At each of the three towers at Ivanpah, heat from mirrors concentrating sunlight is focused up to a solar receiver. Water transfers the heat to a steam cycle power block at each base. PG&E has moved to cut short its 25 year contract with the Ivanpah tower solar project, which comprises three Concentrated Solar Power …

Atmospheric aerosols affect the generation from solar tower plants like the 100 MW Tower CSP project, Jinta ZhongGuang was originally planned by the largest renewable energy firm in the world, Three Gorges Renewables, that built the 22 GW Three Gorges Dam. Cosin Solar bought the project from them after they failed to meet a milestone, …

ETH-Zurich, IMDEA Energy, and Synhelion have demonstrated solar syngas production in a solar tower with high efficiency and selectivity Renewable energy – for electricity – can now easily and cheaply replace fossil fuels for electricity, however producing liquid transportation fuels like gasoline and aviation fuel using solar energy remains a challenge. Sustainable drop-in fuels are …

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 …
