There are two practical ways to make hydrogen:
Split water molecules via electrolysis. This is thermally inefficient and not cost-effective at scale.
Strip hydrogen atoms off of hydrocarbon molecules, usually natural gas. It's much cheaper. Unfortunately, the leftover carbon atoms leave the process as CO2. AFAIK all commercially available hydrogen is made this way.
Damn, thanks for the info, I always assumed it was just splitting water
