Capture Carbon in Concrete Made With CO₂ (Javascript required):

On a vast grassy field in northern Wyoming, a coal-fired power plant will soon do more than generate electricity. The hulking facility will also create construction materials by supplying scientists with carbon dioxide from its exhaust stream.

A team from the University of California, Los Angeles, has developed a system that transforms "waste CO₂" into gray blocks of concrete. In March, the researchers will relocate to the Wyoming Integrated Test Center, part of the Dry Fork power plant near the town of Gillette. During a three-month demonstration, the UCLA team plans to siphon half a ton of CO₂ per day from the plant's flue gas andproduce 10 tons of concrete daily.

[...] Carbon Upcycling UCLA is one of 10 teams competing in the final round of the NRG COSIA Carbon XPrize. The global competition aims to develop breakthrough technologies for converting carbon emissions into valuable products.

[...] Cement, a key ingredient in concrete, has a particularly big footprint. It's made by heating limestone with other materials, and the resulting chemical reactions can produce significant CO₂ emissions. Scorching, energy-intensive kilns add even more. The world produces 4 billion tons of cement every year, and as a result, the industry generates about 8 percent of global CO₂ emissions, according to think tank Chatham House.
