What find when a Chinese dairy farm farm takes the excrement from 60,000 of its 250,000 cows andconverts it into electrical energy ? They generate 5.66 megawatts of power , which is rough enough to power 3500 American homes .
harmonise to Technology Review , Huishan Dairy has make a methane convertor that is over 10 times the sizing of like such devices . Powered by four of the GE engines render above , the convertor captures methane from fermenting moo-cow poop and turn it into baron . Pop Scidoes a good job of summarizing the science behind the converter , which postulate processes like hydrodesulfurization and anaerobic digestion , so on and so forth .
But what ’s really interesting here is that the scale leaf of this convertor might be more economically appealing to dairy farm in the US . Currently , methane convertor in the US only generates 2 megawatts of power , and are only used by 1 % of farms . And considering the plant in China could trim back carbon emssions by over 180,000 tons , I ’m sure such a convertor would have the full support of green freaks stateside .
