Why Occidental Petroleum quietly bets on direct air capture with Stratos 1

With the Stratos 1 direct air capture plant, Occidental Petroleum wants to turn a dusty patch of West Texas into a carbon vacuum cleaner that can filter up to 500,000 tons of CO? from the atmosphere each year. The project feels more like a tech startup campus than a conventional oilfield. Pipes, fans, modular units - and a promise that goes far beyond drilling.

What Stratos 1 is supposed to do

Stratos 1 is being built near Notrees in the Permian Basin and is designed as one of the world's largest direct air capture plants, with a planned capacity of up to 500,000 tons of CO? removal per year once fully ramped. The plant will use large fans and chemical sorbents to bind CO? from ambient air, then compress and either store it underground or sell it as a feedstock for products and enhanced oil recovery.

Occidental Petroleum, via its subsidiary 1PointFive, markets Stratos 1 as a scalable blueprint - a kind of industrial kit that can be replicated on other sites. The modular layout with repeated capture units should make later expansions faster and cheaper than a one-off mega build.

How the capture technology works in practice

Technically, Stratos 1 relies on direct air capture technology licensed from Carbon Engineering, a Canadian specialist Occidental agreed to acquire to secure long-term access to the process. Air passes through contactor units where liquid or solid sorbents selectively absorb CO?, which is then released again by heating or pressure changes before being dried and compressed.

Compared with point-source capture on chimneys, direct air capture deals with far lower CO? concentrations and needs more energy per ton. The attraction is flexibility: plants like Stratos 1 can be sited where low-carbon power and suitable geological storage are available, independent of specific emitters.

Customers, credits and business model

Occidental is not building Stratos 1 on spec. The company has already signed agreements with corporate customers such as Airbus and others for removal credits from future plants, positioning the output as a premium climate service rather than a commodity. In the US, generous tax incentives for carbon capture and storage under the 45Q scheme further support the economics by paying a fixed amount per stored ton of CO?.

The business model combines several revenue streams: long-term offtake agreements for verified CO? removals, tax credits, and potential use of captured CO? in materials or low-carbon fuels. For investors, the big question is whether costs per ton can fall quickly enough to turn large-scale DAC into a profitable line rather than a permanent subsidy project.

Where the project still raises questions

Energy demand remains the weak point. A plant designed for hundreds of thousands of tons a year needs a substantial amount of low-carbon power; Occidental has highlighted the role of renewables and potentially low-carbon electricity in its plans for Stratos 1. If that power mix is not clean enough or too expensive, the climate benefit and economics quickly erode.

Verification and trust are another challenge. Customers paying for removal credits want robust measurement, reporting and third-party certification. That means continuous monitoring of capture volumes, storage integrity and potential leakage over decades - a level of documentation more familiar to regulators than to traditional oilfield operations.

How Stratos 1 fits into Occidental's strategy

Occidental bundles Stratos 1 and planned follow-on projects into a broader "carbon management" strategy, which includes CO? pipelines, sequestration hubs and services for industrial emitters. The company openly links this to its ambition of reaching net-zero for its own operations and providing so-called "net-zero oil" to customers.

For an oil and gas producer, that is a tightrope walk. On the one hand, DAC plants and storage hubs open up a new service business that could soften long-term demand risk. On the other hand, environmental groups criticize the idea of using captured CO? for enhanced oil recovery, arguing that this extends fossil fuel use instead of cutting it.

Context and stock reference

In sum, Stratos 1 is a technically ambitious, capital-intensive bet that Occidental Petroleum hopes will secure it a leading position in engineered carbon removal while still monetizing its subsurface expertise. Shares of Occidental Petroleum (US6745991058) recently traded on the NYSE around the low-50-dollar range per share.
