I believe the process of extracting hydrogen from other molecules is not considered "making" hydrogen. It was already made by the universe and we're just removing some extra junk that got stuck to it along the way.
By the way, most hydrogen is collected by using a steam reforming process on methane gas. It's MUCH more efficient than electrolysis, but (oh no!) the process emits greenhouse gasses like CO2 (a.k.a "Plant Food")
