It takes massive amounts of energy to generate the hydrogen if you split it from water. If you break it out of methane, it also take a lot of energy and secondary product is a lot of CO2. Then it takes more energy to compress the H2. for all that, it’s not clear that there are other significant benefits over batteries for most applications.
