On their website (energydome.com) they claim “75%+” round trip efficiency, so not a bad guess!

That’s a hell of a lot better than most other systems. If true, and if scalable, this is a huge innovation.

Compressed air without heat recovery is more like 30%, so this is huge Carbon dioxide can be liquefied relatively easily which is what i guess makes this efficient

I was just about to bang out that they must lose a lot of heat from the compression. But apparently not! That’s amazing. I’m struggling to think of systems that would significantly outperform “75%+”. Chilled superconducting coils? Those are expensive, and would fail rather catastrophically.
