Shanghai, February 23, 2012 — GE Jenbacher gas engines will power a Chinese landfill gas power generation project. The Laogang LFG project is owned by Laogang Renewable Energy Co., a joint venture formed by Veolia and Shanghai Environment Group.
China’s government plans to invest more than $412.8 million in the waste treatment industry including waste-to-energy initiatives by 2015.
Seven of GE‘s Jenbacher J420 gas engines, which will provide about 10 MW of electricity, will power the new Laogang LFG facility located in Shanghai. Each J420 engine combusts 2.7 million cubic meters of methane each year, providing an overall yearly reduction of greenhouse gas of around 18.9 million m³ for the seven gas engines. The Renewable Energy Co. will sell any excess electricity generated to the grid.
GE’s Jenbacher landfill gas engines use the gas — consisting of methane, carbon dioxide and nitrogen — created during the decomposition of organic substances in a landfill. Methane has a global warming factor 21 times greater than carbon dioxide, the most widely recognized greenhouse gas affecting climate change.
With a calorific value of about 5 kWh/Nm³, landfill gas constitutes a high-value fuel for gas engines that can be effectively used for energy generation. One of GE’s Jenbacher J420 gas engines running on landfill gas can generate 1.4 MW electricity while saving the emissions of more than 49,000 metric tons of CO2-equivalent per year through methane destruction and displaced grid electricity production; this is equivalent to the annual CO2 emissions of more than 9,500 passenger cars on U.S. roads.
The gas engines are scheduled to begin shipping in the second quarter of 2012 with commercial operation expected in December 2012.
