Exxon holds back on technology that could slow climate change

Exxon holds back on technology that could slow climate change

Exxon holds back on technology that could slow climate changeTechnicians examine the directair seize system on the Carbon Engineering Ltd. pilot facility in Squamish, British Columbia. Photographer: James MacDonald/BloombergElk and pronghorn antelope migrate every fall by southern Wyoming, the place the sparsely vegetated panorama slowly provides option to the foothills of the Rocky Mountains. Interrupting this serene vista is a dense internet of metal pipes, tanks, and pumps owned by Exxon Mobil Corp.

The industrial complicated supplies a clue about what lies beneath: an historical sea of coral and marine life, petrified by time and stress right into a thick layer of rock. Known because the Madison formation, this geologic construction is miles extensive and reaches greater than 10 Empire State Buildings under the bottom. It comprises pure fuel, helium, and carbon dioxide. Two of those gases are persistently useful to Exxon’s enterprise. The third shouldn’t be—and that’s an issue for everybody on the planet.

For three a long time, the American oil titan has been pumping up these gases, separating them, promoting some, and dumping the rest into the environment. Exxon produces extra CO2 than it may possibly promote or use, so the corporate lets loads float away—as a lot as 300,000 vehicles’ price of emissions a 12 months.

Exxon was set to embark on a undertaking to do the reverse: pump the undesirable fuel back down the place it got here from. The plan was technically and strategically simple. By capturing CO2, transporting it to an injection web site, and burying it, Exxon would have locked away sufficient of the planet-warming fuel to nearly remove the climate hurt attributable to the ability. The captured carbon could not have made a lot cash for Exxon on its personal, however a current change to the U.S. tax code would assist overcome that hurdle with profitable credit for secure storage. The firm put the full price of building at about $260 million, 1% of its capital budget for 2020.

LaBarge, because the fuel operation is understood, would have grow to be one of many world’s foremost examples of carbon seize and sequestration (CCS), a technology most climate-modeling consultants view as important to slowing down world warming and, ultimately, reversing it. The undertaking would additionally assist Exxon clear up its picture as one of many foremost company climate polluters.

Construction was set to start over the summer time. But in April, Exxon instructed Wyoming officers that the undertaking could be delayed indefinitely, due to fallout from Covid-19. The firm’s share value at one level throughout the pandemic dropped to an 18-year low, as oil costs cratered, throwing many plans throughout the business for this 12 months and past into turmoil.

Some conventional oil and fuel tasks are persevering with. In September, for instance, Exxon introduced plans to broaden crude operations off the coast of Guyana at a price of $9 billion—35 occasions the price of implementing CCS at LaBarge. Guyana is simply one of many progress tasks that would have fueled a pointy enhance within the firm’s carbon emissions, in accordance with inside projections from earlier than the pandemic reviewed by Bloomberg Green. If LaBarge had gone forward, on the opposite hand, it could have been one of many largest carbon-capture tasks operated solely by Exxon, making up nearly 20% of the corporate’s new emission-reduction efforts out to 2025, in accordance with the paperwork.

LaBarge “remains in our capital plans, and the permitting process and necessary design work continue,” says Exxon spokesman Casey Norton. Spending cuts “have impacted projects across all business lines.” Exxon has mentioned estimates within the planning paperwork are preliminary and don’t embrace extra measures to chop emissions.

The resolution to pause issues in Wyoming received’t cease growth of CCS, however it’ll slow down worldwide deployment. There at the moment are 26 large-scale carbon-capture tasks, in accordance with the Global CCS Institute. Exxon additionally has a stake in a big facility in Australia in addition to others in Qatar and the Netherlands, and Norton says the corporate has “expanded our interest in carbon capture significantly” over the previous two years.

Taken collectively, all of the world’s current seize amenities can zero out greater than 38 million metric tons of CO2 a 12 months. That quantity, about 0.1% of all world emissions, must rise 100-fold to 200-fold by 2050 to fulfill climate targets, in accordance with the International Energy Agency.

Most of those carbon-capture tasks are run by fossil gas corporations. Big Oil likes to rejoice the technology: By placing carbon back within the floor, the business can present customers with the advantages of fossil gas with out the complete climate influence.

“If you’re going to ask somebody to actually do carbon capture, oil companies have all the experience,” says David Use, a former Chevron Corp. engineer who bought a number of the gases from LaBarge to be used on the Rangely oil discipline, about 200 miles south, in Colorado. “They’ve got the pocketbooks and the credentials to do the big projects.”

And therein lies the paradox. As Exxon and its friends look right into a carbon-constrained future, CCS appears to supply a golden alternative. Oil corporations could develop a instrument thought-about essential by a minimum of the scientists with the United Nations-backed Intergovernmental Panel on Climate Change. But within the absence of robust authorities help or regulation, the oil business won’t have the need to speculate sufficient. Even if Exxon at some point completes its plans in Wyoming, the present delay reveals that pressing climate tasks can typically grow to be expendable in a crunch.

Carbon seize wasn’t created to sort out climate change. Oil and fuel deposits usually comprise giant quantities of carbon dioxide, which have to be separated out earlier than the gas might be offered. In its early days, that’s all of the technology was used for—catch and launch.

As a outcome, carbon seize didn’t comply with the standard clean-energy pathway. Many applied sciences transfer from laboratory to mass scale with assist from taxpayer cash. Research grants help the early phases, adopted by subsidies to encourage deployment. A rule of thumb holds that when a brand new technology doubles its presence within the wider market, the method turns into extra environment friendly and prices fall. Solar panels, wind generators, and lithium-ion batteries have all adopted this trajectory over the previous twenty years.

Carbon seize took a extra market-oriented route, although its earnings potential was at all times slight. The first actual business software, within the Thirties, got here in tools upkeep. Then the technology turned helpful in submarines, to gather the breath exhaled by crewmen and hold it from constructing as much as poisonous ranges.

By the Nineteen Seventies, petroleum geologists found out that injecting CO2 into oil reservoirs did one thing miraculous: produce extra oil. Compressed CO2 acts like cleaning soap, pulling crude from the tiny sedimentary pores of enormous underground reservoirs. The business calls the method enhanced oil restoration, or EOR. “Even today the overwhelming majority of capture and storage projects are associated with EOR,” says Julio Friedmann, senior analysis scholar at Columbia University’s Center on Global Energy Policy.

Fossil fuels had been first found within the LaBarge discipline in 1920, but it surely was solely within the Eighties that Exxon first started promoting gases from the positioning. Once separated from carbon dioxide, pure fuel is used for heating and cooking in properties and offered to energy crops to generate electrical energy. Helium is prized for analysis and medical functions, comparable to working MRI machines; it’s additionally helpful in producing fiber-optic cables and semiconductors.

But there was extra CO2 popping out of LaBarge than Exxon could promote. After oil costs plunged under $100 per barrel in 2014, enhanced oil restoration misplaced its attract. The shale increase additionally despatched costs for pure fuel into free fall. That left Exxon relying on helium, a comparatively uncommon commodity, to shore up earnings.

Meanwhile, the calls for on Exxon to cut back its emissions bought louder, and the corporate started to consider a long-term answer for its extra CO2. LaBarge additionally produced small quantities of poisonous hydrogen sulfide, which the corporate realized to bury back within the discipline together with some CO2. What about injecting all of it back into the Earth on a a lot bigger scale? The Madison formation is capped by a thick layer of impermeable rock, so the CO2 wouldn’t be capable to escape. The transfer could ship a public-relations increase. Most vital, LaBarge supplied an nearly painless option to decrease emissions with out hurting any moneymaking belongings.

The massive sticking level, in accordance with individuals accustomed to carbon seize at Exxon, is that the LaBarge growth must be worthwhile sufficient for the corporate to take it severely. A instrument that would profit the planet wanted to first present it could drive income for Exxon. Would capturing carbon be price it?

The prospect of constructing one of many world’s largest carbon-capture amenities generated pleasure inside Exxon.

LaBarge had the eye of senior administration, and there was even a proposal for Chief Executive Officer Darren Woods himself to disclose the undertaking to Wall Street by the tip of 2019, in accordance with individuals accustomed to Exxon’s carbon-capture tasks. But the large announcement by no means got here. During an investor presentation on March 5, Woods made solely a basic assertion. “ExxonMobil has cumulatively captured more carbon dioxide than any other company, accounting for more than 40% of all carbon dioxide captured in the world,” he mentioned. “We agree with independent experts. Carbon capture is absolutely necessary if society is going to achieve its aspiration of eliminating carbon dioxide emissions.”

He didn’t point out LaBarge. A couple of weeks later, confronted with world cutbacks as a result of pandemic, Exxon notified state regulators in Wyoming that the undertaking could be delayed indefinitely.

The resolution to place the undertaking on maintain got here as a blow to these inside the corporate who needed carbon seize to succeed. People accustomed to Exxon’s CCS tasks described it as a big setback, as a result of LaBarge was in a sophisticated state, used confirmed technology, and would have made cash. It gave these individuals the sense that carbon seize wasn’t a severe focus and that the technology’s climate potential had been handled like an undesirable addendum at a company devoted to grease and fuel.

Alex Doukas of the environmental group Oil Change International sees three motivations shaping the method fossil gas corporations take to carbon seize. First, they need to use CO2 to extend their total manufacturing. Second, they need to show they will produce “lower-carbon oil” and thus look extra accountable. Third, they need CCS tasks to assist justify ongoing operations and persuade regulators to not intervene. In the business that is known as the social license to function, and it’s one thing Exxon clearly considers.

The firm retains cautious inside accounts of its present and future emissions, together with what it phrases “self-help measures” to decrease the full, in accordance with planning paperwork reviewed by Bloomberg Green. Its self-help tasks, which embrace decreasing methane leaks and enhancing power effectivity, would have amounted to a discount of 11 million metric tons per 12 months—lower than 10% of Exxon’s present direct emissions. If the climate influence of shoppers burning Exxon’s fuels is taken into account, the corporate’s emissions-lowering measures seem far smaller.

“Exxon is employing a CCS strategy that is focused on using it as a public-relations tool and as a narrative tool to allow them to continue polluting,” Doukas says. Exxon says, on the contrary, that it takes carbon seize severely.

The firm spends giant sums of cash on all promoting—greater than $800 million from 2005 by 2015, in accordance with one estimate from Robert Brulle, a professor of surroundings and society at Brown University. One of Exxon’s more moderen Twitter adverts was a 36-second video discussing the potential use of gas cells in carbon seize. The clip ends by celebrating cooperation between an Italian researcher and Tim Barckholtz, a senior scientific adviser at Exxon.

It’s not the one advert to characteristic Barckholtz’s curiosity in gas cells—one other ran on Facebook as just lately as 2018. Exxon says a pilot undertaking is advancing, however large-scale use of the technology stays years away. Unlike the tried and examined strategies proposed at LaBarge.

The sluggish tempo of carbon seize’s growth is an indication that it’s not but a strategic match for the power business, particularly with oil and fuel costs at historic lows. “Most companies see CCS as a dead-weight economic cost,” says Columbia’s Friedmann. “Market adoption will require either large incentives or serious regulations limiting emissions.”

That’s what did the trick in Norway. Starting in 1991, the federal government adopted a steep carbon tax. The state-owned oil firm, now known as Equinor ASA, bore the brunt and located it cheaper to bury carbon dioxide than pay taxes on emissions. Norwegian CCS tasks constructed within the Nineties are persevering with to pump down, mitigating a number of the climate harm from the nation’s giant oil and fuel sector.

It could appear ironic that President Trump, well-known for reinforcing coal and doubting climate change, supported one thing comparable. A tax program meant to encourage carbon seize had been on the books since 2008, however the credit amounted to lower than a fifth of the standard price of the method. In 2017 a bipartisan group of lawmakers greater than doubled the worth of the tax credit score, referred to as 45Q, to as a lot as $50 per metric ton. Trump signed it into regulation.

That seemingly helped persuade Exxon to be extra formidable about LaBarge. The planning paperwork present that a primary section of the undertaking was estimated to seize one million metric tons of CO2 yearly; a second section would have doubled that. All that carbon could have been buried in trade for tax credit, guaranteeing income even when there have been no different patrons.

Use, the previous Chevron worker who purchased CO2 from LaBarge, blames the delay on an absence of want amongst business leaders to seize climate alternatives. “There are individuals that truly believe that we need to get on with carbon capture,” Use says of the oil sector. “There’s no leadership that seems to have really taken the baton.”

The pandemic has caught Exxon wrong-footed. The firm had begun a $210 billion plan to construct a brand new suite of oil, fuel, refining, and chemical operations by 2025. This try and improve its asset base and keep the dividend has largely been funded by new debt. Given that spending, Wall Street fell out of affection with its inventory, which was the most important single element of the S&P 500 as just lately as 2012. The carnage of Covid, which has wrecked demand for oil, noticed Exxon faraway from the Dow Jones Industrial Average.

Like many oil CEOs, Woods has been compelled to reverse course on his plans. He reduce Exxon’s capital price range by a 3rd, and spending will stay $10 billion a 12 months under prior forecasts by 2025. The strikes had been mandatory to avoid wasting the corporate’s fabled dividend, which stays the third-highest within the S&P 500 at a price of about $15 billion a 12 months.

Woods additionally shed workers. Exxon will lose 14,000 workers and contractors by 2022, becoming a member of Chevron and European friends Royal Dutch Shell Plc and BP Plc in enacting deep layoffs. Unlike Exxon and Chevron, which have mentioned they are going to stick with their oil and fuel experience, the European majors have used the present disaster to chop dividends and pivot towards renewables.

Whether or not oil corporations make investments sufficient in carbon seize, demand for the technology is ready to develop. The European Union, China, Japan, South Korea, and the U.Okay. are all among the many main economies that have set agency dates to succeed in net-zero emissions. By 2050, carbon-reduction tasks around the globe—together with nature-based options comparable to reforestation—could usher in as a lot as $1.4 trillion yearly, in accordance with Vivid Economics Ltd., a method consultancy. At that stage, the full income from sucking carbon out of the air would match these generated by the oil and fuel business right now.

Decisions comparable to Exxon’s have prompted carbon-capture advocates to focus on the cement and metal industries, which require immense quantities of power that up to now can’t be provided by low cost, clear alternate options. Some are focusing exterior the U.S. A Norwegian undertaking to seize carbon from a cement plant is backed by Equinor, Shell, and Total. British Prime Minister Boris Johnson introduced in November authorities help for CCS. Exxon and Shell are amongst corporations supporting the Netherlands’ Porthos undertaking to bury CO2 in empty fuel fields beneath the North Sea.

There’s additionally a crop of startups growing a brand new form of CCS technology: direct-air seize. Rather than gathering emissions from an influence plant or refinery’s chimney, these experimental machines would pull the fuel from the air. If direct-air-capture technology is run on renewable power, it’s able to delivering “negative emissions.”

Swiss firm Climeworks AG already has at the very least three pilot crops demonstrating that direct-air seize works. Carbon Engineering Ltd., based mostly in Canada, is working with Occidental Petroleum Corp. to construct its first large-scale plant. And Exxon is partnering in an effort to deploy direct-air seize with Global Thermostat LLC, a U.S. firm based by a former worker. Exxon says it’s expanded analysis within the discipline, however up to now the joint undertaking has generated promoting with out vital deployment.

No one expects carbon seize to brush the world in a single day, least of all Exxon’s CEO. Back in March, because the pandemic unfold, Woods warned buyers to be affected person. “Transitioning a large, complex, capital-intensive global system—that, by the way, plays an incredibly important role in people’s lives—is going to take time,” he mentioned.
