    I work in electricity and heat production, to me this sounds mainly green washing. Why use CO2 and plain pressure?

    Storing this magical 200MWh, would require stupid amount of volume and pressure. We have better gasses, and hundreds of years on knowledge in heat pump tech with better efficiencies.

    To my ear it sounds that they just picked CO2 for news articles/investors, not for science reasons.
