Leveraging underground hydrogen storage expertise for natural hydrogen exploration: A technical perspective
Abstract
Adapting from mature underground hydrogen storage frameworks provides a viable approach for recovering natural hydrogen. While underground hydrogen storage relies on cyclic injection in relatively homogeneous reservoirs, natural hydrogen extraction requires dynamic, unidirectional production from highly heterogeneous fractured matrices. Despite these operational differences, both systems rely on similar physicochemical principles. This perspective shows that multi-physics simulation workflows used in underground hydrogen storage offer transferable algorithms for predicting gas-water distributions. However, numerical models must transition from evaluating cyclic behavior to analyzing long-term breakthrough dynamics under constant, low advective flow rates. Additionally, thermo-dynamic cushion gas management presents a useful model for handling associated gases in natural hydrogen reservoirs, which requires advanced downhole selective separation to minimize gas-locking risks during production. Successful technology transfer depends on redefining geomechanical and geochemical boundary conditions to couple continuous multi-component phase transitions with hydration-induced bedrock volume expansion. Supported by recent field-scale observations, this recalibration provides an engineering basis for commercial natural hydrogen development.
