The U.S. Environmental Protection Agency has recognized
JHCGA’s leadership in promoting clean coal in China with a grant (cooperative
agreement XA-83396201) to identify and explore opportunities for recovery and
utilization of methane emissions from coal mines in China’s Shanxi province.
Shanxi province leads China in coal production with almost 650 million tons per
year and with coalmine methane (CMM) emissions of over 65 million tons of carbon
dioxide equivalent per year – roughly the entire amount of annual CMM emissions
in the U.S.
Methane is a combustible gas which must be extracted for safety reasons from
coal mines prior to and during mining operations. As an alternative to simply
releasing it into the atmosphere, where it has over 20 times the heat-trapping
capacity of carbon dioxide, it can be deployed as a clean-burning fuel source
equivalent in chemical composition and energy content to conventional natural
gas. The purpose of the JHCGA project is to help prepare the way for commercial
projects to develop such alternatives in Shanxi province.
The project extends over an 18-month period from November 2008 to May 2010. It
began with a meeting in the municipality of Jincheng which brought international
experts on CMM recovery and utilization together with key municipal government
officials and leaders of mining enterprises. Jincheng, a city of 2.2 million
population in southern Shanxi province, contains roughly ¼ the total coalmine
methane and coalbed methane resources of China at 6.8 trillion cubic meters.
Jincheng also leads China in rates of both extraction of methane (40-45%) and
utilization of extracted methane (55-60%). For example, the city is home to the
largest CMM-fired power plant in the world, a 120 MW facility built by
Caterpillar and financed largely by the Asian Development Bank.
The Jincheng meeting concluded with a declaration pledging the cooperation of
key signatories, including the Jincheng Municipal Government, the Shanxi Foreign
Affairs Office, GE/Energy (China), and JHCGA. The declaration embodies the twin
principles of energy conservation and emissions reductions – jie nang jian
pai -- and outlines key steps by which signatories propose to give concrete
meaning to these principles.
