Fuel cell power plants can utilize landfill biogases to generate ultra-clean renewable energy

landfill-stock-photo_smThe decomposition refuse within landfills generates methane, a harmful greenhouse gas. Advanced aggregation systems that collect the gases emitted by landfills are a potential fuel source for our stationary fuel cell power plants.

Landfills may flare these biogases or let them escape into the atmosphere, but both of these disposal methods are harmful to the environment. Flaring wastes a potential fuel source and generates pollutants from the combustion process. Methane is approximately twenty times as damaging to the atmosphere as carbon dioxide (CO2), so allowing it to escape into the atmosphere is highly problematic.

Fuel flexible stationary Direct FuelCell® (DFC®) power plants utilizing renewable biogases produced in landfills can economically transform these waste disposal challenges into ultra-clean power and valuable revenue sources, efficiently and reliably.

Special Considerations

Generally, a biogas composition of at least 60-percent methane is needed for the economics of a fuel cell power plant to be attractive, although automated blending of the biogases with natural gas may be a desirable option if regulatory concerns are of paramount importance. The consistency and purity of the biogases may vary over time. FuelCell Energy has expertise with automatically blending biogas with natural gas as needed, ensuring a consistent and reliable supply of power.
