"Norwegian oil and gas company Equinor has admitted over-reporting the
performance of a flagship carbon capture and storage project by about 30
percent due to defective monitoring equipment, underscoring risks associated
with plans to scale the technology as a climate solution, DeSmog can reveal.
In a footnote in its latest sustainability data, Equinor said a malfunction in
equipment used to measure the amount of gas flowing through a pipeline at its
Sleipner gas field in the North Sea had caused it to over-report the amount of
carbon dioxide (CO₂) stored from 2017 to 2021.
“Due to a flawed flow transmitter at Equinor’s CO₂ injection facilities at
Sleipner, the figures for CO₂ injected were over-reported in the period
2017-2021,” the footnote said. “The transmitter was replaced in March 2021, and
the figures have been updated accordingly.”
Equinor did not quantify the extent of the over-estimates in the footnote on
Sleipner. The 28-year-old project is often cited by carbon capture advocates as
proof that it’s technically feasible to trap and store large quantities of CO₂
underground.
A DeSmog review of publicly available company data suggests that Equinor
captured and stored a cumulative total of 1.6 million tonnes of CO₂ at Sleipner
from 2017-2019, compared to its initial estimate of 2.1 million tonnes —
implying that it had previously over-reported the amount of gas stored during
that three-year period by about 30 percent. [See note on methodology at the end
of this story].
A lack of comparable data made it harder to estimate how much the company may
have over-estimated CO₂ capture at Sleipner in 2020 and early 2021, although
partial numbers suggested that the figure was also about 30 percent."
