GE Energy powering China plant
Posted: 30 October 2007
Four of GE Energy’s ecomagination certified Jenbacher coal mine methane gas engines are generating electricity at a power plant in Shentangzui, Shanxi Province in northern China as the country expands its installation of distributed power systems to address its pressing energy requirements.
The project ties in with the country’s national energy Clean Development Mechanism (CDM) based on certified emissions reduction (CER) credits trading.
The power generated by the Jenbacher units will be sold to the regional grid, able to serve the electricity requirements of about 97,000 Chinese homes in that region.
This new project is owned by Shanxi Yang Quan Coal Industry (Group) Co. Ltd.
Methane is extracted from an active coal mine and then delivered via pumps, storage tanks and pipelines over a distance of several kilometers to the company’s Shentangzui Power Plant in the prefecture-level city of Yang Quan, located 100 kilometers north of Taiyuan city, capital of Shanxi Province – one of the leading coal producing regions in China.
The new Shentangzui Power Plant features four of Jenbacher’s JGS 620 GS-S.L. engines, with an electrical output of 3.044 MW each and an electrical efficiency of 40.6 per cent.
Generator sets were manufactured at GE’s gas engine headquarters and manufacturing center in Jenbach, Austria.
GE also provided power plant auxiliary equipment to its local authorized distributor for Jenbacher gas engines, Jebsen & Co. Ltd.
The turn-key equipment supply contract for this power plant project – including the coal mine gas pre-treatment and master control system – was awarded to Jebsen & Co. Ltd in 2006.
Capturing and utilizing the coal mine methane gas – a potent greenhouse gas and available energy source in the mining industry – for power generation with Jenbacher gas engines, means less gas is vented into the atmosphere.
In contrast to the dominant method of local power production – coal fired plants – utilizing this “free” waste gas for power generation will contribute to the Chinese government’s sustainable development goals for the region – including improved energy security and a more circular economy, a model that effectively balances economic development with environmental and resources protection.
Installation of the Jenbacher engines in Yang Quan was completed at the site in May 2007, and start up and commissioning conducted by GE’s Jenbacher business in August 2007.
“Given China’s role as the world’s leading coal-producing country, we are pleased to cooperate with Shanxi Yang Quan Coal Industry Group on this milestone project between our companies as China continues its efforts on curtailing industrial emissions by increasing the utilization of alternative energy sources, including methane gas from active coal mines,” said Prady Iyyanki, CEO of GE Energy’s Jenbacher gas engines division.
GE’s Jenbacher coal mine methane gas engines are popular in coal-producing countries, including in China, Australia and throughout Europe.
GE’s durable, cost-effective technology generates power with existing mine gas and lowers industrial emissions levels thereby lowering operating costs.
Numerous GE Energy products, including GE’s coal mine gas and biogas engines, are certified under ecomagination, GE’s corporate-wide initiative to aggressively bring to market new technologies that will help customers meet pressing environmental challenges.
GE Energy’s Jenbacher gas engine business, based in Jenbach, Austria, is a leading manufacturer of gas-fueled reciprocating engines, packaged generator sets for power generation and cogeneration systems as well as gas engines for mechanical drive applications.
Jenbacher engines cover an output range of 0.25 to 3 MW, expanding up to 4 MW with its recently introduced world’s first 24-cylinder J624 GS engine, which is scheduled to go into serial production in 2009.
The entire Jenbacher product portfolio operates on natural gas or a variety of specialty fuels, including landfill and coal mine gas or alternative fuels like biogas, sewage gas and industrial waste gas.
