$2M Grant For Greener Concrete
The Department of Energy granted UCLA a $2-million grant to research and develop a process to convert CO2 emissions into a form of concrete. Traditional cement comprises over 8% of manmade CO2 emissions; this potential product could have a carbon footprint 50-70% lower than regular concrete. The process uses calcium hydroxide to absorb CO2 emissions, which results in the creation of a limestone material. That material is then mixed with other concrete-making elements (sand, stone, water, chemicals) to make CO2Concrete. Initial UCLA findings show that this concrete offers a greener alternative to traditional concrete at a similar price point and without compromising strength or performance.
The final round of competition was originally scheduled for February, but due to the pandemic it actually commenced in June of 2020. To demonstrate the system on an industrial scale, the UCLA team moved its operation to the Wyoming Integrated Test Center in Gillette, Wyoming (pictured above) just prior to the final round of competition. The test center is part of Dry Fork Station, a coal-based power plant.
A UCLA research team has received a two-year, $2 million grant from the U.S. Department of Energy to support development of a process that can convert carbon dioxide emissions into construction materials.
