The Biofuels and Environmental Catalysis (BEC) research group’s microalgae-based CO2 capture project was recently selected by the U.S. Department of Energy (DOE) as one of only 16 projects to receive funding through NETL’s Carbon Capture Program which funds development and testing of transformational carbon dioxide (CO2) capture systems for new and existing coal-based power plants.  The BEC research group is located at the University of Kentucky’s Center for Applied Energy Research. 

Biological CO2 Use/Conversion

A Microalgae–Based Platform for the Beneficial Reuse of CO2 Emissions from Power Plants

The research team at University of Kentucky Research Foundation (Lexington, KY) – with University of Delaware College of Earth, Ocean, and Environment (Newark, DE) and ALGIX, LLC (Meridian, MS) – will study microalgae-based CO2 capture with conversion of the resulting algal biomass to fuels and bioplastics. Scenedesmus acutus algae will be cultured in an innovative cyclic-flow photobioreactor; the algae will be harvested and dewatered using a University of Kentucky technology based on flocculation (a process where fine particles clump together)/sedimentation/filtration. The project will yield a conceptual design for an algae-based CO2 capture system suitable for integration with a coal-fired power plant. The project will last 24 months.  

Cost: DOE: $990,480; Non DOE: $266,935; Total Funding: $1,257,415
