Scientists at the Canadian Carbon Engineering have said they are to making carbon capture work. Carbon capture is the of capturing waste carbon dioxide (CO2) from places like power plants and then it so it does not harm the . Carbon Engineering say its scientists are close to capturing CO2 from the atmosphere and turning it into carbon-neutral . This could be a big step forward in the fight against warming. The scientists said they have greatly reduced the of carbon capture, to as low as $94 per ton of CO2 captured. Many scientists believed carbon capture would cost about $1,000 per captured.
The technology works by sucking into special industrial towers. The CO2 is mixed with an alkaline and frozen. It is then heated and combined with hydrogen. This produces liquid like gasoline and jet fuel. The of Carbon Engineering, Professor David Keith, was about the future of this process. He believes his company could help to combat climate change. He said: "After 100 of practical engineering and cost analysis, we can confidently say that while air capture is not some cheap solution, it is a viable and buildable for producing carbon-neutral fuels in the future, and for removing carbon in the long ."
