Didn‘t we have a process to electrically synthesize hydrogen out of water?

Electrolysis, it works but it takes a lot of energy to produce, so burning hydrogen from this would be a fools errand.

Wouldn't you spend almost same amount of energy to split water compared to heat produced by burning hydrogen?

Probably more because of entropy: Nature's IRS.

The only way for electrolysis to be greener than fossil fuels is to use renewable energy sources like wind or solar. It wouldn't produce enough to gain much market share in any case. So the oil lobby is pushing to derive it from petroleum, because they're Captain Planet villains.

That's why I said almost.

Yep. Basically gas battery.

But you could technically build huge solar panel areas in deserts and bring that hydrogen to populated areas. Or you could use excess energy from renewables to produce hydrogen, storing at least some of the excess energy for times where renewables produce less.
