Electric vehicles are much more economical and practical to implement.
They are here now! The electricity infrastructure is in place but needs to
be strengthened.
There is no H2 infrastructure in place and it would be expensive to
build to make it as convenient as electrical outlets which are everywhere.
Solar panels on roofs of homes and buildings will provide a distributed
energy system. MI State U has developed flexible shingles but they need to
be printed on flexible material 1 m x up to 5 m to make them economically
practical.
Wind turbine electricity generation has proven to be practical. They
can be built now if elected officials would get out of the way and let them
be built where the wind is such as along the northeast cost of the US and
on mountain tops like some are doing in ski areas.
Battery development is in its infancy.
Elected officials are the impediment.
The SI is used in the electricity industry now; however, its use needs
to be refined.

Subject: [USMA:43355] Hydrogen vs. Batteries
If hydrogen is the car fuel of the future, it will be sold in kilograms, a
major (and stealthy) coup for NIST and US metric advocates. However,
while gasoline will eventually go away, H2 might never catch on due to
advances in battery technology, which could make electric cars more
practical. Sadly, my guess is that this will happen, but here's an
article arguing otherwise:

and another:

On the flip side, there's a company called EEStor in Texas that claims to
have developed an ultra capacitor that will power a car for decent range,
and unlike batteries can be recharged in minutes and will never wear out.
If that's for real (no prototype has been demonstrated) goodbye H2 as the
car fuel of the future and a fleeting victory for the kg.
