True, but it is not much different than gas stations selling CNG or LPG. It's doable since the land is there and you are still dealing with flammable chemicals. There is a lot of common expertise. Many hydrogen stations are in fact con

You'd be wrong. A hydrogen infrastructure would have the same footprint as gasoline/diesel. The stations are already there, they just need to be converted. Hydrogen distribution will mostly reuse natural gas infrastructure. On the

Which is why hydrogen cars need to be taken seriously. Not everyone is going to have access to a private charger, nor is it realistic to put up 0.5 MW chargers everywhere. There are millions of people that are better served by a car powered

Hundreds of buildings have collapsed. Even a few thousand will be the best possible news.

The difference is that a hydrogen car is much less resource demanding. It is the EV that is truly sustainable. We need to give them separate names like BEV and FCEV.

EVs are a mistake. They are unsustainable. In the long run, all car companies will have to shift to hydrogen, no matter what.

That sounds like a cop out. The article specifical mentions low cost catalysts. There doesn't sound like there is any credible argument for the whole process being always expensive.

Methanol would be made from hydrogen. It is functionally just another way of storing it.

There isn't enough raw materials to power all of ground transportation with li-ion batteries. It is a matter of time before hydrogen or a derivative fuel like ammonia or e-fuels becomes the future of ground transportation.

There are short-term issues like capital costs and a need for contracts to be set up first. These things can't happen instantly. But beyond that, it is entirely backwardness in thinking that is driving the opposition. Many people simpl

Even once in the lifetime of the airship will be millions of dollars though.

by _hypx 4y ago
Note that airships gain capacity with the cube of the dimensions. So if you can imagine an airship twice as long, that number increases to 64 40 ft containers. Actually more, since less room is taken up by scaffolding and equipment.

I'm really curious as to how they will solve the corrosion problem. They're basically building an electric arc furnace, but they're not using graphite electrodes. Instead, the electrodes need to be inert, and don't react

I'm sure they've tested it in extreme conditions. They just have gotten around to marketing it. Don't read too much into it.

That has a lot to do with how old many nuclear reactors are and that we have zero spare capacity much of time. People who are anti-nuclear have failed to realize how much of the problems are caused by rampant anti-nuclearism. Again, we are

by _hypx 4y ago
Just to be clear, the power from a nuclear reactor is very different than that of a wind or solar farm. Vogtle is 2GW of baseload power, and is comparable to significantly larger amount of renewable energy. It is also the result of decades
