Tsinghua Study: Biochar on Abandoned Cropland Could Be CDR's Cheapest Path in China
🌍 From China: biochar’s biggest limitation might have a cleaner solution than anyone expected. New research from Tsinghua University identifies an approach that could simultaneously solve biochar’s biomass supply problem and make it one of the lowest-cost CDR pathways available: growing bioenergy crops on China’s abandoned agricultural land and converting them to biochar. The numbers are significant. The research estimates this approach could support approximately 25.8 million tonnes of CO₂ removal per year — roughly comparable to what biochar can currently deliver using agricultural and forestry residues, which are the conventional feedstock. This isn’t a marginal improvement; it’s a doubling of the potential. ...
