Hebi Coal Mine Methane Power Generation Project Hebi Coal Industry Company Hebi Coal Mining Area, Henan, China OVERVIEW OF PROJECT OPPORTUNITY: Located in Hebi Coal Mining Area, in China’s central Henan Province, the project will reduce emissions by using gas, originally vented to the atmosphere, to generate electricity. The project is expected to reduce emissions by up to 300,000 tonnes CO2e each year. This project offers an excellent opportunity for investors. Hebi Coal Mining Area’s seams have a high gas content. The absolute gas emissions are 310.36 m3/minute and the relative gas emissions average 26.51 m3/tonne. The gas content of the coal averages 15.2 m3/t and the coefficient of permeability in seams is 1.2–1.8 m2/Mpa2·d. Gas is extracted from the coal seams that are mined in Hebi with difficulty. Currently, Hebi Coal Mining Area has installed underground and surface gas extraction stations in eight pairs of high- gas mines; the volume of gas extracted was 47.657 Mm3 in 2006. Some of the extracted gas has been used as fuel for power generation and residential consumption; however, gas emitted during mining operations is vented directly from the mine shaft to the atmosphere. The production capacity of Hebi Coal Mining Area will expand in the future. Hebi will make further efforts to extract gas, increasing the efficiency and capacity of the available extraction systems. These actions will improve worker safety and reduce greenhouse gas emissions. To fully utilize the gas extracted and achieve energy conservation and emission reduction, Hebi Coal Mining Area is planning to establish more gas power generation projects. It is planned that 22 gensets of 500 kW will be installed in Hebi Coal Mining Area in the next two years, with total installed capacity reaching 11 MW through an anticipated investment of $7,330,000 USD.

The project will not lead to the consumption of significant natural resources or to any increase in energy consumption because the pumping station has already been installed and drainage activities are part of the baseline.
