Australian coal seam gas, for domestic and export use, potentially rivals coal mining in national wealth creation. This project aims to demonstrate that coal seams can function as bioreactors, using naturally present micro-organisms to generate methane. The methane could come from injection of carbon dioxide (CO2) into the coal, creating a sustainable supply of clean burning gas by converting the CO2 into methane. A successful outcome will permit the reuse of wells and associated infrastructure, significantly increasing coal seam methane production and reserves, possibly several fold, as well as reducing the cost of their recovery. The project will investigate the geological, microbiological and engineering requirements to accomplish this.

澳大利亚煤层气，国内和出口使用，潜在的竞争对手煤炭开采在国家财富创造。该项目旨在证明煤层可以发挥生物反应器的作用，利用自然存在的微生物产生甲烷。甲烷可能来自向煤中注入二氧化碳（CO2），通过将CO2转化为甲烷来创造清洁燃烧气体的可持续供应。成功的结果将允许重新使用威尔斯和相关的基础设施，大大增加煤层甲烷产量和储量，可能增加几倍，并降低其回收成本。该项目将调查实现这一目标的地质、微生物和工程要求。
