Hydrogen downside

Hydrogen fuel has a global warming effect I’ve only seen once mentioned in the press.

Hydrogen escaping into the upper atmosphere reacts with hydroxyls. It is the hydroxyls that partly reduce the accumulated methane in the atmosphere, and methane is 22 times more powerful as a global warming gas than CO2.

Without the hydroxyls to remove the methane, the global warming effect would be greater. I’m not a proponent of global warming theory but every proposed solution has a drawback.
