Transcripción del abstract original del autor: Coal seams provide huge CO2 storages and promising sources of methane. Researches are devoted to a deeper understanding of CO2-coal interaction, to monitoring of CO2 behavior in coal seams, etc. Supercritical CO2-enhanced coal seam gas recovery (ECGR) and in situ fire-free microbial gasification of coal can produce sufficient amount of methane for the CO2 emission-free closed-circuit power plant and new type of coal mines without underground works. Sedimentary basins are suitable as CO2 storages and microbial CO2- CH4 converter to accommodate large volume of CO2 from burning of fossil fuels and refuse-derived fuels (RDF). Subsurface biogeochemical carbon recycling may realize greenhouse gas control with restoration of energy resources.
