Rules:
-
Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
-
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
-
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
-
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
-
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
-
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
-
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
-
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.
We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.
All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Can't speak for everyone but my criticism of hydrogen is not on its theoretical potential to displace fossil fuels as an energy carrier, but on its practical constraints today.
I don't see many people criticizing hydrogen like those who "attacked solar" but people more treating it like fusion - it's very likely the way of the future, but we shouldn't stand around waiting for that future to materialize when we can be making changes now that will help preserve our collective future.
Additionally, your theoretical ultra-efficient-platinum-free-corrosion-resistant-fuel-cell-and-electrolyzer future is competing against the theoretical super-energy-dense-durable-low-cost-solid-state-battery future, and I shook my Magic 8 ball asking which is more likely and all I got was "Ask again later" so... ¯\_(ツ)_/¯
The "practical constraints" are mostly just lies from competing industries. Case in point, a hydrogen tank is both volumetrically and gravimetrically denser than batteries. Loosely speaking, it is about 2000 Wh/kg and 1333 Wh/L. That's better than any li-ion battery.
It is plenty good enough to replace both BEVs and ICE cars. As long as it is zero emissions, it works.
Finally, FCEVs exist right now. Hypothetical magical batteries of the future don't. So this is a meaningless comparison.
My Master's Thesis and PhD Dissertation were focused on fuel cells as an energy storage system of the future - I've got more first hand experience than most with no influence "from competing industries". I want this technology to work - badly.
That said, you're right that fuel cell cars exist today, but so do batteries, and with today's technology any "meaningful comparison" will quickly point out that today's batteries are:
More efficient, cheaper to manufacturer, much cheaper to operate (have you checked the price per kg for (mostly fossil-produced) hydrogen recently? YIKES!), more user friendly for most (not all) drivers, and (a little more subjective) way more fun to drive.
Yes, batteries do have their problems (long haul & heavy duty applications, refueling time, cobalt sourcing, flammability, ...) But so do PEMFCs (fuel cost, platinum sourcing, reliability & safety of ultra high pressure fueling infrastructure, fuel cost, complete lack of availability for green hydrogen, fuel cost, relatively rapid chemical degradation of electolyzers through catalyst poisoning, forever chemicals involved in the production use and disposal of Teflon/Nafion, ...)
Again, I WANT fuel cells to win this contest, but today? They've got a lot of catching up to do before they overtake the leader, and unlike batteries, in their current state I could not in good conscience recommend purchasing an FCEV to anyone I care about.
I have two things to point out: I don't have to believe you on your claims of expertise. And the second is that I can easily accuse you of being decades out of date on your knowledge.
None of what you said is true anymore. FCEVs are a mature technology, and will cost very little to build. Green hydrogen is plunging in cost, and will be one of the cheapest energy sources out there. None of you claims about "catalyst poisoning" is true anymore.
So what you are doing is basically being one of those "experts" who attack a revolutionary new technology just as it is taking off. It mirrors solar skeptic just before solar power took off. All your doing is setting yourself up for total embarrassment.
I'm glad you finally understand. That being said, the quality of the content of the other guys comment, compared to your 30 comments, really should be an eye opener to you.
He's knows nothing. He's just name dropping debunked ideas.
Dude. We ALL know you don't know what the fuck you're talking about.
I've forgot more about this subject than you will ever know.
Look at yourself. If you're not sure how there's this thing called a mirror.
Dude, this is just funny ngl. I'm so curious how much you get paid
You're just like some of the others here: Stuck in 2015 and accusing everyone else of being paid by the oil companies.
Literally no one on the left support these kinds of fanatical anti-hydrogen positions anymore. Just this one Fascist is left. And just a bunch of conspiracy theories as the basis of reasoning. Not even a single coherent counterargument...
Says the person with no actual experience on the matter, unlike the person you are arguing with.
I am left, and I don't support hydrogen because it pales compared to the electrical solutions we have and will have in the future. So don't pretend your viewpoint is universal with the left, because it isn't far from it.
I also don't support Elmo in any way shape or form for your information.
Hydrogen would only be viable for airplanes, since they require higher density fuel at the lowest weight possible.
But other than that, hydrogen just isn't viable in the applications you name. Your EV information is also from 2015, so all your arguments are just projection. Plain and simple.
Not only are you wrong, it's you guys that are just repeating one debunked myth after another. There's nothing being said hear that I haven't heard already.
This is why you guys are stuck in 2015. It's just a bunch of obsolete drivel that originated from Tesla and other BEV companies.
If you are really politically left, then why not starting acting politically left? No one on the left opposes hydrogen anymore. This is quickly turning into an extreme political position. Possibly, a far-right position in the near-future.
If you don't support Elmo, then stop repeating his lies. It's like everyone here hasn't realized that Elmo has been lying for well over a decade. It didn't just begin with Twitter.
In the end, FCEVs are also EVs. They are also zero emissions cars. You cannot come up with a coherent reason to oppose them. It is the same style of argument as those that opposed wind, solar, even BEVs too. So there's only one reason conclusion, and that is to support FCEVs like any other green technology.
ROFL at your stuck in 2015 comment, I wish I were!
In 2015, hydrogen was ~$20/kg and trending down to ~$13-16/kg by 2017, with the DOE claiming it to be "about the same cost as gas today" despite the fact that 1 kg H2 is roughly 1 gge, so the costs were about 4x gas costs, and 4x their target of $4/kg at the pump.
Fast forward to today and guess what, ~~that price kept dropping, and it hit the DOE targets!~~
Just kidding - prices this year are up to $36/kg, making the Toyota Mirai one of the highest TCO cars on the market.
Take me back to 2015 when that hydrogen fuel was half the price!
That's a local supply issue. It reminds me of the polysilicon shortage of late-2000s. Plenty of people came out of the woodwork to proclaim the solar panel as a dead technology. But the physics of the idea, namely that it's all made from sand, meant that cost will eventually plunge and it did.
Hydrogen is the same story. Investment has recently skyrocketed across the world. No one except a few BEV fanatics are still opposed to hydrogen. That is why guys like you are stuck in the past. You are repeating the same story as what people said about wind, solar, even the BEV itself in its early days. It is guaranteed to be wrong.
