China cow manure project to produce energy with biogas technology

August 25, 2010

Helping to alleviate China’s energy shortage, GE’s Jenbacher biogas engines will power the new Liaoning Huishan Cow Farm, which, once completed, will become the world’s largest biogas project based on cow manure.

The manure from the 250,000 cows at the Huishan farm, located in Shenyang, China, will be converted into biogas and is expected to produce 38,000 MWh a year through four GE JMS420 Jenbacher gas engines. The energy generated will be sold to the state grid in China.

One of the features of the project is the use of fuel circulation. In addition to the use of biogas for power generation, the liquid (residual from biogas production) will be used to nourish the grass in the pasture, and the solid waste can be sold as organic fertilizer, thus the surrounding land will become a base for organic agriculture.

The project will not only serve China’s national economic and environmental development goals, but it also is expected to reduce about 180,000 tons of CO2 emissions per year.

Commercial operation is scheduled to begin in September 2010.
