Parabolic trough collector field as part of 100 % carbon-free heat supply for food factory in Australia
Site work has started on what will be the largest concentrating solar heat project in the Australian food industry. An 18 MW parabolic trough field is to be built at the Mars Petcare facility in Wodonga in the state of Victoria. The EPC for the solar field is the Belgian …
National Day shines light on future potential and market realities
At the German National Day at the beginning of November entitled “Solar Technology for the Future”, the heat experts clearly pointed out the huge gap that currently exists between long-term potential studies and the actual market development of solar heat technologies. They made clear and precise demands to policy makers …
Technology Radar for Solar Energy Buildings
Buildings with a high solar fraction require a good mix of technologies and energy efficiency measures. The scientists of IEA SHC Task 66 on Solar Energy Buildings have analysed 150 such buildings and identified and listed the new and innovative elements. The Technology Radar for Solar Energy Buildings contains over …
22 inspiring solar neighborhoods depicted on a map
Urban surfaces play a major role in enhancing sustainability and climate resilience of neighborhoods. They offer opportunities not only for producing renewable energies and correctly managing passive solar gains and daylight, but also for greening and cooling the neighborhood. The researchers of IEA SHC Task 63 on Solar Neighborhood Planning …
High solar heat fraction solutions supported by heat pumps
The German heating technology manufacturer Viessmann Climate Solutions has been part of Carrier Global, the largest US manufacturer of air conditioning systems, since March 2023. This merger is now also beginning to bear fruit in Germany. The German town of Bracht is not only benefiting from a turnkey solar heat …
Industrial heat pumps provide up to 90 °C for district heating from river water or air
Two innovative heat pump projects in the megawatt range connected to district heating grids went into operation in Germany last year. The installations from Johnson Controls International (JCI), Denmark, and Friotherm, Switzerland, are both designed to provide hot water of up to 90 °C for their respective district heating networks …
A guideline for industrial heat pumps adapted to district heating networks
Solar thermal systems and heat pumps are important key components for the decarbonization of district heating networks and often complement each other well. Heat pumps can, for example, use heat from the solar-charged seasonal storage tank and thus empty it more efficiently. This boost effect of heat pumps was described …
Standardization and adaption of solar cooling kits for sunbelt regions
The future markets for solar thermal cooling systems are in the global south. The IEA study The Future of Cooling predicts that by 2050 37 % of total electricity demand growth will be for air conditioning. Solar thermal cooling systems have two major advantages. They consume up to a factor …
