Major US Oil Company Now Plans World's Largest Carbon Capture Project (reuters.com) 76

If you ranked all U.S. companies by annual revenue, Occidental Petroleum comes in at #183.

But Wednesday this massive "hydrocarbon exploration" company "outlined plans to advance its clean energy transition business," reports Reuters, "including spending between $800 million and $1 billion on a facility to remove carbon dioxide (CO2) from the air." The proposed facility, the world's largest direct air capture (DAC) project, is set to begin construction in the second half of this year in the Permian basin, the largest U.S. oilfield, with a start in 2024. The U.S. oil and gas producer is aiming to build a profitable business from providing services and technologies that pull CO2 out of the air and burying it underground to advance government and business climate mitigation goals. This year's investments in the low carbon business will total $275 million, and the company plans to develop over time three carbon sequestration hubs that will be online by 2025 and another 69 smaller DAC facilities by 2035, it told investors....

Occidental's first DAC facility has a goal of removing 1 million tonnes of CO2 from the atmosphere per year — 100 times bigger than all 19 DAC plants currently operating worldwide combined, according to the International Energy Agency.

"There's just not going to be enough other alternatives for CO2 offsets," said Occidental Chief Executive Vicki Hollub. "So this is a sure opportunity." Executives did not say when they expect the business to turn a profit. DAC is currently not commercial on a large scale. "We expect that to play out over the next five to 10 years as we develop plants," Richard Jackson, Occidental's head of U.S. onshore resources and carbon management operations, told Reuters by phone. "The commerciality of those plants will be determined by mainly the market".

Last month Occidental announced that Airbus had already pre-purchased "400,000 tonnes of carbon removal credits from [Occidental's] planned first Direct Air Capture facility," specifically, "the capture and permanent sequestration of 100,000 tonnes of CO2 from the atmosphere each year for four years — with an option to secure more volume in the future."

Occidental called the deal "indicative of the availability of a feasible, affordable, and scalable decarbonization solution for aviation and other hard-to-abate industries."

    We've understood thermodynamics since the 19th century, and yet somehow we keep falling for perpetual motion machine scams. Pulling CO2 out of the atmosphere requires enormous amounts of energy, and either that means using emitting fuel sources or alternative energy sources. If it's the former, then it's an automatic fail, if it's the latter, and you're producing enough to actually power a carbon capture plant, then why would you burn fossil fuels at all?

    • by ShanghaiBill ( 739463 ) on Saturday April 23, 2022 @02:44PM (#62472286)

      You misunderstand. Occidental is not pulling CO2 out of the air to please the greenies.

      They are extracting CO2 from the air, compressing it into a supercritical fluid, and pumping it "downhole" into fracking wells.

      Super-critical liquid CO2 is 1.5 times the density of water-based fracking fluid, needs no expensive additional solvents, and is very effective at freeing hydrocarbons from shale and displacing it upward to be pumped to the surface.

      Selling the carbon credits to gullible European taxpayers is just an extra benefit.

                - Continued use of fossil fuels.

                • You missed one, solar power satellites.

                  One of the more useful metrics is how fast an energy source repays the energy used to create it. Currently solar is about a year in favorable places. Wind comes in in good places at around 6 months.

                  Solar power satellites (if they are ever built) require a lot of energy to lift them into space. But it turns out that the energy repayment is between 2 and 3 months.

                  There are other solutions, but the technology is not advance enough for them yet.

                  • You missed one, solar power satellites.

                    No, I didn't miss that. That is because this is one of those mythical fourth options that we can't use today because it doesn't exist yet. You even admit it doesn't exist yet.

          It's complicated. These are not virgin wells. They are wells that are already depleted of the "easy" oil. Then EOR is being used to get another 20% or so.

          CO2 takes up a lot more space than heptane or octane, so you can't displace carbon one-for-one. But since the wells are already mostly depleted, there is plenty of space to shove CO2 in.

          The world still relies on oil, which will continue to be true for decades. Since we need oil anyway, it makes sense to produce domestically and do it as carbon-neutrally as possible. So this is a net good thing. That European taxpayers are paying for it makes it even better.

          • Crude is very variable in its carbon content, but turns out a kg of number six bunker oil, at nearly a kg per liter (0.98 kg actually) makes 3.1 kg of carbon dioxide. Meanwhile a liter of liquid CO2 masses 1.1 kg. So roughly speaking we're pumping in 1.1 of CO2 to perhaps make 3.1 kg of CO2 upon burning the fuel.

            Yes, it's hilarious. There is green, and there is greentard. This is greentardation.

              You assume that every liter of fluid going downhole means a liter of oil coming up.

              That is wildly incorrect.

              For standard fracking fluid, about 100 liters go downhole for every liter of oil produced.

              CO2 is more effective than water-based solvents, so it will do somewhat better, but there is no way it is one-to-one.

              If it was one-to-one or even ten-to-one, every fracker in the world would be doing this.

              • Enhanced recovery isn't fracking though, has some amount of oil coming up for fluid pushed in, not the 100 to 1

        • So I wonder how much carbon they'll be pumping out of the ground per unit of carbon captured? Hope the answer is something hilarious.

          It's completely irrelevant. The carbon being pulled out of the ground is not being pulled out to make space for what is being put in, it's being pulled out because it's a product that an end user demands.

          Even if we pull 10000 units of carbon out and only put 1 unit back, that is still 1 unit less carbon that well would otherwise contribute, and if they didn't pour supercritical CO2 in there then it would be some other concoction of chemicals the industry already uses for end of life wells.

          • Wrong and utterly ignorant, devoid of basic mathematical understanding.

            The amount of carbon removed from the atmosphere is negligible and doesn't matter at all, then it's used to bring up many times that amount of carbon. It's expensive stupidity.

            Plenty of sensible alternatives exist to this project, instead of capturing carbon in a stupid cycle of pumping out many times that amount of carbon, the money could be spent on clean energy that would be used instead of carbon.

      • Use the CO2 for something useful, and get someone else to pay for it. Sounds like a win-win to me.

    • if it's the latter, and you're producing enough to actually power a carbon capture plant, then why would you burn fossil fuels at all?

      Simple answer: Direct capture can be done on demand with spare capacity. Powering your home cannot. You can decide when to turn off the DCC plant, yet you'll be hung drawn and quartered if you turn off the power to a few suburbs.

      Just because you haven't thought through all aspects of something doesn't make it a scam.

    • The amount of energy in compressed CO2 is still less than the hydrocarbons that were burned to make it.

      • CO2 is produced by exposing lye (sodium hydroxide) to air to form Na2CO3 (sodium carbonate). The Na2CO3 is then reacted with lime (CaO) to form CaCO3 (calcium carbonate) in an exothermic reaction that requires no energy.

        CaCO3 is far less soluble in water than Na2CO3, so it precipitates and can be dried and powdered.

        The next step is to heat the CaCO3 to about 950C to release the CO2 and convert the calcium back into lime. This is the major energy-consuming step but uses cheap heat rather than expensive ele

There may be other industries (such as trans-oceanic shipping) but I haven't looked into that to the same extent. Maybe cargo ships could be electric (or even wind assisted electric). Eventually, airlines may (probably will) be required to offset t

      There are certain applications where the energy density of fuels are critical. The mention of Airbus in the summary might have tipped you off. There's no possibility of building a battery powered airliner in the near future, and very little possibility of building one that doesn't run on carbon emitting fuel.

      Carbon sequestration is a decent way of allowing such applications to be carbon neutral, particularly if it uses excess energy provided by renewables at peak times.

      In this case, one company is emitting CO2, while another collects and sequesters CO2. They are even doing these two things in different locations. Amazing!

      As they have yet to actually do the CO2 collection and sequestration they are selling, it may turn out to be a scam... but the technology is real.

    • Gradually withdraw govt subsidies for fossil fuels & plastics & see how quickly the industry diversifies into renewable energy. They can afford to, it's just that nobody's given them a reason to yet.
    • The answer to your question is quite simple, specifically it is that not all power sources are born equal. There is quite good example in TFA summary itself, if ones is willing to think about it - airplanes cannot run on solar or wind power, DAC can. Effectively this moves carbon burden from airlines, that really have to rely on gasoline for its energy density and transportability, to DAC, that can take advantage of alternative energy sources to extract carbon.

        That is not a carbon neutral cycle. The only part that is carbon neutral is the release of the carbon sequestered by the tree during it's growth -and then it is still a question of timeframe: if it is released faster than it is sequestered you still have an increase in atmospheric carbon. All of the effort involved in harvesting, processing and transporting is additional carbon release.
