I have studies the economies and uses of hydrogen, it is where O&G companies are trying to move to and its still not great.
Firstly it has to come from renewables unlike blue hydrogen that comes from natural gas. If we ever come to having too much gas I suggest using that, nice thought there mind you lol.
Solar power works only during the day so 50% of capacity potentially lost. Yes you can add wind turbines to make it 24 hour production but your costs are higher. Still doable via solar but plant producing hydrogen cannot operate 24/7.
Hydrogen transportation is best done as ammonia then converted back to hydrogen as hydrogen is not as compressible as ammonia. Ammonia plants are not cheap so more CAPEX. If can be done by pipeline but a new one made of materials not attacked by hydrogen is needed.
Hydrogen rots the existing gas pipes we use currently unless its the new plastic ones so infrastructure would need upgrading to transport it. We can use upto 10% mixed with our normal gas supply safely however, this is the old town gas we used to use. Above that wont work.
I have concluded my research by assuming hydrogen will happen simply because batteries are not suitable for all machines, eg look at what JCB are doing also planes need a bigger bang than a battery can give for its weight issues., I should add ammonia can be used to power a plane. So hydrogen is coming it will off course be more expensive than oil and gas but that does not matter to the green fanatics that run this world as its us that pay.
