There are things hydrogen is good for, and things it is not. Light-duty vehicle use is one of the things in the "not" category.

I think in the next 50 years we'll probably see some yuge advancements in battery tech and ICE efficiency, with most cars being either plug-in electric hybrids or pure electric vehicles. I don't think hydrogen fuel cells are particularly practical.

Shucks... I guess it's settled then.

The production of hydrogen (700 BAR H2) is only one of the many difficulties facing its use in light-duty vehicles.
That said, let me know when the process outlined in the link is up and running.

Even better! Check this site out.

Thanks, I'm aware of that, UMR/MUST is my Alma mater (well one of mine).
Like I said, overcoming the hurdle of production is only one of the hurdles.

Okay, how about the hydrogen production improvements along with improved hydrogen fuel cell technology [also from Phys.org...I love this site!!]

Sure, there's still plenty of hurdles, but it appears they've got some Crackerjack people working on the issues!

Yup, there are promising developments in several areas that are important to allow mass-adoption of FCEVs. However, there is a long way to go, and there are alternative fuels to hydrogen. The need to compress hydrogen to 700 bar to make it practical for transportation is physical issue that cannot be overcome.
Batteries are ahead of FCEVs, despite FCEVs having a several decades head start. That is to say, current battery technology...as current EVs are incomparable to the early EVs of the 20th century. It's also true that PEMFC FCs are closer to their theoretical maximum efficiency than Li-Ion...and Li-Ion isn't even close to the theoretical maximum density for batteries. If you consider the advancements being made in battery technology, and the cost of building a hydrogen infrastructure...it's going to be difficult to make a case for H2 FCEVs in the coming decades. There are still some hurdles with charging infrastructure, of course.
I do think it's possible for both technologies to co-exist, but even after all of the hurdles are overcome, someone still has to build out a multi-billion dollar infrastructure...and you've got to have enough interest in FCEVs to make such a system profitable. BEVs allow for autonomous driving/fueling...and I think autonomy going to completely change the landscape of personal vehicle ownership over the next two decades...something it appears BEVs are more suited to.

Thanks for the test data. I agree, we are probably alright, but I still like the hybrid drive systems that use a small battery and a small gas or diesel, or CNG engine. It seems to make more sense to me to have some way to keep moving beyond a straight battery EV.
