Utilization of fuel cells to beneficially use coal mine methane. Final report
DOE has been given the responsibility to encourage industry to recover and use methane that is currently being released to the atmosphere. At this time the only method being employed at the Left Fork Mine to remove methane is the mine ventilation system. The methane content was measured at one one-hundredth of a percent. To prevent this methane from being vented to the atmosphere, degasification wells are proposed. To use the coal mine methane, it is proposed to use phosphoric-acid fuel cells to convert methane to electric power. These fuel cells contain (1) a steam reformer to convert the methane to hydrogen (and carbon dioxide), (2) the fuel cell stack, and (3) a power conditioner that provides 200 kW of 60 Hz alternating current output. The environmental impacts and benefits of using this technology ware summarized in the report. The study indicates the methane emission reduction that could be achieved on a national and Global level. The important point being that this technology is economically viable as is demonstrated in the report.
