    It’s poor for the second, since the result is a gas (hard to store long term). We would want it as a solid or liquid product, which this doesn’t do.

    Why wouldn’t the device include or feed a compressor to liquidize the CO2? It takes just a little over 5 atm of pressure which is trivial.

      You also need to sustain 5 atm, with no leaks for years. Where is it being stored, and who’s paying for the maintenance? All it would take would be a bit of civil unrest, or corruption, and the work could be undone in mass.
