Distributed CO2 capture + distributed hydrogen production = distributed fuel production? - C2V - CO2 to Value In fact - CLIMAX
Companies such as Carbon Engineering are pioneering CO2 capture mechanisms that could work on small scales, offering the promise of these working at decentralized locations where the CO2 is emitted, and these could even be small breweries for instance.
In parallel, there are also efforts to make decentralized hydrogen production through electrolysis cost effective.
If both the above could work, we have the tantalizing possibility of combining hydrogen and CO2 at distributed locations and converting them into liquid fuels, providing the electrochemical or thermochemical mechanisms for such conversion could also work econimically on small scales.
