About
South Ocean Air is a Houston, Texas-based direct air capture startup founded in 2023 that uses plasma-treated cellulose as a passive sorbent to capture CO2 from ambient air. The company remains small and pre-commercial, targeting low-cost modular DAC units, and is still seeking investors and early customers.
