Not really. There are plans for hydrogen plants. The vast majority is "blue". Secondly what are the chances that an oil company is going to make green hydrogen?
The renewables aren't the problem. The cost of capturing energy is the problem. If hydrogen takes 3-4x the energy then that's 3-4x the land with 3-4x the solar and/or windfarms at 3-4x the expense. Do you not see the problem?
No it isn't. Scientific studies suggest the impact on the atmosphere might 12x worse than releasing CO2.
Lithium isn't the only battery material. Nor I daresay even if it were, that the safety risk is anywhere near as bad as driving a train with a hundreds of kgs of hydrogen on board
Lithium isn't the only battery material. There are numerous battery chemistries in existence. It might even be that some less dense chemistries like sodium ion would be viable.
Which is why I clearly I suggested a progressive approach. Switch from diesel to biodiesel, start building hybrid trains where the motor and tender are almost separate things and where the source of power can be 2 or 3 potential inputs - diesel, electrification, battery. And where rolling stock can use solar to reduce consumption further.

Sorry to burst your bubble. Australia, Africa, take your pick, both have huge multimillion dollar green hydrogen plants being built. Like the 1GW North Queensland hydrogen project currently in contract.
Again see above
Right… that is bullshit. Plenty of real world studies and events HAVE occurred and the toxic release is not a maybe flip flop study. https://www.nature.com/articles/s41598-017-09784-z

Don’t like papers in nature? This guy is a bit of an asshole but he is not wrong at all and reports on the recent event/s Watch it to the end. https://www.youtube.com/watch?v=H7l4wR1zhbc 4. Sure but none are here and more competitive or suitable for application (like compressed air) the leader is clear and underwhelming. Here we need to understand promises of development realistically don’t occur more often than do. 6. I won’t knock on biodiesel as we need a solution, something but we can’t create religions on one in development “potential” more likely to fail than succeed
