New underground wells could store carbon dioxide pollution for Microsoft and Amazon

The plan is to capture and store carbon dioxide emissions deep underground.

Oxy is building a massive industrial plant called Stratos to filter CO2 out of the air in Ector County, Texas, where the three proposed wells are located. If the project makes it to the finish line, these wells could be a key piece of companies’ efforts to hit sustainability goals, even as their greenhouse gas emissions continue to grow. Oxy has agreed to sell 500,000 metric tons of carbon dioxide removal credits to Microsoft over six years, amounting to the largest such agreement of its kind yet, according to the announcement made in July.
