A new paper from researchers at PROMES-CNRS in France presents a control strategy to reliably deliver a precise thermal power from concentrated solar to meet industrial heat requirements. The objective was to design a proof-of-concept algorithm for operating a concentrated solar plant, but one intended primarily to deliver heat, and deliver it from thermal energy …

Abstract: Concentrated solar energy can be used as the source of heat at above 1000 °C for driving key energy-intensive industrial processes, such as cement manufacturing and metallurgical extraction, contributing to their decarbonization. The cornerstone technology is the solar receiver mounted on top of the solar tower, which absorbs the incident high-flux radiation and heats …
Abstract: Carbon-neutral fuels are key to decarbonizing hard-to-abate sectors. Solar redox cycles can produce them by creating oxygen vacancies in a metal oxide capable of splitting water and CO2. The resulting synthesis gas can be processed into a liquid fuel like methanol. To close the carbon cycle, feedstock CO2 can be captured from the atmosphere …
Abstract: Promising new receiver-reactor concepts with multiple apertures have been proposed for high temperature solar thermochemical hydrogen production. However, limited information about suitable solar concentrator designs consisting of heliostat fields and secondary concentrators is available so far. The goal of this study is a detailed investigation of the effect of selected solar concentrator design parameters …
Press Release Zurich, December 16, 2025 Swiss International Air Lines (SWISS) and Swiss cleantech company Synhelion have signed a long-term offtake agreement for sustainable aviation fuel (SAF). From 2027, SWISS will purchase at least 200 tons of solar jet fuel from Synhelion annually, pioneering the use of this innovative fuel in civil aviation. The agreement …

Abstract: The use of renewable energy in the context of green hydrogen production requires suitable energy storage technologies to compensate for intermittent wind and solar resources. High-temperature electrolysis is a promising way to produce hydrogen as it has the highest electrical efficiency by using steam instead of liquid water compared to low temperature electrolysis. Here, …
Abstract: Decarbonisation of the energy sector is critical for climate change mitigation, with the power sector remaining a major contributor to global emissions. Concentrating solar power (CSP) technology combined with thermal energy storage (TES) presents a promising solution to overcome this challenge. TES systems, particularly those utilising phase change materials (PCMs), offer efficient energy storage …
Abstract: The Performances of direct absorption solar collectors (DASC) are limited by the stability of the nanofluid’s optical properties. This study investigates the performance and long-term stability of a graphene-based nanofluid under real on-sun operating conditions using an experimental parabolic trough pilot. The on-sun experiments were complemented with a detailed off-sun experimental evaluation of the …
