Deakin researchers have described a novel mechanochemical process that can store gases safely in powders, using very little energy, in a repeatable process..........
Australian scientists say they've made a "eureka moment" breakthrough in gas separation and storage that could radically reduce energy use in the petrochemical industry, while making hydrogen much easier and safer to store and transport in a powder.
Nanotechnology researchers, based at Deakin University's Institute for Frontier Materials, claim to have found a super-efficient way to mechanochemically trap and hold gases in powders, with potentially enormous and wide-ranging industrial implications.
Mechanochemistry is a relatively recently coined term, referring to chemical reactions that are triggered by mechanical forces as opposed to heat, light, or electric potential differences. In this case, the mechanical force is supplied by ball milling – a low-energy grinding process in which a cylinder containing steel balls is rotated such that the balls roll up the side, then drop back down again, crushing and rolling over the material inside.
The team has demonstrated that grinding certain amounts of certain powders with precise pressure levels of certain gases can trigger a mechanochemical reaction that absorbs the gas into the powder and stores it there, giving you what's essentially a solid-state storage medium that can hold the gases safely at room temperature until they're needed. The gases can be released as required, by heating the powder up to a certain point.

That was an information dense post! I did not know that cat crackers used hydrogen, and in such massive quantities. Thanks for that.
I would not snort that. Unless I was Hunter Biden?
“making hydrogen much easier and safer to store and transport in a powder”
Why do I foresee something (like excess humidity or the like) causing these powders to “leak” gas and cause a catastrophic detonation?

Because acetylene cannot be highly compressed due to explosion hazard. So it is stored in cylinders which are filled with a porous gypsum-like material and ..

“The oil industry uses hydrogen gas at thousands of psi to take the sulfur out of fuels and to hydrocrack long chains into shorter chains if hydrocarbons this is essential to creating the precise C6 to C9 chains, bent chains and ring hydrocarbons we refer to as gasoline. Without massive amounts of hydrogen measured in the millions of lbs per year oil.refineries cease to exist. They are just giant hydrocracking, hydro isomerization, and hydro desulfurization planrs. Oil refineries are the largest user of hydrogen gas in the planet. They need it by the tonne and currently all of that is high pressure gas that leaks through stainless steel and turns it brittle in short order. Refineries have fires and blow up fairly often due to hydrogen leaks. So if they came up with a way to move hydrogen from point A to point B without thousands of psi and release it at will at the point of need it is a substantial breakthrough the oil industry will be all over this like a virgin on prom night.”
Fine point is ... this is huge for refining. Now if we could get the EPA regs tossed as unconstitutional and return to sane gasoline formulas it could be just in the nick of time. Build a new generation of refineries in addition to keeping our existing older plants operational. No refining shortages. Drill Baby, drill !

Good idea, but even a maintained trail would have hazards for a balloon ... unfortunately.
I have long thought that a solid form of hydrogen might be a useful store of energy... it’s far outside my expertise though.
“Your question does not make the headline a lie.”
No it doesn’t. You are correct.
The fact that hydrogen is not being powdered is what makes the headline untrue.
The text is more clear, saying the process stores the gas in powder.
My question was about the yield or efficiency of the process unrelated to the inaccurate headline.
Dehydrated water.
“I will guess that one liter of this stuff will get you less than one liter of GAS”
I would think so.
Yes. It sounds cool and is from a chemical engineering standpoint. But how beneficial might it be.
You're behind the times; drum, feathers, a little dance - rain.
Well it definitely gives you gas.
The X-43 scramjet was powered by liquid hydrogen and achieved Mach 9.6.
Unfortunately the cost of liquid hydrogen is impractical.
LOL - been in plenty of rain storms, some absolutely ‘drenching’ despite rain gear. Maybe I could work out something that has a funnel (similar to a rain gauge) that would go into a water bottle that’s strapped to my pack!

I suppose there could prove to be some narrow specialty application where this technology could prove competitive but can't see it being anywhere near cost effective for large scale industrial processes. Completely impractical and no where near ready for prime time. The key thing I’m hung up on is the time factor. There’s no way that this process can be competitive when it takes several hours in a ball mill. I’m also wrestling with how to do this with hydrogen without blowing yourself up.
I've pretty much categorized New Atlas articles as junk science. Just enough accuracy to support a flash headline but stretches accuracy mighty thin in the details.
My opinions…
Oh that’s hilarious!! I’m sharing it with some friends - thanks!
