Disappointing.
As well as HFC engines it also has hydrogen ICE cars. I want cars powered by electric motors where you get HUGE torque, only one gear and NEGLIGIBLE maintenance.

hahahahahhahahah ............ Reality Gives methinks !
great hype tho' for the hypertension methodology .. reminding me of the Ruskie Hypersupersonic indestructible mach 10 ? missile that's invincible ......... BUT one's just been shot down by Zelensky and co OK .......... 🖕
as I say reality " Gives " ..... let's stick with Toyota's Mirai style relatively simple and straightforward and readily achievable sensible cars for the masses ............. well maybe me anyway if i live that long 🤣 ............. and I can rebadge the " sedan " to a Lexus Ls700
Malc
But who's telling the truth?

The Hyperion's 1600km/1000mile range would make it easier to roll-out the hydrogen infrastructure. It would make it worthwhile to go on a long trip to fill up, which only takes 5 minutes. It only weighs as much as a small car because it's carbon-fibre and titanium.
The only problem is price.
Also the video, suspiciously, doesn't show it going around a track despite claiming a 0~60 time of only 2.2s and a hypercar top-speed. What gives?

You have to ask why the Hyperion isn't making bigger waves in the media.

I know Malcolm, but it took less than 10 seconds to find those above.
Not sure why it appears hard for some to acknowledge that this information exists?
Perhaps a mixed future, enjoying the best of all fuels could be achieved?
It's not a case of it existing. It's whether or not it's the information that one is looking for.
As it turns out, it isn't. It looks like they're only catering to heavy duty trucks and not cars.

Gang, you're simply purposefully ignoring the BP production in the north of England to roll out availability of hydrogen to each of it's 1200+ estate as a minimum ....
Malc
Do you have a linkt to any news on BP's hydrogen roll-out?

As long as the moon is circling the planet the sea will have high and low tide, which is enormous power, and all that need to be done to turn that into electricity enough to make hydrogen, that is a power source that is recycling itself going back to water to be reused, is a bit of hardware.
Actually, the Moon is slowly drifiting away.

BYD Seagull is sub-£8000 electric supermini for China
Four-seater is smaller than the Ford Fiesta; offers up to 100bhp and 252 miles of rangehttps://www.autocar.co.uk/car-news/new-cars/byd-seagull-sub-£8000-electric-supermini-china
Other articles claim it's 0~60 time is 5 seconds and it's less than 4m long. The larger Battery is only 38.88kWh, so presumably it will be cheaper to replace, assuming these things CAN be replaced.

Small HGVs are being banned from 2035 and large ones from 2040, ALLEGEDLY. But so far there's no infrastructure for hydrogen. Tesla's semi takes a MEGAWATT. Imagine the queues for that!!!!
Eventually, they'll have to roll-out hydrogen for industrial usage. Then the filling stations will want the extra income from fuelling cars too. It's just the government who want you to buy heat-pumps and Battery powered cars and then "all by yourself" figure you need solar panels and wind turbines, when you get a huge electricity bill.
It'd be nice to have your own electolyser and then power your house and car from the sun, wind and rain!!!
Apparently hydrogen fuel cell cars only need a few filters changed for servicing. Batteries lose their capacity to hold charge resulting in a huge bill to replace them. Battery swapping means you're a captive customer.

There's no way the grid can take all of us owning Battery powered cars.
After several years, your Battery pack won't accept charge any more and you've got a very expensive brick.
Large vehicles don't work with batteries. Elon Musk has a semi. But get this, it takes 1 MEGAWATT to charge it. There's just no getting round the huge amount of power to charge batteries.
Eventually the hydrogen filling stations will want to attract car owners rather than just truck drivers.
They're (apparently) rolling out plastic lined pipes for the hydrogen on the gas grid. Heat pumps don't work ESPECIALLLY if it gets cold.

So does that work then?
Do you place the burgers directly on the solar panel to cook, and the wind turbine cools the outside so they don't burn? 🙂
Aaaargh! You're making fun of me!

They're LITERALLY where the rubber meets the road; about 16 in² each. I don't like to gamble which is why I would never buy a Tesla.

I've just read (in the Telegraph?) that some are closing down. But we know the House of Lords has protested against giving hope to those of us who want hydrogen cars.
The only Battery powered car I might buy would be where you can swap the Battery as after several years, it loses the capacity to hold charge and you're left with an expensive brick. But that requires renting the Battery and you still have to queue to charge, you still have to warm the Battery when it's cold and cool it when it's hot. Most now, apparently, have heat pumps as a heater drains the Battery too much.

You know what Samantha you're right. What's all the malarkey about. I've seen articles saying that those plastic pipes aren't up to the job for hydrogen as the particles are so much smaller than natural gas that hydrogen can seep through the plastic. Geez there's too much negatively towards anything nowadays.
Town gas was partly hydrogen. Are we supposed to believe the hydrogen molecules couldn't get past the methane molecules and escape?

I'vre read two articles now about how to save on energy costs; one from the Independent and one from the Telegraph. Neither mentioned induction hobs.
I've had a ceramic pan for a few years but could never fry burgers; only boil them. Now it works fine on the induction hob. In fact, I have to turn it right down to the lowest setting of 200W as burgers need to be cooked right through without burning the outside.
All the ceramic pans I've seen in the shops are induction ready. But whereas they claim they're suitable for all hob types. They're only good for induction and probably gas.
Clearly, the propaganda wants you to invest in solar panels and wind turbines. You're supposed to buy an EV and heat pumps, only to then get a GINORMOUS bill for electricity. So a light bulb appears above your head and switches on and "all by yourself" you figure it would be a good Idea to get solar panels and wind turbines.

The Telegraph reports that the gas grid will have plastic pipes installed for hydrogen. The article also claims boilers will be hydrogen ready by 2026. Yaaaaay!
So what was all that marlackey about banning boilers?
-
The Telegraph reports that the gas-grid is being replaced with plastic pipes for hydrogen transportation and boilers will have to be able to run on hydrogen by 2026!

Quotas have been imposed on fruit and veg. This looks like the scene in the movie, The Sting, where they use the "shut out". The mobster arrives too late at the betting booth to lay his bet. So the next time, he panics and places his bet without even thinking. Panic buying may mean you don't even look at the price.
The quota doesn't even make sense. You can buy the limit of three, then drop your shopping in the car and go back in or go to another store to buy the same again.
Panic buying of toilet paper during the Covid-19 lockdown would mean you might buy more expensive loo rolls.
The lockdown now looks like a trial-run for when we "own nothing and are happy". In other words, when we no longer have cars and don't travel.

It appears that you are suggesting that the same facility that is currently used for other gases can be used to store hydrogen as is? If so, that's an 'interesting' statement. I presume you read that somewhere, so I don't suppose you could say where please?
From Centrica's own site (they own Rough):
"Centrica is advancing plans to convert its Rough offshore gas storage facility for hydrogen storage as part of its transition to a net zero future."
https://www.centrica.com/media-centre/news/2022/centrica-re-opens-rough-storage-facility/
"Centrica’s long-term aim is to turn the Rough gas field into the largest long duration energy storage facility in Europe, capable of storing both natural gas and hydrogen."
Neither of these claim that Rough is ready to store Hydrogen or that it can do so in its current state.
Huh?
Where did I say Rough could be used "as is"? I stated it was being considered for hydrogen which is all that your own links also state. The point I was making was that natural gas is stored there without being super-cooled.
I mean, do you enter a bar and five minutes later people start crashing through the windows because you've started a brawl?
The Rough facility is just an undersea cavern. There is nothing they can do to change it that would make it more suitable for hydrogen. I'm not an expert but I'm guessing that at most only the faciiities used in pumping the hydrogen into Rough would have to be altered.
The bottom line is that if everyone adopted battery-powered cars the grid would undergo a melt-down.
Hydrogen CAN and WILL be stored and transported at a third of the cost of transporting electricity over the grid. The gas-grid can be modified to transport hydrogen, presumably in un-compressed (or not very) and un-cooled form.

Yes, it's looking like hydrogen is making some big strides now for commercial vehicle use (and aircraft, ships etc.) which IMHO means that the technology and economies of scale will accelerate and any remaining technical hurdles will quickly get resolved.
With the recent announced interest in hydrogen fuel cells again from a number of large and influential car manufacturers then trickle down to personal automotive is already underway. Regards the hydrogen infrastructure, then that largely exists within the existing fuel station network (so long as commercial deals can be done of course) as large scale hydrogen production will be needed for commercial (and possibly office/domestic heating etc.) and so not a huge leap to start and create the distribution to existing and/or new fuel station sites
Let's face, with the dismal roll-out of electric charge points in this country (and many others) actually creating a hydrogen distribution network when both commercial and many automotive manufacturers are starting to back it, which will likely bring in the major fuel providers too, is a more likely proposition than the hot-potch and fragmented underfunded network of electric chargers ever been up to the task. I've been to a few motorway services areas recently in the south of the country - these are busy motorways and yet the number of charging points was only 4 in each... Yet there were some 12 - 18 fuel pumps... (even if due to their ludicrous price of fuel they were largely unused). And at busier times those 4 electric charger points were busy with people waiting - I didn't stay for more than 1/2 hour at the services but the same people were still waiting for a charger to come free when I left - and then they would also have to wait for the car to charge too!
I suspect owners of Battery powered cars will be left high and dry.

That's not true.
The Rough storage facility, Britain's largest doesn't store natural gas as super-cooled, LNG and was recently considered for storing hydrogen.
I also read about a hydrogen filling station several years ago, in America, the price was about $5 a kg. So you could fill up a hydrogen fuel-cell car for about $20. I don't know how they stored the hydrogen but they seem to have overcome any difficulties.

This site explains it well:
"Hydrogen is difficult to store due to its low volumetric energy density. It is the lightest of and simplest of all elements, being lighter than helium, and so is easily lost into the atmosphere.
Another challenge is the very low boiling point of liquid hydrogen (−252.8°C), which means that it needs to be kept cryogenically stored at low temperatures. Storing hydrogen as a gas also has its challenges as it typically requires the use of high pressure tanks (350-700 bar or 5000-10,000 psi)."
"However, there are still hazards related to hydrogen that mean additional engineering controls need to be put in place to ensure its safe use. With a lower ignition energy than petrol or natural gas, hydrogen has a wide range of flammable concentrations in the air meaning that ventilation and leak detection are important for hydrogen systems. Special flame detector are also required as hydrogen burns with a near-invisible flame. Material selection for hydrogen systems is also important as some metals become brittle when exposed to hydrogen."
So, as you can see, some difficult engineering challenges need to be overcome before hydrogen becomes commonplace in forecourts.
That's not true.

The cash for clunkers scheme and more recent claims that second-hand cars were getting better prices than brand-new models shows the policy. But Battery powered cars are not the answer. They certainly can't make huge semi-trucks Battery powered. Imagine getting stuck behind a lorry at a charging station. I once returned from a skiing trip and the coach coming down the mountain had to stop for petrol. My window was opposite the fuel pump and I watched as the petrol just kept on flowing.
Hydrogen fuel rollout.

You're joking!
Cam belt changes, oil changes, transmission oil changes, spark plugs, de-coking, etc. And ample opportunity for the clowns supervised by monkeys to trash your car.
