IEA SHC Task 67: Compact Thermal Energy Storage Materials within Components within Systems
This Task aims to push forward the compact thermal energy storage (CTES) technology developments to accelerate their market introduction through the international collaboration of experts from materials research, components development and system integration. These technologies are based on the classes of phase change materials (PCM) and thermochemical materials (TCM). Materials from these classes will be studied, improved, characterized and tested in components.
Process Heat Collectors State of the Art within Task 33/IV (Weiss/Rommel 2008)
Approximately 128 GWth, the equivalent of 183 million square meters, of solar thermal collectorswere installed by the year 2006 worldwide (Weiss et al., 2008). Until now, the widespread use of solarthermal applications has focused almost exclusively on swimming pools and residential domestichot water preparation and space heating.

IEA-SHC Task 66: SOLAR ENERGY BUILDINGS - Integrated solar energy supply concepts for climate-neutral buildings and communities for the "City of the Future”
The energy supply for climate-neutral buildings is based on holistic system concepts that achieve high renewable fractions by intelligently combining technologies, sector coupling, high grid interaction and flexibilization measures. The Solar Energy Buildings Task supports exactly this development. The objective is to identify relevant stakeholders and their needs, to develop a technology portfolio and optimised integrated energy concepts and to give recommendations to policy makers and energy-related companies.
IEA PVPS Task 1: Strategic PV Analysis & Outreach (Working period until 2022)
This task, which is mandatory for all countries participating in the IEA-PVPS program, has been producing global reports on photovoltaic development since 1993. In addition, content-related priorities are set, or new topics and tasks are developed, which are then sent to the ExCo for decision-making. This gives Task 1 strategic importance for the overall IEA PVPS program.
IEA Wind Task 41: Enabling Wind to Contribute to a Distributed Energy Future (Working period 2019 - 2023)
IEA Wind Task 41 aims to create framework conditions for decentralised small and medium-sized wind turbines in order to establish them as a competitive and reliable technology for decentralised energy generation. A strategic focus in the pursuit of this goal is the revision of the IEC standard for wind turbines, taking into account the latest research results.
IEA SHC Task 72: Solar Photoreactors for Fuels and Chemicals (working period 2024 - 2028)
With the increasing demand for green fuels and chemicals, solar-based photoprocesses that utilize direct sunlight are gaining importance. The IEA SHC Task 72 aims to develop new materials, reactor designs and system integration strategies as well as standardized test and evaluation protocols in an interdisciplinary approach to ultimately pave the way for future solar photoreactors as new market segments for the solar industry.
IEA SHC Task 52: Solar Thermal & Energy Economics in Urban Environments
IEA SHC Task 52 focused on the analysis of the future role of solar thermal heat in integrated urban energy systems. The potential of solar thermal applications to cover the low-temperature heat demand in future low-carbon energy systems was investigated against the background of the rapidly changing framework conditions in the energy sector. Best practice examples for the integration of solar thermal systems into urban energy systems were evaluated and documented.
IEA SHC Task 62: Solar Energy in Industrial Water and Wastewater Management
The main objective of IEA SHC Task 62 was to increase the use of solar thermal energy in industry, to develop new collector technologies and to open up industrial and municipal water treatment as a new area of application with high market potential for solar thermal energy. The focus was on thermal separation technologies as well as technologies for solar water decontamination and disinfection. By combining the technologies with solar collectors, an innovative and economically attractive overall solution should be created for integration into industry.
IEA SHC Task 69: Solar Hot Water for 2030
Solar water heating will play a crucial role in the decarbonization of the energy system for 2030 and beyond. IEA SHC Task 69 focuses on two technologies which are likely to play the biggest role in the global solar hot water market: thermosyphon and photovoltaic (PV) hot water systems. For these technologies global market surveys, systems and component optimizations, cost reduction analyses and revision of standards are being conducted to accelerate growth in target markets.
IEA SHC Task 70: Low Carbon, High Comfort Integrated Lighting
With the goal of decarbonization and sustainability of buildings in the sense of the circular economy, for integrated lighting systems the so far purely energy-based focus must be broadened to include the entire life cycle, with special consideration of visual and non-visual user requirements. In the task, strategic, technical, and economic information will be developed for the relevant stakeholders and networking activities will be offered.
