That is one of the most intelligent and rational arguments I’ve read in a long time. Well done.It tells me that Toyota is still being stupid about hydrogen. It is ridiculous as a transport fuel. Take 100 kilowatt-hour (kwh) and put into a battery electric vehicle. When you turn on that BEV, you'll get about 90 kwh out of it. That is, the BEV is about 90% efficient.
In contrast, take 100 kwh equivalent of hydrogen, put it into a hydrogen fuel-cell car, and you get about 60 kwh equivalent out -- it is about 60% efficient.
Now consider where that hydrogen comes from that the hydrogen filling station is putting into your hydrogen fuel-cell car. The most common way is to crack water into hydrogen and oxygen by electrolysis. How do you do that? With electricity. The electrolysis process is only about 70-80% efficient.
So, with a hydrogen fuel cell car, you take 100 kwh of electricity and use it crack hydrogen from water. You then get about 80 kwh of hydrogen out. Now you take that 80 kwh of hydrogen and put it into your hydrogen fuel-cell car which is about 60% efficient. 80 * 60% = 48. So you put 100 kwh in at the beginning of the process and only got out 48 kwh of work.
Or, you could just take that 100 kwh of electricity that you would have used to crack hydrogen from water and instead put it directly into the battery of an electric vehicle. You will then get about 90 kwh out.
Hydrogen fuel-cells will never make up a significant portion of the vehicle fleet.
The sad part is if 5-10 years ago Toyota would have stepped up and went strong into EV given their success with the Prius Tesla may not have made it. Now Tesla are so far out in front in terms of battery and management software it’s going to take at least decade for the others to catch up. It is staggering to me that after this last rally Tesla is now the most valuable auto company in the USA, worth more than GM, Ford, and FCA.
