Good Question Toni, but no one has said anything about H2.
No, I think they are talking about common or garden variety
hydrogen.
It would be the same as hydrogen used for cars in US & Japan.

H2 is common or garden variety hydrogen, Belly. It's a diatomic gas... they're all diatomic except for the nobles.

Sorry, Bazz, not Belly. Nevertheless, the point still stands: hydrogen is H2.

‘ OH COME ON..YOU ALL BELIEVE IN GLOBAL WARMING AND THE CARBON TAX ‘ YOU ARE AUSTRALIANS!!

INTERESTING.

Hmmm - saving the planet - here we go!

Here's a small sample of how many coal plants there are in the world today.

The EU has 468 plants building 27 more for a total of 495

Turkey has 56 plants building 93 more total 149

South Africa has 79 building 24 more total 103

India has 589 building 446 more total 1036

Philippines has 19 building 60 more total 79

South Korea has 58 building 26 more total 84

Japan has 90 building 45 more total 135

AND CHINA has 2363 building 1171 total 3534

Here come our AUSTRALIAN politicians that are going to shut down our 6
remaining plants and save the planet !

Toni Lavis- I've learned to be patient with those that don't have a science background. Bazz seems to be still substantively correct. He is correct about it leaking through the tank walls due to the size of the hydrogen atom- which influences the size of the hydrogen molecule- sounds correct about the means of production of hydrogen- correct about hydrogen in confined spaces.

Historically I've been a fan of hydrogen- but I suspect he is correct about it being less efficient than the coal/ electricity/ battery/ electric motor cycle. Efficiency isn't everything though- maintenance, cost, fleet compatibility is also important.

Hydrogen burns fairly clean though in the vehicle and using electrolysis can be produced cleanly using renewables.

Large scale electricity and transport energy is a big problem.

Perhaps some cheap small generators can be developed for home renewable installations that use hydrogen as a storage mechanism. If it works at small scale then it can be scaled up.

Overall I think Bazz did a fairly good job of a complex subject.

Toni,

Even at "only" -253C this is technically a difficult problem to solve, as the hydrogen will slowly have to leak off as it warms, and cars made to use hydrogen presently cost more than $100 000 to build and still suffer from the problem of driving with a bomb in the back.
