Additionally, underground hydrogen storage in a geologic porous medium offers the largest and most affordable storage capacity for H 2 gas. Nonetheless, the compatibility of H 2 with reservoir fluid in porous media and other safety concerns has to be adequately understood to avoid preventable losses.
