I drove 1800 miles in a Hydrogen Car

For those who are interested about how we produce hydrogen, it isn't very ecological for now.
We produce it mainly with natural gas, but also with coal. 98% of hydrogen produced in the world comes from gas or coal. Electrolysis of water is still too much expensive, and our government are investing a lot for reducing this price.
However, even if we success to produce low price green hydrogen, should we use it for cars ? I mean, the available quantity of hydrogen will be necessary limited at the beginning, and there are plenty of utilisation of hydrogen in industry which are maybe more relevent than using it as cars. Using green electricity for making hydrogen for driving, it's not the most intelligent if you can use directly your green electricity in a battery for an electric car (as long as you want to reduce losses of course).

For those who speak French, I recommend the videos of "le réveilleur" about hydrogen, it's probably one of the most complete vulgarisation about it you can find.
