Biogas produced by anaerobic digestion of organic material at wastewater-treatment plants is often disposed of by flashing and not reused as fuel. Solid oxide fuel cells can convert the chemical potential energy of biogas fuel, combined with an oxidant, into electrical energy without the need for combustion.
The goal of this project is to design a solid oxide fuel cell and gas turbine hybrid for a wastewater-treatment plant. Excess fuel and heat generated by the solid oxide fuel cell are recovered and fed to a micro gas turbine in a cogeneration system that increases the overall efficiency of the system.
Previously underused biogas is thus used as a biorenewable fuel source, producing electricity that can then be sold back to the electrical grid to reduce the overall utility costs of the wastewater-treatment plant.
