Using data from FAU deployments, Engineering Scale Units (ESUs) assess the potential of full-scale production at a customer site. In addition, an ESU produces biofuels and feed for characterization. During this phase, host facility operations are not disrupted.

GreenFuel's ESU at the 1,060-megawatt Arizona Public Service Redhawk facility marked the first time that smokestack gases were used to grow algal biomass for conversion into biofuels. Read more about this installation in the Performance Summary Report. The project won Energy Emissions Project of the Year at the 2006 Platts Global Energy Awards.
