Fluid dynamics of underground hydrogen storage

该项目旨在了解地下多孔层中氢气的流动情况。这将通过控制氢气注入和提取的连续介质力学的数学模型来实现。该框架将考虑到各种物理和生物机制。地下零碳氢储存为克服可再生能源的间歇性提供了一条理想的途径。该项目的成果包括对两相流动不稳定性对注入和提取的响应的数学描述，以及对微生物生长在多孔介质中流动中的作用的动力学见解。预期的效益是提高氢回收效率和降低选址成本。

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.
