Biogas production from cow manure is certainly nothing new in the field of renewable energy. Never before though, apparently, has a project unfolding in China been undertaken on such a large scale: 250,000 cows (!) producing enough cow poo to generate 38,000 MWh a year of converted biogas. At the heart of the new Liaoning Huishan Cow Farm will be four biogas engines from GE.
GE said its four GE JMS420 Jenbacher gas engines will generate renewable biogas energy which will be sold to the state grid in China. It is said that, besides producing biogas for power generation, one of the features of this project will be that 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
