I probably should have said "fuel cell cars are EVs." But yes, you can make an ICE powered by hydrogen. It is likely to be a niche product, mainly sports cars and perhaps some diesel engine replacements.

The cost will drop to nearly zero, just like the rest of renewable energy production. Tanks are cheaper, smaller and lighter than li-ion batteries. Fuel cell cars are also EVs, just like BEVs. The "efficiency problem" is greatly e

Literally everyone has a massive incentive to make green hydrogen work. It is pretty fundamental to industry, manufacturing, agriculture, transportation, etc. There is no path to zero emissions without it. In reality, just a handful of voca

You will need many millions of them, and enough generating capacity to power then all. That is many years away. Likely decades. There's also no technological issue preventing the expansion of hydrogen stations. It's also worth not

I suspect that the Dead Internet Theory guarantees the death of non-curated social media. Basically, any online community that doesn't do human verification of its users will simply be overrun by bots. In other words, social media plat

> lithium ion energy density has ~tripled in the past decade. That's actually false. It originated from a literally made-up story by Bloomberg. In reality, NCA cells have existed since the late-2000s. Effective energy density was 25

That's a completely ignorant statement. Hydrogen cars actually exist and work exactly as advertised. There are no fundamental challenges. This reads like one of those anti-BEV posts from a decade ago. In both cases, the author is total

> There is no corresponding infrastructure delay for EVs which are already being adopted. That's an utter fantasy. We are nowhere near having enough infrastructure to do this.

It can be true for specific websites. And while it won't fool dedicated users, it can be good enough to convince casual users and poorly informed investors.

It didn't. It only forced many of its more important users off of Reddit. It is likely on the same path as Digg before it.

It demonstrates that efficiency is primarily about making the car lighter and more aerodynamic. Something that is lost in our world of giant SUVs. And no, making battery powered SUVs doesn't solve this problem.

They're literally charged in their garages. This is the same idea. Seriously, what is your point here? Once you are a few miles away from home, you are closer to a public refueling station than your home. If there is a ubiquitous publi

Hydrogen is a fundamentally superior technology to batteries. It is Tesla that will eventually have to move on to fuel cell cars, not Toyota doing the other way around.

No. Fuel cells can be constructed with no special materials. Even those that need them need extremely small quantities of it. A PEM fuel cell needs about as much platinum as a catalytic converter.

Then you can use whatever technology that hasn't be driven into obsolescence yet, but basic physics nearly guarantees that outcome. Maybe flash memory versus HDDs, or perhaps fiber optics over copper wires. BEVs where at basically zero

1) That's a lie by BEV companies. I keep on telling people that fuel cell cars are EVs . So where does argument even come from? It comes from nothing. There is no basis to make this claim. Not to mention that the point of renewable en

by _hypx 3y ago
The problem with that thinking is that BEVs are guaranteed to be more expensive in the long run. A hydrogen car is basically an EV minus the most expensive part. That is going to be a decisive advantage.

Hydrogen storage has a higher density than li-ion batteries.

And if someone said that vacuum tubes are the future, what is your response? It's pure absurdity to claim that an obsolete technology is the future. You'd immediately get up and ridicule the obvious non sequiturs in their logic. F

That's Luddite bullshit. Complete gibberish. The simple fact is that fuel cell cars are also EVs . As a result, there are no fundamental limitations compared to BEVs. They are fundamentally guaranteed to be just as good as BEVs. And s

Hydrogen is a fundamental superior technology compared to batteries. If anything, Toyota is decades ahead of Tesla. Everything Tesla is aiming to do is just a pale imitation of what Toyota is already achieving.

There is no "elon factor." This is pure hype.

This is delusional. Hydrogen is a fundamentally superior technology compared to BEVs. Tesla is the facing the next big crisis when the limitations of battery reveal itself. Batteries are simply not a sustainable technology. It is Tesla that

Tesla fanboys need to stop being so short-sighted. All innovation in cars will not stop at the BEV. There will be a next technology leap beyond the BEV. And if you think honestly about what that is, it will be hydrogen cars. Simply because

It's a guarantee that hydrogen production will take off, and in the long-run disrupt basically everything else. All of the critics are trapped in the mentality that green hydrogen will always be expensive. They are totally oblivious to

The real answer is neither: Switch to mass transit as much as possible, and build nuclear reactors instead of natural gas plants. This would very quickly drop CO2 emissions even further and not involve any new technologies nor huge new supp

Switching to 12,000 miles per year and 32 MPG (exactly, not ~30, the MPG system exaggerates differences for small numbers), you get 375 gallons or 3.3 tons per year. That is the driving number I used to get 1.2 tons per year for the Tesla (

> An average US car emits about 4.6 tons of CO2-e per year. So, a Teslas extra manufacturing emissions are offset in 0.5 to 3.5 years. The average is 2 years, which is in line with Tesla's claims. That's comparing an SUV/p
