A 60-MW liquid-air energy-storage project in Golmud, Qinghai, connected to the grid and began generating electricity.

A CCTV report relayed through Financial_Express says a 60-megawatt liquid-air energy-storage demonstration project in Golmud, Qinghai, successfully connected to the grid and began generating electricity. The report, citing China Green Development Investment Group, describes it as the world’s largest project of its type.

The installation uses air as its working medium and a −194°C cryogenic liquefaction process. The report describes storage and release of electrical and cold energy under atmospheric-pressure, ultra-low-temperature conditions.

The stated capability is to support absorption of 600,000 kilowatt-hours of clean electricity per day, with approximately 180 million kilowatt-hours of annual electricity transmission, described as sufficient for 30,000 households’ annual consumption. These are reported capability and annual-output figures, not a demonstrated full-year operating record; the 60-MW figure denotes power rather than stored energy.
