About
Tau Carbon was founded by John Lin and Dr. Amber Janda, who developed the idea of removing CO₂ from the atmosphere by stopping the decomposition of wood while researching CO₂-to-fuels catalysts at Stanford. The California-based company stores wood biomass aboveground in modular, stackable containers, claiming a 25-meter stack can store 100,000 dry tonnes of wood waste (equivalent to 180,000 tonnes of CO2) on 2.5 acres. The firm sells credits under Puro.earth’s Terrestrial Storage of Biomass methodology.
