Occidental Petroleum Corp. subsidiary 1PointFive signed an oxygen supply contract with Nippon Sanso Holdings Corp.’s US operating company Matheson Tri-Gas Inc. for the carbon capture, utilization, and sequestration company’s first direct air capture (DAC) plant in Texas’ Permian basin.
Matheson will invest in and establish an air separation unit to supply oxygen to Stratos, the plant under construction in Ector County. The oxygen is used to produce a pure stream of CO2 which is then sequestered in geologic reservoirs, the service provider said.
Stratos is expected to begin operations in mid-2025 and capture up to 500,000 tonnes/year (tpy) of CO2 when fully operational. The first stage of construction, which includes site preparation and road work, has begun. Stratos will be scalable to 1 million tpy if demand warrants (OGJ Online, Aug. 25, 2022).
The technology that 1PointFive will utilize is one developed by Carbon Engineering of Canada, which absorbs CO2 from the air using potassium hydroxide (KOH) solution.
The company has advanced product sales for the plant, including carbon removal credit purchases from Airbus, Shopify, and ThermoFisher.
