I suspect if E10 causes damage then by definition E5 must also cause damage, but will just take longer for the problem to manifest itself.

Or perhaps it's got enough ethanol to cause as much damage anyway.

The Telegraph now reports Audi is scaling back EV production due to lack of demand. I believe Volkswagen have already done so. Battery technology is just not good enough.

Nio's Battery swapping may solve the brick problem when the Battery fails to accept charge after a decade depending on what contract you have with them as well as the issue of queues at charging points and if you can buy a plug-in Nio, it might offset the issue of being tied to a monopoly supplier of batteries. You'd also have to ensure it has LiFePo4 so that it doesn't burn down your garage.

However, there's still the issue of batteries needing to be warmed up when cold and cooled down when hot, though that's only a major issue if it won't accept charge when it's cold. The only remaining issue is the weight, with some concern whether multi-storey car-parks can take it.

I've found Toyota are better than Lexus. Lexus seem to see you as an open wallet.

While Jamie Lee Curtis raves about her Honda Clarity HFC, Rowan Atkinson says he feels duped for buying a Battery car.

Actually, I was thinking it would put the cat amongst the pigeons and force utility companies to offer cheaper electricity tariffs.

Here's a thought!

What if your hydrogen fuel cell car comes with a 13 amp socket and hydrogen is cheaper than your electricity tariff?

Le Mans will accept hydrogen cars by 2026 apparently. So they seem to believe that's where we're headed. Anyone daft enough to buy a Tesla will be seething, especially when the Battery won't accept charge any more, which is likely to be very soon.

Nope!

The worst I've ever seen is a semi-truck tyre explode on the motorway.

How long do hydrogen fuel cell stacks last in the real world? 

Well, since you ask, I've owned a hydrogen fuel cell for the last 450 years and it still works as new.

Out of interest, how long did it take to achieve a full charge from a domestic socket? Looking online the Model 3 takes 24-36 hours to fully charge from empty from a UK domestic socket? For a weekend trip that seems like an awful lot of inconvenience?

Is that what you meant, as I’m in the middle of a 400 mile round trip in my RX and will only have to fill it up once at the start and again at the end. What’s the range of your Tesla?

Just curious really to fully understand…

Charging time for a Tesla Model 3

Charging method	Typically found at	Charging time*
Empty to full
3-pin plug	Home	24 - 36 h
3.6kW	Home / Work	15 - 22 h
7kW	Home / Work / Public Locations	8 - 12 h

. . . and isn't the model 3 the one with the smallest Battery?

Wow!

And the guy rushed back in with a carton of . . . . water?

Doesn't lithium react violently with water?

When Teslas spontaneously combust, it takes HUGE amounts of water to douse the flames.

All stores of energy can combust.....laws of physics can be mitigated but never bypassed.

Hydrogen is what fuels the sun, its the most reactive element in the periodic table. Luckily the world has never seen a Hydrogen bomb used in anger, but let's use it for personal transportation, what could go wrong?

Well at least you've disproved the propaganda claiming hydrogen is difficult to store or transport. But I knew that anyway. Hydrogen was part of the town-gas decades ago transported via the gas grid.

Sam, any idea how many cars catch fire in the UK per year? How about 100,000.- or 300 each day. 65% is arson or crime related but the rest is petrol and diesel cars going up in smoke mainly due to accidents or bad maintenence. Batterycars are not more dangerous.

Hey! That's absolute figures not proportionate ones. There are FAR more ICE cars than Battery powered cars. GM even told owners of their Battery EV to not park within 50ft of anything in case it spontaneously combusts.

Chinese car manufacturer www.nio.com has been doing this for some time and made it their unique sellingpoint. They own battery swap stations that are fully automated and you can change your battery within some minutes. However i dont think it will catch on in Europe as chargingtimes have come down drastically with more powerful chargers of 3/450kw and cars that operate on 800v architecture. 10 to 15 minutes charging will give you a couple of hundred miles.

 

The charging times is not the issue alone. Having a monopoly supplier for your batteries isn't a good idea.

You can't just say that from such simple statistics.

Americans were complaining that they could set fire to water because fracking was introducing flammable gases into their water supply. That doesn't mean water is dangerous too.

What makes batteries so dangerous is that they catch fire when you're not mistreating them. Airlines banned transporting them in their cargo holds.

CNN reports of a Li-ion Battery on a escooter exploding in a London house:

Perhaps Gang is desperate to sell his Tesla.

As I was typing above before I read the daft reply from Gang. An american company has revived the idea of Battery swapping. This is just an admission that Battery EVs are a huge mistake. As John has pointed out above, batteries have a limited life-span. One Tesla owner blew his up rather than pay the €30,000 Tesla were asking for a replacement Battery.

The Battery swapping idea is just an admission that having to wait hours and possibly in a queue at a charge-point means you don't want to own a Battery EV. Obviously, we're being corralled into Battery EVs and heat-pumps for heating to encourage us to buy solar panels and wind turbines.

EVs in the UK seem to work fine in winter, any idea how hydrogen fuel cell cars manage a UK winter, so real life experiences you can share would be great :).

So, after all the demanding of a straight answer from Malc.,you offer a facetious answer yourself!

Can we have a straight answer please?

Nice car. I've seen an earlier american video several years ago and it was only $5 per kg, the video shows it about $15!!! I'm guessing costs have gone down not up. So they seem to be profiteering.

I've also read that the only maintenance is a filter change. I'm guessing this is the air filter as nothing else goes in. So you buy on on eBay for say, £20 TOPS, undo a few clips and that's it your annual maintenance is DONE. I'm guessing this is why they're thinking of making ICE engines that burn hydrogen. I've always thought Lexus sell their cars cheap but make the money back on maintenance and/or it's a trick to generate jobs.

An american start-up wants to swap batteries and is agreeing with manufacturers to make their batteries swappable. This might be an improvement over manufacturers swapping batteries as it doesn't leave you chained to one supplier.

There was also a Tesla owner in the US who tried to charge when it was very cold and the car wouldn't let him. Several hours later he came back and it hadn't charged at all, it was still supposedly trying to warm up the Battery but somehow failing to do so.

Lamborghini have released their huracan sterrato.

So is the proposed ban on ICE cars to make us make do and mend rather than buying new?

Toyota have produced a revised version of their Mirai and BMW have announced hydrogen products too, though I'm not sure at what stage they're at. So it looks like they're downplaying hydrogen but quietly developing it.

As I understand it, Hong Kong already has hydrogen buses. Didn't the 2008 Beijing Olympics feature Mirai cars?

UK wide HGV and Bus and van Hydrogen powered vehicles ….. and at Ocado sites too ….. so tell me, coz I really don’t know this ….. is there  any reason why cars cannot refuel at HGV and Bus and van refuel points ??

They may make it similar to red diesel; only for commercial vehicles. The House of Lords has already criticised those giving false hope for hydrogen boilers in homes and hydrogen cars, even as the Telegraph (if memory serves) has announced the gas grid will install plastic pipes for hydrogen. Not sure how town-gas managed to supply part-hydrogen to homes decades ago. So it looks like they want us to buy Battery EVs (possibly to encourage us to also buy solar panels and wind turbines) and then about ten years on find that the Battery won't accept charge any more and only then buy a hydrogen FCV.

Whilst we all wait for the fantasy that is BP hydrogen refueling stations to reach the real world of adults, just the number of DC EV rapid chargers in the UK built by one company is multiplying like rabbits.

I look fowards to seeing hydrogen fuel stations reach similar numbers, end of this year or next? What's peoples bets on here? 🙂

Actually, the hyperion youtube video I posted featured a mobile hydrogen filling station. As it's probably billionaires who might buy a hyperion, I'm surprised they haven't bought one of these along with the filling station. As well as having a 1,000m/1,600km range, that largely solves the scarcity of hydrogen filling stations problem.
