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.

Ping!...........
So it takes steel balls to make this stuff?
And some other stuff, but yeah.......
Nanoparticles have incredibly high surface-to-volume ratio.
I know a guy who makes nanoparticles with a few hundred to a few thousand atoms (or molecules) each out of all kinds of materials, by the tens of pounds.
When you open one of his shipping jars, it appears to be full of smoke. You don’t open one without PPE and under a fume hood.
Headline is a lie.
How much powder volume of powder with trapped hydrogen gas is needed for one liter of liquid hydrogen?
So the Hindenburg would be filled with hydrogen powder instead?
Just the gas tank........................
Columbians have been storing energy in powder form for many decades..........................
As a hiker/backpacker type, I’m waiting for powdered water ... something lighter than 8 lbs a gallon.
Similar gypsum to an acetyline tank?
Something to figure out if there are cost effective applications for powdered hydrogen.
Definitely not a food additive, but maybe it’s also possible to powder other gasses with this method.
They do not tell us the energy density of this storage system, or how much energy is lost when extracting the available hydrogen.
If you snort powdered hydrogen, does it make your nose run? Make you pee more?
Imagine mixing a bag of oxygen and hydrogen powder..... might be explosive.
What would you add to it?
That’s what is used to make nanoparticles.
So in theory this would solve the problem of storing and transporting hydrogen for vehicles and what not. Correct?
“As a hiker/backpacker type, I’m waiting for powdered water ... something lighter than 8 lbs a gallon.”
i think they already have that .. it’s called dehydrated water, and you simply add water to it to re-hydrate it ...
