The largest U.S. federal loan guarantee for long-duration energy storage didn’t last long. Less than two weeks after the U.S.

Compressed Air Energy Storage (CAES) systems offer a promising approach to addressing the intermittency of renewable energy sources by utilising excess electrical power to compress air that is stored ...

These low-tech systems offer cheap, long-duration storage with minimal degradation, using abundant materials and basic ...

Researchers in China have investigated the long-term stability of horizontally connected salt caverns used for compressed air energy storage. They found about 85% of the existing salt caverns in their ...

Scientists in China have simulated a system that combines liquid-based direct air capture with diabatic compressed air energy storage, for the benefit of both processes. Exploring its economic ...

Iron-air batteries use a reversible rusting process to store and release electricity using abundant materials like iron and water. These “100-hour batteries” could solve renewable energy’s biggest ...
