If we get serious about producing biochar, we could sequester many gigatons every year of atmospheric carbon in biochar for addition to the soil. There, it would remain stable for thousands of years and improve soil microbiology, increase soil moisture and plant growth, which in turn would provide more feedstock for additional biochar in addition to other valuable things like food.

- Faaak 3y agoOn top of that, some companies are studying adding biochar to concrete (replacing some cement). It's really interesting because it lowers CO₂ emissions twice (cement creation + biochar CO₂ sequestration). It's starting to be tested a bit in France. Take a look in google scholar because it's really interesting and will be big IMHO
