did you know H2 can explode?

ROFL - more expensive than gasoline per mile - and similar GHG emissions at the refinery to make H2 vs. burning gas in an ICE - yeah that's a huge win! {sigh}

Here in Ontario Canada, off-peak power is $0.068 per kWh, so double the savings again if compared to gas or hydrogen.

The whole purpose behind Hydrogen was to keep the production and distribution in the hands of the same clique: the Oil companies!
It does not make any sense to use Hydrogen to power a vehicle: highly dangerous, expensive and totally impractical.

The big problems with H2 are 1) it's a low density gas that is difficult to liquify or compress, and 2) it must be manufactured. Overall, the ramifications are now clear - compared to battery electric, hydrogen is a loser for cars. It's time as a useful distraction is nearly over.
But here's an idea: combine four atoms of hydrogen with one atom of carbon, which yields a gas that is much easier to compress. Actually, you don't have to manufacture this gas - it comes up out of the ground in many place! Yes, methane contains carbon, but only half as much as gasoline.
[It amuses me to look at things from different perspectives. A marketing person could come up with a way to sell natural gas with the slogan "Hydrogen you can use!"

hmmmm
hmmmm
Hydrogen stand operator Sung said while refuelling itself takes about 5-7 minutes, the next driver must wait another 20 minutes before sufficient pressure builds in the storage tank to supply the hydrogen or the car's tank will not be full.

The H2 station a couple miles from my house has been down for weeks. There is one a couple more miles away that is supposedly up occasionally. A friend of mine leases a Mirai. Saw him last weekend, and he was telling me about where they do and don't have H2 around the Bay Area. He constantly watches the web site showing availability, and when one of them shows green he heads over there ASAP. What a PITA.
For my part, I'd rather take a few seconds to plug my car into the grid in my driveway as needed.

- hard to handle safely
- complex to refine
- generates GHG's at refinery point
- normally fossil fuel based
- expensive to transport and store
- way less efficient well to wheel than BEV's
- not actually that fast to recharge for back to back fill up session
- FCV are expensive to manufacture
- H2 based ICE's are still mechanically complex
- and leaves the fossil fuel industries business model mostly intact along with environmental impacts
- H2 isn't that cheap per/mile
- it is zero GHG emissions at the tail pipe (H20 is it's only by product).
- should be as fun to drive as a well designed BEV as it still has instant EV torque/power

The Japanese Government is all in on Fuel Cells, one of the reasons hypothesized the Japanese automakers are behind in EV tech. Until lately , the Toyota and Honda have stated BEVs are not they way forward but fuel cell is. I guess reality of governmental regulations around the world and the lack of hydrogen infrastructure have them changing course with Toyota and Honda making big battery supply deals lately.

Studied fuel cells for transportation in grad school in the early 2000's. Toyota has been heavy in fuel cell development since the 90s. Long story short, I came to the conclusion that fuel cells are not a good choice for transportation use. Stationary power gen? Sure, but not transportation where it's low energy density is a huge problem. Storage is an issue being the smallest molecule in existence; it likes to leak past every seal known to man. Making it, storing it, transferring it, all not good for transportation applications.
My guess as to why the Japanese were/are so heavily invested? They were maybe thinking of using nuclear energy to generate hydrogen. They don't have much in the way of natural resources, so making hydrogen from water using nuclear power could solve one of their energy issues. Just a pure guess.

what is the difference between diesel fuel in California vs Nevada (or anywhere else for that matter?)
(assuming you filling up at a Costco or some other top-tier location, please skip over explaining any of the bio-diesel junk that should not be feed into our CD's)

Hydrogen has already lost. BEVs are improving too quickly, and PHEV do a much better job as a transition for demographics that can’t adopt BEV yet with our current infrastructure.
plus, lawsuit in America ? lolz. Hydrogen would need congress to pass an immunity waiver like gun manufacturers. Go see South Korea. Stations keep blowing people up.

The BIG PROBLEM with Hydrogen is that it REQUIRES an infrastructure to fuel vehicles.
EV's DO NOT require a charging infrastructure (contrary to what some would like you to believe). 70% of EV owners simply charge at home overnight. Much of EV's current success was built on home charging. I'm on my third EV (with the Taycan presumably being my fourth) and I've never even seen a public charging station.
If you have electricity, you can charge an EV. (even a 120V outlet) If you don't have a hydrogen fueling station you are done...
