Carbon Cantonne (Accelerator)

Company Description: Carbon Cantonne empowers carbon removal to utilize novel net-negative CO2 solutions that accelerate the return of clean air. Cantonne’s technology takes concentrated CO2 from capture sources, like air or exhaust gas, and turns it into marketable graphite that can be used for lithium batteries and reinforced concrete. Our unique approach minimizes the need for external power sources due to the large heat produced by the reaction, which is recycled for heating internal processes with plenty of excess heat to supply to capture operations. A megatonne/year scale plant can convert captured CO2 into value-added product at under $10 per tonne. Cantonne was founded in November 2021 by researchers at the University of Calgary with a passion for CCUS research. Our team entered into the XPRIZE Carbon Removal competition and reached the Top 50 out of over 1100 contestants in the first milestone round.
