We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.
** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**
Rule 2- Your post subject cannot be illegal or NSFW material.
Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding non-TIL posts.
Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.
Rule 7- You can't harass or disturb other members.
If you vocally harass or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
For further explanation, clarification and feedback about this rule, you may follow this link.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.

Harvesting tiny bubbles from vast areas of ocean ground in wavy cold waters is not what looks very attractive or sustainable to me.
Also: Fuck green hydrogen, at least at bigger amounts. Hydrogen is a beast to store and to transport and should only be used for local use in some industries (steel, chemical) and maybe for short term energy storage when renewables are overproducing. Maybe. Never seen an economically sustainable project because batteries are superior in that area. Fuck green hydrogen.
Wait..was i wrong? I thought hydrogen was one of the better alternatives to head and oil. Yeah batteries are nice, but the weight is still a problem right? especially in like planes, giant ships etc
More weight less range more batteries more weight etc Energy density of hydrogen is up there, and especially if the safe storage thing ever gets solved, i was sure that would be a given
I seem to remember the only ' waste' it produces when combusted is water. Granted i would not trust to use it in a car... But a ship miles away from any danger of collision m? Also if it's 'free' bubbling from the ocean ground, what's the downside? giant cargo ships are ideal for hydrogen, no?
im imagining have one big floating platform, like those oil rigs at sea, with some kind of contraption with a pipe all the way to the bottom of the sea. Basically a gas station in the middle of the sea. Cheaper going m shipping
But your telling me it's not that easy?😭
Storing hydrogen is really hard, which results in heavy storage equipment. It's also very explosive.
When you weigh (literally) up the storage requirements for hydrogen versus electricity (batteries), electricity wins, especially as it can be generated any which way you like.
Handling hydrogen within the bounds of a powerplant is feasible, not in end usage scenarios like vehicles.
What @grue@lemmy.world says: Hydrogen is a scam by the fossile fuel bros. They need combustion engines to sell their products. That's the complete reasoning, that's all there is. And also be aware: Hydrogen is not feasible without bigger subsidiaries paid for by the common men directly into the pockets of billionaires.
Technical and financial aspect: Storage and transport of hydrogen kill the feasibility. End of story.
Hydrogen is a scam: they use the promise of 'eventual' hydrogen made from electrolysis of sustainable energy as an excuse to implement hydrogen made from cracking natural gas now, which only really serves to divert funding that could've gone to actual green projects back to the fossil fuel industry.
