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. [1] https://www.youtube.com/watch?v=cOWjwwKSR78 https://www.youtube.com/watch?v=cOWjwwKSR78
