...a catalyst has no effect on thermodyamics. Splitting water requires the consumption of energy accompanied by energy losses to entropy.

A catalyst can change rates, but does not effect the Gibbs free energy of reaction.

Thus in all circumstances, the production of hydrogen destroys exergy. As it is, in almost all cases, energy derived from the combustion of fossil fuels, hydrogen is a filthy fuel.

Efforts to obscure this fact are presented not for the purpose of enlightenment but on the contrary are crude efforts to engage in dishonest marketing to further the interests of the fossil fuel industry, in all cases.
