NRG Energy Inc., a wholesale power generation company, recently announced that it will team with GreenFuel Technologies Corporation (GreenFuel) and the New York State Energy Research and Development Authority (NYSERDA) to study carbon dioxide (CO2) recycling. The NYSERDA-funded study will assess the technical and economic feasibility of GreenFuel’s Emissions-to-Biofuel process, which harnesses the photosynthetic processes of algae to consume waste gases and heat from a power plant’s air emissions stream. This can then produce a high-energy biomass that could be used as biofuel.

The project will take place at NRG Energy’s Dunkirk power plant in western New York, where GreenFuel’s algae-based bioreactor will be placed in the power plant’s smokestack. According to the company, the bioreactor is easy to install and will cause only minimal impact on the plant’s electricity production. GreenFuel claims that for every two tons of algae, one ton of CO2 is removed from the air.

An algae-based bioreactor will be placed in the smokestack of a coal-fueled power plant, such as this one, in New York.

“Our key goals are, and have always been, to provide affordable, reliable, and environmentally responsible energy,” said NRG President and CEO David Crane. “In that regard, doing our part to advance technological initiatives that may reduce CO2 emissions from our plants is a moral imperative.”
