Hydrogen vs. Battery Electric Cars

Good video. And here're the buts that were mostly unsaid in the video:
All industrial scale hydrogen production today is cracking natural gas... so, using fossil fuel as raw material, but also using a lot of energy... typically fossil fuel energy. Electrolysis is not economically viable unless if you have unlimited low cost energy source... so, hydrogen fuel cell is not sustainable nor clean, not ever in the coming years... maybe when there is 2x as much solar power in the world than what is needed... after 20 years or so... and even then... why turn energy into hydrogen and then back to energy? It's very inefficient energy storage. 
Maybe in ships and in aero planes, maybe in polar regions where there is no year around solar and where distances are long and population is thin. It's great technology, but so far it's not economical, nor clean, not efficient. People say the same about battery EV, but battery EV fleet needs two to three times less energy to run... so better put that solar electricity in to car batteries and you can replace the ICE fleet two to three times faster.
