At that point it was using its first stage, which used kerosene. The other two stages were hydrogen fueled for better ISP.Nohing new about hydrogen powered flight...

Petrol - liquid at normal temperatures and pressures. Will run out of a ruptured tank and pool on the ground, inside a vehicle, etc. Highly combustible vapour which is heavier than air.
Hydrogen - a much lighter than air gas at NTP. Will not run out of a ruptured tank and pool on the ground, inside a vehicle, etc. Will not remain around as a highly combustible vapour. Will dissipate from a ruptured tank extremely quickly.
one of the reasons is that the highly inflammable doped fabric envelope of the Hindenberg caught fire, and for a long time people thought it was a hydrogen fire.
But the US Congress is doing its best to ensure that global stockpiles of helium are being frittered away so there will soon be none left.

I vote for T Stoff & C Stoff. Can you imagine Karen or Kevin filling up with hydrogen at the local station? At least topping up with T&C will see off the weak & feeble pretty quickly.
Seriously folks, lektricity is the way it's going for personal transportation. They will not promote a system that will require an entirely new & VERY expensive infrasture.
The serious green types, the ones devoid of propaganda & false emotion, are predicting that boosting the electricity generation & distribution to feed all those batteries is the way to go. Maybe they been planning it for years already . . . .
What you should be worrying about, is those same folk are predicting that only 40% of todays number of privately owned vehicles is sustainable. That's 60% of your precious motor cars that will be taxed off the roads . . . .!

I think there's no way we're going to be near the proposed CO2 reductions promised. Own it.
Cameron proposed 8 new Nukes in 2010.
But we're closing most of them down.
If only.....
We're currently importing power from the EU, at about 2 NP stations rate.
Fusion may be viable, but it's "30 years away". It has always been 30 years away... Buy tungsten shares.
An interesting suggestion I saw was to use ye olde NiFe cells for storage. They aren't efficient in terms of size, but they're much lower tech and polluting than fancier lithium alternatives.

They probably use too much nickel, which is relatively expensive.
These days Lithium Iron Phosphate, or LiPo, is the cheap and cheerful flavour of the day. No expensive cobalt or nickel.
At work we are currently building hydrogen injection systems for large diesel engines.
It improves fuel economy by 10-15% upto 70% reduction in particulates, and 25% reduction in carbon monoxide.
Essentially it's just a mini boiler which uses electricity to make hydrogen from water and then has fancy ecu to carry out the injection.
Shipping companies are interested but it's tough to make the m put there money on the table.
LiPo is quite big in the radio controlled industry, only downside is that LiPo is quite volatile

Another more recent theory involves the airship's outer covering. The silvery cloth covering contained material including cellulose nitrate which is highly flammable. This theory is controversial and has been rejected by other researchers because the outer skin burns too slowly to account for the rapid flame propagation and gaps in the fire correspond with internal gas cell divisions, which would not be visible if the fire had spread across the skin first. Hydrogen fires had previously destroyed many other airships.
And https://en.wikipedia.org/wiki/Hindenburg_disaster#Incendiary_paint_hypothesis
I believe it's widely mined, for example Australia is the largest producer of ore and Chilie has the largest reserves, but it is shipped elsewhere often China, for refining.

Because our nationalised generating industry owns lots of nuclear power stations?
Any country that wants to build its own nuclear weapons starts by building nuclear power stations
apart from a client state that is supplied by another friendly nuclear power
The populace is fed the false story that it is so they will benefit from unlimited cheap non-polluting energy.

While conducting research in Germany, Bain unearthed documents that support the coating theory. A 1937 letter from the Zeppelin company to the paint manufacturer expressed concerns, noting that tests showed the covering was “readily ignited by an electrostatic discharge.” Also testing in Germany in 1938 by the Wireless Telegraph and Atmospheric Electrical Experimental Station found the cause was “the poor conductivity of the aluminum paint coating on the outer skin.”
“Hydrogen did play a role. There is no question about that,” said Bain, whose conclusions have evolved over the years. “Once the fire started and the outer cover started burning, hydrogen played a role.”
Bain doesn’t want to call his findings a theory. Instead, he said, “what I did is connect the dots of a lot of events.”
