US: CarbonCure has demonstrated an integrated CO2 capture and utilisation (CCU) process from cement for concrete production in January 2018 at Cementos Argos’ Roberta plant in Calera, Alabama. The consortium - comprising Carbon Cure, Sustainable Energy Solutions (SES), Praxair, Cementos Argos and Kline Consulting - says it is the world’s first project to collect cement kiln CO2 for subsequent utilisation downstream in concrete production and construction.
CO2 emissions from the Roberta cement plant were captured by SES’ Cryogenic CO2 Capture technology, transported by Praxair and reused in Cementos Argos' Glenwood, Atlanta concrete operations equipped with CarbonCure's CO2 utilisation technology. The concrete manufactured with the waste CO2 from the Roberta cement plant was then used in a local construction project in the greater Atlanta area. Design partners and fellow members of CarbonCure’s Carbon XPRIZE team such as LS3P Architects, Uzun + Case Structural Engineering, and Walter P Moore Structural Engineers completed the end to end integrated solution by creating demand for CarbonCure concrete products in the marketplace. Kline Consulting oversaw the commissioning and reporting of the industrial demonstration.
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.
