Occidental Petroleum (Occidental) and its subsidiary 1PointFive have secured Class VI permits from the US Environmental Protection Agency for the STRATOS direct air capture (DAC) facility in Ector County, Texas.
This milestone allows Occidental to sequester carbon dioxide (CO₂) from the world’s largest DAC project, enhancing the US’ energy security and economic growth in Texas.
The permits, issued under the Safe Drinking Water Act’s Underground Injection Control programme, are crucial for Occidental’s plan to securely store CO₂ captured from the atmosphere.
Occidental demonstrated compliance with federal and state requirements for injection wells storing CO₂ in geologic formations more than one mile underground.
Occidental Petroleum president and chief executive officer Vicki Hollub said: “This is a significant milestone for the company as we are continuing to develop vital infrastructure that will help the United States achieve energy security.
“The permits are a catalyst to unlock value from carbon dioxide and advance direct air capture technology as a solution to help organisations address their emissions or produce vital resources and fuels.”
