Why, the cars can be charged during off peak times, the electricity demand starts crashing by 9 at night, and most peoples daily commute would only take less than2 hours of charging,
the power stations owners would love it, steady electric demand through hours that traditionally are loss making.
This crystallised material holds the promise of revolutionary liquid solar cellsBut I'm pretty sure by the time EV are widely available, they'll managed to infuse solar panels into the car itself.
Yea, but most people would charge the moment they got home right?

you would be better off adding an extra panel to your roof of your house, so it catch rays all day (generating revenue), while you car is parked in the garage.
That sort of eliminates the idea of driving the car to work...
.
Yeah, but that doesn't mean they have to start charging right away when you plug it in, off peak loads can be managed, you can program it to charge at certain times, or with the smart grid the the electric company can choose when to set the cars charging managing the load through the night.
they have them already, but there is just not enough surface area on a car to make enough energy to make it worth while.
so its a bit of a gimmick and not really practical.

Current solar tech won't do it, new advances might though.
If solar conversion rate get high enough, that spray-on potential... it could get to a point where battery packs can be reduced, lighten up the load/weight. But every bit help if the tech get advanced and cheap enough.
Why isn't cost a problem with renewables? renewables aren't free, they take a massive capital investment to set up, which has to pay for itself, So whether you are building an oil rig or a wind farm, you are building expensive infrastructure that has a limited life, that needs to generate enough revenue to cover its construction, running cost and a return on those invested funds.
Have you done the numbers on whether you could profitably run a wind farm and produce hydrogen? eg can a $100Million wind farm generate enough hydrogen to make the investment in both the wind farm and the conversion plant worth it, if not where is all this "excess" electricity going to come from, people aren't going to keep adding infrastructure once a glut forms.
You seem to miss the point that using the electricity to create hydrogen isn't as efficient as just using the electricity to charge a car.
eg, if you can get 1000km's out of an EV, using the same amount of electricity it takes a hydrogen car to move 300km's, what is the point of adding the complexity of a hydrogen network?
They have to be backed off as the load reduces due to frequency constraints, this wouldn't be required if they were producing hydrogen during off peak periods.
Jets can run on hydrogen, but can it fly?
I probably should look into that. Heard the US currently has this system on its subs that separate the H from the o2 in the water as it passes. From memory they only uses the o2 for fresh air.
Pretty incredible the tech that's out there but not yet mass-marketed.
There is no problem with charging time.
There is no problem with depleted battery waste.
Hydrogen can be used to power turbines,
you can even burn it on your kitchen cooktop. You can't do any of those things with batteries.
It wouldn't be required if they had a bank of 9,000,000 cars and other vehicles across the nation ready to be charged either, not to mention other batteries in businesses and utility scale ones ready to take any cheap off-peak loads that come their way.
Cars are parked for more hours each day than they are driven, especially at night.
A national fleet of parked cars and other large scale batteries awaiting charge, could be used to completely level out the off-peak demand.
during the Peak times, Cars would stop charging and home and businesses with batteries could use their batteries, then as demand slows the electric companies starting charging cars and batteries all night.
the end result could be a completely stable demand level, even through production fluctuates from renewables.
Hydrogen at this point of our evolution, is the best most versatile and cleanest fuel available, it is the only one that can replace oil based fuel in most instances.
The only thing is the cost to produce it, but that cost will come down as more plants are installed, to make use of renewables.
I am only talking about Cars and trucks etc, these will operate more efficiently with batteries than with hydrogen, not to mention they are on the market now, if hydrogen was the answer, there are plenty of big balance sheets that would be making it happen, So far nothing is happening (in the vehicle space)
The next step in air travel, is Sydney to London in 4Hrs, the technology being developed is scram jets.
These run on super cooled hydrogen.

https://www.newscientist.com/article/dn16682-air-breathing-planes-the-spaceships-of-the-future/
The technology isn't new and is still in development, but I think has more potential than an airplane full of AA batteries.
Just my opinion.

Maybe, but those increases would also be increasing the effect of regular roof top solar, Meaning you would be even better off having the solar panel on the roof exposed to the sun.
I mean if your old style panel is going to produce 500 Watts on car and 1500 Watts on the roof, then the new style might make 1000 watts on the car and 3000 watts on the roof.
The increasing efficiency has increased the benefit of roof top, at first having it on the car meant you lost 1000 watts due to practical issues, but now you would be losing 2000 watts.
O.K if every car and every truck and every house is going to have lithium batteries, how long will the lithium last, it is a fairly scarce material, when compared to most.
Recycling is never 100% and recycling lithium costs 5 times more than producing it by the the brine based process,.
So how is that going to affect costs, going forward?
The reason hydrogen isn't being produced large scale at the moment, is because fossil fuel is readily available and already in use, as it it phased out a long term solution will force hydrogen production.IMO
Read that Concord was in use while Boeing's version was abandoned because Boeing designed theirs to go across the US continent while Concord goes over the ocean.
So hydrogen relies on fossil fuels becoming more expensive before it makes sense, while electric vehicles already beat Oil on running costs even at all time low oil prices.
thats a pretty important fact right there.
Not to mention that battery tech is improving rapidly, in the not to distant future batteries may have almost unlimited battery cycles, I mean the battery will already out live the car, but it may out live the owner in fixed locations such as homes eventually.
