Reply to comment by DukeLukeivi in Italian startup Energy Dome claims its CO2 grid storage batteries are cheaper than lithium-ion, and need no rare minerals, being made from just off-the-shelf steel components, water & CO2. It's opening its first 200 MWh facility in Sardinia in 2023 by lughnasadh

Because I doubt that a more complex system that requires extreme cold, and excess thermal energy and the storage of both will have both efficiency and cost advantages over a similar, less complex system that can function at ambient temperatures.

As this is a battery, it would be a one time carbon capture energy price, and then would be a form of sequestering it. It wouldn't be a constant input.

And until both are proven in the real world, where both are currently in the process of doing so. I don't think claiming one is so much better that the other has no use is warranted.

That is a better analogy than hybrids. Still don't think it's very applicable based on what I've seen.
