Coal Bed Methane • Natural gas found in most coal deposits • Similar to natural gas • Created from buried plant material which was converted to coal by the pressure of being underground • When the coal seam is drilled and the water is pumped out, the gas begins to flow • Usually pure or ‘sweet’ gas and requires little processing
Problems • Adds Carbon Dioxide to the atmosphere • Contaminates drinking water supplies such as aquifers • the industry’s biggest problem is managing the volume of water, often with a high sodium content, that must be extracted before coal-bed gas begins to flow • Can remove water by truck and re-inject into spent gas wells but must be kept isolated from potential ground water zones
