You're completely ignoring the fact that it takes 3 to 5 times as much energy to actually drive a hydrogen car, because of the (in)efficiencies of the hydrogen production, supply and consumption chains.

And given that the driving of a car is what consumes the most energy in its lifetime, the much higher efficiency of a BEV 'pays off' the higher production costs, both monetarily and ecologically.

That's just bullshit from BEV companies. At best, it's something like 2x. At worse, it will take less energy, because you have waste energy from renewables. Wind and solar farms have a tendency to produce energy all-at-once, and shut down all-at-once too. You need massive amounts of energy storage to solve this. And the cheapest way of doing this is with hydrogen.

So as a result, you just get a lot of super-cheap hydrogen that otherwise can't be used. BEV don't solve this problem at all, leading to a lot of wasted energy.

Finally, fuel cells are also electrochemical systems, just like batteries. The notion that batteries will always be more efficient is just another lie from the BEV companies. In the long-run, this will be a unanimous win from fuel cells, because they will be equally efficient while also been much cheaper.

No, that is physics.

You could stand to learn some of it.

Physics state that both are types of EVs. Both fuel cells and batteries are electrochemical systems. In fact, you can literally call a hydrogen fuel cell a hydrogen-air battery.

So whoever comes out and say "but muh physics" has no idea what he's talking about. If you really knew physics, you'd know that there's holding back FCEVs in physics.

- 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.
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.
