The first commercial collaboration between PHG Energy (PHGE) of Nashville and GE Power & Water business of General Electric is officially online and creating electricity from waste materials at a new Covington, Tenn., facility. GE’s Clean Cycle generator, based on the organic rankine cycle (ORC) technology, produces power by utilizing heat delivered through PHGE’s downdraft gasification system and waste-mixing process. The two companies successfully proved the coupling of the technologies in an extensive research and development project that resulted in the first collaboration. Now the system is deployed and functions using the city’s wood waste and sewer sludge.
