There may be some applications which are harder to decarbonise than cars. Planes are also difficult. Some of the options which would be silly for cars (hydrogen, synfuels) may need to be used.
Good point. De-carbonising personal transport is an easier target (uber, shared, EV, public transport). But heavy goods, trade/industrial vehicles, long-distance, and cross-continent remain the elephant-in-the-room. Not an easy solution unless tax/carbon-offset becomes onerous and changes public behaviour.

Nice to have a civil discussion - how non-PH

A few outlier showcase examples.

Cant really see the local tree surgeon running a cable from the clients house to power his woodchipper, let alone a mile into the forest.

Running cables across construction sites a good idea? Will you have to install a fast charger before you can deliver your plant?

Meanwhile in the automobile world, recovery vehicles have started carrying these. Presumably because it's impractical to have flatbeds sitting in laybays.

Oh look, another moving of the goal posts by those in denial hehe

Woodchopper is what, 6-7hp? About 5kW. The benefit of an electric motor is it's more responsive to loading than a petrol, so it doesn't need to run all the time. So even at 5kW for an 8 hour day a 40kWh would suffice, which would be covered by something like a Rivian using it's external power supply. But chances are you'd use less power unless you're running a whole cutting team feeding the one chipper.

Clearly you have never worked in the industry.

A small commercial woodchipper is around 35hp. Bigger ones, well over a hundred.

Very dangerous machines, you absolutely can not have trailing wires anywhere near it.

Ignorance is bliss!

The new RAC breakdown vehicles use an uprated alternators off the main engine, and the AA are using battery packs.

you missed the point.

We will be using fossil fuel to rescue electric vehicles for a long time to come.

Don't get me wrong. I think plant is one of the few examples that could really benefit with electric power, generally for the noise and fumes.

But battery technology is still terrible and it's not practical/possible to run cables in 90% of circumstances, so fossil fuel they will remain for foreseeable future.

Best mate's a tree surgeon, he's switching his chainsaws to electric battery powered, reserving the dino-powered stuff for jobs that electric won't cut it. Main reasons being he's tired of the maintenance that goes along with fuel powered kit.

This will be the primary reason that industry switches to electric trucks. Tesla Semi is just, better.

Won't be long before battery capacity and power output is suitable to ditch combustion tools entirely. Gotta love exponential improvement curves eh?

Anyone considered plant?

DIgger's, bulldozers, wood chippers, dumpers, the list goes on and on.

Not practical to power them with electricity.
The genius is strong....

Even iff you take the 'saves 50,000te of diesel annually' with a pinch of salt.... its still rather good on the whole.

or Hybrid it up - but with HYDROGEN. https://www.popularmechanics.com/technology/infras...

Battery power is fine for small stuff/little jobs. If it saves wear/tear on the 2 stroke equipment than what's not to like?

Wow just reading that article, the AA attended 4000 EV breakdowns last year, for so few EV cars on the road that seems very high, I wonder if they included hybrids in that.

"Both the AA and the RAC acknowledge that with more electric vehicles on our roads, the likelihood of them running out of charge is increasing, so they’re working on ways to replenish their batteries. The AA says it attends around 3000 EV breakdowns a year, and this figure is rising rapidly. "

3000, not 4000?

I can't get a figure for how many breakdowns they attended in total, but they say they attend one every 9 seconds (that would be 3.5 million) and also that their 2700 mechanics each attend more than 1200 breakdowns a year (that would be 3.24 million). Taking the lower figure, 3000 would be 0.09% of their breakdowns. At the end of 2018, ULEVs amounted to 0.5% of all licensed vehicles. That 0.5% breaks down into 0.28% plug in hybrids, 0.175% pure electric cars, 0.025% range extended electric cars, 0.02% "other".

0.09% of callouts on 0.175% of cars doesn't sound entirely unlikely, given that there are some common callouts that don't depend on the power source (ran out of fuel/charge, flat tyre, locked self out, non-powertrain mechanical failure)

Yep 3000, fat fingers on the phone.

EV cars for me mean fully electric only, how many fully electric cars are on the UK roads at the moment?

I also agree it doesn't say the call outs are for drive train or battery-related problems, it just seems a high figure for what are brand new cars, most will be less than a year old.

Or quite likely 12V failures, and the odd flat traction because of Ecotricity appalling reliability at MSA.

Could be, the article could do with a bit more info TBH.
