Who We Are
CO2Concrete is advancing a carbon use technology that originated in the Laboratory for the Chemistry of Construction Materials (LC2) at University of California, Los Angeles (UCLA). The team includes experts in energy, construction, and sustainable technologies, with emphasis in developing carbon-to-value (CTV) pathways. We are translating the core technology to the commercial scale to create u+nprecedented opportunity to reduce and monetize carbon across emissions-intensive industrial sectors. CO2Concrete is also a Finalist in the NRG COSIA Carbon XPRIZE competition.
What We Do
CO2Concrete is turning carbon dioxide (CO2) emissions into construction materials and products without a need for carbon capture. Our patent-pending technology upcycles CO2 with unparalleled efficiency, cost-effectiveness, and throughput into precast CO2Concrete™ products. This breakthrough technology replaces the more than century-old paradigm of energy-intensive and CO2-intensive manufacturing of ordinary portland cement (OPC)-based concrete, and concrete products. By converting CO2 emissions from power plants, cement plants, or petrochemical production into CO2Concrete™, we will enable base industries to transform and achieve their carbon emission reduction goals.
Carbon Capture Process
The CO2Concrete technology turns carbon dioxide emissions into CO2Concrete™ products that can replace traditional concrete, with a much lower CO2 footprint. The technology is based on the concept of “CO2 mineralization” – the conversion of gaseous CO2 into solid mineral carbonates (e.g., CaCO3) within the CO2Concrete™ products.
This chemical reaction is robust, and strengthens the fresh CO2Concrete™ products into components exceeding industry standard performance metrics. Key advantages of the technology include the following:
- Direct utilization of CO2 from flue gases without a need for carbon capture systems (e.g., amine strippers)
- Process flexibility to accommodate flue gas streams with widely varying CO2 concentrations, and presence of acid gases
- Process operates at ambient pressure and temperature, minimizing extrinsic energy requirements
- Material formulation requires no ordinary portland cement (OPC) to exceed industry standards for component performance
Applicable Industries
The CO2Concrete process can serve as the cornerstone of a CO2emissions reduction program for electrical power producers with coal- and gas-fired units, cement and pre-cast concrete companies, and petrochemical companies. This is possible because of the unprecedented flexibility of CO2Concrete process which utilizes dilute CO2 streams, thereby avoiding the need and enormous expense for CO2capture. Also, contributing to the flexibility of the process is its ability to tolerate common flue gas contaminants including acid gases, and particulate matter. This highly effective and efficient process can reduce CO2 emissions at levels which can meet or exceed the CO2 reduction targets for most, if not all, companies.
