How Can This Work?

Post by Strangways » Wed Feb 12, 2020 1:59 pm

The government are now targeting 2032 for the ban on new petrol and diesel engine cars and vans, which also includes hybrids.
So you live in a block of flats with no off road parking and 3 people in your family have cars. Or maybe you live in a house with no off road parking.
How do you charge your car? Am I missing something?

Long extension lead and a brick to hold the main security door to the flats open?...
I agree, until the infrastructure for charging is sorted I can't see how the average person can own an electric vehicle?

Don't worry Hydrogen will be the future.

The problem with Hydrogen is it takes nearly 4 times the amount of hydrogen to the air to ignite then "standard fuel" cars do. So are they going to increase the fuel tanks by 4 times the size? Not only that but hydrogen does have a higher flash point, it's less volatile, so getting it to ignite is 100 times harder. If I recall the flash range for hydrogen is about 0.8, but gasoline-based fuel is 7.8.

It's also much harder to store. And if it does go wrong it's near impossible to put out. Most fuel stations don't have the required safety features to properly store hydrogen over liquid fuels.

All I'll say on this, I'm glad theirs much smarter people then I trying to solve this one :p.

Just remember the ban is on selling new cars. They won't stop selling petrol or diesel used cars and if you already own one you can still use it, they'll just add a higher tax to it.

I guess the value of used petrol cars will go up. Maybe I should think about investing in a few nearer the cut off date!

Hydrogen cars doesn't burn the hydrogen like normal fuel but instead convert it to electricity in a fuelcell.
The car itself is then powered by an electricmotor.
The hydrogen is stored in a compressed tank and the range is about the same as a medium sized car (around 600-700 km), filling takes about 4-5 min.
The main problem is the fuelcell, which uses platinum and the energy required to make the hydrogen.
And the cars are really expensive at the moment.
