All UK HGVs to be zero emissions from 2040

[minimutly]

This is one big stab in the dark - does it assume burning hydrogen? Or nuclear?

 

[octo0072000]

Just not possible they tried hydrogen truck in the 80s it could only run dept to dept due to lack of range and recharging/filling point lasted less than a year had a load of oxygen like tanks all over it

The driver shortage will have gotten so bad by then they'll all be parked up so emissions will be zero.

With a major shake-up of the transport system its achievable, leccy hgv`s are out there already. May have to get the long haul HGV`s cargo off the roads and onto the railways .

A bit like China stopping burning coal, It's never going to happen!

Will be way before 2040 for buying new. The new Mercedes eActros will run from one end of England to the other(well Exeter to Manchester at least), has over 500hp and will charge 80% in an hour, plugged in at a distribution warehouse bay and it will be more time efficient than using petrol stations. Admittedly the Mercedes’ does have some major drawbacks still, for example it’s only a 25t payload rigid rather than a proper lorry but that’s ready now.

By 2040 the whole cab will be replaced by batteries/fuel cells and nobody will know what a lorry driver is

HAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA

I'd like to see a DC that would allow an artic to take up a bay for an hour. 20 minutes tops to unload then away.

Lots of 3 phase sockets in motorway barriers for selfquiped charging hgv's.....


Plus loads of blocked motorways

 

[minimutly]

Mostly negative or pessimistic outlook then. Must admit I never thought it was possible, but the Merc is allmost there allready? Well, maybe not, if the payload is so small.
I still can't see how digging up most of Australia to make batteries makes sense tho? And yes, some might say what else would you do with it, but that's not the point...

quik maffs

485k HGVs registered in UK last year. Half of them maybe? 44 tonners
44t lorry 7.6 mpg average
500 miles travel (small range really) - 296 litres diesel
approximates into 2960 KWh potential energy
30% efficiency (being kind) = 888 KWh

Now lets disregard the electrical energy losses and assume you just need 888 KWh of electrical energy to take 44 tons 500 miles (in reality you need more)

"will charge 80% in an hour" - so 80% of 888KWh in 1 hour = 710KW quick chargers? REALLY? Where's this distribution network going to come from?

Might be they'll stop carrying a spare axle or two about to save a few quid on tax - did you factor that in?

 

[Munkul]

OK lets come at it another way.

14.6 billion miles travelled by HGVs in the UK last year. Let's convert them all to electric.
We'll go by a more optimistic (?) fuel economy value of 9mpg
That's approx 7.3 billion litres of diesel
73 billion KWh at 30% efficiency =21.9 billion KWh electrical energy to find from somewhere
divided into every hour of the year, this works out at 2500 GW extra demand on the electrical grid - MINIMUM. Not a problem if they built an extra thousand Hinkley point C's...



Calorific density needs to become the buzz word of the year. It explains perfectly why fossil fuels work so well for vehicles.
Sure, we need to change it, but it's not coming any time soon, not while we have a national grid on its knees already, and the energy density of lithium ion storage is pitiful compared to diesel.

Oh yeah

 

[daleyd]

I'm guessing this will apply to new vehicles sold, so there won't suddenly be the demand overnight, rather that over time as people change over it will go up - and I guess it might have a knock on effect of making the existing rolling stock last longer, if there is nothing suitable to replace it by then.

Though I can see the date slipping considerably unless there's some fairly dramatic leaps forward in technology in the near future - I'm guessing the current government are quite happy to make the pledge knowing it wont be them that has to finally deliver!

 

[octo0072000]

what about long haul running Europe /middle east no charging points in the desert

 

[AndersK]

I'll buy shares in uranium mining

 

[willie.macleod]

Start shifting move long distance stuff by rail/sea and use HGVs for shorter runs. Maybe take the opportunity to develop proper services with suitable charging facilities for recharging both vehicles and drivers.

 

[The Artilleryman]

Not in this country they won't. Joe public doesn't want large HGV's on the road, but want the goods they deliver.

Lol, and the jokers in Glasgow are volunteering to stop drilling new oil wells - even dafter, some kids are demanding it happens NOW. Better start digging the garden up for veggies then..
