The Olivera Egg Ranch has a lot of chicken poop to deal with and they use a lot of electricity. Could a biogas fuel cell kill two birds with one stone?
If you’re familiar with the term “Fuel Cell” you’ve probably only ever seen it preceded by the word “Hydrogen” and that’s a shame. One of the greatest advantages of fuel cells are their flexibility. Biogas, like that from poultry feces, is just fine for an electricity producing fuel cell. It’s a shame that the industry rarely promotes it.
Solving common agricultural waste issues while providing renewable power
The 1.4 megawatt fuel cell power plant to operate on site at the chicken ranch should alleviate three serious issues for the egg producing operation and the surrounding community.
Waste: Currently the chicken poop is collected in a solid lagoon and later transported away by truck. However, a little searching around turns up plenty of local residents claiming their sewage runs untreated through drainage ditches and eventually into the San Joaquin River. The biogas production process would consume much of that waste to produce the ranch’s electricity, which brings us to the egg farm’s second issue.
Electricity: The amount of chicken turds produced by the current amount of chickens on site should produce enough power to keep the ranch off the grid. That means no long distance transmission loss and no greenhouse gas emissions from distant power plants required for the farm.
Heat: The microorganisms that consume the chicken waste and produce methane gas (biogas) as a by product do their job much better when they’re nice and warm. The fuel cell is designed to transfer the heat it creates using methane to produce electricity to the anaerobic digester that houses the solid waste and microorganisms.
The system should be up and running by the middle of 2011. With a bit of success it could serve as a model of how a little innovation and investment can reduce pollution and fossil fuel usage while saving money. We’ll be keeping an eye on this project. If you know of others like it, please comment.
