Scientists at Canadian company Carbon Engineering have said they are close to making carbon capture work. Carbon capture is process of capturing waste carbon dioxide (CO2) from places like power plants and then storing it so it does not harm environment. Carbon Engineering say its scientists are close to capturing CO2 from atmosphere and turning it into carbon-neutral fuel. This could be big step forward in fight against global warming. scientists also said they have greatly reduced cost of carbon capture, to as low as $94 per ton of CO2 captured. Many scientists believed carbon capture would cost about $1,000 per ton captured.

technology works by sucking air into special industrial towers. CO2 is mixed with alkaline liquid and frozen. It is then heated and combined with hydrogen. This produces liquid fuels like gasoline and jet fuel. founder of Carbon Engineering, Professor David Keith, was optimistic about future of this process. He believes his company could help to combat climate change. He said: "After 100 years of practical engineering and cost analysis, we can confidently say that while air capture is not some magical cheap solution, it is viable and buildable technology for producing carbon-neutral fuels in immediate future, and for removing carbon in long run."
