I hope this can be a consumer product I could use to trickle charge my propane tanks. $33 to refill a 20lb tank is killing me.
I hope so, too, but I don't think that it will. Odds are that the process requires a higher concentration of CO₂ than just the 0.4% in atmospheric air, so this would be only viable in industrial plants - specially the ones producing steel and quicklime.
Another concern that I have is that the process likely requires hydrogen.
