International Energy Agency’s Solar Heating and Cooling Programme
The IEA Solar Heating and Cooling (SHC) Programme has over 35 years of international collaborative work in the field of research, development, demonstration (RD&D) and test methods for solar thermal energy and solar buildings. The results of this work are available for researchers, policy makers, industry, utility and business representatives, builders, architects and teachers.
The IEA SHC Programme is a member-based Programme with 20 member countries and 5 member organizations. Its mission is “To enhance collective knowledge and application of solar heating and cooling through international collaboration to fulfill its vision of solar thermal energy meeting 50% of low temperature heating and cooling demand by 2050."
Project (Task) Description
Solar District Heating (SDH) is in the early market development stage. Large solar thermal plants feeding into district heating networks represent only about 1% of the installed capacity of solar thermal systems, despite the fact that competitive prices lower than 40 €/MWh can be reached. In the long run, solar district heating could represent 4-15% of the total technical potential of solar thermal energy.
Today, the commercial application of Solar District Heating is spreading to several countries. In particular in Denmark, where SDH is operated at feasible heat costs and the building of plants is booming. SDH activities are also well underway in Austria and in the implementation phase in Germany, Italy, France, Spain and Norway.
This Task aims to develop technical and economic requirements for the commercial market introduction of solar district heating and cooling (DHC) for a broad range of countries. The activities aim to improve technological know-how, market know-how and understanding of the boundary conditions as well as to provide expert know-how for project initiation and implementation and for training. A key element will be the direct cooperation of SDH experts with associations and companies in the district heating sector as a means to bridge the gap between these sectors.
- Characteristics of solar thermal systems for DHC >0.5 MW up to GW systems
- Technical and economic specifications of district heating networks which are relevant for the integration of solar thermal systems and hybrid technologies (large scale storages, industrial waste heat, heat pumps, etc.)
- Analyses of system components and their integration: system temperature requirements, optimization of hydraulic systems, interdependences between large collector fields and seasonal storages, control strategies, self-learning controls, large collector field performances, assessment and design of large seasonal storages (>50.000 m³), system performance guarantees, system ratings and certificates
- Modular design of large SDH/SDC systems including hybrid technologies (large scale storages, industrial waste heat, heat pumps, etc.)
- Up-scaling potential of existing medium/large SDH/SDC systems to up to GWth systems
- Economic requirements of large SDH/SDC systems, market analyses of global and country developments
Cooperation with IEA DHC
The IEA Technology Collaboration Programme on District Heating and Cooling including Combined Heat and Power (IEA DHC) officially cooperates with Task 55 of the IEA Technology Collaboration Programme on Solar Heating and Cooling (IEA SHC). The SHC Task 55 will integrate input provided by IEA DHC in its publications and communication, and receive reviews for Subtask A and additional information from the IEA DHC.
