World's largest liquid-air energy storage plant commissioned in China
A 60 MW / 600 MWh liquid-air energy storage facility in Qinghai province was connected to the Chinese grid — the largest operational LAES installation globally, using cryogenic liquefaction of ambient air to store electricity as thermal energy and release it via expansion turbines for 10-hour duration dispatch.
- LAES uses no critical minerals, no lithium, and no cobalt; competes with pumped hydro in siting flexibility
- Round-trip efficiency at scale now confirmed at 60-65%; prior installations ran closer to 50-55%
- 10-hour duration fills the LDES gap between Li-ion (4h typical) and pumped hydro (days)
