SolarPACES

SolarPACES.org is a global community of researchers focused on concentrating solar power (CSP), which is a type of solar energy that can be delivered when needed thanks to its thermal energy storage capabilities. Established in 1977, this organization is now playing a key role in advancing high-temperature concentrating solar thermal (CST) technologies. These innovations aim to reduce carbon emissions in various industries, including cement production, and enable solar thermochemistry for generating solar fuels.

Source: CSTA On the evening of May 10, the Tibet Zabuye 40MW CSP project, undertaken by Shandong Electric Power Construction Company No. 3, a CSTA member, achieved simultaneous heat storage and power generation with two sets of molten salt, signifying full operation. Located on the southeast side of Zabuye Salt Lake, 165 km north of Zhongba County, Rikaze City, at an altitude of over 4,500 meters, this project is the world’s first high-altitude, grid-end one.
Optimizing the safety factor in high temperature solar absorbers

Nearly all the Tower-type Concentrated Solar Power (CSP) plants in operation use molten salts to transfer heat to produce electricity. This thermal form of solar energy has value because it incorporates stored thermal energy, which enables grid benefits like rolling reserves.
Published at Energy - Optimization on thermal performance of the cavity-shaped porous solar receivers

1 week ago | solarpaces.org | Susan Kraemer

Abstract:This study investigates the thermal performance of cavity-shaped porous solar receivers (C-PSR) designed to reduce peak solid temperature and re-radiation losses by optimizing the matching between the heat transfer fluid mass velocity and concentrated solar flux. In this study, a C-PSR prototype was fabricated and evaluated on an indoor sun simulator platform to validate the heat transfer model.

Abstract:An experimental and computational research was performed to explore the augmentation of turbulent convection in a solar receiver channel by utilizing louver-punched V-type winglets (LPVWs) that were fixed to the absorber plate. The simulation utilized the realizable k-ε turbulent model, and the predicated outputs were verified by the relevant measured data. At a fixed attack angle (α) of 45°, the LPVW components were mounted on the absorber with the V-tip facing downstream.

Abstract:Volume-averaging method constitutes an efficacious approach for analyzing and optimizing the overall efficiency of the porous receivers. However, the accuracy in the prediction of heat transfer process is significantly contingent upon the precise assessment of empirical parameters. The comprehensive parametric study of empirical parameters and solar radiation uniformity is conducted by applying volume-averaging method in conjunction with local thermal non-equilibrium model.

This striking concrete structure, accompanied by more than 130 mirrors positioned alongside it, is part of the world’s first supercritical carbon dioxide solar thermal power generation system.
Finding an ideal channel geometry inside compact flow gas receivers

2 weeks ago | solarpaces.org | Susan Kraemer

In concentrated solar power (CSP), how well the working fluid transfers heat through a receiver can make or break system efficiency. For solar-heated thermochemistry, solar receivers need to operate at very high temperatures, up to 1400°C. Gases like air are cheap, nontoxic, and have no temperature limitations, so researchers are working on gas-based solar receivers that move heated gases like air, helium, or nitrogen.
As the US Cuts Scientific Talent, Europe Launches an Initiative to Attract It

Source: WiredThe European Commission has launched a new initiative to attract researchers and scientists to the European Union—especially those from the United States. The Choose Europe for Science program, backed with more than half a billion dollars, is designed to offer an alternative to researchers who have been forced to seek new opportunities following cuts in scientific funding imposed by President Donald Trump’s administration.
