Hydrogen vs. Battery

The author is not particularly well informed, but perhaps that gives a hint at public perception.

Yeah, right. No one is going to install infrastructure without vehicles to use it. The hydrogen advocates have the very same problem but much worse.

Actually the comment section pretty well covers it already. Most ABG readers get it.

I did, but it was immediately buried in a huge pile of similar postings...

You can return home with the electric scooters currently on sale. Same with the Tesla Roadsters (out of sale). That takes some time for charging, of course. The Fisker (not fully acquirable at EUR 120k) and the 100% up-to-job Volt do the return trip without limitations or anxiety.
The models from the big manufacturers (likely never on sale) get hauled home by flatbed trailers...

Many thanks to Eberhard for letting me ride shotgun in the Roadster.

Beautiful countryside. Made me want to jump in the car and find some mountains.

Eh???

The fuel cell system uses a lithium-ion battery pack, and the hydrogen gas is stored in 10 tanks, all 150-psi,

 

[dpeilow]

Yeah I thought that seemed unlikely too.

No way that's a 3 min refuel then.

That was an ad, not a legit article.

The B-Class F-CELL converts compressed hydrogen into electricity, and gets a range of about 240 miles per charge. The fuel efficiency rating is equivalent to an average of 55 miles per gallon.

This implies storage of 4.4 GGE ~ 4.4 kg of H2

607 Wh/mile tank to wheels.

 

[dpeilow]

607 Wh/mile tank to wheels.

No more like 1000+ Wh/mile grid to wheels.

 

[stopcrazypp]

I think the number of tanks (article says 10) is also incorrect. A high res cutout of the F-Cell shows 3 hydrogen tanks:

The numbers are also wrong. It mixes the European range (240 miles on Euro cycle) with the EPA numbers (55 mpg). The EPA range is about 190 miles and tank capacity is 3.7kg @ 700 bar.
