Image ©Two-Step Thermochemical Conversion of CO2 using a Novel Nd1-xSrxMnO3 Perovskite. To lower the costs of solar fuels and thermal energy storage, concentrated solar thermal (CST) researchers are working on increasing solar thermochemistry’s performance and redox cycle-ability. Researchers at Khalifa University of Science and Technology have designed a perovskite mix that promises to achieve both …

Falling Particle Receiver research has been global. Dr Jin-Soo Kim in Australia’s Falling Particles Process Bay, Newcastle Energy Centre IMAGE©CSIRO Government-funded research into decarbonizing heavy industry using concentrated solar thermal (CST) yields results with the world’s first spin-off based on a new kind of high temperature solar receiver – the falling particle receiver. Because of …
IMAGE©S.Abanades and S. Chuayboon Green iron and syngas production via continuous solar-driven agricultural waste biomass gasification combined with iron(III) oxide reduction Two international concentrated solar researchers have demonstrated using concentrated solar heat to produce green iron and syngas from renewable biomass, using no-oxygen conversion in a gasifier for a carbon-free process. In their paper, Green …

The tubing that absorbs the solar heat reflected off the parabolic trough-shaped solar collector in Trough CSP is normally a metal. Researchers at PROMES-CNRS have instead trialed glass tubing filled with graphene-infused nanoparticles suspended in water, to improve performance. In concentrated solar thermal (CST) energy collection using parabolic trough-shaped mirrors, the heat from the sun …
Result of a 3D-Printed solar receiver of honeycomb mesh shows the heat distribution through the tubes carrying the air that acts as heat transfer fluid IMAGE©OmarBehar, KAUST A 3D-Printed solar receiver could solve some problems holding back a new technology: High-temperature solar receivers – for solar thermochemistry and industrial heat – can be prone to …

High-temperature liquid sodium receivers able to run at over 700°C may allow use of modular multi-tower system configurations similar to that being developed by the Australian firm Vast Solar (now Vast) for next-generation sodium-based concentrating solar power (CSP). Unlike today’s one tall central tower encircled by one large heliostat field, a liquid sodium-based CSP system …
Heat from solar for a hydrogen production system working like a conveyor belt MIT’s Heat-based solar hydrogen from a train of solar reactors boasts 70% heat recovery and heat-to-hydrogen from 10% to 40% In solar reactors that use solar-heated thermo-chemistry to produce hydrogen from water, heat recovery is needed to increase efficiency and, thus, lower …

NREL ETES long-duration thermal energy storage – IMAGE ©NREL Four years ago, researchers at the National Renewable Energy Laboratory (NREL) won Department of Energy (DOE) ARPA-E funding to invent a new long-duration thermal energy storage technology able to discharge heat or power for 100 hours. The goal was to devise long-duration storage with a storage …

IRA incentives for thermal storage in idle oil wells IMAGE©Geo2Watts Climate policy in the US Inflation Reduction Act (IRA) provides powerful incentives to generate renewable energy and phase out fossil fuel production. Oil and gas companies are already required to cap boreholes when an oil well is depleted, to meet Asset Retirement Obligations (ARO). But …
