“The pipeline under the Mediterranean Sea will carry green hydrogen, made from water via electrolysis using renewable energy.”
this is a pipe dream ... electrolysis is a very inefficient way to make hydrogen, and anybody can do it ... heck i did it in high school chemistry class ... so why is a pipeline needed? ... just make your own hydrogen right on the spot anywhere there is abundant water and “renewable” electricity ...
AND hydrogen is EXTREMELY reactive and EXTREMELY difficult to prevent from leaking since atomic hydrogen is EXTREMELY tiny ...
EXTREME reactivity and EXTREME difficulty in preventing leaks is clearly a disaster in the making ... assuming these fools ever manage to build any part of their hydrogen pipeline, i predict numerous and massive explosions in the future ...
Would it not be better to transmit the electricity and make the hydrogen near its point of use?
Don’t ask me why they would want to make hydrogen from electricity in large quantity.
Natural gas is as “green” as it comes. Idiots.
Just put in some blimps. That’ll work.
Hydrogen?
How nice.
KA-BOOM!
*This* should end well. /s
Hydrogen is a bad idea. It requires a lot of energy to produce and involves the breakdown of water. The most precious commodity on the planet. Once the water is gone we are screwed.
We don't really know where water came from or how fast it is escaping into space, there hasn't really been a lot of study on the matter ( thank god or the politicians would have another yoke around our necks with that )
Let's see, 2 million metric tons, 64.7 (roughly) kWh per kg to produce and compress hydrogen, carry the one... Hmm, so 129 bn kWh.
Let's see... Spanish grid. 258.60 bn kWh total.
Net import of 7 bn kWh/yr currently.
So literally half of all power in Spain as it exists today for this project. And somehow the renewables (of which wind is the largest at 27 bn kWh) will power this thing entirely.
That's going to be some hella expensive energy when Germany gets done building that much infrastructure within Spain JUST for the stuff that is supposed to go into the pipeline.
One month ago, we had the first ever energy positive test for nuclear fusion.
From memory, 2 mega-joules of laser input energy created 3 mega-joules of fusion output energy.
One problem...
From memory, it took 2,000 mega-joules of conventional energy to fire up dozens of lasers and deliver just 2 mega-joules into the fusion target!
Hydrogen is an energy storage media. It does not provide net energy. Electrolysis requires huge amounts of electricity to split water in those quantities. Where is the electricity for electrolysis coming from?
Greenies are so gullible.
Call me a genius. What if you bound hydrogen to carbon atoms and transported it that way? Solves all the density and reactivity problems. No cryo needed.
Ummm - natural gas is as “green” as it gets - I bet they wouldn’t be doing this if we hadn’t sabotaged the Russian pipelines...
I thought the Krauts learned all about hydrogen back there in zeppelin days.
The pipeline under the Mediterranean Sea will carry green hydrogen, made from water via electrolysis using renewable energy.

Nope. Not buying it. If Italy can produce hydrogen using “renewable energy” then the countries on the other end of the pipeline can too. This pipeline has another purpose.
Hmmm.......wondering how much energy (electrical?) is used/needed to make green hydrogen?
Anyone know?
Just like the new Knives Out movie. Interesting
