David: cc List
I agree that DAC is not likely a good choice for a few years - but
there are hundreds of companies producing biochar today with a good bit of hot
CO2 release. Most has to be thought of as essentially free. And the gas is
carbon neutral - with hopes of increasing the overall carbon negativity of the
process. Check the IBI website for some of the companies involved.
On Oct 8-10 you could attend a meeting in Stockholm discussing that
city’s biochar production (and maybe CO2 release). I think this is running
without subsidy.
