While the search results do not specifically mention innovations for high-temperature thermal storage in Compressed Air Energy Storage (CAES) systems, they do highlight advancements in high-temperature thermal energy storage that could be relevant or adapted for CAES:
High-Temperature Thermal Energy Storage Innovations
- Advanced Materials:
- Graphite, Silicon, and Refractory Brick: Companies like Antora Energy, Rondo Energy, Kraftblock, and Alumina Energy are using materials such as graphite, silicon, and refractory brick to achieve high temperatures. For example, Antora Energy uses graphite to reach temperatures up to 1,500°C, while Rondo Energy uses refractory brick to achieve over 1,000°C.
- Molten Silicon: NREL’s ENDURING project utilizes molten silicon to store energy at temperatures around 1,200°C.
- Concentrating Solar Thermal Systems:
These systems provide heat during low solar availability, supporting high-temperature energy storage. - Thermochemical Energy Storage:
This method involves materials designed to operate at temperatures between 600°C and 800°C, enabling efficient thermal-to-electric power conversion. - High-Efficiency Thermal Energy Storage:
Researchers at KTH have developed a radial flow packed-bed system that achieves over 90% thermal efficiency and can store heat up to 800°C. This technology uses hot air and pebbles/copper slags.
While these innovations are not specifically for CAES, they represent significant advancements in high-temperature thermal energy storage that could be adapted or inspire similar innovations for CAES systems. Incorporating such high-temperature storage could help improve the efficiency and thermal management of CAES systems.
