China Grid-Connects 60 MW Liquid Air Energy Storage Demonstration Project

Liquid air storage has long been framed as a promising but unproven long-duration option, so a grid-connected national demonstration at this scale matters less for the megawatts than for the operating data it will generate on round-trip efficiency and cycling. The project sits in a province rich in renewables, which makes it a test of whether storage can ease curtailment rather than simply add capacity. Whether the demonstrated performance supports broader commercial replication, and how the cooling co-output is valued, are the open questions worth watching.
