How far travelling a Hybrid with no petrol

There's certainly an asda here that is un-manned (no kiosk at all, I think it has to have remote CCTV coverage) and the pay-at-the-pump ones stay open after the kiosk is shut.

And I've already seen a queue of Teslas at London Gateway services waiting to use the "Superchargers".

I can only assume you've never owned an air conditioned car. I would never buy a car without it, having owned one.

I wasn't talking about the staff. UK regulations requires the driver holds the trigger on the pump nozzle for filling of Diesel and petrol. All latching devices (beloved by the fire prone gas guzzling USA car owners) had to be removed from the pumps for the public to safely use the pumps without a pump attendant. In the USA people goof off and then forget to remove the nozzle from the tank and drive off ripping the filler hose off the pump. Or they get a static charge and pull a spark igniting the fuel vapour that has been expelled from the open tank filler when they go to take the nozzle out. In the UK if you are not in attendance holding that trigger, stood out in a freezing gale, you don't get any fuel.

You can plug an EV in and walk away or sit/nap in your nice warm dry car. You can even make phone calls, send/receive texts/e-mail or use the internet while charging. They will switch the pump off if they see you doing that while filling with petrol or Diesel. I wonder what people will do with 1/2 hour to kill when they get an EV RV.

You can plug a FCV (fuel cell vehicle) in and walk away as that is a sealed filling system, locked on the filler port so is allowed to latch.

The ITM Hydrogen Refueling Station (HRS) being rolled out in the UK for public use does not serve 30 cars a day. It can serve 16 cars a day. They will have to install a larger or 2nd unit for 30 cars/day.

More FUD.

ITM HRS can only store about 15Kg of hydrogen so doesn't pose a big threat if blown up. About the same risk as 3 car petrol tanks. LPG filling stations with above ground tanks are a better target in terms of energy release.

As it can only fill 3 cars back to back if you are 4th in line then you have to wait 24/16 = 1 1/2 hours for it to make a tank full of H2. A HRS with capacity for 30 cars/day is unlikely to store more H2 for safety reasons so the wait for 4th fill will be 24/30 = 48 min.

There are less than 50 fuel cell cars in the UK and only idiots will be buying them at £60K a pop. The EV equivalent (OK with 1/2 the range but

The ITM HRS is electrolytic and uses grid connected electricity to make the H2 on-site. So a 30 car/day station will put just as much load on the grid as an EV charger that can charge 30 cars/day.

Well, quite. Skipping over the fact that "Mr. Cheerful" is an idiot troll, when criticising the safety of hydrogen fuelled vehicles, his ilk seem to conveniently forget just how dangerous petrol is, and we deal with that adequately.

IMNHO, the obvious solution is (are?) flow batteries. Then "all" a filling station would need would be the ability to pump liquid electrolyte in and out, a set of engineering problems already well solved.

Traffic conditions, at least here in the SE, mean spending long periods stationary or moving in queues very slowly. Even on a mild day, that's pretty unpleasant with no A/C.

The fundamental issue with fuel cell technology is that there isn't a single dealer on the whole planet that can service the hydrogen fuel system and the fuel cell.

Not only that but the RAC/AA/Greenflag can't do anything with them either. Just put it on trailer and take it to the maker.

There will never be a lower cost non-franchise service option and the only way of getting FCV will be on lease from the maker. That makes them worthless on the 3rd hand market.

I'm not entirely convinced the problem of 'repairing' batteries in either all electric or even hybrid cars is entirely fixed.

We are in the process of looking at a replacement car. We started looking at the Tesla 4x4. Two things convinced us it was a non-starter (no pun intended). One was the concern of getting stuck being unable to recharge it. The other was the battery/batteries seem to be so 'buried' in the vehicle that replacement / repair would seem to be either extremely difficult to impossible. In other respects, the claimed reliability seemed extremely impressive but, with a 'dead' battery, it is just a pile of junk.

We are currently looking at a couple of hybrids- a Merc and the Outlander. At the moment I'm in the early stages but the Outlander at least has a long warranty on the batteries (8 years for 70%) plus you have the petrol engine at worst. The Merc warranty is much less 'impressive', as is the performance- at least on paper.

We tend to keep our cars a long time, we buy one we like and 'get comfortable with it'- our current 4x4 is 11 years old and, having been 'looked after' will last several more years I am sure if we want it to- not least as he have several vehicles.

Both mine have air-con. I hardly ever use it. Unlike the heater.

I never used to, but my current car has climate control, and if left on auto runs the A/C pretty much all the time. It provides a reasonably stable temperature, and doesn't mist up easily, so I just leave it like that.

Petrol IS very dangerous, but it is a known danger, I am merely summarising a couple of ideas that occurred to me, hydrogen in the domestic market is not a known danger, and given its amazing powers to burn really well, I for one would want a lot of likely problems to be thoroughly sorted before (if ever) it becomes mainstream.

One plus for hydrogen is that when it burns, the flame is not so dangerous to be near (an explosion requires a mixture). This is because the flame is not luminous, unlike a hydrocarbon flame which is, and which therefore radiates a lot of heat sideways. You wouldn't have wanted to be near one of those Buncefield tanks.

However, no one has yet indicated in what form teh hydrogen is in the car. Liquid (seems unlikely), but if as compressed gas, at what pressure?

Yes. They are a lot safer.

Anything that detonates at car tank level is a big bang.

But methane and LPG are a bit less likely to, and no nearly as laeky as hydrogen

'Official' ? written by advertsing agencies?

ALL of it.

Nope, Hihe temp and pressure and a lean mixtire has nitrogen 'burning' top make Nox.

Yes.

High temps presures and a superfluity of oxygen due to lean burn

Petrol tems to limit air as well as fuel.

Its still bloody stupid and dengerous.

Hydrogen is the smallets atom there is. It LEAKS. #

The fact that it leaks through steel is an indication of the care required in its usage.

The filling pressure seems to be listed as 35 or 70mpa (10,000 psi) (that is dangerous in and of itself, no matter what the content is.)

The filling stations are extremely expensive to set up too.

Where in the Petroleum (Consolidation) Regulations 2014 are any other current regulation is that requirement ?
