Gas from cow manure produces biomass, or "cow power" electricity by utilizing a biomass digester which creates methane gas to run an internal combustion engine. The engine turns a generator which makes electricity.
How does it work?
A manure digester collects and breaks down manure and to capture the resulting gas. Bacteria in the digester decomposes the manure to release biogas, which is 55-70 percent methane. The biogas is then piped to an engine which burns the gas and turns a generator to produce electricity.
The electricity is sold to ECE and we distribute it to ECE members.
