Hamed Sanei, expert in geoscience, discusses the stability of carbon storage in biochar. Recent research shows biochar's effectiveness as a durable carbon removal method. It represents 92% of sales and has the potential to deliver three gigatons of CDR annually. Biochar is thousands of years old, works as a soil amendment, and can be made from various biomass types. The debate over carbon storage permanence needs to be closed so the biochar community can focus on its potential.
