Abstract

Coal mines are the second largest contributor of anthropogenic methane (CH4) emissions with an estimated emission of around 5-30 Tg CH4 year-1. Considering the global warming potential of CH4 (~ 25 times that of CO2 over a 100 year period), developing a unique technology to mitigate the low levels of CH4 (0.2-5 %) emissions especially coming from coal mine ventilation air is highly important for countries with considerable coal reserves like Australia. A research project "Bioremediation of methane from mine ventilation air" jointly funded by the Advanced Manufacturing Cooperative Research Centres (AMCRC) and MBD Energy Ltd., Australia, aims to develop a dual culture system to convert CH4 into green fuels using indigenous bacteria and cyanobacteria in novel bioreactors. Methanotrophic bacteria are capable of metabolizing CH4 into CO2 under optimized bioreactor conditions. Subsequently, the CO2 can be converted into oxygen (O2) by cyanobacteria resulting in biomass generation for biofuel production. This study is the first of its kind in developing such novel bioreactors to implement at commercial sites after vigorous laboratory testings/optimization to mitigate both CH4 and CO2. Further, this technology is readily transferable to other CH4 generating industries like landfills, anaerobic composting systems and dairy farms. In addition, successful implementation allows claiming of Clean Development Mechanism (CDM) benefits for carbon capturing in Australia and other parts of the world.
