Thanks for many kind and helpful comments. Yes, hydrogen is an energy store (vector or carrier) not a fuel. If it is made sustainably, e. g., via water electrolysis using renewable electricity, the hydrogen energy cycle is very low carbon. The storage problem needs to be resolved though, hence our work. And sorry for looking like an alien blob in the video. I really must lay off the Mars bars.
Her notes SOLID?? made me smile like an idiot. The feeling of having exciting and unexpected findings truly is marvelous.
That last few sentences said by Tim Mays.. really nicely put: "Knowledge and understanding about how the world works is absolutely vital in order to be able to predict, to be able to design, and to be able to work better with materials and energy. I don't know whether we'll change the world, but I hope we'll make a contribution to a more sustainable world"
OMG MOFs!! I never thought you'd cover them in a video, they are pretty advanced stuff! I got to study them in undergraduate university and even got a paper published in the AIChE journal. It is nice to see them on your channel Brady, thank you!
love this video. i wish our politicians understood how important science is
It's great to see all these (mostly) positive comments about our work. The results showed in here are finding their way onto a publication, so more news on this very soon. Cheers!
Apparently much excitement over potential materials capable of absorbing Hydrogen as an alternative means of storage. Palladium; (amu 106.4) has been known to exhibit this property since 1866. It seems we're in a race now to isolate what material is better suited at STP.
Very cool! This is somewhat close to my field of work (solid state chemistry, albeit not hydrogen storage), so I found this extra interesting. Have to check the paper out when it's published.
This is great news indeed! All the luck to the team.
Did they rename the ISIS facility?
This is so cool! It's so cool you make these videos Brady -- I love hearing about this stuff! Also, you have an awesome job. :D
What would be interesting is backing up to the big picture. Battery storage of electricity is much more efficient than hydrogen electrolysis/fuel cell to get back to electricity. Pumped water or pressurized gas are more efficient. Why waste time on hydrogen? You can't mine it - it's not a "fuel source" - it's just a way to store energy. Molten salts look like they're better. Ultra-capacitors? Flywheels? Theoretical limits of each of them?
We expect those big oil insiders in government won't legalize your hydrogen storage methods.
MOFs for adsorption and storage of hydrogen have been studied for quite some time...
There is such a thing as a limiting factor. Just because there is more carbon dioxide to be used, doesn't mean it is used up quicker. The other reactants in photosynthesis have not changed, so the uptake of carbon dioxide will be limited by the availability of the other reactants.
@0:33 Hydrogen is not an energy source. It is a method of storing energy. You need to produce it first maybe via green sources like wind or solar.
Like the "WOW" from the SETI data
Another breakthrough of sience! Thankyou for sharing Brady!
Great report Brady! This is potentially incredibly exciting! I hope you make subsequent videos if there are any developments on this!
Adsorption of hydrogen will (probably) always require low temperatures or high pressures simply because hydrogen is such a light molecule. We might find a wonder material that works as room temperature and pressure but I wouldn't bank on it. Liquid nitrogen temperatures aren't trivial to maintain in a car type situation but they are within the realms of possibility.
The problem I can see with that is even if that were true, CO2 doesn't just stay fixed in Carbon Compounds in plants forever. The CO2 is recycled back out again during decomposition/after it's eaten/by it's own cellular respiration. So while plants may try to sponge up some amount of CO2, at the same time CO2 output is also increased. There may be some small buffering effect by simply having more biomass, but that's limited.
Wow, that's a potentially very exciting result!
Brady sure does love zooming in for no reason 5:58
This is fantastic! I can't wait to see where this technology goes. :)
The ISIS facility!?
Awesome! And I thought I was clever when I made a lego cup holder.
i thought hydrogen was not energy dense, though it will do me just fine, and what an exciting nascent technology here! awesome vid, and very hopeful.
I haven't been to NewScientist since it was free, until yesterday, ironically on an unrelated link. It's an odd choice in references, especially as ScienceDaily remains freely available. Both sites primarily republish press releases, and if you doubt those press releases, the referring information is often at the bottom of the article, in case you're unsuccessful doing search based on the names, institute and field at arxiv, pubphys or pubsci.
This has the potential to be a disruptive technology, if early research is indicative of what is possible, and is not yet using close to optimal materials. Meaning more optimal materials could be found with more research. 70-80K is still a bit low for economic mass production, but it looks promising.
You use solar energy to split water molecules, you get oxygen and hydrogen, you burn/oxidate the hydrogen, get energy and water... tada!
Im assuming the comment below meant to say all the fossil fuel available in the world. But what he doesn't realise is that anything that burns is effectively a fuel, what determines what we burn and keep is based on importance, value and cost effectiveness. Readily available fuel is becoming scarcer by the second and in return the cost of finding more, drilling and getting it to the consumer is becoming ridiculously expensive, further more price of fuel effects everything from the cost of an...
Extremely efficient, relatively high temperature hydrogen storage...
Is it as efficient with deuterium as well? Because then it could be given to people working on fusion rockets for extremely efficient fusion fuel storage.
Also, has any of this been given to NASA yet?
... and besides, that doesn't change anything on the fact that the hydrogen acts as energy storage in that process, not as energy source.
"so the uptake of carbon dioxide will be limited by the availability of the other reactants."
It is not. It is the other way. The limiting factor was the lack of CO2. Plants were (sort of ) starving.
This is huge!
If a group of hydrogen molecules demand a certain amount of space between each other, nobody is explaining how or why a foreign object between them suddenly nullifies their need for space. If that molecule needs distance from one molecule, it will need distance from any other. Are we talking about molecules or atoms?
OMG WAT a Kiwi on one of Brady's channels! There's hope for me yet lol
I don't think it's renewable per se , only that if you were to electrolyse sea water for example as a source of hydrogen, the supply would be virtually limitless.
The more important aspect is carbon's impact on the environment. The planet can't handle another 50 years of us burning carbon at the current rate, let alone 500.
I love learnin stuff I didn't even know I didn't know.
Egg to the cost of bringing fresh water to remote villages In the third world. Anyway.... This is extremely exciting stuff and I can't wait to see further developments.
Great, I hope they get it into nature or nature chemistry
thank you, in behalf of the world
Are we getting a video of Mr. Phd. James Clewitt soon?
Amazing stuff!
This is good science but you can store Hydrogen as water then electrochemically split it to Oxygen and Hydrogen If you dont want to burn the Oxygen with the Hydrogen you can just dump it out with the exhaust It is safer then storing it in its pure form If for some reason it catches on fire and explodes only a very small amount will burn and the rest is stored as water You might ask how do you keep the water from freezing If you use Potassium Hydroxide as the electrolyte it will freeze at -33 C
Speaking of green technology, I wonder how Seamus Garvey's compressed air storage wind energy project is going.
great video!
interesting stuff.
Given his experience with videos... I'd guess that is the best he could do...
sorry to past again are you going to send out a link to the Journal article once published love to read it
while there are hydrocarbons out there, I don't think we:
1: want to put more carbon than there ever was or could have been in the Earth's atmosphere (while I'm sceptical about AGW, I'm quite sure that putting more carbon will cause global warming never seen before)
2: can get them to Earth economically (as in cheaper than making hydrocarbons with solar energy using syngas)
3: we will run out of hydrocarbons in at most 70 years, if you're around 20 you're bound to see it happen
But it takes more energy to split the strong molecular bonds than you get from the recombination, so you would be better off using that energy to drive the vehicle then to split the water. You would be wasting energy for no good reason when it would be more efficient to just run direct from electric.
Hell, the only real reason we use liquid fuel in cars now is because in terms of storage mass, the fuel has better energy density than electrolytic cells and is faster to refill.
Efficiency is key.
thank you
220 kelvin to go until it's practical.

There are many more examples. In some greenhouses where it is economically possible, farmers inject extra CO2 to promote plant growing.
Yes, of course. That unfortunately only works until you actually start doing the math. Assuming every day is perfectly sunny and you cover your whole roof and backyard with solar cells, you still don't get enough hydrogen to travel to work and back.
Question: how is hydrogen a renewable energy source? Surely hydrogen is just a way of storing energy.
You are ruining my dreams of having a fuel cell car with a colossal brick of palladium as a hydrogen storage medium.
i dont think you can store h2 in small size container
its just an idea ........... but keep try to but it between two materail plate
may be in 2327 you can do it ,,,, I hope
What about the filling time of the MOF's if i remember from my dis (last year tbf) are long
You need a car with a bigger fuel tank or one that's more efficient. Our perfectly ordinary diesel car will do about 600 miles on a tank.
Apart from crops growing much faster due to increased CO2 in atmosphere, there is no problem with CO2. CO2is increasing, temperature stopped increasing about 15 years ago.
Where will this journal be published?
Fossil fuels, as today, will last more than 500 years. Peak oil is a fallacy.
I don't know where you're getting your information from. That's simply not the case.
Some plants respond poorly to excessive amounts of CO2, some respond well.
CO2 absorbs and radiates infrared light and warms our atmosphere. Fact.
If you look at the instrumental temperature record of the past three yrs in the northern hemisphere, You'll find that each was the hottest year in recorded history. You'll also find that roughly 80% of the record breaking highs have been within the past five yrs.
Valeska, is that a New Zealand accent I hear :)))
Naw, you don't. It broke when the cup contained coffee. Sidenote: Coffee with sugar + Lego = not a very fun way to spend fifteen minutes.
Storing hydrogen in an efficient way could also allow the building of spaceplanes, couldn't it?
I know this may sound mean but.. that bald guy is a Sontaran, isn't he?
try grafeen
Hi Brady! :D
Someone fix her glasses
Interesting inorganic chem project but I am not happy, hydrogen is too reactive, too risky. If you can decrease risk by combining with a substrate (like the TNT story) then great, but otherwise I am not convinced, images of the Hindenburg come to mind. Nice chinese girl tho ;)
Hi
you need molecular hydrogen to burn it (both the combustion engine and fuel cells burn the hydrogen), water doesn't burn
while water is a way of storing hydrogen, the video is about storing energy using hydrogen, water is useless for that
If petroleum is becoming so scarce why is the US capping all our wells across the country and refusing the Canadian pipeline system? Only privet owners are pumping and Canada is exporting. My one word for petroleum is WHY?! I'm not putting down this video in any way. I wish like everything I had a home base Hydrogen producer and storage system.
Look at the back in forth before your comment: actual points, no insults, explicit references.
Now your comment starts off with an insult and specifies nothing. Which ever point you think I'm wrong about, you would likely find a lecture from UCTV, University House or the old Research Channel which can cover the point in detail. Or perhaps you think that's some sort of popularization for idiots, in which case, try arxiv.
Ignoring your Neanderthal like comment about the presenter I'd like to point out that hydrogen is no more reactive than the petrol in your car. In fact if you'd filled the Hindenburg with vaporized petrol you'd probably get a far larger explosion. This type of hydrogen storage should be significantly safer than petrol, unlike petrol if you spill this material while it's on fire will won't flow around creating a huge burning puddle.
Tim Mays is very interesting to listen to but a bit sore on the eyes, in fact I got physically ill by the close up shots of him. If you could refrain from using the close up shots when filming him I'd appreciate it. Otherwise very exiting stuff and please keep the making these videos. :)
and how much energy are you wasting to compress this hydrogen into these materials ? i thought the goal was to replace an energy source not deplete one to make the other ??? to be practical you need something that uses less energy than it is creating.
750 Bar Oo
But how is the Hydrogen removed from the pores?
I'd love to have a car that runs on cat litter :3
It sure is a great scientific achievement but I would really appreciate if they stopped kidding us about hydrogen being a renewable energy source. Sorry but no. Hydrogen does not grow in pressure bottles. To get hydrogen, you need to produce it by spending more energy than you can ever get back from it once it is produced. And that energy has to come from somewhere.
naaa dont believe these ppl brady its fine the way it is.
You should not label Hydrogen an energy source. It's a way to store energy. You can't 'just get it' from the water, you need to put in energy to break the bond. I hate it when otherwise good videos start with such flaws.
There's nothing to believe here. It's my opinion.
And it looks like 12 other people share it with me.
Please film from a further away next time. It's IMO not really comfortable to watch the video when the guy is speaking.
Back off Brady! Is science, not orthodontist's advert!
Why can't we just put electrolysis machines into cars and store water as fuel?
Asian women who speak with a british accent are scary.
This makes me so excited, maybe this will crack the fuel cell electric car problem. I read up a little on MOF's. What metal in the substrate is the best so far?
Please keep us updated.
So i wonder if the hydrogen has a metallic appearance when in this form. Also curious if it has super conductor properties. I don't think this has been directly observed, only predicted, and only circumstantially backed up so far.
While this indeed is an excellent discovery, unfortunately enough, hydrogen production either requires more energy than can be retrieved from the gas as a fuel (e.g. produced using electrolysis), or when create by reforming of hydrocarbons produces the same by-products (CO and CO2) as burning of fossil fuels. So to make it practical as a "green" fuel, the main breakthrough needs to come in the technology for producing it at an industrial scale.
thx - glad you liked it!
Typically you just warm the material (probably in this case it would be enough to stop actively cooling it) and the hydrogen or other adsorbed (note this is different to absorbed) gas will re-enter the vapour phase. The process is fully reversible so the fuel tank should last the lifetime of the car.
Both of your comments in this particular thread, are wrong. Please cite your source.
I'd certainly not like a container with that kind of pressure to blow up in my car.
it's exciting stuff
Thanks for that. I remain open-minded about this technology, but still not convinced about the risks. Let the Americans try it for a few years first I think. She is a bit of a babe tho isn't she, she could light my fire anytime, esp if the opening sequence is anything to go by ;)
