1. The exergy destruction associated with hydrogen means it would be cleaner to just use natural gas as a fuel.

Like natural gas, from which hydrogen is made with exergy destruction (wasted energy), hydrogen is a very dirty fuel, but natural gas has the benefit of being cleaner than hydrogen and having better physical properties, a higher critical temperature, a higher heat of vaporization, and well known compatibility with metals which is sorely lacking in hydrogen.

This scam, while popular, rebranding fossil fuels as hydrogen, is not merely wasteful, but it is costly and destructive to the planetary atmosphere.

Luckily, Green Hydrogen is NOT made from natural gas.... Think. Again. Sep 2024 #3

As usual, some will say H2 isn't green Caribbeans Sep 2024 #2

Yeah, because some of us read science books, not advertising from Exxon. NNadir Sep 2024 #5
