California gets 2.8 MW biogas fuel cell
Ontario, Canada-based Anergia Inc. recently brought a 2.8 MW biogas-powered fuel cell online at a California waste water treatment plant. The San Bernardino County, Calif., municipal waste district Inland Empire Utility Agency’s RP-1 Water Recycling Facility can treat up to 44 million gallons of wastewater per day. Anergia, which owns and operates the fuel cell, is selling the resulting power and heat to IEUA under a 20-year power purchase agreement. The electricity produced through the project will be enough to offset approximately 60 percent of the water treatment plant’s grid-derived power.
Danbury, Conn.-based FuelCell Energy Inc. supplied the technology for the project. The process requires only minimal cleaning of the biogas, including humidity and sulfur removal. The project at IEUA hosts FuelCell Energy’s largest size system, the DFC3000, which can also be deployed at hospitals, universities, large complexes and utility grid support applications.
