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.

The problem with FCEVs right now is cost.
First of all, we already have good electric distribution infrastructure, but don't have an industrially-sized hydrogen distribution infrastructure. It's way easier to install a new charging site than a new hydrogen refueling site. Building hydrogen out will be expensive, unless you're talking about vehicles with a centralized depot, like busses or ferries.
Second, fuel cells aren't really that efficient right now, and neither is electrolysis. Due to losses at each step, 100 miles worth of green hydrogen is way, way more expensive than 100 miles worth of electricity.
With more research, that could change. But for now, there's a reason you don't see many FCEVs.
The same story was said about wind, solar, even BEVs too. They all had to be expensive before they hit mass production.
But the advantage of FCEVs is that they have very low resource requirements. The cost floor is much below that of BEVs. Eventually, they will be as cheap as ICE cars or less, and the fuel will be cheaper than gasoline.
The efficiency argument is hugely exaggerated and is mostly coming from BEV companies. Even if you believe it, you should be aware that photovoltaics are terribly inefficient. But it doesn't matter because solar is made from sand and sunlight is everywhere. Hydrogen has the same idea going for it. Made from water and renewable energy, it too will be extremely cheap.
