The project seeks to understand the flow of hydrogen in underground porous layers. This will be achieved through mathematical models of the continuum mechanics governing the injection and withdrawal of hydrogen. The framework will account for a variety of physical and biological mechanisms. Underground storage of zero-carbon hydrogen provides an ideal route to overcome the intermittency of renewable energy. The project outcomes include a mathematical description of the response of two-phase flow instabilities to injection and withdrawal, and dynamical insights into the role of microbial growth on flow in porous media. Expected benefits are increased efficiency of hydrogen recovery and the reduced cost of site selection.

该项目旨在了解氢在地下多孔层中的流动。这将通过控制氢气注入和取出的连续介质力学的数学模型来实现。该框架将解释各种物理和生物机制。零碳氢的地下储存为克服可再生能源的不稳定性提供了一条理想的途径。该项目的成果包括两相流不稳定性对注入和抽出的响应的数学描述，以及对多孔介质中微生物生长对流动的作用的动态见解。预期的好处是提高氢气回收效率和降低选址成本。
