Somewhere in west Texas, amid one of the most productive oilfields in the continent, a Canadian company is building a plant that it hopes will eventually suck from the air a million tonnes of carbon being pumped out of the ground all around it.
Carbon Engineering91裸聊视频檚 groundbreaking plant is one of many projects hoping to help in the fight against climate change by turning its main driver 91裸聊视频� carbon dioxide 91裸聊视频� into a useful product that can be profitably removed from the atmosphere.
91裸聊视频淲e91裸聊视频檙e pulling the CO2 back down,91裸聊视频� CEO Steve Oldham said in a recent interview.
People in labs and boardrooms around the world are beginning to confront the realization that more needs to be done than cut emissions if the world is to remain livable. Vast amounts of carbon already in the atmosphere will have to be removed.
A 2017 paper in the scientific journal Nature Climate Change calculated that to stabilize climate change at two degrees Celsius, between 120 billion and 160 billion tonnes of CO2 will have to be sucked from the air and stored underground. That91裸聊视频檚 in addition to Paris agreement emissions cuts.
That would cost big bucks. And that, says energy economist Mark Jaccard, is why companies such as Carbon Engineering are so important. Using CO2 to make marketable products will help pay for the massive scale-up of technology to remove CO2 and inject it permanently underground.
91裸聊视频淵ou91裸聊视频檙e going to have to figure out some product you can make until humanity91裸聊视频檚 ready to use this for the real reason, which is to capture and bury carbon,91裸聊视频� said Jaccard of the University of British Columbia.
Carbon Engineering is already pulling CO2 from the air and turning it into fuel at its pilot plant in Squamish, B.C. In Halifax, CarbonCure Technologies is injecting CO2 into concrete.
Many companies already inject CO2 underground to force more oil to the surface 91裸聊视频� which, if done right, can result in carbon-negative oil. Other companies are using the gas to create useful chemicals, carbon nanotubes or plastics.
91裸聊视频淭here91裸聊视频檚 a number of technologies we91裸聊视频檙e trying to advance,91裸聊视频� said Wes Jickling of the Canadian Oilsands Innovation Alliance. The group is helping run the Carbon XPrize, a $20-million award for the best conversion of CO2 into a saleable product.
The market for such products has been estimated at $1 trillion a year.
The question is whether that91裸聊视频檚 a prize adequate to drive innovation and construction fast enough to start reducing atmospheric CO2 before global temperatures rise past 1.5 degrees. That91裸聊视频檚 little more than a decade, according to the United Nation91裸聊视频檚 Intergovernmental Panel on Climate Change.
The technology for burying carbon underground, known as sequestration, is well understood and is being used at full-scale sites in Alberta and Saskatchewan. But in 2018, the British Royal Society found that the pace of building such facilities needs to speed up by at least 100 times to meet the UN91裸聊视频檚 climate target.
Making products from CO2 also creates what91裸聊视频檚 known in climate circles as the moral hazard. If we can suck the gas out of the air, why bother emitting less of it?
We can91裸聊视频檛 count on a magic bullet to save us, said Jason Switzer, director of the Alberta Clean Technology Industry Alliance.
91裸聊视频淭here91裸聊视频檚 no question that we can91裸聊视频檛 keep deferring hard choices,91裸聊视频� he said. 91裸聊视频淲e do have to make difficult choices.91裸聊视频�
The world needs to emit far less carbon and take out much of what91裸聊视频檚 already there, Jaccard said. Building an industry based on removing it from the air is the best way to develop cheap and efficient ways of doing that.
91裸聊视频淧eople have to figure how to get enough support for these technologies they know we91裸聊视频檙e going to need.91裸聊视频�
