UHS Benchmark Study

This benchmark study establishes an underground hydrogen storage (UHS) scenario to evaluate the capabilities of various simulators to predict hydrogen-related processes.
The scenario itself comprises a semi-artificial grid representing typical sandstone formations. The gas storage facility is operated using a single well located at the center of the formation. Initially, the formation is saturated with natural gas in a state of hydrostatic equilibrium. Periodic, pressure-controlled injection of hydrogen-containing gas transforms the formation from a gas reservoir into an underground hydrogen storage facility. Subsequently, four regular storage cycles—each consisting of three months of injection and production with idle periods—are performed. This study examines two cases with varying hydrogen concentrations blended into the natural gas stream (10% and 80% H2).

The benchmark scenario is provided in Schlumberger Eclipse simulation format, including the relevant files such as the grid, properties, and schedule. Additionally, the commercial simulator Schlumberger Eclipse and the open-source simulator DuMuX were compared in an initial commit. The corresponding results are included in the current repository to facilitate better comparison of future commits.

Therefore, we invite you to simulate this study yourself and compare the present results with other open-source or commercial simulators. The .zip archive can be downloaded here.
