The awful physics and dependence on fossil fuels for the manufacture of hydrogen will not be undone by dishonest advertising.
It's a shell game scam.
Right now on this planet, production of hydrogen, a destructive and wasteful exercise when proposed as an energy carrier, promoted here and elsewhere by fossil fuel interests is expected, by 2030 to reach 115 million tons.
The paper to which I'll refer in this post is this one: Reducing Chloride Ion Permeation during Seawater Electrolysis Using Double-Polyamide Thin-Film Composite Membranes Xuechen Zhou, Rachel F. Taylor, Le Shi, Chenghan Xie, Bin Bian, and Bruce E. Logan Environmental Science & Technology 2024 58 (1), 391-399.
I discussed this paper, referring to the awful environmental effects of hydrogen yesterday: Dealing with Chlorine in the Electrolysis of Seawater to Make Hydrogen: Discussion of an Approach.
The energy content of this hydrogen at 120 MJ/kg, will be, should the soothsaying about 2030 prove true, about 13.8 Exajoules on a planet that in 2022 had an energy demand of 632 Exajoules. If we count the cost of compression and cooling along the the thermodynamic efficiency of reforming dangerous natural gas, coal, and oil that is used to make hydrogen, never mind the worse thermodynamic efficiency of economically unviable electrolysis, it is likely that the energy cost of producing this crap will be about 28 EJ, more if one counts the environmental cost of building infrastructure to reduce the awful danger associated with hydrogen.
At current rates, of approximately 2.45 ppm/per year that the accumulation of carbon dioxide is demonstrating, egged on my fossil fuel sales staff promoting greenwashing them with dishonest sequestration scams and hydrogen scams - the rate is rising - "by 2030" the concentration should be about 440 ppm, and still, as they've been doing for half a century, fossil fuel interests will be promoting hydrogen as if it were "green."
It isn't. It's a filthy fuel representing destroyed exergy and increased pollution.
The fossil fuel advertising squad here, seeking to rebrand fossil fuels as hydrogen, is now offering up automobile marketing teams as people to whom environmentalists should refer as purveyors of interest in the environment. This is in spite of the fact that automotive corporations have been huge drivers of climate change for a century.
The effort to make things even worse by hyping the unacceptable, the disastrous, and the filthy should surprise no one. It is unfortunate that dishonest marketing works, but it does so at peril to humanity.
A Giant Climate Lie: When they're selling hydrogen, what they're really selling is fossil fuels.
