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 …

Abstract: The use of solid particles as direct heat absorbance and storage media promises enhanced storage densities in concentrated solar power (CSP) technologies. The long-term optical performance of those particles, which aim to be operational over years, is crucial. Dry powder coating with a deep black Cu-Mn-oxide pigment in a resonant acoustic mixer and subsequent …
Erosion wear analysis of heat exchange surfaces in a falling particle-based concentrating solar power system Abstract: Next generation concentrating solar power (CSP) plants that use solid particles as the heat transfer and storage medium provide opportunities for higher temperature operation, higher efficiency, and lower levelized cost. However, falling particles over component material surfaces can cause …
Abstract: The cost-saving potential of next-generation concentrating solar power plants based on particle technology with steam cycles is assessed. Techno-economic models were created to optimize three systems with different steam cycles, ranging from state of the art to future development, for levelized cost of electricity and to compare them to a state-of-the-art molten salt tower …
29th SolarPACES Conference 2023 Technical Tour Australia Tour the pilot-scale sodium receiver and falling curtain particle receiver in Australia During the 29th SolarPACES Conference, a day trip from Sydney will take you on a Technical Tour of the CSIRO National Solar Energy Centre at Newcastle, where the working of two gen-3 receivers will be demonstrated: …

Clean solar energy with storage can help Europe reduce emissions and deliver a secure and cost-effective electricity supply. EU-funded research suggests that fluidised crystal particles trump molten salts as the heat transfer and storage medium. © Gilles Flamant Current state of the art concentrated solar power (CSP) plants use central receivers with several options for …
