Shell Is Immediately Closing All Of Its California Hydrogen Stations | The oil giant is one of the big players in hydrogen globally, but even it can’t make its operations work here.::The oil giant is one of the big players in hydrogen globally, but even it can’t make its operations work here. All seven of its California stations will close immediately.
The trick isn’t making hydrogen, it’s capturing it, refining it (so that it isn’t mixed with a tonne of air), and compressing it into a pressurised storage tank for later use.
None of that is magic, or even especially expensive. You can do it with stuff available off the shelf to a hobbyist. It’d be a silly way to run cars, but you can do it.
