Hybrid solar collector unlocks triple solar energy harvesting
A solar collector can do more than just generate heat. As a hybrid collector, it can simultaneously produce fuel and electricity as well. Scientists from IEA SHC Task 72 are working on the development of such versatile solar elements for solar photoreactors for the production of fuels and chemicals. The …
Growing demand for industrial heat pumps drives innovation in heat exchangers
Demand for industrial heat pumps is growing. Customers want heat pumps with large capacities and, if possible, with natural refrigerants. This calls for advanced heat exchangers for condensers and evaporators. The German agency solrico conducted a survey among heat exchanger manufacturers to find out what requirements are placed on heat …
Smart controls and low PV costs drive growth in PV hot water
PV hot water systems are growing fast in several regions. Growth is strongest in countries with high PV market penetration or less mature electricity systems. Falling PV hardware prices and smarter control technologies are driving this trend. In a recent IEA SHC Solar Academy webinar, UK-based consultant Tony Day explained …
PVT prices are falling while local production and supply chains continue to strengthen
The European PVT collector industry is undergoing a significant transformation, with manufacturers focusing on increasing production efficiency, improving quality assurance, and reducing dependence on imported components, particularly from China. These developments are the findings of a workshop on production and supply chain strategies for PVT collectors, organized by the PVT …
Technical training and gender empowerment: solar thermal experts gather in Windhoek
Technical and social issues were on the agenda at the SOLTRAIN+/IEA SHC Task 69 Joint Symposium held in Windhoek, Namibia, at the end of September. The first day focused on standards and certification training, while the second day centred on gender equality and women’s empowerment. The event was jointly organised …
Site selection and feasibility assessment for pit thermal energy storage
The EU-funded Treasure project aims to process the lessons learned from existing pit thermal energy storage installations in order to simplify the planning and implementation of follow-up initiatives. Per Alex Sørensen from the Danish consultancy company PlanEnergi has developed a special methodology for this purpose. He organizes a series of …
Treasure project accelerates pit thermal energy storage expansion across Europe
Pit thermal energy storage (PTES) represents a key enabling technology in future heating networks powered by fluctuating renewable energy sources. These storage systems provide a cost-effective solution for storing surplus thermal energy over periods ranging from days to entire seasons. Currently, there are eight PTES installations in operation in Europe …
Europe’s largest PVT system heats Vienna’s new Sport Arena
The PVT collector market continues to establish itself in Europe. The new Sport Arena in Vienna is home to what is currently the largest PVT system in Europe, with 1,130 collectors from the German supplier Sunmaxx PVT. It surpasses the installation at the Barcelona Swimming Club in Spain, which features …
