Most biomass is, well , Free, and if engineered and handled correctly hydrogen can be produced from steam in a process called Gasification and be burned safely in a ICE engine..
Check out a website called ALL POWER LABS
And believe it or not, they have used hydrogen peroxide as rocket fuel, the 90% hydrogen peroxide.
100% hydrogen peroxide is very unstable.
H2Gen in Alexandria had a pallet-sized Hydrogen Generation Module (sold to Air Liquide in 2009) to produce hydrogen on site from natural gas - Just drop the pallet with a forklift, hook up a gas line and electricity. Other reformers can be made to convert other common fuels into hydrogen for fuel cells (gasoline, diesel, ethanol, propane). It could allow for rapid and scalable roll out of fueling capacity.
This process emits some pollution, but the net for natural gas conversion is supposedly about half the total emissions of burning the equivalent of gasoline, so it is still an air quality improvement for urban environments.
You can also deliver hydrogen from trucks to storage tanks, to really clean up the air in geographically disadvantaged places like Los Angeles or Mexico City.
I don’t know the hard economics of what is lowest cost, the relative performance advantages, or the importance of the safety issues; but the logistics of standing up a fueling infrastructure for hydrogen is quite feasible.
The prices is about $47k. Pretty steep, but the price point will come down. It’s starting to look more affordable and practical. Minutes to fill beats hours. My guess is the price of the fuel will be ridiculously high.
Thanks, sounds interesting; I’ll check it out.

But isn’t it bad if it disperses quickly? It means that more H is in proximity to O2 if and when it ignites.
The grain silo problem.
Whereas a liquid is not completely atomized. Actually gasoline has to be atomized before it will ignite properly - a carb or fuel injector.
Starting with the enviros of course.
Hydrogen is not a fuel. It is an energy storage medium. It costs energy-- which is money-- to separate hydrogen from water or other compounds. Only part of that energy is regained when hydrogen is burned in a heat engine or used in a fuel cell. Because of entropy, you will NEVER get it all back.
The hydrogen economy is a foolish dream, fueled by government power instead of common sense, using money that the government siphons off the economy in a massive-scale Ponzi scheme.
It is sad that such is being promoted here on Free Republic.
That would be equivalent to a perpetual motion machine, and is a violation of the laws of thermodynamics.
No, it is not. It requires energy to make pure hydrogen, and you can never get that same energy back. At best, hydrogen is an energy storage medium. Mostly, it's another government "green energy"scam that burns money.
Show me a source of H2 that you can get without pouring energy into separating it from another compound, or leaving Earth.
You can't.
It's not a fuel, it's an energy storage medium.
Yes we’ve all done the Brown’s gas experiment.
I don’t dislike hydrogen....but it’s production requires energy, And the materials used in a Brown’s gas experiment requires energy to produce the materials needed in such quantity and purity to achieve a yield high enough to produce usable quantities of hydrogen
Right on. This engineer agrees.
In a accident in a vehical once that tank or container is cracked open you would be amazed in how fast hydrogen disapates, literally in seconds.
Unlike gasoline, or LNG that stays around and ignites.
They have actually done tests on vehicles that might still be on your tube to see what happens in a accident between different fuels, if you , or some call hydrogen a fuel.
I also saw a video of a hydrogen welder of a commercial where they sell these hydrogen welders.
They say that welding with hydrogen does some strange thjngs.
You know the burning bush that Moses saw and the flame didn’t consume the bush ? That flame could have been hydrogen.
In a car accident gasoline gets splashed all over the place, no wonder they use it in naplam.
LNG tends to seek the lowest point like water.
So which one would you want if there was a car accident ?
I’d pick hydrogen.... Be gone in seconds.
No, it is a fuel, as well as an energy storage medium, just like a hydrocarbon. You need an oxidizer to liberate the energy.
FYI, the whole rocket community refers to it as a fuel.
Flammable paints, a supposed leaking fuel cell , lighting from a thunder storm and 1930s technology sounds like the perfect storm to me.
Furthermore, I never said that you could extract hydrogen without using energy.
The rocket industry refers to it as a fuel because, by and large, the rocket industry is government-funded. I used to be in it.
