A beer-powered brewery

How Sierra Nevada does it:

FuelCell Energy has upgraded its 1 megawatt Direct Fuel Cell (DFC) power plant at Sierra Nevada Brewing Co. to use fuel created from a waste byproduct of the brewing process.

The brewery’s fuel cell power plant had been running on natural gas. Now, in an effort to increase efficiency and be more environmentally friendly, it runs on the brewery by-product methane.

Manufacturing.net reports that 20-40% reduction in fuel costs for the plant is possible by the 250 to 400 kilowatts of electricity that it can produce via biogas.
