Improved hydrogen geological storage via zeta potential measurements

氢气是一种清洁燃料，有可能通过完全脱碳来彻底改变能源供应链。预计到2050年，全球氢气市场将增长50倍，总额达到16.3万亿澳元。然而，氢经济的关键障碍是氢的储存，因为氢是高度挥发性的，可压缩的和易燃的。地下储氢，即在沉积地质构造中储存氢，是解决这一问题的潜在选择。在这个项目中，我们将提供建立氢地下监测技术所需的基础数据，并开发相关的大规模模型，以预测地下储氢的效率和安全性。

Hydrogen is a clean fuel which has the potential to revolutionize the energy supply chain by complete decarbonisation. An estimated 50-fold increase in the global hydrogen market is expected by 2050, totalling AUD$16.3 trillion. However, the key barrier to a hydrogen economy is hydrogen storage, as hydrogen is highly volatile, compressible and flammable. Underground hydrogen storage, i.e. storage of hydrogen in sedimentary geologic formations, is a potential option to solve this problem. In this project we will provide fundamental data required to establish hydrogen underground monitoring techniques, and to develop associated large-scale models with which underground hydrogen storage efficiency and security can be predicted.
