The BIGGEST problem with clean energy

The US has dozens of Pumped Hydro Storage plants.  Yet no new PHS has been built in 30 yrs. There are good reasons for this, both geographical end economic.  Why can’t PG investigate these instead?  

PG talks of H2 and is driving around in an FC.  Yet after decades there are only concept FC cars for sale; there are not FC cars in mass production anywhere in the world. Why? There is no system for mass production of H2, again for good reason as H2 is difficult to transport.  

Indeed in the continental US there are only a handful of H2 fueling stations only in CA, and thus no FC cars for sale elsewhere.  

The useful storage conversation is not a list of possibilities, but a comparison with the king which is liquid fuels.  That 9000gal gasoline tanker truck delivers an hour of Hoover Dam size energy to every other street corner in minutes.  Nothing else comes close.
