Fuel cell company FuelCell Energy Inc is to supply fuel cell-based power plants to four locations in California, US.
First, a total of 4.5 MW of CHP plants will be supplied to BioFuels Fuel Cells, a California renewable energy company owned by New Energy Capital and BioFuels Energy.
Three fuel cell power plants, including a 2.8 MW DFC3000, a 1.4 MW DFC1500 and a 300 kW DFC300, will be installed at three different locations in the San Diego area and will utilize purified biogas from the Point Loma wastewater treatment plant as the primary fuel source for the generation of ultra-clean electricity.
The biogas generated at the Point Loma wastewater treatment plant represents a revenue source for the City of San Diego.
The project incorporates a unique solution that purifies the biogas on-site, and then injects the biogas into an existing gas pipeline to supply fuel cells at two different locations in the San Diego area.
Termed ‘directed biogas’, this project will show for the first time a FuelCell Energy power plant fuelled by renewable biogas generated at a distant location.
The 2.8 MW DFC3000 will be installed at the University of California, San Diego to supply power to the campus electrical grid, with by-product heat used as a power source for 320 tonnes of chilling capacity to cool campus buildings.
The 1.4 MW DFC1500 will be installed at the South Bay water reclamation plant in San Diego.
The power plant will provide baseload power around-the-clock, replacing power purchased from the electricity grid, with by-product heat used for heating needs at the pump station.
The 300 kW DFC300 fuel cell will be located at the Point Loma wastewater treatment plant and will generate the power required for the biogas purification process.
Separately, a 2.8 MW DFC3000 power plant is to be installed at a wastewater treatment plant operated by Inland Empire Utilities Agency (IEUA), a municipal water district based in Chino, California.
Renewable biogas created by the wastewater treatment process will be the primary fuel source for the generation of ultra-clean electricity.
UTS Bioenergy LLC will purchase the DFC3000 and sell the power generated to IEUA under a 20-year power purchase agreement.
FuelCell Energy will service the power plant under a long term service agreement and the unit is expected to be operational in early 2012.
