There is an interesting point of overlap between hydrogen energy storage
and battery energy storage. The nickel-hydrogen battery has been used
for decades. They are capable of very long life, and high energy
density, and can work in extreme environments. The International Space
Station uses them. The hydrogen is stored in a pressure vessel, like the
tank for a fuel cell.
The nimh cell is a variation of the nickel-hydrogen cell. Rather than
being stored in a separate pressure tank, the H2 is adsorbed onto the
spongy metal hydride electrode inside the cell itself.
