Greg, I don't see anyone answering your question directly here. "Carbon negative biofuel" on the Cool Planet model means producing market-ready gasoline from biomass, with a proprietary fractionating technology analogous to what is done with crude oil. That in itself is not carbon-negative since combusting the gasoline will produce CO2, but there is a byproduct biochar stream which can be adjusted to a larger or smaller component of throughput; to the degree that biochar is sequestered in soil it effectively removes CO2 from the atmosphere, and also substitutes C from the biosphere for C that would otherwise be mined from fossil sources.
