TL;DR

Biochar as durable carbon removal on-farm: 1 tonne biomass → ~1/3 biochar, 2/3 syngas. Useful mass-balance framing rarely stated so plainly.
Guest cites ~2.7 tCO₂e sequestered per tonne of biochar (80% carbon). Standard figure, worth internalizing.
Claim: biochar is currently the largest deployed carbon sequestration method. Defensible on delivered durable tonnes today, but worth checking against CDR.fyi.
Own-farm data: soil carbon doubled in top 100mm over 10 years including through the 2019-20 drought. Anecdotal, single site, no control — treat as directional.
Economics hinge on monetizing the syngas, not the char. This is the real CDR-relevant insight.

Australian ag podcast Ground Cover (host Pippa Jones) interviews John Winter, a chemical engineer turned Glen Innes cattle producer and inventor behind SEATA Group’s pyrolysis pilot. The episode is pitched at farmers, but there’s enough on unit economics and durability accounting to make it worth 45 minutes for a CDR practitioner working on biomass pathways.
