Is the end of Battery EVs coming?

We will not be here to see, but the long term impact on the planet is much higher with BEVs than Hydrogen EVs.

Also you can have internal combustion Hydrogen engines.

You know that electric cars are almost as old as internal combustion cars right? but they didn't take off in the 1900s, one of the reasons was politics...

It is hard to tell what is going to happen, too many politics and companies control the world... and in fact that is what is going to decide what is going to happen.

Yes, the people here are quite knowledgeable :)
Fossil Fuel politics killed the GM EV1 which was going to be successful - people bought them, liked them and wanted to keep them. But GM were forced by the US Government to buy them all back and destroy them ! (From 1996)

If we are over-producing renewable energy you could direct this to electrolysis of water to generate H2 but that may mean supply is unpredictable for the amounts required for transport. You still have the logistics challenges. You’re still burning something which I guess (but don’t have evidence to hand) is not completely clean for air quality.

If burning it in the atmosphere in reality it isn't completely clean, mostly producing water vapour but also a small amount of nitrogen oxides and a tiny amount of CO2 (vastly lower than burning hydrocarbons), a completely pure reaction doesn't produce CO2.

The best use of it will likely be time shifting renewable energy production than transport - current efficiency is about 15-20% but 30% or more is achievable.
 
Anything you burn really is going to be dirty in some way, but it might be such a small amount it makes no difference in the open air.

Even using an electric motor produces ozone (bad at ground level), from sparking in the atmosphere.

You mean like petrol that gives off the following metals.
Antimony.
Arsenic
Beryllium
Cadmium
Chromium
Cobalt - shh that kills the ev argument.
Manganese
Mercury
Molybdenum
Nickel
Selenium
Vanadium.

that sounds like the list of materials i need to find in the videogame Elite Dangerous... who knew all i needed was to attach a bag to someones car exhaust :D

Car ownership in the future will likely look very different from how it is today. Automated driverless cars that you order as and when you need them from your phone. If you consider that most cars are parked up for 99% of their lives, it's a very wasteful purchase.

I would imagine that EV fleets wouldn't work for this sort of model, without some serious infrastructure cleverness (I'd like to imagine cars recharging overnight via renewables, giving back to the grid in times of demand).

It would never work as companies would never have enough cars to service demand at peak times due to the majority (99%? :D) of cars being parked up during non peak times.

If you do not have enough vehicles to service peak demand then you end up in a situation, where the service is unreliable to the user and pushes them back towards private ownership due to the reliability of having their own vehicle.

initially at least could split the difference. even getting the average household down to 1 car, and then dial a car for the times when a second was needed, that would still hugely cut down the number of cars litering the roads (as well as the materials needed to build them)

you can kind of do that now and indeed a couple in my wifes team at work do just that, they rely on public transport most of the time (they live in Cambridge which is well serviced around town and with good rail to london and there is a free work bus) then hire a car if they want to go away for the weekend............ but it is a lot more hassle than what people here are hoping for the future.

The biggest change I see from driverless cars, is a car being able to solve the need of both parties in the household without having to consume time of one party in service of the other party. (There might be a better way of wording that)
For example one party in the household goes to work, they take the car to work and then the car drives itself back home. The other party in the household now has access to the car for what ever they need. Whether that is going to work at a later time or running errands. The car is sent to collect the other from work at the end of the day. One car used by both parties without the need for a person to pick up or drop the other off.

I do not believe that driverless taxis or busses will radically change the service of busses/taxi when compared to what we have now. Hence I do not think that driveless taxi/busses will radically change car ownership.

That's better, I knew you had it in you Chuk. :D

it is a good point and would really help us... for instance both my wife and i work on the same research park...... however since having a child we cant go into work or home together because one of us has to walk the lad to school and pick him up after, but a self drive car would easily be able to service both of us, so one of us could go into work bright and early, and there would still be time for the car to then go home and be ready to pick up the other parent after the school run was done, then the same for the homeward journey

Self driving cars have reached a dead end. They can't figure out how to make them not run kids over and do other random, dangerous stuff. Or get completely shut down by someone placing a cone on the bonnet.

The focus is shifting towards removing the need for journeys in the first place.

There was one not long ago which ran a guy down, decided the obstacle had gone, then dragged him down the street. AVs do that kind of thing. The problem with a computer program is it will always make the same mistake in the same situation.

There is a reason they have vanished from the news

Yes and loads of them in SF get rendered useless by pranksters putting stuff on their bonnets. Like I said.

When they are moving, they often get stuck and block roads, especially around roadworks and busy junctions. As soon as they meet something which isn't a clear street they break.

They got set in fire too. Like you my said next, like anything 'said' by Masher means anything. How long have you lived in SF to be the authority on this exactly?

If someone smahed the screen or stabbed the tyres in your car you would have the same issue...

Mashers are gonna Mash.
