A US oil producer is teaming up with a company working to grab planet-warming carbon dioxide (CO2) straight from the air in a bid to extract more oil from the ground in a greener way, the companies said on Tuesday.
Occidental Petroleum is partnering with Canada-based Carbon Engineering to build a new multi-million-dollar direct air capture (DAC) plant in the Permian Basin, the largest US shale oil field, located in West Texas and south-eastern New Mexico.
The CO2 sucked from the air will be used to push out hard-to-reach oil from ageing fields, Steve Oldham, Carbon Engineering’s chief executive, said on the side-lines of theCO2NNECT 2019 meeting in Wyoming.
Oldham said the plan will mean as much CO2 will likely be captured as will be released in both the drilling of the oil and its subsequent use to heat homes or power vehicles.
It is possible the plant will do even better than breaking even and grab more CO2 than is produced, he said.
Construction is expected to begin in 2021 and take two years, Carbon Engineering said.
“It’s not so much that the fossil is the enemy here, it’s the carbon contained in it,” Oldham said.
“You can offset that the way we’re doing (it).”
Oldham said the plant would be 100 times larger than any other direct air capture plant in the world and will be powered by a mix of natural gas and renewable energy.
Carbon Engineering, which has been removing CO2 from the atmosphere since 2015 at a pilot plant, has been leading the market, alongside Swiss firm Clime works and US-based Global Thermostat.
The International Energy Agency says capturing carbon will be needed to limit a global rise in average temperatures to below 2 degrees Celsius (3.6F) above pre-industrial times by2060.
CO2 captured as part of the partnership would provide Occidental with “CO2 at a lower cost than our organic CO2 that we use today,” said Vicki Hollub, the company’s chief executive officer.
Occidental Petroleum is an investor in Carbon Engineering.
Kurt Waltzer, who is managing director of environmental advocacy group Clean Air Task Force, welcomed the announcement as one that “couldn’t happen too soon.”
But he warned that scaling the technology worldwide as climate change marches on would prove challenging.
“I like to step back a bit. The $25 trillion global energy infrastructure that we have to eliminate all the emissions from in 30 years, that’s unbelievably hard,” he said.
