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 …

Redstone, the first Tower CSP plant in South Africa is completed. This image taken August 20, 2024 shows how the solar receiver atop the tower is activated by the reflected sunlight from the solar field of heliostats (mirrors) surrounding the power block seen here below the tower: IMAGE©Xinhua (by Zhang Yudong) [Ed: Finally, the Redstone …

After the solar heat trap experiment measuring the temperature increase to 1050°C at the back of the solar receiver inside a solid block of quartz, even at the front, the temperature measured 450°C IMAGE©Solar thermal trapping at 1,000C and above. Solar receiver efficiency in concentrated solar thermal (CST) energy is determined by how much solar …

Abstract: The principal strategy for achieving a neutral climate entails enhancing the share of renewable energies in the energy mix, in conjunction with promoting innovation in efficient technologies. Thermal energy storage systems have the potential to efficiently handle the intermittent nature of renewable energy sources. Furthermore, these systems can effectively handle shifts in both heat …
CSP hybridized with MED desalination payback times A team of Australian researchers at the University of New South Wales (UNSW) has combined three tools to assess the economic viability of a hybrid CSP and desalination plant applicable for any region worldwide. “The interesting thing is you can modify this by yourself,” lead author Yingfei Huang …

Like the first samples of other new energy technologies, the first full-scale CSP tower with thermal energy storage had a shaky start The Crescent Dunes CSP project in the US was the first of a kind at 110 MW. The first tower CSP with thermal energy storage at full-scale. (Above about 150 MW, the distances …
The government of Spain is launching €280 million (US$310 million) in grants for standalone energy storage projects, thermal energy storage and reversible pumped hydro to go online in 2026. The Ministry for the Ecological Transition and the Demographic Challenge (MITECO) opened a public consultation into the grant scheme last month seeking comments on the proposal …
