Abstract: Within this work, reticulated monolithic foams and granules made from CaMnO3 − δ and strontium substituted variations are demonstrated to significantly improve the performance of a water splitting redox oxide when employed as a thermochemical oxygen pumping...
In solar reactors for making solar fuels at high temperatures, ceria's behavior when heated makes it state-of-the-art for unlocking the thermochemistry involved. (How solar fuels are made). But its structure lacks “intelligent design.” So a precisely controlled design...
Abstract: La and Yb were incorporated as co-doping elements into Zr-doped ceria to investigate the influence of doping ions by means of ionic radius and valence on the ceria crystal lattice and potentially on thermodynamic and kinetic properties relevant to...
Abstract: Drop-in fuels produced using solar energy can provide a viable pathway towards sustainable transportation, especially for the long-haul aviation sector which is strongly dependent on jet fuel. This study reports on the experimental testing of a solar reactor...
Adding nickel to ceria can yield solar syngas at lower temperatures - at just 700°C Solar thermochemistry researchers at the University of Florida and Synhelion tried a new way to generate syngas, the precursor to hydrocarbon fuels like jet fuel or diesel. Solar...

Could the Chemical Potential Analysis method work better than the van't Hoff method? NREL’s Stephan Lany proposes a new common language to help solar thermochemistry researchers select the redox materials that will most efficiently generate green hydrogen. He has...
Three and a half years after a group of undergraduate researchers at Indiana’s Valparaiso University stored heat at 1000°C, they have extracted the heat in a proof of concept demonstration of the extremely long-duration potential of the redox cycle for solar...
TOPCSP, a new doctoral network aims to be the first PhD training program to respond to the growing need for qualified CSP researchers New ways are being developed to replace the combustion of fossil fuels for industrial processes that require heat, using concentrated...
Abstract: We report on an experimental parametric study performed on a modular and fully automated solar fuel system for the solar-driven thermochemical splitting of CO2 and H2O. Concentrated solar energy is used as the source of high-temperature process heat for...
Abstract: Ceria-based H2O/CO2-splitting solar-driven thermochemical cycle produces hydrogen or syngas. Thermal optimization of solar thermochemical reactor (STCR) improves the solar-to-fuel conversion efficiency. This research presents two conceptual designs and...
Synhelion's solar receiver achieves a temperature of 1,500°C and higher. That's unprecedented. Even the Gen3 particle-based solar receiver being pilot-scale tested now at Sandia - and the DLR CentRec receiver licensed to Heliogen - operate at the (relatively!) lower...
Abstract: This study analyzes the technical performance, costs and life-cycle greenhouse gas (GHG) emissions of the production of various fuels using air-captured water and CO2, and concentrated solar energy as the source of high-temperature process heat. The solar...
Solar even under grey skies 365 days a year: Typically, simplicity equals low costs. But the creators of a multi-technology thermochemical energy storage system for Gen3 concentrating solar power (CSP) claim that their complex design would bring costs down by enabling...
Heat-recovery ideas for solar reactors existed as theories “but not to actually go to the lab, build a device and try to make it work.”

Summary: Developing solar technologies for producing carbon-neutral aviation fuels has become a global energy challenge, but their readiness level has largely been limited to laboratory-scale studies. Here, we report on the experimental demonstration of a fully...
A “hot solar” tower fuel plant for thermochemical aviation fuel from H2O + CO2 is finally getting news coverage. What was your breakthrough?
The ETH spin-off Synhelion is working on commercializing its very high-temperature solar thermochemical fuels (like jet fuel and hydrogen) and has already formed partnerships with several larger firms making cement or aviation fuel to advance step by step towards its...
A perovskite may be more cost-effective than ceria for solar-driven thermochemical hydrogen production, a new paper suggests. One perovskite formulation that works at a slightly lower temperature than ceria is explored by Xin Qian in the paper Outstanding Properties...
