minus-squaresilence7@slrpnk.netlinkfedilinkarrow-up8arrow-down1·9 months agoThere’s also kind of a history of biochar requiring a bunch of energy to move biomass to the retort, heat it up, and move it back to the field. Power all that with fossil fuels, and you can very easily end up emitting more than you remove.

minus-squaresilence7@slrpnk.netlinkfedilinkarrow-up4arrow-down1·9 months agoThat’s fine. The issue comes when you try to use equipment to scale it up, and that equipment uses fossil fuels.
