If you burn renewable fuels (e.g. biomass) and capture and sequester the carbon, it is a net negative. (Remember the biochar concept?)

However, if we go to capturing atmospheric CO[font size="1"]₂[/font] (which I believe we may have to) we’ll need some way(s) to store it.

Right, much better to do nothing. OKIsItJustMe Aug 2013 #4

Actually, I think it is. GliderGuider Aug 2013 #6

And, if there were a chance that the band-aid would help, even a slight chance? OKIsItJustMe Aug 2013 #7

No, I'd go and do something else with my energy. GliderGuider Aug 2013 #8

CCS had better be on the menu OKIsItJustMe Aug 2013 #11

CCS won't help that. It's designed to work with concentrated CO2 collected at source IIRC. GliderGuider Aug 2013 #12

CCS actually can help reduce carbon OKIsItJustMe Aug 2013 #13

Good luck with it. GliderGuider Aug 2013 #14

We would need 15,000,000 similar storage units to store the equivalent of 1 PPM CO2 wtmusic Aug 2013 #15

Well, we might suspect it is your math that is at fault OKIsItJustMe Aug 2013 #16
