Denatured is what they add to it to be metho bought in the stores.
It is an additive that is usually stated to be around 3% of the content.
Ethanol is alcohol.
It is what you drink. But generally in lower percentages.
I lived close to a Manildra plant.
Its products are starch and ethanol. (alcohol)
There are great advantages with using hydrogen in controlled circumstances.
But it only takes a quick look at what happened to the Hindenburg to see potential problems.
It had low density hydrogen. It just needed to be lighter than the surrounding air.
To use hydrogen to fuel cars or trucks, it needs to be highly compressed to be able to be affectively useful.
LPG is bad enough. Hydrogen is multiple times worse in comparison.

Totally agree. Hydrogen is problematic. Doesn’t change the original point that using Hydrogen to create Carbon based synthetic fuel doesn’t reduce CO2 emissions. It replaces crude oil. Sure they can used captured CO2 (from generation etc) to combine with Hydrogen to make Methane or Methanol, but in the end it still becomes CO2 emission to the atmosphere. Yes, as a straight fuel Hydrogen is very dangerous, but so is using Plutonium and many countries use it for generation and propulsion. Both can go bang in a big way, but at least Hydrogen goes bang and it’s over, and doesn’t create a 10,000 year problem!

The bang that hydrogen gives though is a big one.
They had a few steam powered cars a long time ago.
They were a huge problem in the event of the inevitable crash.
Ive had to deal with a few LPG fires, and they tend to make your bumhole pucker and vibrate a bit.
Hydrogen at least when it went bang would destroy just about everything around it.

I've seen videos of a few LPG Bleves, quite scary.
Will be interesting to see what the future holds. All I'm certain of is that it won't be EV's using the current battery technology and charging off the grid. It needs a leap in technology in at least one area for it to herald a mass swap over to electric propulsion.

One litre of liquid LPG for instance, will create a 2700 litre explosion, roughly.
13 44 gallon drums as bombs roughly.
Ive seen 44 gallon drums explode.
Its pretty impressive.
