Hydrogen Vehicles

Fairly comprehensive review of hydrogen as a fuel.
Points she seems unaware of:
1. Handling hydrogen was done routinely from the 1850's up until the mid-1950's in the form of Town Gas or coal gas. Super pressures are not some requirement.
2. There have been breakthroughs in fuel cell catalysts using base material and nanotech.
3. Nuclear is an ideal source to crack water for hydrogen because the hotter the water is the less power it takes to separate the hydrogen from the oxygen.
4. Yes, we have oceans of water and it does not require fresh water as an insurmountable hurdle.

Here's one....

It’s a solid energy source but handling, transport, and infrastructure will keep it from being anything significant for a long time.

Helium?
Or was it something like they usually filled it with Helium but they used Hydrogen for some reason?

The Hindenburg was hydrogen, which is dangerously flammable. The accident caused airships to move to helium.

Town gas was the main source of lighting and a major source of heating and cooking in the Northeast from the mid 1800's until the mid-1950's. It was about half hydrogen and half carbon monoxide.
The Northeast didn't stop using it until the natural gas pipe lines came up from the South in the 1950's.
My loft in NYC still had the old 3/8" gas pipes. They were black iron, but were damn near impossible to cut with a big saber saw or break with a heavy hammer.
correction 3/8ths ".

Interestingly, a lot of those onboard survived.

A lot of airships were already helium. At the time the US produced the majority of the world's helium and we wouldn't give any to Germany.

What's your IQ buddy??

Ran across these recently. Blimp aircraft carriers using helium. They were both lost in storms.

You get that’s a far lower demand application and cars don’t have pipes connecting them to a grid, right?
And Storing pressurized hydrogen will always be a safety issue.

There are various methods some of which don't involve major pressure.
A gallon on ethanol contains more hydrogen than a gallon of liquid hydrogen. Read that in a scientific conference, but that requires cracking/reforming the source. Ideally, the source would be something like hydrazine in water which cracks easily and contains no carbon (which can kill some types of fuel cells).

Advanced Solid State and Liquid Materials
The Office of Energy Efficiency and Renewable Energy and the Office of Fossil Energy are working to develop innovative materials for reversible hydrogen storage including high surface area adsorbents, metal organic frameworks, and metal hydrides, as well as approaches that are regenerable off-board such as chemical hydrides and liquid carriers.

you aware that hydrazine is a particularly toxic substance
Posted on 2/12/24 at 12:02 am to Auburn1968
Now you are talking about adding hydrazine to cars, with no idea of how much WORSE that is than pressurized hydrogen.
