IEA DHC Annex XIV project 04: RE-PEAK - How to cover peak heat loads in DH networks with renewables?
One challenge for the decarbonisation of many district heating networks (DH) is the provision of peak load. The objectives of the RE-PEAK project are: to gain a better understanding of the specific problems, to collect empirical data on the provision of peak load, to analyse the perception of district heating network operators with regard to the transition to climate-neutral peak load coverage, and to consolidate the results and derive recommendations.
IEA DHC Annex TS9: Digitalisation of District Heating and Cooling – Improving Efficiency and Performance Through Data Integration (Working period 2024 - 2028)
To successfully digitalize district heating and cooling (DHC), it is important to understand the benefits of incorporating digital processes into DHC networks. The purpose of this project is to investigate solutions for data transfer and processing between the components of DHC networks, with a focus on interoperability and standardization. Furthermore, non-technical hurdles and enablers to digitization processes in the DHC sector are assessed.
IEA DHC Annex TS8: Experimental investigations of DHC systems
The project aims at promoting and improving the use of experimental studies for the transformation, decarbonization and flexibilization of new and existing district heating and cooling (DHC) systems. A strong focus will be on the integration of digital technologies, both in terms of application (e.g., IoT and cloud solutions, digital twins, machine learning) and experimental implementation (e.g., hardware-in-the-loop, data spaces).
IEA DHC Annex TS3: Hybrid Energy Networks, District Heating and Cooling Networks in an Integrated Energy System Context Guidebook
Hybrid energy networks, i.e. the integration of electricity, heat and gas networks, can make a decisive contribution to optimizing the energy system. The IEA DHC Annex TS3 analyses the potentials and challenges of hybrid energy networks from the perspective of the district heating / cooling system. This is including the analyses of relevant technologies and synergies, an assessment of the different methodological approaches and tools, the analyses of case studies as well as the development of suitable business models and regulations.
IEA DHC Annex XIV project 06: HY2HEAT Using electrolysis waste heat in district heating networks
Hydrogen will primarily be produced by electrolysis, however, approximately one third of the electricity used to generate the hydrogen will be wasted as heat. The aim of HY2HEAT is to analyse the techno-economic synergies of electrolysis waste heat integration in District Heating systems, to evaluate the best technical solutions and to derive a practical guide for District Heating operators.
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.
