Cows can generate electricity

Modern methane power technology (Cow Power) is a solution that works well for dairy and livestock operations, international media report.

The process involves storing manure in a covered lagoon for approximately 20-80 days (depending on temperature), during which methane gas released in the natural decomposition process is trapped under the lagoon cover and piped to a gas scrubber where potentially harmful ingredients are removed. It is then fed into an electric power generator to produce electricity.

Benefits of methane power generation technology include: odor control, production of renewable electric power (5,000 cows can generate up to 500 kW), heating of water for dairy operational uses, reduction of methane emissions.

In addition, methane gas power generation technology provides opportunity to create valuable carbon credits as new sources of farm revenue.
