Anyone know why you would need to store CO2 and not just regular air in this case?

  In the article: "Spadacini explains that Energy Dome uses CO2 because it can be converted into liquid under pressure at 30°C, compared to minus 150°C for air. Highview Power’s liquid-air battery therefore has to use cryogenic technology to liquefy air, but the Energy Dome system requires far less power, resulting in cheaper costs and a higher round-trip efficiency, the company says."
