There are several reasons why I doubt the future of hydrogen fuel cell cars. The biggest problem is, where the hydrogen does come from:<p>- currently almost all hydrogen is produced from natural gas, releasing CO2 in the process.<p>- creating hydrogen via electrolysis is possible, but very energy intensive, using up much more electricity than it releases in the fuel cell<p>- in any case, there is further energy used for compressing the hydrogen.<p>So, in total a pure electrical car easily drives 3 times as far as a hydrogen fuel cell car with the same amount of input energy. This is going to put hydrogen cars at a big disadvantage to electrical cars.<p>On the other side, electrical cars are getting to the point where the advantages of hydrogen cars are getting moot. The range is pretty close, and with fast charging the &quot;refuel&quot; does not take much longer as with hydrogen cars - but you normally can charge them overnight and not have to recharge them on the road in day-to-day business.
