Mi bi l i l A tiMicrobiological ActionIt i iti l t l k t thIt is critical to look at the microporosity system, kerogen content and macerals for storage and/or generation sites for methane.Gas generation will come fromGas generation will come from contact of methane-producing bacteria with organic material. P d d ill tProduced gases will generate fractures in coal which will produce more surface area contact and more gas generation

F ibilit SFeasibility SummaryTests to-date have generated positive data using microbial processes to enhance methane release/generation in Bulli and Chinese coalsUp to 72% methane has been generated in serum bottle reactor headspaceUp to 6% hydrogen has been generated in serum bottle reactorUp to 6% hydrogen has been generated in serum bottle reactor headspaceBest methane generation is in H10 methanogenic mediaB t h d ti i i X70 h lith t hi diBest hydrogen generation is in X70 chemolithotrophic media and S10 halophilic mediaMethane production via release of chemically-bound methane from coal appears to account for about 50-60% of methane and other methane generation appears to account for about 40-50% of the methane in preliminary tests
