Emerging cost competitiveness should enhance project economics
Potential global market for VAM oxidation and VAM-to-power applications is large
Field demonstrations are multiplying
Flow-reversal oxidation of VAM with power generation is a proven technology
Conclusions
---- Shorter payback time
---- Higher return on investment
Multiple vendors should lead to cost competition that will drive down project capital costs
---- Adds to energy security by beneficially using a currently wasted energy source
Capability to capture and beneficially use VAMs dilute energy content
Ability to mitigate the largest source of coal mine emissions worldwide
Technology Deployment Benefits
(e.g., electricity generation)
Oxidation with energy recovery
Oxidation only
Operational modes
Catalytic
Thermal
Shengdong Technology options
Ventilation air methane (VAM) is largest source of coal mine methane (CMM) emissions
---- Methane drainage can supplement ventilation
Mines employ large scale ventilation systems to vent methane to the atmosphere
---- Well below the lower explosive limit (5% in air)
Mine safety regulations require gassy underground coal mines to assure that methane concentrations in the mine workings are maintained at safe levels
---- More than 20 times as potent as CO2
Methane is a powerful greenhouse gas
