Grid-scale underground hydrogen storage (UHS) is essential for the decarbonization of energy supply systems on path towards a zero-emissions future. This study presents feasibility UHS in an actual saline aquifer with typical dome-shaped anticline structure to balance potential seasonal mismatches between and demand UK domestic heating sector. As main requirement aquifers, we investigate role well configuration design enhancing performance selected site via numerical simulation. The results demonstrate that efficiency cyclic recovery can reach around 70% short term without need upfront cushion gas injection. Storage capacity deliverability increase successive cycles all scenarios, co-production water from having minimal impact recovery. also when additional wells are added site; however, distance strongly influence this effect. For optimum spacing multi-well scenario within structure, it attain efficient pressure interference effects at distances uprising phenomenon large distances. Overall, findings obtained approach described provide effective technical guidelines pertaining optimization operations deep aquifers.
