STSHC collaboration group: advancing hybrid solar process cooling
Solar thermal cooling systems reach a much higher electrical efficiency ratio (EER) than cooling by electricity-driven compression chillers, hence limiting additional pressure on electricity grids. Furthermore, thermally-driven chillers are more robust units with fewer moving parts than compression refrigeration machines. These advantages are not yet very well understood, although the …
PVT collectors and ice storage heat sustainable district in Luxembourg
A new residential district is currently taking shape in the small town of Wiltz in northern Luxembourg. Its heating supply will rely entirely on PVT collectors, ice storage systems and heat pumps. In the sustainable neighbourhood of Wunne mat der Wooltz (Living with the Wooltz River), a total of 3,000 …
Two solar-to-hydrogen approaches to be presented in webinar
How can solar energy be used not only to generate electricity and heat, but also to produce green hydrogen? Researchers in IEA SHC Task 72, titled Solar Photoreactors for the Production of Fuels and Chemicals, are addressing this challenge. One approach is pursued by Australian company Sparc Hydrogen, established in …
SunPeek wins 2026 STSHC Solar Award for advancing performance monitoring
The SunPeek Open-Source Project has won the 2026 Solar Award by the IEA Solar Technologies & Sustainable Heating and Cooling Programme (IEA STSHC). SunPeek is a software designed to verify whether large-scale solar thermal plants deliver the heat output they should. Maria Moser from the Austrian company SOLID (centre) and …
Europe’s solar heat market: A mixed picture across countries and applications
In its latest market report, Solar Heat Europe once again does an excellent job of bringing together key figures and trends from across the EU member states, while also promoting solar thermal as a clean tech made in Europe. Sales of solar thermal systems in residential markets continue to be …
PVT heat pump systems demonstrate performance factors above 3
PVT collectors were a major topic at the Eurosun conference held in mid-September in Freiburg, Germany. Three sessions featured presentations on new developments and projects in the field. Particularly valuable were the contributions by Bharat Chhugani from the German Institute for Solar Energy Research Hameln (ISFH) and Laetitia Brottier from …
50th anniversary: IEA SHC marks a new chapter with updated name and visual identity
What better way to celebrate 50 years of international research collaboration than with an evening of inspiring stories, good company, and a special birthday cake? At EuroSun mid-September, the IEA SHC Programme celebrated Five Decades of Innovation through Research Collaboration – looking back at a remarkable journey and honouring some …
Happy birthday EuroSun: 30 years of bringing solar research together
The EuroSun conference of the International Solar Energy Society (ISES) returned to Freiburg last week, exactly 30 years after the first EuroSun was held in the same city in 1996. Some 370 participants gathered for three days of keynotes and technical sessions covering eleven topics. The simultaneous organisation of EuroSun …
