Both are subject to the second law of thermodynamics, and both therefore waste energy, and both depend on fossil fuels, destroying the recoverable exergy in the process of their combustion.

Thus both will continue the trend pushed by bourgeois fools to rebrand fossil fuels as "green," and drive climate change's observed acceleration faster by appeal to dishonest marketing.

The second law of thermodynamics will not be repealed by dishonest marketing, nor is it subject to wishful thinking or appeals to ignorance.

Hydrogen is slightly worse than batteries of course, because of it possesses the third lowest critical temperature of all know gases, embrittles metals, and exhibits are much worse safety profile because of its extremely low viscosity. However both are materially obnoxious and unsustainable.
