Oil company was storing a fraction of advertised amount of CO2 at offshore project, data shows.
This story is the tenth part of a DeSmog series on carbon capture and was developed with the support of Journalismfund Europe.
Equinor has retracted a claim that it stores about a million tonnes of carbon dioxide annually at its flagship carbon capture project after DeSmog obtained data showing the real figure was as little as a tenth of that amount.
The Norwegian oil company scrubbed the estimate from its website in November, when presented with official figures showing that it captured 106,000 tonnes of carbon dioxide (CO2) at its Sleipner carbon capture and storage (CCS) facility in 2023.
Equinor has not captured 1 million tonnes of CO2 per year at the site since 2001, according to the data, provided by the Norwegian Environment Agency.
The company put the reason for the discrepancy between the official figures and its public-facing claim to be capturing “about 1 million” tonnes of CO2 a year down to a failure to update a “static” webpage.
“We have now removed this error from our website and updated this section with the correct information,” Equinor spokesman Gisle Ledel Johannessen said via email.
Equinor has been capturing CO2 from a gas processing plant at the Sleipner gas field in the North Sea since 1996. The field has particularly high concentrations of CO2, which Equinor filters out during the gas purification process and then injects below the seabed.
The project has been cited by carbon capture advocates, and Equinor itself, as evidence that the technology is reliable enough to help meet global climate goals, despite its long history of cost-overruns and failed targets.
The claim has since been removed.
Expansion Plans
Equinor is positioning itself to play a key role in the European Union’s plans to massively increase carbon capture. The bloc has adopted an official target to deploy an annual 50 million tonnes of CO2 storage capacity by 2030 from roughly three million tonnes available across the continent today, though the pace of the existing roll-out is nowhere near on track to achieve that goal.
Norway, not an EU member, is home to almost all of Europe’s operational carbon capture capacity, which is comprised of Sleipner and a similar project also operated by Equinor at its Snøhvit gas field in the Barents Sea. The two sites stored a total of 763,000 tonnes of CO2 in 2023, according to the Norwegian Environment Agency figures, less than half of their combined capacity of 1.7 million tonnes of CO2.
Equinor’s statement that it was capturing “about 1 million tonnes of CO2 each year” at Sleipner alone appears to have first been published on the company’s “carbon capture and storage (CCS)” webpage in 2022, according to archived internet data. That year, the Sleipner field captured 260,000 tonnes of CO2, according to the Norwegian Environment Agency, which regulates the oil and gas industry.
DeSmog asked Equinor for its data on carbon capture at Sleipner in October. When the company declined to provide it, DeSmog obtained the figures from the Norwegian Environment Agency, which collates companies’ self-reported data.
Equinor spokesman Johannessen said that Sleipner had been capturing less CO2 in recent years because of declining gas production at the site.
Broken Equipment
Equinor had previously acknowledged that faulty monitoring equipment at Sleipner caused it to over-estimate the amount of CO2 it was capturing at the field for several years, as DeSmog reported in October. During a more than four-year period from January 2017 through March 2021, the company said that it had captured a cumulative total of about 2.7 million tonnes of CO2 at the site. Equinor later amended the figure to 2.1 million tonnes, about a 28-percent decrease.
The gulf between Equinor’s public claims and Sleipner’s actual performance underscores concerns among climate advocates that the oil industry is hyping the potential of carbon capture as a climate solution to deflect pressure to cut production of fossil fuels.
At least 480 carbon capture lobbyists attended the latest annual UN climate conference in Azerbaijan in November, according to the nonprofit Center for International Environmental Law. In October, DeSmog revealed that Equinor had been holding more meetings with ministers to lobby the UK government over CCS than any other company, part of its plans to play a leading role in the country’s carbon capture plans.
Equinor suggested that carbon capture could be the “best-kept secret” for climate action in a 2019 video, concluding that renewable energy sources such as wind and solar were “not enough.” In sponsored content currently viewable on the Financial Times website, Equinor says that CCS “has emerged as one of the key technologies in mitigating global warming” and addresses “misconceptions,” such as concerns over high costs and links to continued oil and gas production.
Ketan Joshi, an Oslo-based climate consultant, said that the way Equinor presents its CCS operations as a climate solution is “misleading” because its existing projects only capture a small proportion of emissions, while total fossil fuel emissions in Norway remain high.
“Equinor uses ‘ambitious’ CCS targets as a way of simulating action without actually performing it,” Joshi said. “They report the amount of CO2 they capture each year and it does not increase.”
CO2 Tax
The Sleipner CCS project was devised by Equinor (then Statoil) in the mid-1990s as a way to reduce its exposure to Norway’s newly implemented CO2 emissions tax. The company established its CCS project at Snøhvit in 2008 also to reduce its tax burden from CO2 released during gas processing.
“Sleipner and Snøhvit are CCS projects with high quality that rightly enjoy worldwide recognition from academia, industry, governmental bodies and science institutions as proven and safe CO2 storages over decades where Equinor and our partners so far have stored over 25 million tonnes of CO2 since 1996,” said Equinor spokesman Johannessen.
He added that over the past five years, the company has “injected 99.7 percent of the CO2 that has been captured on Sleipner into the ground.”
The amount of CO2 captured by Equinor’s two CCS projects is dwarfed by the emissions released by burning the oil and gas sold by the company. In 2023, Equinor recorded a total of 262 million tonnes of CO2 emissions — including the emissions produced by its operations, and the emissions from burning the oil and gas those operations extracted, according to company sustainability data.
In contrast, the company captured and stored a total of about 0.8 million tonnes of CO2 at Sleipner and Snøhvit, more than 300 times less than the amount emitted into the atmosphere by burning its products.
And even with a functioning carbon capture facility onsite, net CO2 emissions at Sleipner far exceeded the amount of the gas that was stored.
The Sleipner offshore platform provides power to several nearby gas fields by burning gas in turbines — a process that released 658,000 tonnes of CO2 into the atmosphere in 2023, according to the company’s sustainability reporting. That’s more than six times the 106,000 tonnes of CO2 that Equinor captured and stored from gas processing at Sleipner that year.
To reduce the offshore platform’s CO2 footprint, Equinor announced last April that it would introduce an electrification plan for Sleipner, rather than opting to expand CCS operations at the field. The company is also planning an electrification project to reduce emissions from the gas export facility at Snøhvit.
Government Subsidies
In September, Equinor and partners Shell and TotalEnergies inaugurated the Northern Lights CO2 transport and storage facility near the Norwegian port of Bergen, which the companies say will store 1.5 million tonnes of CO2 a year from industrial sources on the Norwegian mainland at full capacity when it starts operations.
The project is mostly financed by $1.2 billion in Norwegian government subsidies, with an additional $141 million pledged by the European Union.
By 2035, Equinor says it aims to store 30 to 50 million tonnes of CO2 a year from new projects announced in Norway, Denmark, the UK, and the United States — an exponential increase from its current capacity.
While Equinor has signalled that it will need substantial subsidies to go forward with its CCS plans, the company continues to direct most of its investments into extracting more fossil fuels. In August, chief executive Anders Opedal announced up to $6.7 billion a year to fund new Norwegian oil and gas drilling until 2035.
In contrast, Equinor said in November that it will cut its renewable energy division’s workforce by 20 percent — about 250 jobs — citing economic headwinds in the sector.
“At the most basic level, Equinor presents CCS in a similar way to many other major oil and gas companies: a ‘necessary’ part of the climate solutions mix,” said Joshi, the climate consultant. “This is presented alongside the company’s aggressive expansionist agenda: opening many new oil and gas fields.”
