Carbon capture 'moonshot' moves closer, as billions of dollars pour in
As the world dices with the climate emergency, businesses and governments are starting to push funding towards technology that aims to trap planet-heating gases rather than let them saturate the atmosphere. Carbon capture is a controversial idea, attacked as a costly distraction from stopping emissions occurring in the first place. But last month, the International Energy Agency said it was an imperative part of the mix, warning that it would be “virtually impossible” for the world to hit climate targets without capturing and storing emissions generated from factories, power plants, transportation and other sources.
The transition to renewable energy, such as solar and wind, would not cut emissions in time, the IEA said. Producing cement, the key ingredient in concrete, creates so much CO2 that if the industry were a country only China and the US would emit more over the course of a year. CarbonCure works with nearly 300 concrete producers to inject captured CO2 into their product. The injected gas chemically transforms into limestone, reinforcing the concrete. Amazon will use the concrete in its buildings, including its vast new headquarters in Virginia....
