Visual Presentation L1 Underground hydrogen storage (UHS) has the potential to overcome the infrastructure and safety challenges of large-scale hydrogen storage, support long-term supply security and decrease delivery costs through economies of scale. Depleted hydrocarbon reservoirs and saline aquifers are likely to be significant contributors to UHS capacity in Australia. The principles of subsurface hydrogen storage in porous reservoir rocks are based on experience from both natural gas and carbon dioxide storage projects. However, as field-scale testing is required to demonstrate and mature the technology, a pre-feasibility study of the potential for an early UHS demonstration at the Otway International Test Centre (OITC) has been undertaken. Pre-feasibility studies have shown that while the characterisation of the subsurface storage reservoir is the most important aspect of the site-selection process, above-ground factors, such as facilities design, the logistics of hydrogen supply and the regulatory environment, significantly affect project design. Existing technologies require only minor adaptation to provide the surface infrastructure for a UHS project, but the logistics of hydrogen supply may be a significant factor in the scope of a demonstration project.
