Fifty-four years of operating records from one of Europe's largest independent underground energy storage sites: 75 active salt caverns at Etzel in East Frisia on the North German energy hub beside the Wilhelmshaven deep-water port, with roughly 40 million cubic metres of geometric volume — about 11 million cubic metres of crude oil across 24 caverns and natural gas across 51 caverns under long-term contracts running into the 2040s, with permits already in place for expansion to 99 cavern locations. The record set comprises cavern-by-cavern leach-creation and geometry data, brine-craft and well-integrity engineering logs, cycle-by-cycle inject-and-withdraw operational telemetry, lease and capacity-contract records for a customer base of energy trading houses and European stockpiling organisations — the site holds part of the German, Belgian and Dutch national stockholding obligations — permitting dossiers under German mining law, and a documented conversion history of former oil caverns converted to gas storage, now being extended to hydrogen and synthetic methane.
