You think the toxic (deadly) lithium thermal runaways that can’t be stopped are somehow better? No. They are worse and a deadly underground carpark disaster waiting to happen.

Yup, all those trains waiting to explode in carparks. Nor are we developing better batteries that don't have these problems. Nope, just leaving things exactly as they are.

Not enough lithium in the world to supply the global suv market . . .

Even if lithium was our only battery option, this is just plain wrong. People misunderstand what "reserve" means in mining. It's not the amount of something that's available to be mined. It's the amount that is available profitably under current economic conditions. Both better technology and other shifts in the market mean more reserves "magically" open up.

Oceanic lithium mining may already been commercially viable, and the amount of lithium we can get from that is basically unlimited. On the lab side, there's a promising string-based evaporation method, which would substantially reduce costs and environmental footprint--exactly the sort of tech that makes more reserves open up. It still needs to be demonstrated at scale, but the strings involved don't use any exotic materials or have any difficult production.

1. 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?
2. 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?
3. No it isn't. Scientific studies suggest the impact on the atmosphere might 12x worse than releasing CO2.
4. 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
5. 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.
6. 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.
