you do know that the vast majority of hydrogen is manufactured via steam reforming rather than hydrolysis right? there’s a reason why O&G companies are pushing for hydrogen as the next energy source rather than renewables.

steam reforming is methane (ie natural gas) + water -> carbon monoxide + hydrogen

hydrolysis is an energy intensive process. meaning you need to put in more energy than you get out of it. it’s not sustainable at large scale.
