Aemetis

Aemetis is developing its CCS at its Riverbank biorefinery in California to capture CO₂ generated from renewable fuel and biogas production processes. In 2020, Aemetis partnered with Messer Gas to capture more than 150,000 tonnes per year of CO₂ from the Keyes ethanol facility into liquefied CO₂ for food and beverage markets. The company is now expanding its capture system to support significantly higher volumes and transition from merchant CO₂ sales toward permanent sequestration. The system is designed to allow Aemetis to sequester approximately 400,000 metric tonnes of CO₂ per year from its own operations and up to an additional 2 million metric tonnes per year from third-party fuel producers in the surrounding region. Captured CO₂ will be dehydrated, compressed to pipeline specifications, and routed to nearby storage infrastructure being developed as part of the Riverbank CCS hub.
