H2 is (as we all know) a dead end until significant innovations are made
and its energy efficiency remains questionable (read: the fuel is likely
to remain non-competitive) no matter how much the fuel cell gets
BTW, FCV is still an electric vehicle. It should be called FCEV. Only
the energy storage is in H2 instead of in batteries, but you need a fuel
cell to get the power out again so instead of just a controller to tap
into the battery power, you need the series of H2 tank - fuel cell -
(often intermediate battery storage for power peaks and for regen
braking) - controller - electric motor.

So, when (probably not "if") the FCV line fails, just rip out the
clumsy fuel cell setup and H2 tank, pop in a good battery bank and
off you go in your new EV.

Subject: Re: [EVDL] EVLN: Toyota Drops RAV4-EV-gen2, shifting to h2

Without wanting to get into a detailed FCV discussion here, I'm puzzled.

1.  Last I heard a practical FCV was not possible until some Brand New
Stuff was invented, and no one knew if/how/when that would happen.
2.  Last I heard there was no way to create H2 that was anywhere near as
efficient as just filling a battery with the same energy.
3.  Last I heard FCV fueling infrastructure was wildly more expensive
EV fueling infrastructure.

I'm trying to understand the business case for pursuing FCVs instead of
seemingly more promising path of furthering advanced lithium
 The only plausible reason to pursue FCVs that I can think of is that
too easy for an upstart manufacturer (like that pesky Tesla) to become
EV manufacturer.  The fact that FCVs are inherently more complex and
require far more in-house R&D are barriers to entry for new players.
even that would require winning the hearts and minds of the driving
and I don't see how the user experience is significantly better.  Heck,
don't see how you could make an FCV that would gain more market
than Toyota's own hybrids.

I'm trying hard to make sense of this.  Where's the return for Toyota?
there something new in FCV development that I missed?
