200 bar is an inflection point in the regulatory landscape for above ground tanks. A sweet spot. There's another sweet spot around 300 - 400 bar due to the physics of air.
Salt caverns melt at high enough temps (above 200 C) and injecting hot air into a methane reservoir is not terribly advisable...
- dredmorbius 12y agoTook me a moment to realize you were talking CAES in salt caverns, not salt caverns for thermal energy storage, though that hadn't occurred to me either (I don't think it's necessary). The constraints you raise on natural-formation CAES do raise some interesting challenges (or Hollywood movie plots).
