Lithium being extremely flammable and dangerous in crashes is fake news/misleading propaganda. It is safer than gas. Hydrogen is among the most explosive gases. A containment breach in an accident is not vented easily and may make movie style car crashes a reality.
Hydrogen may form methane in the upper atmosphere after leakage and hence substantially contribute to ghg load even when there is only minor leakage. The precise numbers are not known yet, as far as I know. It is not a miracle gas. For example Jülich is researching this: https://www.fz-juelich.de/en/ice/ice-4/research/hydrogen-impacts-on-the-climate-system
Then you are falling for battery propaganda. There have been many deaths related to battery fires. This has been well documented. Meanwhile, hydrogen deaths are nearly zero. The fuel does not concentrate enough to be all that dangerous. There have been zero "movies style car crashes".
Your study is basically the fossil fuel propaganda I'm talking about. It openly admits that hydrogen is not a direct GHG. So it conjures up a hypothetical situation where it extends the life of methane in the atmosphere. Even if it is real, it goes away once methane emissions stop. It can only be a problem if we fail to stop fossil fuel use.
