CarbonCure Technologies demonstrates CO2 capture and utilisation

CarbonCure Technologies claims that it has led a team of five companies to demonstrate the world's first integrated CO₂ capture and utilisation (CCU) from cement for concrete production.

CO₂ emissions from the Cementos Argos' Roberta cement plant near Calera, Alabama, were captured by Sustainable Energy Solutions’ (SES) cryogenic CO₂ capture technology, transported by Praxair, Inc and reused in Argos' Glenwood (Atlanta) concrete operations equipped with CarbonCure's CO₂ utilisation technology.

The concrete manufactured with the waste CO₂ from the Argos Roberta cement plant was then used in a local construction project in the greater Atlanta area.

The project was an extension of Team CarbonCure's participation in the US$20m NRG COSIA Carbon XPRIZE Challenge, which incentivises and accelerates the development of integrated CCU technologies and new markets that convert CO₂ emissions from coal and natural gas power generation into valuable products.

Other design partners and fellow members of CarbonCure's US$$20m NRG Carbon XPRIZE winning team included LS3P Architects, Uzun + Case Structural Engineering and Walter P Moore Structural Engineer.
