The benefits of tapping natural hydrogen are that it doesn't require a source of energy to produce, and underground reservoirs can hold the gas until it is needed. "We don't have to worry about storage, which is something that with the blue hydrogen or green hydrogen you do; — you want to make it when electricity is cheap and then you have to store it somewhere," Ellis said. With natural hydrogen, "you could just open a valve and close it whenever you needed it."
