安全有效地大规模储存氢气 (H 2 ) 是全球能源转型面临的最大挑战之一，只有通过地质层储存才能实现。完整论文中详述的研究旨在解决和讨论地质 H 2储存 (GHS) 的储层工程方面。这项研究基于两个来源：第一，全面的文献综述，第二，作者所在研究所进行的实验和数值工作。
在 GHS 中，储层流体的 PVT/相行为定义至关重要，因为热力学性质会显著影响安全性和有效性。H 2的性质广为人知且已建模，但目前正在研究其与其他气体（如枯竭气藏 (DGR) 中的天然气等原位气体）的反应。虽然理想气体定律可以解释低压下的 H 2行为，但准确描述其热力学性质需要更复杂的状态方程 (EOS)，尤其是当它与其他气体（如甲烷）混合时。
Safe and effective large-scale storage of hydrogen (H2) is one of the greatest challenges of the global energy transition and can be realized only through storage in geological formations. The aim of the study detailed in the complete paper is to address and discuss the reservoir engineering aspects of geological H2 storage (GHS). The study is based on two sources: first, a comprehensive literature review and, second, experimental and numerical work performed by the authors’ institute.
The definition of the PVT/phase behavior of reservoir fluids is crucial in GHS because thermodynamic properties significantly affect safety and effectiveness. The properties of H2 are widely known and modeled, but its reaction with other gases, such as in-situ gases like natural gas in depleted gas reservoirs (DGR), currently is under investigation. Although the ideal gas law can account for H2 behavior at low pressure, accurate depiction of its thermodynamic properties requires more-sophisticated equations of state (EOS), especially when it is mixed with other gases such as methane.
