Mr Gus,

Quick answer - salt water = hydrogen gas, chlorine gas and a waste soup of lesser salts and minerals that's is probably too costly in energy terms to exploit and expensive to dispose of, hence the hydrogen industry preference to crack natural gas.

The trouble with using electrolysis to generate hydrogen from seawater is that you will then get copious amounts of chlorine along with oxygen produced at the anode, and that's a nasty mess to sort out, along with a soup of other salts to get rid of.

Look what just turned up in Norway. I don't think its for sea water but interesting this is still type of thing being researched and trialled.

So the world's largest hydrogen electrolyser produces up to 100kg of H2 per hour. So 2400kg per day.
How much energy does it consume to do so I wonder?
How many Mirais would that fill up?

We need green hydrogen for many many industrial processes. Just not for ground transport.
