Barriers and Opportunities for Reducing Methane Emissions from Coal Mines

Coal mining accounts for 8 percent of global methane emissions. While significant potential exists for abatement through degasification and ventilation air methane (VAM) oxidation, progress is hindered by policy, financial, and technological barriers. In China, legal frameworks and conflicting safety/emission standards create hurdles, while India lacks resource assessments. Russia faces issues with licensing and inefficient degasification systems. In the US, split-estate ownership on federal lands and a lack of federal mandates limit viability. The report suggests that while large-scale investment is available, a lack of small-scale funding for design and demonstration is a primary obstacle, proposing revolving funds and micro-loans as solutions.

• Coal mining is a significant contributor to global climate change, accounting for approximately 8 percent of total global methane emissions, which were estimated at 27.8 MMT CH4 in 2010.
• Underground coal mines are the primary source of CMM emissions. Methane can be reduced through pre-mining degasification, draining 'gob' from post-mining operations, and using new technologies to oxidize low-concentration ventilation air methane (VAM).
• In China, CMM abatement is hindered by a legal framework where the central government owns CMM rights and a Ministry of Environmental Protection standard that requires the use or flaring of gas with concentrations above 30 percent, which may conflict with safety principles by encouraging the dilution of gas toward the explosive range (5-15 percent).
• Russia's CMM recovery is limited by the fact that only 25 percent of active mines have degasification systems, and many existing systems were designed for safety rather than utilization, often producing gas with concentrations below the 25 percent regulatory minimum for use.
• In the United States, CMM project viability is impacted by the lack of federal legislation to limit greenhouse gas emissions and complex ownership issues on federal lands, where oil and gas estates are separate from coal estates.
• A critical financial barrier to CMM implementation is not a lack of large-scale investment, but a shortage of small-scale funding for project design and demonstration. The report proposes three funding vehicles: revolving funds for demonstration projects, micro-loans for entrepreneurial catalysts, and grants for feasibility studies that build in-country capacity.
