Wastewater treatment plants represent a unique opportunity for fuel cell power plants primarily due to their fuel flexibility and Combined Heat and Power (CHP) capabilities. The methane produced from the anaerobic digester process is used as the fuel to generate electricity that powers the wastewater treatment plant while waste heat from the fuel cell can be used to heat the sludge to facilitate the anaerobic digestion. Moreover, wastewater treatment gas is a renewable fuel eligible for incentive funding for projects in 22 states, Washington D.C., and many countries throughout the world.
FuelCell Energy has fielded thirteen Direct FuelCell® (DFC®) units to operate on biogas of which 70% are wastewater treatment applications. In many applications digestor gas production volume is variable. In such applications, the plant could be designed to operate with automatic blending with natural gas.
