New project aims to scale up rapid carbon-capture process

By Mary Page Bailey |

A new project is exploring a unique large-scale carbon-capture facility in the U.S. Technology developer Svante, Inc. (Burnaby, B.C., Canada; www svanteinc.com), is working with LafargeHolcim, Oxy Low Carbon Ventures, LLC and Total S.A., to evaluate the construction of a facility that will capture up to 725,000 metric tons per year of carbon dioxide from LafargeHolcim’s cement plant in Florence, Colorado. The facility would be the first large-scale commercial application of Svante’s carbon-capture process, which employs tailor-made nanomaterials instead of conventional liquid solvents. “We are using nanomaterials called solid sorbents with a very high storage capacity for CO2,” explains Claude Letourneau, president and CEO of Svante. The company engineered these materials to capture and release CO2 in less than one minute, whereas traditional technology may take hours. According to Letourneau, this faster turnover time means that a much smaller volume of sorbent material is required, resulting in a much more intensified process and lower capital costs relative to traditional processes, such as liquid-solvents. Svante has also developed a rotating device with laminated filter structures to capture and release the CO2 and regenerate…
