Welcome to the News community!
Rules:
1. Be civil
Attack the argument, not the person. No racism/sexism/bigotry. Good faith argumentation only. 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. Do not respond to rule-breaking content; report it and move on.
2. All posts should contain a source (url) that is as reliable and unbiased as possible and must only contain one link.
Obvious biased sources will be removed at the mods’ discretion. Supporting links can be added in comments or posted separately but not to the post body. Sources may be checked for reliability using Wikipedia, MBFC, AdFontes, GroundNews, etc.
3. No bots, spam or self-promotion.
Only approved bots, which follow the guidelines for bots set by the instance, are allowed.
4. Post titles should be the same as the article used as source. Clickbait titles may be removed.
Posts which titles don’t match the source may be removed. If the site changed their headline, we may ask you to update the post title. Clickbait titles use hyperbolic language and do not accurately describe the article content. When necessary, post titles may be edited, clearly marked with [brackets], but may never be used to editorialize or comment on the content.
5. Only recent news is allowed.
Posts must be news from the most recent 30 days.
6. All posts must be news articles.
No opinion pieces, Listicles, editorials, videos, blogs, press releases, or celebrity gossip will be allowed. All posts will be judged on a case-by-case basis. Mods may use discretion to pre-approve videos or press releases from highly credible sources that provide unique, newsworthy content not available or possible in another format.
7. No duplicate posts.
If an article has already been posted, it will be removed. Different articles reporting on the same subject are permitted. If the post that matches your post is very old, we refer you to rule 5.
8. Misinformation is prohibited.
Misinformation / propaganda is strictly prohibited. Any comment or post containing or linking to misinformation will be removed. If you feel that your post has been removed in error, credible sources must be provided.
9. No link shorteners or news aggregators.
All posts must link to original article sources. You may include archival links in the post description. News aggregators such as Yahoo, Google, Hacker News, etc. should be avoided in favor of the original source link. Newswire services such as AP, Reuters, or AFP, are frequently republished and may be shared from other credible sources.
10. Don't copy entire article in your post body
For copyright reasons, you are not allowed to copy an entire article into your post body. This is an instance wide rule, that is strictly enforced in this community.

I've always gotten nothing but weird vibes from proponents of hydrogen. Everyone I've ever spoken with is either sceptical and waiting for it to make sense, an unshakeable zealot, or a speculative investor who hates BEVs.
It has a place in heavy industry. But right now green hydrogen is very scarce and expensive. Until that changes, it will be somewhat boutique.
99% of the world's hydrogen comes from natural gas steam reforming. That's why the vibes are so weird, it's a fossil fuel industry distraction
It can never work, the energy needed to make it is more then energy available from the H. It's like needing 1 barrel of oil to make 3/4 of a barrel of oil.
I'd say this is the least problematic aspect of all. If it was a viable energy storage solution, then it'd work even with higher energy input.
If that energy came from renewables then it could have some uses (wherever nothing but hydrogen will do), but yeah.
The case with transit is such that they keep trying to invent ways not to use trains, and we just have to tap our feet and wait for them to look facts in the face.
I guess you never been to the Alberta tar sands, that's exactly what they do with gas and water to make oil.
It takes huge energy to produce, store and transport. Just use that energy directly. Calling hydrogen stupid was the only smart thing Elon Musk has ever said.
I'm glad the ICE hydrogen engines have been coming out. Not because they're directly useful. Outside of an engineering challenge (which is perfectly fine), they have no purpose outside of some racing applications.
I like them because it flags people who obviously have no idea what they're talking about. They like ICEs for what it is. And I do actually get that; from an engineering perspective, there's a lot of fascinating things going on inside there. However, efficiency was already hydrogen's biggest weakness. Fuel cells are 40-60% efficient, and is only one part of the hydrogen chain. You're going to replace that part of a chain with something that has traditionally struggled to get 25% efficiency? Why? You're doubling down on hydrogen's biggest weakness. This is the opposite of min-maxing.
So anyway, if they bring that up as anything other than engineering and racing purposes, they're a moron.
Yeah I've seen those, and agree. It's cool that you can do that stuff, but it's not gonna happen. Just use BEV already and build more trains.
I'm a proponent of Hydrogen if for no other reason than I find it foolish for the transportation industry to place all of it's eggs in one basket.
