Carbon America focuses on capturing carbon dioxide (CO2) from ethanol facilities for sequestration. The company finances, builds, owns, and operates carbon capture and sequestration (CCS) systems. The captured carbon is transported via an underground distribution pipeline to a permanent geological storage site, over 4,000 feet underground. In January 2024, Carbon America submitted an application to the Environmental Protection Agency for permission to build and operate an underground CO2 injection well named “Denova” in Colorado.
Carbon America is developing their FrostCC cryogenic CO2 separation technology, a scalable and low-cost solution that can be applied across industries without using added chemicals or water. The FrostCC process self-refrigerates the flue gas through compression and expansion, allowing it to freeze and capture the CO2 as a liquid product. In March 2024, the company commenced the testing of the FrostCC technology at the National Carbon Capture Center to validate its performance and enable scaling up the technology.
Key customers and partnerships
In May 2022 , the company announced two agreements with Sterling Ethanol and Yuma Ethanol to develop two commercial CCS projects at Colorado ethanol production facilities to capture 95% of CO2 emissions and to permanently sequester CO2, nearly one mile underground in northeastern Colorado. In October 2022 , Carbon America entered into a strategic partnership with chemical producer Bridgeport Ethanol to launch its first commercial CCS project in Nebraska, US. The project was expected to capture and store 175,000 tons of CO2 per annum, with plans to operationalize in 2025.
In May 2023 , the company teamed up with Svante to deploy commercial CCUS projects in the US.
