Green hydrogen production

South Australia is committed to building a world-first hydrogen power plant near Whyalla in the Upper Spencer Gulf by 2025 fuelled by green hydrogen. Understand how green hydrogen is produced and the benefits to the environment, industry and the economy.

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 🖖 🇦🇺🇧🇷

Every country in the world should be able to produce Hydrogen.

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..

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.

Producing hydrogen using solar and wind or some kinda seaweed research is one thing. Lowering the temp to negative takes a lot of energy.

Jika kita bisa memanfaatkan kelebihan energi listrik dari kendaraan dan tersedianya alat elektrolisis kecil, kita bisa memproduksinya juga walaupun sedikit,

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.

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.

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

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 😊

[speedyparker]

Your using solar to get electricity and windmill, why convert it to hydrogen less efficient.

[armageddonready]

Shipping hydrogen is STUPID.
It can be made everywhere.

[nbsrbyy]

There is always wasted grid energy overnight.

Turn that overnight stream into cash, as well.

Easy money.

[edwardbarnett]

It is best to put containers on electric trains over 1, 000 kms

[DownToEarthMind]

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

[MrCarhoo]

Literally free energy. Not green however.

[jjamespacbell]

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.

[giffy]

So you’re creating Hydrogen to trade which will result in more infrastructure and ship transportation to do so? 😂

[yupyup]

Stop calling everything "green" 😂

[terenceiutzi]

We don't have enough coal to produce it!
