Hydrogen Relative Permeability Hysteresis in Underground Storage

Geophysical Research Letters, Journal Year: 2022, Volume and Issue: 49(17)

Published: Sept. 4, 2022

Abstract Implementation of the hydrogen economy for emission reduction will require storage facilities, and underground (UHS) in porous media offers a readily available large‐scale option. Lack studies on multiphase flow is one several barriers accurate predictions UHS. This paper reports, first time, measurements hysteresis hydrogen‐water relative permeability sandstone core under shallow conditions. We use steady state technique to measure primary drainage, imbibition secondary drainage permeabilities, extend laboratory with numerical history matching capillary pressure cover whole mobile saturation range. observe that gas water permeabilities show strong hysteresis, nitrogen as substitute assessments should be used care. Our results serve calibrated input field scale modeling injection withdrawal processes during

Effect of relative permeability hysteresis on reservoir simulation of underground hydrogen storage in an offshore aquifer

Journal of Energy Storage, Journal Year: 2023, Volume and Issue: 64, P. 107229 - 107229

Published: March 30, 2023

Underground hydrogen storage (UHS) in porous media is proposed to balance seasonal fluctuations between demand and supply an emerging economy. Despite increasing focus on the topic worldwide, understanding of flow still not adequate. In particular, relative permeability hysteresis its impact performance require detailed investigations due cyclic nature H2 injection withdrawal. We our analysis reservoir simulation offshore aquifer setting, where we use history matched study effect gas type efficiency. find that omission overestimates annual working capacity by 34 % recovered volume 85 %. The UHS similar natural when using hysteretic permeability. Nitrogen can be used model ignored, but at cost accuracy bottom-hole pressure predictions. Our results advance modeling approaches.

Underground Hydrogen Storage (UHS) has gathered interest over the past decade as an efficient means of storing energy. Although a significant number research and demonstration projects have sought to understand associated technical challenges, it is yet be achieved on commercial scales. We highlight case studies from town gas blended hydrogen storage focusing leakage pathways reactivity. Experience helium serves analogue for containment security two gases share physiochemical similarities, including small molecular size high diffusivity. Natural are also investigated, well integrity safety challenges. Technical parameters identified having adverse effects security, efficiency, reactivity were then used develop high-level site-specific screening criteria. Thirty-two depleted offshore hydrocarbon reservoirs in UK Continental Shelf (UKCS) potential formations based application our The screened fields reflect large energy capacities, low cushion requirements, proximity wind farms, thereby highlighting widespread geographic availability UHS UKCS. Following initial screening, we propose that analysis existing concentrations investigation local tectonic settings key criteria identifying stored hydrogen.
