Description

The DRH350 is a multifunctional flow system designed for hydrogen (H₂) storage applications and dynamic studies of H₂-brine-rock interactions using a sleeved coreholder. This dynamic reactor can simulate the actual flow conditions of injected hydrogen and its interactions with brine and rock under storage conditions.  Rock permeability values can be determined to assess fluid transport properties in a hydrogen storage reservoir.  Following this conditioning phase, advanced analytical techniques (not supplied), including X-ray diffraction (XRD) for mineralogical composition, Scanning electron microscopy (SEM) for microstructural analysis, and Energy dispersive spectrum (EDS) for chemical characterization, can be used to examine mineral dissolution and precipitation by comparing rock properties before and after H₂ exposure.  The goal is to understand geochemical reactions and alterations that may occur when hydrogen is stored underground, including its impact on rock porosity and permeability.  Additionally, the reactor can also be employed to study wellbore integrity in H₂ storage scenarios by analyzing cement-H₂-brine interactions. This study is crucial for understanding geochemical reactions when H₂ is injected into geological reservoirs and assessing its impact on cement properties, ensuring the long-term safety and stability of underground hydrogen storage systems.
