I used to drive a hydrogen car once in a while a few years ago. It was nice to fill the car in a few minutes and get about 300km of range, but that was it. With the hydrogen you have so few refueling stations, they are very expensive, that range anxiety is a thing. To not improve things, reliability is very poor. My work had a hydrogen refueling station on its parking. It was often broken and actually a bit scary to…

Re: After many false starts, hydrogen power might now bear fruit
#33Main points: 1. The only hydrogen produced from electricity is ecological. Carbon capture doesn’t work today. 2. The hydrogen from electricity is expensive, though as wind and solar get exponential cheaper, we will end up with spikes excess cheap electricity (negative prices today or disconnecting plants). It makes sense to produce hydrogen during those spikes. 3. Cars on hydrogen don’t make sense at all. The massive…
1 kg of (electrically produced) hydrogen costs more than 1000 gallons of desal. (1 kg of hydrogen would make a few gallons of water)
Well that's just not at all true. Hydrogen by electrolysis costs https://www.nrel.gov/docs/fy04osti/36734.pdf

And you always have full (trip) range every morning with an EV. Yes, filling up in 5 minutes is better than 20. Never needing to fill up is even better.
And which technology allows for that? The cars "running on water" that new age alien enthusiasts are always on about?

#35Earlier quoted context omitted.
sounds like Iceland would do well to export hydrogen from electrolysis
Transporting hydrogen is expensive. It also has a tendency to leak.
But I mean, that has to be a limitation of current technology, right? There has to be engineering solutions that we can devise to make it as safe statistically as for example gasoline transport?

The issue of charging was also there with BEVs, until Tesla straight up built a huge network of superchargers. The players in hydrogen say they will do the same. But for personal vehicles, hydrogen won't math out, it's greatest advantage is its energy density for trucks. It's for long range trucks that we will see hydrogen first. Green hydrogen will act as energy storage, big renewables grids can dump excess into gre…
Re: After many false starts, hydrogen power might now bear fruit
#37Hydrogen production is almost entirely produced from fossil fuels currently. Its not really a low carbon energy source unless electrolysis can be made much more efficient. Its a shame this article didn't examine the production side of hydrogen.
How is that different from criticism of BEVs when they’re used in areas with coal-based electricity?

Isn’t the last 1/3 of the article about the differences between grey, blue and green hydrogen?
