All this means is car manufacturers will be heavily marketing all the countries that don’t ban the internal combustion engine.

Much in the same way the Tobacco industry continues to thrive and marketed around most of the world were there aren’t any restrictions

Global warming is a reality and needs to be addressed, doing so is not a gimmick or fad it's a necessary human and economic reality.
I don't think that the timescales under consideration seem unreasonable and with global efforts focused on battery development, peaks and troughs in power generation can be ironed out.
Well done to BoJo.

You been drinking again?

Re: [Updated] New petrol & diesel car sales banned from 2030
 

That's not an argument against these initiatives, though.

Furthermore, car manufacturers are wedded to profits, not a means of propulsion. If electric cars become cheaper globally through initiatives like these, then they will displace internal combustion engines in some countries where such initiatives are not taking place.

Re: [Updated] New petrol & diesel car sales banned from 2030
 

Yeah, the car industry isn't especially wedded to the future of the oil companies. A national transition to a new engine is an opportunity for them to sell more cars. These companies have been preparing for this for a while with a lot - if not most - already selling electric versions of some of their most popular models.

There is still another 10 years to go as well which is plenty of time for them to shift their focus.

How will they become magically cheaper?
Rare earth elements are rare.

Battery raw materials could face a supply crunch by the mid-2020s. Link
And that's just to supply the UK.:shocked:

There’s clearly a role for hydrogen fuel cells in cars. Hydrogen production is part of the strategy announced today.

Re: [Updated] New petrol & diesel car sales banned from 2030
 

So what's your solution to climate change and our ever dwindling fossil fuel supply? Get a bike?

Re: [Updated] New petrol & diesel car sales banned from 2030
 

And where will this hydrogen come from?
They still rely on rare earth metals for the electric motors.

Re: [Updated] New petrol & diesel car sales banned from 2030
 

We have oceans of hydrogen.

Re: [Updated] New petrol & diesel car sales banned from 2030
 

Of course, producing Hydrogen from those 'oceans' requires electricity in the first place.

Also, despite what some believe, burning hydrogen does produce emissions.

When burned in normal air, you get small amounts of Nitrogen Oxides, and of course, lots of water vapour.

What will be the effect of tons and tons of water vapour being added to the atmosphere I wonder (its a potent 'greenhouse gas').

Re: [Updated] New petrol & diesel car sales banned from 2030
 

More rain to provide water to create hydrogen from?

Re: [Updated] New petrol & diesel car sales banned from 2030
 

.. and more floods ...

Re: [Updated] New petrol & diesel car sales banned from 2030
 

It was reported that there were enough resources to replace the current global internal combustion engine fleet just about.

So given that replacing that fleet would take decades it’s not really an issue initially.

But roll on many decades.

Lithium-ion batteries recycling rate from used batteries to new is between 70-80%. That means diminishing returns of around 25%.

So, much like “fossil”* fuels, lithium is a finite resource and will run out eventually, we’ll be dead by then, but my Grandchildren will be buzzing around in their classic 2019 Mustang that i will have left them.

* if you believe oil to be a fossil fuel, for which there is no evidence.

Re: [Updated] New petrol & diesel car sales banned from 2030
 

If you produce hydrogen by electrolysis of water, first of all you can do it with excess electricity production from the grid, given the massive increase in offshore wind that’s being proposed. If you split water into H and O2 then all your fuel cell does is recombine it. There is no net increase in water in the environment because you’re just putting back what you took out. Any chemical impurities can be filtered or chemically altered in the vehicle exhaust system just as is the case now.

Besides all this, there’s no need to worry so much about lithium because we’re not very far away from a practical lithium-sulphur battery that has the potential to double EV range - or half the size of the battery required.

I think we’re going to see a future of mixed approaches to providing electric power to vehicles. There’s room in it for hydrogen and batteries.
