IEA DHC Annex TS7: Industry-DHC Symbiosis - A systemic approach for highly integrated industrial and thermal energy systems
Renewable and excess heat sources are currently representing nearly a third of the energy supply used in the DHC sector. Excess heat has the potential to further grow to become an important part of the energy puzzle. Up to 25% of district heating could be covered by industrial excess heat and more than 10 % of the EU's total energy demand for heating and hot water could be covered by heat from data centres, metro stations, service sector buildings, and waste-water treatment plants.
IEA DHC TS5 - Integration of Renewable Energy Sources into existing District Heating and Cooling Systems (RES DHC)
The expansion of sustainable district heating/cooling is an essential part of the Austrian heat transition. The transformation of these supply systems to fully renewable systems requires the combination of a multitude of aspects. The aim of the project is to compile a data and knowledge base from international projects in this context. Expertise and process know-how for the process of implementing the transformation of district heating and cooling systems will be collected and processed.
IEA DHC Annex XIII Project 02: MEMPHIS 2.0 - Advanced algorithm for spatial identification, evaluation of temporal availability and economic assessment of waste heat sources and their local representation
The identification and integration of waste heat sources is a key measure towards the decarbonisation district heating networks (DHN). Aim of MEMPHIS 2 is to develop an improved algorithm for identification of different current and future waste heat sources; including time relations of the heat emitted and techno-economic details as well as the further development of the online waste heat explorer.
IEA DHC Annex XIII Project 07: CASCADE - A comprehensive toolbox for integrating low-temperature sub-networks in existing district heating networks
The majority of urban district heating networks operate at high temperatures, which are a barrier to the efficient integration of heat sources such as solar, geothermal, ambient or low temperature waste heat. CASCADE is investigating the integration of low-temperature networks into the return pipe of existing district heating networks, which will reduce return temperatures and thus improve efficiency and increase its capacity to connect new customers.
IEA DHC Annex TS4: Digitalisation of District Heating and Cooling
The aim of the IEA DHC Annex TS4 is to identify the possibilities of digitalization and the integration of digital process for district heating and cooling. To this end, the Annex TS4 establishes a platform for industrial and scientific experts to strengthen international cooperation and networking and the exchange of experience of national research and development activities.
