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.

该项目试图了解地下多孔层中的氢气流动。这将通过控制氢的注射和戒断的连续性力学的数学模型来实现。该框架将解释各种物理和生物学机制。零碳氢的地下存储提供了克服可再生能源间歇性的理想途径。该项目的结果包括对两相流量不稳定性对注射和撤离的响应的数学描述，以及对微生物生长在多孔介质中流动的作用的动态见解。预期的好处是提高氢回收的效率和现场选择成本降低。
