Compressed air energy storage enhanced by gravity
Scientists in China have simulated an advanced adiabatic compressed air energy storage, to which they added an elastic airbag with a heavy load situated above it. The energy, exergy, and economic analysis of the system showed that, due to the constant weight of the heavy load, the airbag’s pressure level remains unaltered during operation.

Researchers discover method to significantly extend quantum battery lifespan
Researchers at the Royal Melbourne Institute of Technology (RMIT University) and Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) have developed a way to extend the lifetime of Dicke quantum batteries by up to 1,000 times, while maintaining their fast-charging properties enabled by superradiance.
“Grid-forming technology is no longer experimental – it’s here and working”
In grids increasingly dominated by renewables, grid-forming technology is emerging as critical tool for maintaining stability and ensuring reliable power system operation. In this interview with ESS News, Rui Sun, Sungrow’s Deputy General Manager-Grid Technology Center, explains how grid-forming works, why it matters, and where the technology is already proving its value. He elaborates on technical challenges, regulatory gaps, and why grid-forming could soon become the new industry standard.
