GE engines to power China's largest landfill gas-to-energy plant

By Anna Austin | February 23, 2012

A landfill gas-to energy project under development in Shanghai, China, is poised to be the largest of its kind in the country, and GE Energy has announced it will provide to the endeavor seven of its GE Jenbacher gas engines to produce about 8 MW of electricity.

Laogang Renewable Energy Co., a joint venture between Veolia and Shanghai Environment Group will own the facility and the electricity generated will be used on site, with excess sold to the grid.

Prior to the project, the landfill’s methane was released directly into the air. General manager of Laogang Renewable Energy Co. Chen Hongzhang said by using GE’s gas engines fueled by landfill gas, it will reduce emissions by more than 340,000 tons of carbon dioxide equivalent per year. Each J420 engine combusts 2.7 million cubic meters of methane annually.

The engines are designed to generate almost 80,000 megawatt hours of electricity per year, which could power more than 46,000 Chinese households, according to Rafael Santana, president and CEO of Gas Engines for GE Energy.

The engines are scheduled to begin shipping in the second quarter of 2012 with commercial operation expected in December.
