Serious question for all atmospheric carbon capture companies:
What happens once you're super successful and atmospheric carbon densities are dramatically lower? Is there a point at which the density is too low for the economics to work?
Would be an awesome problem to have.
- achenatx 5y agowe burn the generated fuel and cycle the carbon again. The fuel essentially acts like a battery. You would have to use renewable energy to power the capture.
- earksiinni 5y agoDuh! Obviously (headdesk :-) I guess I was thinking more of CCS, but for fuel it makes total sense.
- alexose 5y agoI can't wait for that to be a problem :) Most carbon capture schemes like this tend to have some sort of concentration step, often using amine sorbents or other chemical equivalents. The atmospheric concentration doesn't tend to be the bottleneck here, from what I can tell. There is the question of "what happens when we're at pre-industrial carbon levels", which yeah, means that we'll have to stop getting our carbon straight from the atmosphere :)
