The coupled non-isothermal, multiphase-multicomponent flow and reactive transport simulator OpenGeoSys–ECLIPSE for porous media gas storage

Utility-scale subsurface hydrogen storage: UK perspectives and technology

“…The results of this mixing can be a heavily contaminated extracted product, generating additional costs for necessary separation processes. The degree of this mixing requires accurate model descriptions simulating thermo-hydro-mechanical-chemical processes and are thus the current focus of many research groups [33,42,52,60]. "HyStorPor" is the UK's current program funded by the EPSRC conducted at The University of Edinburgh with the goal of investigating this at lab scale and the development of flow modelling approach at the utility-scale [61].…”

“…Tarkowski and Matos et al both suggest formations utilised should be in the region of 500-2000m bgs [6,22]. However, systems modelled by Sainz-Garcia et al, Pfeiffer et al and Pfeiffer and Bauer focus on the sections between 450-700m below surface [8,54,60]. Although these modelled reservoirs provide valuable insight, candidate reservoirs would most likely be in the >1500m bgs to allow for hydrogen to be stored at a meaningful density.…”

“…OpenGeoSys-ECLIPSE couples the open source Galerkin finite-element method OpenGeoSys, a software capable of processing THMC processes in porous and fractured media, with the ECLIPSE simulation suit, a commercially available multiphasemulticomponent flow software produced for reservoir engineering [60]. This was accomplished by Peiffer et al where it was used to produce the first utility-scale model of THC processes hydrogen injection/withdrawal in a typical water saturated anticline structure [60]. A simplification of the biogeochemical processes was reduced to only considering methanogenesis; this is considered too simple to infer the impact of conversion [60].…”

It was determined that with each cycle reservoir temperature would increase, though this would be dampened through the caprocks conductive transmission [60]. Additionally, it was found that the impact of thermal change through expansion would have insignificant effects in comparison to that through hydrogen injection/withdrawal [60].…”
