A demonstration scale photobioreactor (PBR) is being operated and expanded at Duke Energy’s East Bend Station located in Union, KY. The PBR converts the CO2 in flue gas to algal biomass, via photosynthesis.

The biomass is then periodically harvested to supply feedstock for upgrading into value added products. The low energy harvesting system recycles water and unused nutrients. Partners include: KY Department of Energy Development and Independence; US-China Clean Energy Research Center-Advanced Coal Technology Consortia; ENN Group; and Pittsburgh State University.
