According to incomplete statistics from CSPPLAZA, a total of 12 important tenders across 11 CSP/molten salt thermal storage-related projects were completed in December 2025. December 2025 saw significant progress in both concentrated solar power (CSP) and molten salt thermal storage, with key milestones reached in multiple major projects: In the CSP sector, EPC contractors were …

Abstract: Concentrating Solar Power (CSP) molten-salt central receivers are subject to high, transient incident flux during daily operation. The resulting creep-fatigue damage impacts the receiver’s reliability and restricts the permissible incident flux distribution for a given receiver. This paper aims to reduce CSP plants’ levelized cost of electricity by developing a methodology to predict lifetime …
Abstract: Direct absorption solar collectors have gained attention in the last decades as a promising solution to enhance the performance of conventional thermal collectors. In this concept, the heat transfer fluid absorbs the concentrated radiation volumetrically, which optical properties can be enhanced by dispersing nanoparticles. While several works have reported the benefits of volumetrically absorbing …
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 …
