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.
I can put two electrodes in salt water and run it off an old power brick and generate hydrogen. It’s not efficient, industrial hydrogen isn’t primarily made that way (it mainly comes from oil instead), and hydrogen has a list of other problems, but it can be done.
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.
