About
Carbon Lockdown Project is a US public benefit corporation founded by University of Maryland professor Dr. Ning Zeng that develops engineered “Wood Vaults” for durable biomass burial carbon removal. Its flagship Potomac Project in Maryland targets 5,000 tCO2e of buried woody biomass under the Puro.earth Terrestrial Storage of Biomass methodology, and the company made a first 1,000-ton sale to Kinnevik in 2023. The wood burial method is designed to keep carbon stored for 1,000+ years under anaerobic conditions.
