Amongst the cheapest and safest options for clean energy are to use natural gas from coal seams for electricity and fuel production and then permanently store carbon dioxide within the depleted seams. This requires information about the underground behaviour of coal at a level of detail which is not available. In particular, the directional and dynamic response of coal to changes in pressure, stress and gas interactions is required, which is the subject of this project. Coal bed methane is rapidly growing into a multi-billion dollar industry for Australia. The geosequestration of carbon dioxide in deep coal is widely recognised presenting a secure and economical opportunity for greenhouse gas control.

最便宜和最安全的清洁能源选择之一是使用煤层中的天然气发电和燃料生产，然后将二氧化碳永久储存在枯竭的煤层中。这需要关于煤炭地下行为的详细信息，而这一点是无法获得的。特别是，要求煤对压力、应力和瓦斯相互作用的变化做出方向性和动态响应，这是本项目的主题。对澳大利亚来说，煤层气正迅速成长为一个价值数十亿美元的产业。深部煤中二氧化碳的地理分离得到了广泛认可，为温室气体控制提供了一个安全和经济的机会。
