The end of gasoline/diesel powered cars?

In case mass is not critical Na may replace Li due to almost no limit for presence and cost.

Efficiency is only matter in overall industry.

Climate control I meant simply HVAC as one of the main consumer of the generated electric power. To spend it for hydrogen generation does not make any sense.

BTW, managing hydrogen is very difficult and dangerous business. Recent FT article is good one from real world.

In majority of applications like transport or mobile phones the mass is critical. Also the size is also larger than Li-ion.

IF...... smart guys have done this commercial and all not true. Existing natural gas distribution infrastructure unable to handle hydrogen flow. Simply, H and carbohydrogens have absolutely different permeability specs. Just check handbooks and you will find that gear used for natural gas is not suitable for H. So simple.

Yes. Dimensions and mass is bigger for Na but for grid storage is not. Mobile applications Li is more than enough.

You've got to be a subscriber to see it.

My personal view is that Hydrogen technology will replace diesel for ships and probably for airplanes. For grid storage Na is more than efficient element to switch from coal/gas/oil/nuke to renewable. 

No one solution for all cases. 

Nature developed raw materials for looong time and we almost used it in something like for 200 years. But Sun is ideal source of life on our blue planet and emits almost 1KW onto each 1 sq m on sea level!!! We never ever need and use energy such dense. Matter is just smart way to use this present of Mother Nature.

Do I understand it right that despite the widespread stereotype a hybrid and electric vehicles are not a real threat to oil and gas producing countries? Because all this hybridization and electrification will take many decades and...

1) A new huge electric generating power plants have to be build and expended.  2) An electric infrastructure have to be modified and expanded.                          3) It will take (many) decades to switch all the automotive industry to hybrids and electric cars production.                     4) Hybrids and electric cars will become more and more common among the passenger vehicles, but among pickups and trucks they will spread more slowly. And even more so among plains, ships, agricultural and construction machinery, trains, etc. For now there no even serious plans to build an electric plains ever...                                                              5) Signifficant amount of oil in the World (around 40-50%) is used for petrochemical needs rather than motor fuels. This is just in a few developed countries the portion of motor fuels reach 75-80%.

So, in time when all this changes will start to affect oil market seriously, there will be severe shortage of oil in the World already and some modern oil producing countries like Russia, Mexico, Norway may leave the title of oil producing powerhouses. If there will be no oil saving techniques in 50 years, oil prices will get so high and oil will get so scarce that people throughout the World will be simply forced to abandon hydrocarbons as an energy source completely. So, paradoxically the technologies like hybrid vehicles help to make hydrocarbon era longer than it otherwise would be. If all the modern vehicles would have the same fuel economy as they did in 1970-th, there will be no more conventional oil anywhere in the ground already. And anyone would use biofuel.
