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...
Solar researchers at Fraunhofer Chile have designed, built, and tested a complete solar collector and crucible system for melting and recycling aluminum, heated by Annular Fresnel solar collectors. In Annular Fresnel, each mirror is flat, like a Fresnel mirror, but...
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...
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...
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...
Solar calcination + sCO2 cycle In a year-round California-based study, a Chilean research team has continued to advance a potentially more cost-effective and efficient form of Concentrated Solar Power (CSP) that leverages limestone's heat generation during...
Dr.-Ing. Wei Wu (born 1983) is the founder and managing director of Heatrix, a Bremen-based startup that she co-established with her co-founder, Dr.-Ing. Stefan Gasow-Lux. With a degree in aerospace engineering from the University of Stuttgart and a doctorate in...
Abstract: Improving the operating temperature of the solar receiver can enhance power cycle efficiency in solar power towers by raising the turbine-inlet temperature. However, maintaining high efficiency and safety at ultra-high temperatures (>1573 K) remains...
Collaborating with Synhelion engineers, a solar research team at the Solar-Institute Jülich (SIJ) of FH Aachen presented two papers at SolarPACES 2025 assessing the accuracy and reliability of dynamic process models for a solar fuel production system. They used...
Abstract: The reverse water gas shift (RWGS) reaction is a key pathway for CO2 utilization, particularly within Power-to-X process chains aimed at sustainable fuel and chemical production. Countercurrent chemical looping (CL-RWGS) using non-stoichiometric oxides can...
Abstract: As Concentrating Solar Power (CSP) technologies aim for higher operating temperatures to enhance efficiency and meet industrial process heat demands, high-temperature metallic materials, including nickel-based superalloys, face challenges in maintaining...
Abstract: Pumped thermal energy storage (PTES) is an innovative physical energy storage technology that converts surplus electricity into heat, stores it in thermal reservoirs, and reconverts it into electricity when needed. When CO2 is employed as the working fluid,...
Abstract: The parabolic trough collector remains one of the most extensively deployed technologies for concentrating solar power and heating. Enhancing the thermal performance of the receiver tube, which is its core component, is critical for improving overall system...
Abstract: Growing energy demand and environmental pollution issues are placing greater demands on sustainable thermal energy storage. Research indicates that molten salt phase change materials (MSPCMs) represent a promising alternative for thermal energy storage...

A NASA-funded research team at Georgia Tech has developed a method for extracting water from the Moon to generate the hydrogen and oxygen needed for propulsion fuels for solar system exploration. They describe their experimental work in Thermal extraction of H2O(s)...
Abstract: Currently the thermal effect of light has received extensive attention in the field of concentrating solar power gasification, but the non-thermal effect of light has been neglected. In this study, a high-flux solar simulator was coupled with a...
The 2025 Technology Innovation Award was jointly presented to ODQA, a University of Oxford spin-off, together with KTH Royal Institute of Technology, for their pioneering work advancing high-temperature air-based industrial heat. ODQA’s rotary receiver generates air...
Following their review, published at Astra Astronautica, covering all previous research using concentrated solar energy to generate heat for melting lunar regolith, co-authors Stéphane Abanades, Sylvain Rodat and PhD student, Jack Robinot, propose that the most...
On the closing day of SolarPACES 2025 in Almeria, NREL’s Mark Mehos and Craig Turchi were jointly recognized with the Lifetime Achievement Award for transformative leadership in advancing the commercialization of concentrating solar power. Mehos, now Principal...
