I doubt that. I've got a Leaf that I've had for almost 2 years (i.e. lots of rubber on the road), and I'm not going back. Judging by the number of Teslas I see driving on the road every time I'm out, I don't think other people are going back either. This is in Minnesota too, with very icy and cold winters. I've seen that commonly brought up as an anti-EV talking point, but it's empirically wrong.

Hydrogen has the same infrastructure as gasoline. A "recharge" takes as much as 40 seconds. EVs have a negative impact in the quality of life of those who buy them because they cost more and have the problem of recharging time. It's simply an own goal you are doing to your team which in this case is your family because of woke ideals. Lower mantainence costs is also a legend unless we are talking about Toyotas and Be…

I own a LEAF. The maintenance costs are basically zero: just tire rotations. It pains me to think about spending money for oil changes on my other car.

Also the build quality on a Nissan is as good as a Toyota.

If you'd rather have a car that's twice less efficient (and twice more expencise to fuel) than wait 20 minutes to charge, then you are living in a bubble of privilidge that does not reflect life priorities for 90% of folks out there

EVs are perfect second cars or city cars. You don't need to charge them completely all the time. If you want to take a road trip then get a PHEV, or a Hybrid.

You can now, but it doesn't scale that well if electric car usage increases 10-fold for example (which is still a very little fraction of total).

The number of charging poles I see in public and store parking lots has literally increased 10-fold over the past 3 years. To the point where I always see several free charging points every time I bother to look. I'm reasonably convinced that this scaling can continue at the rate of electric car adoption.

I've seen that too. 20 instead of 2. Can it go to 200? Not really.

It is, but it doesn't have to be. It is possible to make H2 from H20 and sunlight. At the moment there is little market for such "green" hydrogen but the hope is that hydrogen-based transportation will create that market. Imho I cannot afford to be a market leaders in this field. Until H2 is available everywhere, including at remote locations during Canadian winters, I'll have to stick to gas stations. (I have yet to…

While technically true, the conversion is inefficient. It takes a lot of power to extract H2 from H2O. You could just use that power directly. The problem with electrics in -50 is keeping them plugged in when not in use. -50 is very extreme though, you’re talking far north or Edmonton.

But it is much faster to fill-up an hydrogen tank then it is to charge a battery.

Hydrogen makes much more sense for container ships, where electric batteries can't be made practical, but hydrogen storage can be scaled easily.

I agree also perhaps for grid scale storage

Or aluminium smelters.

Actually it is possible to make gasoline with solar panels, water and carbon dioxide from the air. Making synthetic gasoline was already possible before WWII and that was used a lot by Germany. It is true that making hydrogen is easier, because making gasoline requires additional steps and equipment, but due to the large disadvantages of storing and handling hydrogen, making gasoline is nonetheless preferable and it…

Or just charge a battery with the solar panels at much greater efficiency.

For short-term storage a rechargeable battery is certainly preferable.

For long-term storage, the battery auto-discharges, so the efficiency drops quickly with the storage time, until it becomes much less than for storing the energy by synthesizing some appropriate chemical compound.

For storing solar energy, both short-term storage (e.g. for a day or a week), like rechargeable batteries, and long-term storage (e.g. for a year or more), like synthetic gasoline, are needed.

> “I was constantly checking the Nexo’s efficiency readout to maximise the distance I was getting per kilogram of hydrogen. I found that by using techniques from rally driving, such as looking as far down the road as possible, as well as tips I have learned from my dad for driving a truck efficiently over long distances, it’s actually possible to go way beyond Nexo’s official range.” Anyone have some insights on this…

Yeah, nowadays it is part of the course when getting driving license (here in Sweden). Economical driving is an important factor when taking the test eventually after the courses too. It is one of the 5 big factors you need to pass. As it is mentioned above, you need to look far and plan ahead, do engine braking, let it roll on its own if it is redlights etc etc.

Would be good to have this implemented in the curriculum in Canada & US. The amount of times I've been honked at because I was approaching a red light without hitting the gas, only to have the person behind me speed up and overtake me then slamming the brakes as they approached the light is ridiculous.

Hydrogen is the future of electric transportation!

Imagine you are driving and you have several cartridges of magnesium hydride and when you pass by a refueling station a drone catches up with you and swaps nearly-depleted cartridges one by one all while you continue going! How cool is that! B-)

And then you can refuel by stuff that you produce yourself using photo catalyst solar panels in your back yard.

> anyone could trivially break the record "Make it bigger" doesn't really work in cars, otherwise range anxiety wouldn't exist as a concept. The record still makes sense because the Hyundai Nexo is commercially available and it's not a prototype with a comically-large just for the record tank.

“Make it bigger” does work, but it increasingly stops resembling a car. Check out the range this one can get on a single tank of hydrogen! https://en.m.wikipedia.org/wiki/Atlas-Centaur I don’t know what you’d consider the max range here to be, but it’s definitely better than 887km.

Excellent range. And to the point of the comment, said linked vehicle is a production vehicle where the tank was not added for the sole purpose of breaking a record, so... ¯\_(ツ)_/¯

FWIW: the material challenges for hydrogen are such that I do not think that it will ever be a mainstream storage medium for vehicular use (it's not a fuel, it is a battery).

- hydrogen embrittlement

- leakage from whatever container you plan to use

- very low activation energy -> always danger of explosion

So it's a great thing in the lab and to get subsidy for but it sucks for large scale deployment, and deploying it in devices that have a long projected lifespan has its own special class of problems.

Plenty of manufacturers have already had hydrogen test fleets and as far as I'm aware all but a few have been abandoned.
