# Direct Air Capture in Texas

#### Texas Leads the Way on Direct Air Capture in the Permian Basin

In 2019 Occidental became one of the first major oil companies to invest in developing direct air capture (DAC) factories. The company invested in Carbon Engineering, a Canadian business that developed a DAC pilot plant outside of Vancouver. Together, the companies have begun the engineering and design work of the world’s largest DAC and sequestration facility, located in the Permian Basin with a land footprint of approximately 100 acres, rumored to be in Ector County (home of Odessa). Construction on the facility is expected to start in 2022 with the possibility of creating 1,000 jobs.1Globe Newswire.

When operational, the facility will be the largest DAC plant in the world, capturing up to one Mt of atmospheric CO2 annually. Currently, the world’s largest individual DAC facilities have the capacity to capture several thousand tonnes of CO2 per year. The CO2 captured (500,000 t/yr) at the facility will be stored by Occidental in the subsurface using two methods. First, Occidental will use the CO2 as part of their enhanced recovery program in the Permian. The company uses 50 Mt of CO2 annually for enhanced recovery, which permanently stores CO2 as part of the process. Second, geologic sequestration will deliver permanent CO2 removal. Occidental plans to use these two methods to help achieve their ultimate goal: to put more CO2 into the ground than it takes out in the form of fossil fuels. Partnerships on commercial development of DAC facilities has been made possible by market-based policies in the U.S., such as the California Low Carbon Fuel Standard and Federal 45Q tax credit.3Globe Newswire.

## Ethanol production

#### Correct.

An industrial process such as ethanol production produces highly concentrated CO2 streams. Average costs are \$15-25/t.

## Cement production

#### Incorrect.

Gas streams from cement production produce more dilute CO2 streams.
