Research suggests hydrogen storage in depleted methane and oil reservoirs possible

computer simulations and laboratory experiments to see if depleted oil and natural gas reservoirs can be used for storing this carbon-free fuel – Hydrogen

studying if hydrogen stored in depleted oil and gas reservoirs will get stuck in the rock, leak out, or get contaminated

found that hydrogen does not stay inside sandstone after it is pumped out, but up to 10% of the adsorbed gas got stuck inside the shale sample

Ho said, this is quite positive for underground storage of hydrogen

when the hydrogen is removed for use, it will contain a small amount of natural gas

not terrible because natural gas still has energy, but it contains carbon, so when this hydrogen is burned, it will produce a small amount of carbon dioxide
