IEA SHC Award 2022 recognises outstanding social housing projects

The IEA SHC Solar Award 2022 will recognise an organisation or individual that implemented a solar heating or cooling project in the last five years to cut energy consumption and costs in social housing. In order to win, the nominees will have to demonstrate that the use of solar thermal …
Molten salt: suitable heat-transfer fluid for concentrating collector fields

Molten salt: suitable heat-transfer fluid for concentrating collector fields

In a parabolic trough collector demo plant run by the German Aerospace Center (DLR) in Évora, Portugal, molten salt is used as a heat-transfer fluid instead of thermal oil. The advantage of molten salt is its stability at higher temperatures. Whereas thermal oil cracks at above 400 °C, molten nitrate …
Cautious optimism for the coming years in Spain

Cautious optimism for the coming years in Spain

The Spanish residential solar thermal market is showing signs of resurgence. After a decline of 8 % in 2020 due to Covid-19, the market experienced 1 % growth in the first half of 2021, according to the solar thermal association ASIT. Solar PV seems an ever-harder contender, sometimes battling for …
Between three and eight million heat pumps in 2030

Between three and eight million heat pumps in 2030

The German heat pump industry expects high growth rates in the next years. The latest heat transition reports predict between three and eight million heat pumps in operation in German buildings by 2030 to fulfil the climate goals (see chart below). By the end of 2020, a total of 1.4 …

Founders of Clean Heat Forum contemplate a variety of strategies

During last week’s COP26 in Glasgow, the UK government launched a Clean Heat Forum to accelerate the decarbonisation of heat used in buildings. The platform will be managed under the umbrella of the Global Alliance for Buildings and Construction (GlobalABC), founded at COP21 in Paris in 2015. “As the UK, …
Launch of Solar Thermal Yearbook 2021

Launch of Solar Thermal Yearbook 2021

Solar thermal energy is indispensable for the energy transition, but just as indispensable is informing the interested public about the state of the art and the wide range of possible solar heat applications. This is the motivation of the editorial team for launching the first English language edition of the …
Standardised yield assessments for industrial solar heat plants

Standardised yield assessments for industrial solar heat plants

The yield of solar process heat systems as simulated during feasibility studies has a decisive influence on the profitability of the respective investment. Therefore, simulation tools play an important role in the project development phase. Currently, however, project developers use a large number of simulation tools, whose results may differ …
