"Although bioenergy-biochar systems (BEBCS) can also deliver CDR, they are not included in any IPCC scenario. Here we show that despite BECCS offering twice the carbon sequestration and bioenergy per unit biomass, BEBCS may allow earlier deployment of CDR at lower carbon prices when long-term improvements in soil fertility offset biochar production costs."

"Biochar is a fascinating carbon-negative technology.  It is created through the burning of biomass feedstocks (wood, crop wastes, manure, etc.) in low or no oxygen conditions; this oxygen-deprived process is called pyrolysis.  Biochar acts as a carbon sequestration technology by storing the carbon dioxide absorbed by plants during growth within the char."

"To discuss the potential benefits and challenges of soil carbon sequestration, Le Foll spent two days with Lal at Ohio State’s C-MASC, where the discussion focused on the feasibility of the 4/1000 proposal.¹⁶ C-MASC has collaborated with the Natural Resources Conservation Service (NRCS) and Agricultural Research Service of the U.S. Department of Agriculture to conduct research on this theme since early 1990s."
