Scientists are close to making carbon capture work. Carbon capture is capturing carbon dioxide (CO2) and storing it somewhere safe. A company called Carbon Engineering says it is close to capturing CO2 from the air and turning it into carbon-neutral fuel. This is a big step forward in fighting global warming. Scientists also said they have cut the cost of carbon capture from $1,000 per ton of captured CO2 to as low as $94 per ton.

The technology works by sucking air into special towers. CO2 is mixed with a liquid and frozen. This is then heated and mixed with hydrogen to make fuels like gasoline. A Carbon Engineering professor is hopeful about the future and the fight against climate change. He said: "We can confidently say that…air capture…is a [realistic] and buildable technology for producing carbon-neutral fuels in the…future, and for removing carbon in the long run."
