You can't get more carbon out of an acre that way than you could by using that acre to produce biofuel and use that to displace fossil fuel production. We don't have enough acres of arable land to sustain our current civilization's energy consumption that way, so I think this wouldn't actually solve the problem. Though replacing mono-culture farmland with forests is nice from a biodiversity and aesthetic standpoint.
- adrianN 8y agoYou assume that the crop -> biofuel process is as efficient as the crop -> biochar process.
- Symmetry 8y agoYes, is there any reason to think that there'll be more than a factor of 2 difference? Fossil fuels will tend to have a higher hydrogen to carbon ratio than charcoal but the energy per carbon isn't that different. https://en.wikipedia.org/wiki/Emission_intensity https://en.wikipedia.org/wiki/Emission_intensity
