The Germans were preparing to invest 8 billion euros in hydrogen.
"These natural gas discoveries can also be used for carbon capture or pyrolysis hydrogen production, which does not consume water resources."
This is the opinion of an expert academic for Turkey's gas discoveries. I think a similar approach is valid in Azerbaijan.
On earth hydrogen is not an energy source in chemical reactions, it is an energy carrier.
It is stupid to convert natural gas to hydrogen to be used as fuel in transportation industry since you lose a lot of the energy in the conversion process. You would not gain environmental benefits either since you still have the same CO2, which technically could be captured to be stored in under ground facilities but that cost a lot of energy and money.
Natural gas is best used as LPG/LNG in transportation industry. But if you really need to convert it then it would be better to convert natural gas to a liquid fuel like diesel instead of hydrogen as we have an infrastructure for diesel. Storing and distributing hydrogen have a lot of technical problems.
Hydrogen is of little value unless you have direct use of hydrogen in your industrial product/process.
Also, the water usage argument is weak argument since water is not consumed but recycled.
Only time hydrogen can be considered as a good energy carrier is in two scenarios.
1. You have a very very very large overabundant energy production from renewable sources like solar that you can not use.
In this case, converting this overproduction to hydrogen could be potentially useful. In reality, even this is stupid for various reasons since you lose most of the energy.
2. You have a 4th generation gas cooled high temperature nuclear reactor which can use high temperature pyrolysis of water as a byproduct of the nuclear reactor. Problem is that nobody have such a rector yet.
