A Feasibility Assessment Unit (FAU), the first phase of an algae farm installation, is a mobile unit designed to evaluate a facility's site conditions for optimal deployment. Utilizing proprietary equipment and testing methods, experiments are conducted to select an algal species suited to the facility's local climate and gas composition. The unit has a small footprint and does not interrupt ongoing site operations.

GreenFuel recently completed feasibility studies at NRG's Big Cajun II, a 1,500-megawatt coal generating station, testing which algae grow with the plant's flue gases. “Coal is - and will remain - the premier domestic fuel source for power generation purposes in the United States for the foreseeable future,” said David Crane, CEO of NRG. “This means it is incumbent upon us...to find the best way to retrofit the country’s existing fleet of coal plants for post-combustion carbon capture.”

Other recently completed feasibility studies include the Sunflower Electric facility in western Kansas and the APS Four Corners facility.
