Huntorf CAES Plant (1978)
Germany built the world's first commercial compressed-air storage plant near Bremen. It stored 290 MW of off-peak power as compressed air in two salt caverns and released it to meet peak demand within minutes.
The plant proved CAES could work commercially and has supplied the northwest German grid for almost five decades.
No large-scale compressed-air plant followed for 13 years; the technology stayed niche while gas turbines were cheap.
Silver City is the first modern attempt to deploy CAES at utility scale with advanced heat recovery that Huntorf lacked.
