“…While a specific case example of the selected database of DGF from the UKCS was used throughout this study, the general approach for microbial risk categorization is widely applicable to other DGF around the globe. This study presents a new paradigm for characterization of the potential role of microbial communities during geological hydrogen storage that should be included in existing site selection criteria for this technology (e.g., [77,78]).…”

<p>Climate change, triggered by a continuously rising use of carbon based energy sources, is a global concern. Geological hydrogen storage, e.g. in depleted gas fields or saline aquifers, can overcome imbalances between supply and demand in the renewable energy sector and facilitate the transition to a low carbon emissions society, in this way mitigating climate change. However, a range of subsurface microorganisms utilise hydrogen which may have important implications for hydrogen recovery, clogging and corrosion. We created a novel, globally applicable risk categorization tool based on the published environmental growth constraints of all major hydrogen utilizing microbes (hydrogenotrophic methanogens, hydrogenotrophic sulphate reducing bacteria, homoacetogens and hydrogenotrophic dissimilative iron reducing bacteria) and on reports of paleosterile subsurface environments. Application of the tool to 75 depleted or close to depleted gas fields on the UK continental shelf showed that 9 fields fall either within the &#180;No Risk&#180; category with temperatures >122 &#176;C, making them the ideal candidates for hydrogen storage from a microbial risk point of view. Hydrogen storage in the 35 &#180;Low Risk&#180; fields with temperatures >90 &#176;C or the 22 &#180;Medium Risk&#180; fields with temperatures >55 &#176;C and salinities >1.7 M NaCl will require the careful characterization of the microbial community composition to assure that hydrogenotrophic microorganisms are not present. We recommend against utilising depleted gas fields with temperatures <55 &#176;C which are at high risk for adverse microbial effects.&#160;</p> <p>Results were mapped and aligned with centres for renewable energy production and out-of-use pipelines suitable for repurposing to transport hydrogen. This showed that No Risk or Low Risk depleted gas fields in the Southern North Sea are the most suitable candidates for hydrogen storage. Our results advise site selection choices in geological hydrogen storage in the UK. Our methodology is applicable to any underground porous rock system globally.</p>

“…They also require less capital and operational cost as the existing infrastructure can be easily repurposed to operate with H2 [454,455] (refer to previous discussion in section 3). Moreover, H2 storage in these types of reservoirs is safe as demonstrated in recent modeling and numerical simulation studies [417,422,461,426,456,457,457,458,[458][459][460].…”

“…An important factor in reservoir simulation is the operation strategy, which may cause different simulation results. In Okoroafor et al's study [34], they used methane as a cushion gas and observed a decrease in hydrogen's production rate and an increase in methane's production rate with increasing injection and production cycles. In contrast, our simulation demonstrated an increasing hydrogen production rate and a decreasing methane production rate.…”
