Tieling Coal Mine Methane Capture
Located across six coal mines in the Northeastern province of Liaoning in China, this project prevents the potent greenhouse gas, methane, from being released into the atmosphere. Methane is a by-product of coal formation which is released during mining. At each of the project sites, technology has been installed to capture the CMM and blend it to a concentration suitable for use as a fuel source. This innovative initiative was the first project in China to use CMM as fuel for gas supply.
Over half of China’s energy is derived from coal, making it the world’s largest global consumer of this fossil fuel. As a result, approximately 10.6 billion metres3 of CMM is released annually and less than 10% of this is currently piped as gas or used to generate electricity.
The Tieling project improves on earlier technology which was funded by the United Nations Development Programme along with the Japanese and Chinese governments to demonstrate methane extraction in China. These improvements have enabled the extracted CMM to be blended to a concentration high enough to supply two gas distribution companies.
Alongside the environmental benefits, the project enhances the local economy with the creation of 260 permanent engineering, construction and maintenance jobs and 291 temporary positions. The availability of gas for both industrial and domestic use displaces conventional fuel sources and increases energy sustainability in the local area.
