Could waste brine from desalination plants help make steel greener?
At Perth's Curtin University in Western Australia, Lina Hockaday is leading a team researching the use of waste brine to upgrade iron ore in a different way, so it can be used to make green steel. Right now, most of Western Australia’s Pilbara region iron ore is...
SolarPACES has now mapped all 43 of China’s new CSP projects
The new SolarPACES-CSTA database of all current CSP in China map enables a visualization of the locations of all 43 of China's concentrated solar power (CSP) projects that are operating or under construction by mid 2026. In China, CSP always includes thermal energy...
China General Nuclear (CGN) proposes first 100 MW Tower CSP in Brazil

China Energy’s first Tower CSP joins two by PowerChina at Talatan
Source:CSTA [CSTA News we missed from January 2026:Ed] On 29 December, China Energy's first tower concentrating solar power (CSP) project—the 100 MW Qingyu HVDC Phase-II plant of Qinghai Gonghe Co.—was successfully synchronized to the grid. The plant is the group's...
Published at Energy Conversion and Management – Short-term optimal scheduling of a cascade hydropower-wind-photovoltaic-concentrated solar power hybrid power system considering dynamic frequency security constraints and flexible load response
Abstract: As the penetration of renewable energy sources such as wind and photovoltaic generation continues to rise, the inherent randomness and intermittency of their output pose significant challenges to system frequency stability. To address the limited frequency...
Published at Renewable and Sustainable Energy Reviews – Heliostat aiming strategies in concentrated solar power towers: A review
Abstract: In conventional solar power tower (SPT) systems, heliostats typically aim at a single point on the receiver, such as the cavity aperture center or external receiver equator. While these traditional strategies minimize spillage losses, they often cause...
Published at Solar Energy – Comprehensive assessment of metrology techniques for heliostat efficiency and performance evaluation
Abstract: Concentrating solar power plants, specifically central receiver type systems and their heliostat field, are struggling with negative reputation in the USA, due to perceived underperformance and reliability issues. This is in part due to a lack of standards...
Dongfang delivers heliostats for the highest altitude CSP Project in Tibet
On April 30, a major milestone was achieved at the world’s highest-altitude concentrated solar power (CSP) tower project—the Tushuo 100 MW CSP plant in Amdo County, Tibet—where all 15,927 heliostats manufactured by Dongfang Boiler have been successfully delivered. As...
Tower CSP at Tangshan Haitai’s massive solar park runs a record 96 hours straight
During a trial run in April, 2026, one of the most recent new CSP projects in China, the 100MW tower CSP project at Tangshan Haitai's 1 GW Qiquanhu PV Industrial Park, set an operation record. It ran continuously and safely around the clock for 96 hours straight, with...

Solar experts offer a solution to satisfy both sides in Ivanpah decommissioning battle
Two California electric utilities have moved to exit long-term contracts to buy power from Ivanpah, a unique first-of-its-kind utility-scale solar tower project that has delivered only around 70–80% of its projected annual generation since it began operating in 2014....
Published at the Journal for Energy Storage – Improving the thermal energy storage performance of calcium hydride via vacancy defects for next-generation concentrating solar power
Abstract: Although the metal hydride CaH2 possesses a remarkably high hydrogen-based energy storage density, its application in thermal energy storage systems for next-generation concentrated solar power plants presents a challenge due to its 1100 °C decomposition...
Producing synthetic fuels at fossil fuel prices: a game changer from Synhelion
Source: Synhelion Liquid fuels remain indispensable for long-haul transportation in aviation, shipping, and heavy-duty road freight, because of their unmatched energy density. Today, fossil fuels power global transportation, accounting for roughly 15% of worldwide...
Tibet inaugurates a true hybrid CSP and PV project on top of the world
CSTA April 6, 2026: CGN has broken ground on the 50 MW concentrated solar power (CSP) project at Wumatang township in Dangxiong County near Lhasa, Tibet. At about 4,550 meters above sea level, it will be the highest‑altitude parabolic trough CSP plant in the world....
How big can a single tank to store molten salts be?
Replacing the standard two‑tank molten salt system with a single tank using a thermocline could cut capital costs and halve thermal tank losses in concentrated solar power (CSP) plants. But how big can a single tank safely be built when hot and cold molten salts share...
Why Chile is ideal for deploying the solar sulfur cycle for green copper
Performing the solar hybrid sulfur cycle right at the copper smelter could generate the oxygen and hydrogen to make the copper industry green Northern Chile is known for having the best solar resource in the world for concentrated solar thermal (CST). And this region...
With Spring, construction resumes at SUPCON’s 350MW triple-tower CSP in Qinghai
