The project aims to improve methods to generate power from geothermal energy. Extraction of heat from deep earth is promising but so far inefficient. Heat is transferred when water is pumped underground, but recovery of heat is low and much water is lost. This project aims to investigate carbon dioxide (CO2) as an alternative to water. There are excellent prospects of relatively efficient recovery, and any loss of CO2 in deep-earth geothermal reservoirs is beneficial because it represents permanent sequestration of carbon. The project plans to investigate the evolution of fluid-flow systems, recovery rate, long-term injectability, and mechanical-flow behaviour. Findings are expected to provide practical information on the geomechanical viability of this green power option.

该项目旨在改进利用地热能发电的方法。从地球深处提取热量是有希望的，但迄今为止效率低下。当水被抽到地下时，热量被传递，但是热量的回收率很低，并且损失了很多水。该项目旨在研究二氧化碳（CO2）作为水的替代品。相对有效的回收前景很好，而且深地热储层中二氧化碳的任何损失都是有益的，因为它代表着碳的永久固存。该项目计划研究流体流动系统的演变、采收率、长期可注入性和机械流动行为。预计调查结果将提供实用信息的地质力学可行性，这绿色电源选项。
