According to PV=nRT (ideal gas law), no you cannot in a closed system!!! But Hydrostor isn't violating any laws of physics -- they are simply capturing that heat so that it doesn't become waste heat!
Hydrostor has a thermal management system that captures the heat and stores is during compression. Then it reuses the heat when it is decompressing the air.[1]
This seem extremely promising as a much smaller footprint solution than pumped storage and much more sustainable and lower cost than any other energy storage solution. I just heard about them today, and I'm extremely impressed.

That doesn't seem isobaric. Searching if it's possible, I've seen mentions of condensing working fluids, and bumby mentions ocean floor bags which seem like a good solution.
