Every country in the world should be able to produce Hydrogen.
Well done Australia 👏👏👏.. Brazil started the production of Green H2 too, we have basically 90% of the country eletrical energy from renewables.
Together we can build a cleaner world, a better world 🖖 🇦🇺🇧🇷
Saudi Arabia is starting too!

Please do not be fooled by hydrogen. Do your calculation. Solar and wind is 8x cheaper thanHydrogen.. What a muppet.
Looks great in a 2 min animation ad for SA energy & mining, but there are many obstacles & issues associated with hydrogen production, storage & transport not mentioned here.
Hydrogen is great in that it does not pollute when burnt, but it takes a lot of energy to produce, embrittles metals & if there was an accident involving hydrogen it would make a very big bang.
Hydrogen has a place in certain industries, but for transport it has far too many energy losses & potential for disasters, stick to deisel for transport for now at least.
Green hydrogen production , hydrogen is the lightest and most abundant chemical element in the universe (H2) it is found in the sun, stars, in water molecules, plants and animals here on earth. It tends to stick as well, in South Australia we have abundant sun & wind that we turn into green energy. They produce more green energy than we consume, we can utilize the excess green energy to produce Green Hydrogen. Weee..

Good
This works great in your high school chemistry lab, but doesn't scale up and is still dangerous, hydrogen is hydrogen no matter how you make it.
Shipping hydrogen is STUPID.
It can be made everywhere.
Jika kita bisa memanfaatkan kelebihan energi listrik dari kendaraan dan tersedianya alat elektrolisis kecil, kita bisa memproduksinya juga walaupun sedikit,
Producing hydrogen using solar and wind or some kinda seaweed research is one thing. Lowering the temp to negative takes a lot of energy.
❤❤❤
We all need better ways to store excess electricity that is generated from solar and wind. And hydrogen does have promise. But this youtube video skips over the real issues on the subject IMHO. Hydrogen production, storage and distribution is fraught with a multiple of so far unsolved issues. For brevity, let me examine just its use as a fuel in a car. The storage tank required in a car needs an extreme form of engineering. Consider the gas bottle on your BBQ. The "LNG" gas in this cylinder is a liquid at a few bars of pressure (1 bar is equivalent to 1 atmosphere). Hydrogen is virtually impossible to liquify at normal temperatures. The most promising prototype hydrogen fuel cars use 3 separate tanks containing hydrogen gas at crazy 720 atmospheres pressure. (The recent deepsea diving sub trying to submerge to the Titanic wreck tragically imploded at about 200 or a bit more atmospheres). Just image one of these hydrogen-powered cars on the highway which has a head-on collision with a truck. Awful for such things to happen but such collisions are not rare. At 720 atmospheres, the explosion will be gigantic. I will not choose to live anywhere near a hydrogen refuelling plants. Not even hundreds of metres away.
Yes there are buses and cars and truck that run on hydrogen. None though are ready for general release. They are prototypes, some of which have been tried on and off for years.
---That's just one problem. There are more. I am hopeful for eventual solutions, rather than more feel-good videos.
Agreed, 700 bars travelling on the roads sounds pretty dangerous. Perhaps for now using H2 as a fuel for power plants that rely on green energy e.g. when there's no wind or at night. I'm not sure how efficient that is considering that electricity is needed to produce H2.
Imagine a hydrogen car parked in your garage. The tanks connecting valve is leaking. Hydrogen fulls the roof space in your garage. You enter the garage from the house side door and press the door opener which creates arching of the brushed motor which is surrounded with hydrogen. Then kaboom no more family and no more house, and possibly no more neighbours houses.
The Norway refuelling station is another example of how dangerous hydrogen is.
What are the storage costs? Keeping it refrigerated will not be cheap.
You ask what the costs are, and then says it's not cheap after. @@WeighedWilson
sorry, to put things in perspective, a 40 ton truck hurtling down the road in the opposite lane with whoever behind the wheel and who knows what kind of maintenance issues is FAR more dangerous than a 70kpa hydrogen fuel tank. hydrogen will win in the end because you can transport and refuel quickly just like gas, it's inevitable, hydrogen will be the default vehicle fuel
If you are consuming water which is vital source for life then it is a bad hydrogen not a good hydrogen.... What about collecting all alcohol in the world and produce hydrogen plus water and at same time reduce alcohol consumption... Good for everyone and everything 😊
Cool YELLOWSTONE make HYDROGEN. 😊
I hear there is a significant amount of carbon and methaine gas produced as a byproduct of running these not to rain on the parade we all would like a cleaner energy i just feel like i havent heard of any such green energy each option has a caviat to it but im sure well get it down adventually
Ok, now when would the CO2 be produced in this exactly?
little late to the party but this method produces only water a byproduct. However, it is still more expensive than separating hydrogen from natural gas like methane. The second method will produce carbon dioxide and carbon monoxide as a byproduct but it is unfortunately how 96% of all synthetically-prepared hydrogen is made. If solar production gets adopted widely, those numbers can be changed and we can one day have true green hydrogen!
I am always getting suspicious when only the positive is mentioned. Highly likely that there is more on the negative side that they want to hide
The oxygen?
I think he/she meant by how Hydrogen is inflammable and the process,of transporting it is risky.
It also eats up space thus needing excessive metal usage to preserve it. It's like extra cost than basic fuel. I'm not sure if it's a valid point tho
It is best to put containers on electric trains over 1,000 kms
There is always wasted grid energy overnight.
Turn that overnight stream into cash,as well.
Easy money.

Using the excess energy to replace the Hydrogen used in fertilizer production is a very positive plan. Using Hydrogen for transportation makes no sense the very low power to volume and losses during compression and transportation make it a waste of energy when a battery can be charged directly with almost zero cost to transport.
Stop calling everything "green" 😂
😊
It can't be everything "
*Yellow* 😅. Green is correct.
Hydrogen is the real future no need to dig all of the rare earth under the world to make a huge battery
Before watching video : What do you mean.
After watching video : Just stop saying the word "green"
Bro, thinks the world is not green💀
So you’re creating Hydrogen to trade which will result in more infrastructure and ship transportation to do so? 😂
How to ship it by whatsapp?
@@renelionel5449 what?
Hydrogen from electrolysis?! I think it is not that simple.
1 First of all, I think we need sterilized water for >90%.
2 I think we have to keep the water temp
We don't have enough coal to produce it!
have you wtached the video dude ?? it uses green energy not coal
@@namelless9791 do the math!
@namelless9791 how are we going to build the thousands of wind turbines required with the hundreds of tons of coal required just to make the rebar required in each foundation? Where will we get hundreds of tons of carbon fiber fore each one?
Will... will. Will... will not
Sir any kind of hydrogen is very volatile and explosive. Please don't push this products to people who don't know how to handle explosive items like hydrogen.
Do not comment on a topic you are not sure of.
Hydrogen is volatile but so is gasoline and it has been around for years
Hydrogen will quickly disperse when it is exposed to the atmosphere leaving little room for explosion
Hydrogen? What a waste
Green Hydrogen. Now that is an oxymoron!
There is energy in the atmosphere and air we breath, we just need to figure out how to extract it. That green hydrogen thing is not sustainable and very costly.
Says who?
Nice cartoon. Shame about the reality.
Very funny, hydrogen uses very expensive electricity, to generate hydrogen, there is an energy loss in the process, when the hydrogen is burned in a power station, there is an energy loss, so this process is very expensive way of producing less energy than you started with. then there is the little stated fact that hydrogen needs to be stored in a compressed or liquid state to be able to get anywhere close to the energy density of petroleum which is hydrogen and carbon mixed together. or coal. again very high energy density, this means easy to store.
Hydrogen on the other hand is not easy to store, hydrogen being the smallest element actually leaks out of its containers through the material, this causes hydrogen embrittlement, those ultra high pressure storage tanks, tend to explode, hydrogen goes boom really well.
Lets stop playing with seabreezes and sunbeams. The Sun controls the earths climate, its is the only source of energy that produces enough energy to heat the earth. Turn off the sun and it will get to absolute zero very quickly.
We rely on the sun for Everything. The sun is a thermonuclear fission reaction. DO YOU GET IT? We survive by relying on NUCLEAR energy. Nuclear energy is Cheaper and safer than Green hydrogen.
THORIUM MOLTEN SALT REACTORS are easy to work with, easy and economic to build and transport, no nuclear waste from each fuel cycle and TMSR's can consume other Nuclear waste. they produce vast amounts of cheap power, unsightly wind farms will not be needed, our birds don't have to die by blade strike. exotic mineral solar panels won't be needed. all of this green pollution can be removed.
Excellent response to this green hydrogen rubbish. Who the hell puts up this green hydrogen crap.
The sun is nuclear fusion, not fission.
TMSR’s do still have toxic waste products but they do use most (95%) of their fuel compared to other fission reactors which use only a small portion of their fuel rods & the sun is a fusion reaction, not fission.
