project coordinator is the Fraunhofer Institute for Physical Measurement Techniques.



Supported by:

The research project is supported by the German Federal Ministry of Economics and Technology (BMWI) and coordinated by Jülichs (PtJ), the project’s executing organisation.
