Underground Hydrogen Storage Simulation Using CMG

With the recent increase of global demand for renewable energies, there are different aspects that need to be investigated. The seasonal fluctuations in renewable energy resources along with the seasonal consumption needs make the storage of any renewable resource energy critical. Hydrogen seems to be an appropriate carrier for storing the energy generated by renewable resources. It could potentially be stored in various types of underground reservoirs such as aquifers, depleted gas reservoirs and depleted oil reservoirs. However, every new field requires thorough investigation before any real-world applications.

The course contains a step-by-step procedure for modelling each of these storage processes. The attendees use WinProp to build basic PVT models for hydrogen storage. They then construct the geological and dynamic model for the process in the target reservoir using Builder. They also introduce different phenomena that are involved in the H2 storage process into the models (such as solubility, diffusivity, etc.). Finally, they investigate the effects the physics involved has on the results.
