The hydrogen home refuelling station works via an electrolyser which produces the gas from water and electricity.

When hydrogen is sent into the solid, the reaction creates enough heat to make a filling station very uncomfortable.

Such materials could be used to make hydrogen cartridges that would slot into fuel-cell cars, making refuelling as simple as pulling into a filling station and swapping an empty cartridge for a full one.
