World’s largest cow manure biogas project to begin production this year

Oilfield Technology,


Helping to alleviate China’s energy shortage, the new Liaoning Huishan Cow Farm is going into commercial production in September 2010. Once completed, it will become 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 gas engines. The energy generated will be sold to the state grid in China.

One of the features of the project is the utilisation 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 fertiliser, thus the surrounding land will become a base for organic agriculture.

When the new biogas power generation project is completed, it will be the world's largest cow manure project. It will not only serve China's national economic and environmental development goals, but it also is expected to reduce about 180,000 tonnes of CO2 emissions per year.

Biogas offers customers several advantages. It provides an alternative disposal of dung, liquid manure and bio-waste, while simultaneously harnessing them as an energy source, a substitute for conventional fuels. It also has the high potential for reduction in greenhouse gases and is highly efficient for combined onsite power and heat generation. In addition, the remaining substrate from the digester can be used as high-quality, agricultural fertiliser, characterised by neutralising the acid effect with a higher ph-value, keeping nutrients retained and nearly odourless.

“We are glad to be a part of the Huishan gas energy project as China and other countries in Asia seek to harness their own diverse renewable and alternative resources to create cleaner sources of energy,” said Prady Iyyanki, CEO, gas engines for GE Power & Water.
