Trigeneration Project Using Landfill Gas Powered Fuel Cells

[font size=4]With the promise of ultra-low emission power generation, fuel cells have long been the holy grail of the power industry. But the hydrogen requirements of traditional low temperature units have been something of a stumbling block. That's a problem one U.S. based company has solved with its high temperature carbonate fuel cell.[/font]

"We send methane into our fuel cell stack and there's a reaction that occurs in the stack. The methane reacts with water. All the hydrogen in the water and the methane separate out and become pure hydrogen, and the oxygen in the water reacts with the carbon in the methane to become carbon dioxide," he explains.

"Our systems are designed to do that from almost any methane fuel. We can use natural gas, which is almost all methane or we can use biogas from anaerobic digestion, and that's maybe 60% methane or we can use landfill gas, which can be anywhere from 45% to 50% methane," adds Leo.



To that end, back in February this year the company signed a contract to demonstrate a 300 kW tri-generation stationary fuel cell plant at a landfill near Vancouver, Canada. The project will utilise landfill gas as the fuel source and generate electricity for export to the grid, heat for use by Village Farms' nearby hydroponic greenhouse facility and hydrogen for vehicle fuelling or industrial applications.



"This landfill project is interesting because in some respects it's a quadgeneration project. We're making electricity, heat and hydrogen, but also Village Farms are going to use the CO[font size="1"]2[/font] from our exhaust in their greenhouse. It's going to be blended with air and sent into the greenhouse to promote more rapid growth of the plants," says Leo.
