Abstract: Bauxite-based proppants, commonly used in the fracking industry, are also employed in solid particle receiver types of Concentrated Solar Thermal (CST) technologies. However, fracking has been banned in many countries due to its environmental impact, leading to a decline in demand for proppants. As a result, the current proppant price of 1 €/kg is …
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 …
US solar steam projects developer GlassPoint on Tuesday announced it is advancing plans to build the world’s largest industrial solar thermal project in Saudi Arabia, unveiling the next phase of development for the GlassPoint Ma’aden Technology Showcase (GMTS). GlassPoint is developing the GMTS project with the Ministry of Investment of Saudi Arabia (MISA). The company …
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 …
Abstract: Molten salt thermal energy storage (TES) tanks ensure steady power output of concentrating solar power (CSP) plants; however, recent tank failures have highlighted the need for further analysis. Current studies primarily focus on analyzing the molten salt flow, heat transfer, and thermal efficiency. Additionally, research on the latest tank structures is limited and lacks …

Abstract Heliostat fields represent the primary energy input for concentrating solar-thermal power based on power tower technology. They typically account for 40 %–50 % of the implementation cost of a power tower plant. Therefore, it is essential to optimize the solar tracking accuracy of heliostats to reduce solar tracking errors that lead to deviations in …
Abstract: Wind loads are a major driver of heliostat cost. Standardized methods and tools are needed for a more detailed understanding of the static and dynamic loads of a heliostat design. This will enable cost reduction of wind-dependent heliostats to avoid unnecessarily conservative heliostat designs and increase field efficiency and reliability to reduce the risk …
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 …
