it's the least efficient method we currently have of storing electricity. and it's only zero emission if you use a fuel cell
The single advantage hydrogen has over batteries is that the "refueling" is pretty much instantaneous. If charging infrastructure and technology improves, there will be no reason to bother with it anymore.
IIRC, pumping hydrogen is only fast if the pump has a substantial rest between vehicles. Get a line of FCEVs wanting filled and you're looking at filling times not much faster than charging a battery EV.
Also, I’m a physicist that dabbled on the experimental side before going computer simulation full time. I’ve worked with cryogenic instruments and installations.
There’s no fucking way having cryogenic installations in every vehicle and on street corners in a good idea.
From what I understand it's transported in liquid form over long distances (across the ocean for example) but then it's transported/stores in gaseous form.
But theoretically the storage can scale well and it's relatively cheap, albeit who really knows about the price for storage since there are no at scale storages out there yet.
What do you mean by this? However you burn it, it's zero emission, isn't it?
Yes
Burning hydrogen also just produces water as emission
