Even from an environmental perspective, hydrogen cars make little sense. Currently, hydrogen is a petroleum product. It's typically made from natural gas, and this process emits plenty of CO2 (plus all the pollution inherent in oil extraction). You can make hydrogen cleanly by using renewable electricity to power electrolysis, but nobody is doing that currently and the efficiency is terrible. You'd need three times as much generating capacity to power a fleet of hydrogen vehicles as you would to power an equivalent fleet of EVs. I really can't figure out why Toyota is pushing them so hard. |
