US/Canada: XPrize has named CarbonBuilt and CarbonCure Technologies as the winners of carbon capture and storage (CCS) design prizes worth US$20.0m. The competition ran at two power plants in Wyoming, US and Alberta, Canada. CarbonBuilt won the contest at the Wyoming plant with a concrete-curing based system. The concrete produced has a lower carbon footprint than conventionally produced concrete, according to XPrize. CarbonCure Technologies won the Alberta contest with a design based on carbonating the water used in washing cement trucks. This reportedly formed a concrete-strengthening slurry.

XPrize has partnered with Elon Musk and the Musk Foundation to launch a second round of CCS design prizes worth a total US$100m.

US: A research team at Washington State University has developed admixtures using chitin derived from seashells. The Moscow-Pullman Daily News has reported that the substance enhances concrete’s performance when substituted for some of the cement content. The lower clinker factor may also decrease net emissions. Work has shown that lower volumes of the supplementary material are required compared to existing admixtures.
