- Опубліковано 13 чер 2024
- The world is in the middle of the biggest economic transition since the Industrial Revolution. The hegemony of fossil fuels is being challenged as the price of renewables comes down.
But there is still a long way to go. Global greenhouse gas emissions must be halved by 2030 to have any hope of reaching net-zero by 2050.
From a solar testing station run by the Qatar Environment and Energy Institute, earthrise travels to Orkney in the UK where scientists are developing one of clean energy’s holy grails - green hydrogen.
In Norway, we visit a carbon-neutral data centre cooled by hydropower. And we speak to Christiana Figueres, the co-founder of Global Optimism and former UN climate chief.
With reports by Cassie Farrell in the UK and Inspire Films in Norway, this programme explores the green society that could be ours.

Thanks for visiting us at Green Mountain!
Thank you for having earthrise there! It's great to see projects like yours in action and making a difference.
I have little idea. Why not storing this excess energy in efuel. Meaning we take hydrogen and combine it with carbon to get efuel. Why we do that because it's more efficient no need to compress or cool the efuel. Just suggestion. Mina from egypt . Wish you the best
Al Jazeera knocks it out the park once more! Brilliant video:)
Thanks again!
Just asking for your opinion on a different concept of my own that is quite basic. The build can at least be of 2 ultra strong permanent magnets, one above another where the top magnet stays stationary on a plastic* container filled with water while the other is inside that container. Between the top magnet and the container needs to be a very narrow gap for which a light sheet of lead* can easily slide between the magnets just enough to cause the bottom magnet to fall as if it were a delicate power switch that the rise and fall will help* generate more electrical power than it would take to move the lead* sheet in and out of that gap in least frictionless way, maybe levitated by other magnets. The water is basic to prevent damaging and even far to much noise.
.
In summary... it would be as if the permanent magnets can be switch on and off like electro-magnets.
.
I tend to come up with a whole lot of various ideas that worked out awesomely, but... not always able to test some of my ideas out.
Hydrogen is ok. Costs a lot of energy and water to produce, store, transport and consume. Basically a less efficient natural gas in terms of energy and cost but greener.
I like how nobody talks about the round trip efficiency of hydrolysis based H2 gas..... hint: Less efficient than charging a NMC or LFP battery.
when the world have good people with brilliant minds, the world move forward.
So true Rami, but it's such a rarity!
Fantastic Video. Wonderful Video. Beautiful Video providing enlightenment & Knowledge to All. God Bless Earthrise. May God Bless All my Brothers & Sisters who are behind this wonderful initiative. Wonderful video. All should watch & appreciate. God Bless the Nature. God Bless whole World. May God Bless All. Most Wonderful Program. I would like to join this initiative. May God Bless All. Thank You.
RE Scandinavian Data Centers... if done smarter they could heat water for Salmonid Aquaculture or other species and that would be smart
God Bless this Program Earthrise fir enlightening us with such wonderful knowledge. Thank You.
So glad you like it Joy. Thank you so much
Well done
Great video!!!!
We have to transition away from fossil fuels to clean energy like solar, wind, and nuclear.
"Energy, like time, flows from past to future".
Please update Earthrise Playlist
Good. Now let's only hope we're not already too late to save ourselves.
Oil and gas-producing countries try to undermine the process of transitioning to green energy.
That's nonsense.
The potential of Hydrogen as a fuel and power source is fascinating. I find it puzzling as to why it doesn't get anywhere near as much attention as battery power does especially given that at 7.05 the project manager explains how hydrogen is being used to extend the range of the electric vehicle and as this documentary also shows, hydrogen can power ships and even planes. It will be very interesting to come back to the Orkney islands in 10 years!
It would indeed. Let's hope that the world will have taken up solutions like green hydrogen more widely by then.
Hydrogen has very low well to wheel efficiency
Isn't the whole point of hydrogen that it creates electricity? Why then not use batteries and store more
Because of the economic crisis and the rate of unemployment now is the best time to invest and make money 💯
Exactly sir
Investing in crypto currency is one of the best chance of making money
Crypto is the future
Buy gold and crypto
I wanted to trade crypto but got confused by the fluctuations in price
Solutions are already there, they just need to go global to make a difference
so no chance then as all politicians i can see are going inward and nationalist
Hydrogen leaks no matter the material used as its container as it is the simplest element and therefor the smallest. Any other solid element's atom size would be like a size of a basketball while hydrogen atom would be the size of a marble so there would be gaps between the basketballs for the marbles to fall thru. And if the leak ignites from, say, static electricity the flames would be invisible, so you wouldn't know if its on flames.
Its a bejesus i invented because is is both horizontal hoover dams in winds or tides x 1000 and vertical more versital with airfoil to create suction and keep directional naturaly with 100 % bocking and releasing doulble the betza limits upside down and sideways and reverce equally equal and opposite reactions flipping flat blades sideways against it own halfs edges simontanisly bejesus is powerful beyond measure. Amen
Notice just a hand out scam by oil and nuclear no reply speaks clear and sneaky trademark is always bogus they ate there lunch in triple meltdowns 30 1/2 lifes diet still other hand in president pocket stuck no other way out lots of shovels text ignore k i will bury le6ad caskets remnants send 13 and mylar gold thick sheets just to be safe and the drones .charged up this time please
Well done. Very informative. Thank you!
It's more efficient to store electricity in a battery and use it to drive a motor.
Matlosana must start to grapple with these issues since mining is now a dead industry. Where does one start?
If you are looking for a way to help the environment you can use ecosia they are a search engine that plants trees
I think, for the US anyway, geothermal can give more capability in the near term than hydrogen etc.
🙏🙏🙏...would love to work with this org..
I have little idea. Why not storing this excess energy in efuel. Meaning we take hydrogen and combine it with carbon to get efuel. Why we do that because it's more efficient no need to compress or cool the efuel. Just suggestion. Mina from egypt . Wish you the best
Why combine with carbon, when the goal is to reduce carbon emission.
@@samad4895 this carbon come from co2 capture . It's called efuel. It does not produce excess co2 rather it recycled it.
@@minamikhaeil9314 it sounds cool but its not logical, the idea behind carbon capture is to take the carbon out of atmosphere. Carbon + hydrogen =CH4, burning of it will oxidize it to produce CO2. The entire process will even be a waste of energy
@@samad4895 we still need to calculate which process in energy efficient. Because to store hydrogen alone u need to compress and cool it which take a lot of energy then to reproduce electricity from hydrogen it's 25 less energy efficient. Meanwhile efuel could be more efficient. Keep in mind we can capture co2 from burning the efuel to recycle it which could save energy rather than capture co2 from atmosphere. I have a lot of ideas but can't find institute to foster. Mina from egypt
Overall life cycle emissions of electronics is widely varied.
Even Google search query consuming ~0.3w energy is kind of a guess. It depends on how old of a process ICs are used for server, networking and client device. How optimized hardware and software is for any given task. Weather or not waste heat is reused or forced in to environment with even more energy.
Same with artificial light these days. High efficiency LEDs can deliver ~200 lm per watt. Which is a fraction incandescent bulb consomption (~13lm per watt) at similar brightness.
Power consumption per MB of data is lower on a Gigabit Ethernet than on Fast Ethernet. Thanks to EEE faster connection can sleep for longer :)
14:58 The airline industry only serves the rich. The internet serves a lot of people, thus, computing has smaller carbon footprint per person than tourism!
You may be right, but travel brings much more joy than stupid selfies of billions of people stored in " the cloud" for what? To fulfill their vanity
So we can use this data center heat to heat our houses.
So firstly good video Thankyou for your great work. I do believe green hydrogen will have a part in the future of our renewable world especially in planes , large boats and maybe long haul trucking , I disagree with it being used for energy storage or small vehicles.
The main problem is that the base level physics for producing green hydrogen means that you get 20% of the electricity that you put in out . This is unavoidable.
Meanwhile grid scale battery storage is cheap to implement, converts electricity at a very high 90% ratios on efficiency, which means compared to hydrogen you get 4-5 times more out of your stored electricity. And the technology is here now and can get us to our goals in time .
Same to be said for electric cars , instead of hydrogen where electricity cars can easily have 300 + miles now and most of the charging is done overnight at your home , the only time you need to charge quickly is if you do a long road trip in which you generally want or stop every few hours anyway .
So in conclusion I would say green hydrogen has a big part to play in our future but we should be using the currently rapidly expanding technology we already have that works very well , as we research and develop newer technologies to complement them too. But waiting 15 years to have large scale usable hydrogen technologies is too late . We need to be rapidly transitioning now with what we have.
No.
@ would like to add any context to your comment ? Reasons why my view is wrong ? I would enjoy a discussion
@owen bradshaw Great comment, I completely agree hydrogen has a big part to play but when it comes to smaller vehicles like cars, battery power is more practical. That being said, battery power has still some pretty big challenges, especially when it comes to disposal and waste. I think hydrogen could have a bigger role to play especially if electrolysis of water can be made more economical. While I also agree we can't wait for the transition, it would be great to come back to Orkney in 10-15 years and see the progress of these technologies.
@@industrealised2326 you should look at redwood materials , they say they can recycle 95-98 % of the materials from a lithium ion battery and I’ve heard of others claiming similar numbers , redwood materials are scaling currently , I think by the time large numbers of evs come to their end of life it is likely that most of the batteries can be recycled as long as the manufactures are proactive . Yes it will be interesting to see how they’re going
@@owenbradshaw9302 I'll definitely be sure to check them out, thanks for the heads up!
👍🏿👍🏿👍🏿
But there is larger problem of transportation and storage with hydrogen.. And if you calculate the efficiency until it reach your vehicle it is only 33% which is much less than electric vehicle and more over it is not economical
It still makes sense on long distance heavy transport. Like ships due to energy density BEVs would be less efficient due to additional weight.
Europe and Asia could benefit from a unified, electrified railway system to transport goods more efficiently :)
If we were willing to unifi railway It could take ~50 years just to retire old equipment and consolidate it into a smaller and smaller area. So we don't create unnecessary emissions. To increase capacity we could use double decker trains. For efficiency we could automate train network, drive slower when capacity allows and when electricity is more expensive. Containers that see a lot of miles could be changed to fiberglass instead due better aerodynamics and reduced weight.
We should order in advance from bulk so we would need less packaging and less containers with flexible delivery :)
Uncanny resemblance to Aphex Twin
OK so green hydrogen... 2 massive issues... 1. Fossil Fuels are the main source of hydrogen so far... 2. hydrogen leaks like a sieve through nearly everything... containment is a big issue...
The rich and politically powerful don't want this to happen. All they are concerned with is to keep the status quo, control, and power.
4:23 one argument hydrogen haters bring up is hydrogen needs to be transported. if plenty renewables are available, hydrogen can be generated in the refueling station, at home, or within the car!
Generating hydrogen from water has low EROEI. Energy Returned On Energy Invested. Also mankind is experiencing a shortage of fresh water. It would be better to develop hydrogen from seawater.
I want as much fun in my life as the girl was having in the data center.
Only 50 years to late !
SRM, desalination, tree planting (they trap water in the soil), carbon dioxide removal, and buoyant shades over glaciers.
Google iter
👍 Now we could use a plan for the island of trash piling up in the ocean. Ideas?
You guys are drinking your own kool aid
Hydrogen car seems cost effective in comparison to electric car for developing countries! Government should pay closer attention to this!
Tidal energy is fully predictable. There are 4 slack waters a day. 2 at high tide and 2 at low tide. So the tide is moving about 20 hours a day.
Tidal energy is Lunar. Most other energy sources are Solar.
to much bullshit the was a guy the did it like around the 90s have a car the work was going to put it in the market and them he got kill like wtf
Just more marketing hiding truth
ZERO DIVERSITY THUMBS DOWN
100 years from now we'll have no water.
Welcome to the great reset 😡
Fuel Cell without a battery is not a solution. To produce H2 is very inefficient, beside the example of the island...
No.
Lol clearly they have no understand 🤣 and don't want to upset interest groups
