Yes, all of the above.

You have a big tank of fuel that can be stored up until you need it. It also takes a few minutes, not the hours you have to wait until a battery is full.

All close cycled cells have the same properties. Ultracaps are even better.

It wouldn't shock me if the Mirai has even bigger profit margins. Fuel cell systems aren't that much more expensive than internal combustion engines to build. If the Mirai really had those losses, Toyota would be literally losing

Yes it has happened or is nearly about to happen. FYI, the LR version of the Model 3 is $50k, about the same as the Mirai. By many metrics they've reached cost parity. Even if you angrily deny this, remember that EV are produced in lar

As we are talking about a large ticket item (cars), a 20% difference is a big deal. As with all fuels, this shouldn't be much more expensive than from a fueling station.

The point is that they talk about it. Either positively or negative, it means that they're using the public chargers.

In the Northeast, people often use fuel oil delivered to their house for heating. Except that this fuel oil is basically diesel/kerosene, meaning we already had a system of delivery fuel to people's houses. And yet there was never

Only because they have to. If there was a way to recharge within 3 minutes publically, the home charging solution would be rarely used.

Then I will have to disagree. I insist that it is still post-hoc rationalization. Sooner or later, hydrogen cars will be cheaper to own than a battery car. Once this happens, none of this reasoning will hold up to scrutiny. Should be noted

I think those people are simply living in the past. It is hydrogen disrupting batteries, not the other away around. In fact, I see a flattening of the pace of battery improvements, meaning the speed of this disruption event should be moving

It will likely be a transition from blended hydrogen before reaching 100% hydrogen later. Just because it won't happen all at once doesn't mean it hasn't already started.

Everyone says this but they still talk about public charging all the time. It's mostly just a rationalization.

by Hypx_ 5y ago
The difference is that for fuel cells, it has mostly already happened . It's quickly becoming a kind of denial where the haters simply pretend that it doesn't exist or insist on unsolved problems that have long been solved. It fr

You are already proven wrong. The biggest event in green energy is hydrogen right now. The only reason why people disagree at all is ignorance of recent events.

In this case it's mental distance. It's not be affected by the politics of other countries nearly as much as others. One big idea in Australia is the possibility of exporting hydrogen. It might be a factor on their thinking.

by Hypx_ 5y ago
Same thing. Everyone uses public stations all the time.
78.
by Hypx_ 5y ago
This is just post-hoc rationalization. The extra few minutes of refueling time is hardly a problem. Even so, eventually you likely will be able to refuel at home since home electrolysis is possible.

All vehicles are "negative." This doesn't make sense as a metric.

None of those alternatives have anything but a minor role. The overwhelming majority of grid energy storage will be from hydrogen energy storage: https://www.econstor.eu/bitstream/10419/236723/1/Ruhnau-an

The problem with this mentality is that is impossible to create a zero emissions grid with just batteries. You'll find that long-duration energy storage is necessary. Except this can only be solved via hydrogen energy storage. So even

Except no one drives at home. Every EV fan still complains about lack of public charging stations. I suspect few people really find home recharging as any kind of game changer.

Except you can extract 237 kJ/mole from hydrogen. A fuel cell is a battery and can approach the efficiency of a lithium-ion battery. > No, you cannot use existing gas pipelines for transporting hydrogen. You absolutely can. In fac

Really just a meme at this point. The risk here is that hydrogen cars end up being cheaper to run than electric cars. A real possibility due to the production of hydrogen from curtailed renewables, higher battery costs, hydrogen being much

Possible. In fact a company called LAVO is building a home hydrogen battery for energy storage. Although compressing it to 10,000 psi at home is not quite ready yet, although companies are working on it.

Solar panels cost money. It is not really nearly free. In the near future, you can make hydrogen with your own solar panels too.

As it stands now, the biggest revolution in energy right now is the rapid reduction in hydrogen cost: https://www.pv-magazine.com/2021/06/24/low-cost-renewable-hy... Once things hit their exponential growth c
