Namibia study comparing thermosiphon and PV-to-heat systems sparks interest at ISEC 2026
ISEC 2026 in Graz, Austria, became a major international meeting point for the energy transition. Around 550 experts from 42 countries gathered to discuss technological developments, global research cooperation, regulatory frameworks and renewable energy projects. The conference was organized for the fourth time by the Austrian research institute AEE INTEC …
Webinar to introduce Eurosun2026 and SolarPaces 2026 cooperation
The international solar thermal community will gather in Freiburg, Germany, from 14 to 18 September 2026 for EuroSun2026, one of the sector’s leading scientific conferences. At the same time, Germany will also host SolarPACES 2026, creating a unique opportunity for closer collaboration between the global communities focusing on solar heat, …
PVT readiness of heat pumps – definition and market overview
PVT collectors can make highly efficient heat sources for heat pumps, but they also create special technical challenges. Unlike conventional heat sources such as ambient air or shallow geothermal energy, PVT collectors deliver a much wider and more dynamic temperature range. In summer, the brine temperature can rise to 70 …
Outlook 2026–2028: mapping the future of industrial solar heat
The project pipeline of solar industrial heat developers is robust and expanding. For the Solar Industrial Heat Outlook 2026–2028, developers reported 65 projects with a weighted capacity of 223 MW. “Weighted” means that each project is included in the Outlook according to its likelihood of implementation – counted at 30%, …
SHIP market declines in 2025 despite broad industrial adoption
In 2025, solar heat for industrial processes (SHIP) continued to be deployed across a broad range of industrial sectors, as illustrated in the chart above. Drying processes and barn heating systems accounted for the majority of new installations, while steam applications in the chemical and pharmaceutical industries were also among …
Main takeaways from IEA SHC Task 71: Towards unified metrics of LCA and LCoH for heating technologies
Karl-Anders Weiß has spent the past three years intensively working on the life cycle and cost assessment of alternative heating technologies. The researcher from the German institute Fraunhofer ISE has led Task 71 of the IEA Solar Heating and Cooling Programme on this very topic, which has now concluded after …
Momentum builds for solar thermal in Poland: Major plant, new tenders and EU Project LIGHT
The beginning of the year has brought a series of important developments for Poland’s solar thermal sector. Construction has started on the country’s largest solar district heating plant – an 12.3 MW installation in Gliwice in southern Poland (see photo) – with more calls for tenders for similar projects expected …
“We need tailed concentrating optics to boost the hydrogen production without cooking the reactor”
One of the strengths of the IEA Solar Heating and Cooling Programme is its ability to bring together scientists working on similar topics from across continents to exchange ideas. This was once again successfully demonstrated within Task 72 on Solar Photoreactors for the Production of Fuels and Chemicals. Prof. Craig …
