====================================================================
Researchers at Kyoto University's Institute for Cell-Material Sciences (iCeMS) have developed a new approach to speed up hydrogen atoms moving through a crystal lattice structure at lower temperatures. They reported their findings in the journal Science Advances.
"Improving hydrogen transport in solids could lead to more sustainable sources of energy," says Hiroshi Kageyama of iCeMS who led the study.
Negatively charged hydrogen 'anions' can move very quickly through a solid 'hydride' material, which consists of hydrogen atoms attached to other chemical elements. This system is a promising contender for clean energy, but the fast transport only happens at really high temperatures, above 450°C. Kageyama and his team have figured out how to make hydrogen anions travel even faster through a hydride at much lower temperatures.
"In the past, it was believed that the key to high ionic conductivity at low temperature was to stabilize a material's high temperature phase by introducing chemical disorder," says Kageyama. Scientists do this by adding oxygen-containing compounds called oxides into the structure. Instead, Kageyama and his colleagues introduced an ordered structure into a barium hydride crystal, which caused hydrogen anions to move significantly faster even at 200°C.
"Achieving high ionic conductivity at low temperatures by ordering the anions is unprecedented and may be applicable to various ionic conductors in the future," says Kageyama.
Kageyama and his team changed the structure of a typical barium hydride by introducing layers on either side that are composed of hydrogen attached to another anion. By doing this, they made three different materials, using bromide, chloride or iodide anions. This provided a more ordered structure to the original material, preventing it from changing from the highly stable and symmetrical hexagon-shaped lattice usually found at high temperatures, to a less stable orthorhombic-shaped structure as it cooled. Hydrogen anions moved through the organized lattice very quickly at 200°C. The material even conducted the hydrogen anions at room temperature, albeit at a slower rate.
"Improving hydrogen anion conductivity down to room temperatures could enable low-temperature operation of electrochemical devices, like fuel cells, and open up avenues for their use as industrial catalysts or as solid hydrogen sources for hydrogenation reactions," Kageyama says.

Hydrogen Pingy......................
Everybody knows that /sarc
“a new approach to speed up hydrogen atoms moving through ...”
Sounds like a hydrogen pipe. I’d think hydrogen storage would be the thing sought after.
this is not needed
electric cars are here
“this is not needed
electric cars are here”
Yeah but think of the research money!
“ this is not needed. electric cars are here.”
************
Electric were here about 1912 too. Weren’t practical then and aren’t practical now….
So this stuff is not quite a room temperature superconductor. But it is trying to be.
“Electric were here about 1912 too. Weren’t practical then and aren’t practical now….”
Weren’t these the same “experts” that gave US the Kyoto Protocol of yesteryear?
If I’m not mistaken, Nicolai Tesla proved it’s viability in a ‘34 Pierce Arrow and had them scratching their heads on that one.
Problem was, as in most cases, the greed of men couldn’t control and profit handsomely from the technology.
Why..... because the energy source was freely available to all that had the knowledge to tap into it.
Same goes for hydrogen powered technology as it’s been proven viable many times by many different inventors throughout the years only to be snuffed out by whatever means necessary.
It is inconceivable that no one within the last one hundred years as well as in our supposedly modern “advanced society” hasn’t figured out how to efficiently separate hydrogen from a water molecule and adapt it as a closed loop system on an ICE.
Until such time as society values people instead of money and control, we’ll keep going around that mountain.

Agree; I’m a proponent of hydrogen powered vehicles as well. Full disclosure; I actually own a small amount of Nikola stock. Company got off to a rough start for sure. But, I didn’t risk the family farm so no worries if it turns to dirt. But, nevertheless, I think hydrogen power has an image problem. Whenever hydrogen is brought up folks have visions of the Hindenburg tragedy. But, I think the breakthrough will first come with big heavy duty truck, long haul eighteen wheelers and such. Pure EV’s just aren’t and never will be practical for this sector. Anyway, we shall see….
You mean like...facts?
Unless you have "free energy" to make it (like solar) it take more energy to make it than it releases when you burn it.
You can't store it, it leaks through the walls of the container.
It is inconceivable that no one within the last one hundred years as well as in our supposedly modern “advanced society” hasn’t figured out how to efficiently separate hydrogen from a water molecule and adapt it as a closed loop system on an ICE.
Yeah, they haven't perfected perpetual motion, nor have they figured out how to turn lead into gold either.
Now methane, on the other hand....what's wrong with that?
But the giant electric generating plants aren't.
Do your research, if it’s even possible anymore as scrubbing the interweb seems to be a thing nowadayz.
Free energy is all around US as Tesla undoubtedly proved so storage of aether is totally unnecessary.
Hydrogen, on the other hand, is a different matter altogether as all one needs to store is pure H2O. Efficiently separate the hydrogen, ICE burns it, exhaust recombines into H2O, hence a closed loop system.
Perpetual motion or alchemy has nothing to do with this discussion.
Methane..... nah, I’m more of a propane proponent though I can recognize methane emissions when they’re around.
Yep..... the Hindenburg is always the go to. Funny how that works. Azzclown media can’t promote the things that will benefit mankind as a whole as it’s pretty much the constant drumbeat of fear porn.
Neat thing about Hydrogen when it does set off, is the flame travel is pretty much straight up since it is the lightest element.
Breakthrough will only come when enough people have decided to throw off the “chains of bondage” and come together for the benefit of the whole. Don’t see that happening anytime soon as money, power, and control are the order of the day.
We have the strength in numbers but not the will nor fortitude to work together.
Research!
I made hydrogen back in the 60s. I've assembled automotive hydrogen cells. Splitting water into O2 and H2 is a very slow process. What would take you overnight to produce, would be used up by the engine in a few seconds. Plus, like I said, it takes more energy to make than you can get out of it.
Free energy is all around US
Right, there's lightning, wind, sunshine, cars run great on that....oh wait....no they don't.
as Tesla undoubtedly proved so storage of aether is totally unnecessary.
Right, and where are all the working models of these "free energy" contraptions?
all one needs to store is pure H2O
You can't make H2 out of pure water.
exhaust recombines into H2O, hence a closed loop system. Perpetual motion or alchemy has nothing to do with this discussion.
Of course it does. Do you think you're the first one to spew all this crazy talk?
Methane..... nah, I’m more of a propane proponent.
Methane has more hydrogen in it. Propane (C3H8) needs to be refined....but Methane (CH4...AKA natural gas) comes right out of the ground, with no refining required. They burn it at the oil-well head and refinery just to get rid of it. It's a lot easier to get power out of NG than water....you just burn it....Plus you can make other hydrocarbons from it, like alcohol, gasoline, synthetic oil.
though I can recognize methane emissions when they’re around
Both methane and propane are oderless.
