The MEMPHIS Project plan is structured into four work packages following the project’s logical concept.

WP 1: Development of a generic methodology for assessing waste heat potentials

  • Collect required data from public sources (statistical institutes and studies), determine data on economic activities and energy consumption.
  • Collect data and develop characteristic key figures for waste heat producer in SME / industry / other.
  • Apply and verify the methodology for a example city of Austria.

WP 2: Development of a generic methodology for assessing sewage heat potentials

  • Elaborate a database of country-specific key figures for typical wastewater flows and temperatures in different sectors (residential areas, commercial and institutional facilities, various industries).
  • Determine international available open data (e.g. OpenStreetMap data) to characterise city districts in terms of population, service sector and industry density.
  • Test methodology at the example of a German city. Check plausibility of results with data from water supply and sewage plant records.
  • Elaborate temperature profiles of wastewater flows taking into account outdoor temperature fluctuations and heat losses in the sewage System.
  • Map the sewage heat potential on a city district level using GIS.
  • Assess economic and technical feasible locations for integrating sewage heat into DH system.
  • Prepare an online documentation of the methodology.

WP 3: Application and impact Analysis

  • Assess impact on DH network (verify low/high temperature from companies and sewage pipes)
  • Determine regulative boundary conditions/barriers to industrial/service sector waste heat and to sewage water heat recovery in Austria, Germany and United Kingdom.
  • Analyse market maturity and supply chain in Germany, Austria and United Kingdom with outlook to other IEA DHC member states.
  • Apply new methodology for industrial/service sector waste heat and new methodology for sewage water heat recovery in one German, one Austrian and one UK City.
  • Develop business models for waste heat utilisation for example city in Germany, Austria and UK.
  • Evaluate transferability of methodology to other IEA DHC member states.

WP 4: Dissemination and Project Management

  • Overall project management and coordination
  • Website
  • Dissemination events
  • Research papers
