What the tool says on this profile
Engineering review, not a catalogue answer. CAES compression is an air duty at utility scale — outside this site's process-gas catalogue, which starts where plant-air machines stop. Multi-stage centrifugal trains with intercooling dominate this duty; the right next step is an engineering conversation, not a pre-selection.
What to watch
- The daily charge/discharge cycle makes part-load efficiency and start frequency the real selection drivers.
- Cavern storage runs at tens of bar; salt-cavern projects in China now publish operating pressure ranges worth checking against.
- Heat recovery from intercooling is where CAES round-trip efficiency is won or lost — it belongs in the duty specification.
