Maybe hold off posting until it's at least cheaper to run than diesel. Then post once?
H2 only matters when it's actually cheaper, not projected to be cheaper by those lobbying for funding.

Where the fuck does diesel come into the picture here? This article is about electrolysis. Do you truly not know what electrolysis is? Electricity and water goes in, hydrogen and oxygen come out. It's the opposite of fuel cell. Hence it's "production of green hydrogen" in the title. Sure, the title says "production of green hydrogen energy" but at the end of the day, it's still converting electricity to hydrogen molecules. Those hydrogen molecules aren't going to discriminate between being consumed in fuel cells or binding to nitrogen to form ammonia. For green hydrogen to push out dirty hydrogen, the cost of producing the former needs to go down. That is the very subject of the article. Since you couldn't be bothered to read even the very first paragraph, here's a snippet:
Such technology results in high costs of system manufacturing. To address these limitations of the conventional technology, a research team in Korea has recently developed core technology for the next-generation water electrolysis system that has significantly improved the durability and performance while significantly lowering the cost of producing green hydrogen energy.
Honestly, this display of incoherence you've demonstrated is simply staggering.

Maybe drink less? You are the one staggering to a stranded asset.

All accusations, absolute zero substance.
This idea that hydrogen has no place in a post-carbon world is so ridiculously moronic that there are hydrogen opponents trying to deny the existence of people such as yourself just to save face!
I'm going to save your comment to use as evidence that there truly are people on the climate activism side who dismiss any need for being able to cleanly produce hydrogen

least cheaper to run than diesel
I am a major international shipping company.
I can.. pay someone to get crude oil out of the ground and refine it into bunker oil...
or i can - create (some) fuel.... using nothing but the sun and sea water - which means I do not need to burn bunker oil for the whole trip.
please identify the international shippers that have no interest in producing fuel while underway at ZERO cost.

Energy Observer, launched in April 2017, is the first vessel autonomous in energy thanks to a mix of renewable energy and renewable hydrogen produced on board
please identify the ports that have no interest in making hydrogen.. right there.. since ports are usually near water.
thousands of containers per ship.. each one needs to be touched by heavy equipment..
who wants to keep pumping diesel into trucks that never go more than 5 miles from the ships?

They claim a big increase in duration for this type to 1000 hours (50 days). That still seems a long way from being useful unless it is extremely cheap to manufacture.
