The integration of waste heat from industrial processes has been identified as a major research area in the EU strategy on heating and cooling. In fact, the waste heat potential of combined heat and power stations (CHP) or energy-from-waste plants is well understood and district heating (DH) networks in markets with varying maturity across the world utilise this typically high-grade type of waste heat. The MEMPHIS project builds upon previous research from the project partners and other researchers in the DH sector and focusses on the potential and feasibility of supplying urban areas with low-grade waste heat.
Research area: The project „MEMPHIS: Methodology to evaluate and map the potential of waste heat from industry, service sector and sewage water by using internationally available open data“ will address this issue through the analysis of low-grade and spatially distributed heat potentials from small and medium industries and the service sector as well as from sewage water systems.
Target audience and specific issues: A transparent, publicly accessible and internationally applicable methodology helps national heat policy makers to promote the usage of low-grade waste heat across a country. Local authorities, city planners and developers will be able to use the tool to identify maximum size and diversity of waste heat potential at local level. This can improve decentralised energy master planning for new DH or future-proofing strategies for existing and/or expanding networks. The methodology will be applied at three example cities in Germany (City of Mannheim), United Kingdom (City of Edinburgh) and Austria.
The advantage of the three countries for investigation is the different degree of diversification in economy and spatial distribution of services and industry across urban areas, which will provide a good basis for the development of an international methodology. Eventually, an outlook into the transferability of the method to other IEA member countries will be carried out.
This project is funded by IEA DHC – the International Energy Agency Technology Collaboration Programme on District Heating and Cooling including Combined Heat and Power.
