Interesting. I didn't even know these existed. So the big question. I live in the US. Should I save up for an electric car or save and wait for a hydrogen car?
It is difficult to store, expensive to produce, expensive to run. Zero emissions and range are the only things I can see that can make a difference.
You see, people are complaining about electric infrastructure even in California. And all it requires is a beefy power outlet - to reduce the charging times, as you can use even a standard outlet if you can wait. You can imagine how that will go with hydrogen.
The article says nothing about the technical challenges. Presumably, they are storing hydrogen as gas. What about hydrogen embrittlement? Also, I don't think drivers would be very happy to know that their fuel tanks are slowly but surely letting their hydrogen escape. The atoms are too small, they can escape from anything.
Twenty or ten years ago hydrogen seemed like a pretty good way to go, and these products are the end result of projects started way back then. But batteries have pretty much leapfrogged hydrogen in every way, and I can't see hydrogen staging a comeback.
Recharging speed depends on how you're using it. On a road trip, hydrogen wins (if the stations ever get built out). For daily driving, electric wins, because the effective recharging time for plugging in overnight is zero, since you're not waiting for it.
Both are likely to improve for batteries much more that for hydrogen, too.
If you don't need a car now then the question asked today is also redundant, since you'd evaluate the benefits in the future, not now.
Right now you have three viable choices: petroleum, diesel, and electric. A few limited areas also offer natural gas, bio-fuels, etc, but they're niche to set markets.
