I read somewhere that an EV truck charging station would have a similar energy demand to a small town. The charging times makes trucks and in particular plant machinery much more costly as their down time increases.
This is not progress.

Hydrogen is the answer. People will eventually see sense.

Hydrogen for artics and long haul seems to be most logical, however I would like to understand the efficiency differences between producing hydrogen and e-fuels.
Both are nowhere near as efficient as just putting the electricity in a battery (rather than powering the industrial process to create hydrogen or synthetic fuel), but there would be no significant infrastructure changes to support e fuels.
Another consideration is the additional difficulty in storing hydrogen and the fact it can get a bit “ bangy “ if you aren’t careful with it. Can you imagine the consequences of a motorway crash involving a hydrogen powered artic if it went up ?

The charging times makes trucks and in particular plant machinery much more costly as their down time increases. This is not progress. This is a problem given that our increasingly online world has led to a massive surge in data centres cropping up which are sucking so much power from the National Grid that in some areas of West London house building has had to be restricted because the Grid has no more capacity to provide them with power. Add in yet more EV and electric truck charging stations to the mix and there's going to be a real shortfall. |

I mooted this event some time ago but was talked down with "We have more than enough"etc etc.
Seems we don't and will not for a while to come........

Every time I point out in various forums that cities like London and Paris will never be able to cope with charging requirements of replacing all their traffic I get abuse and told : the capacity is there.... It may well be "there" but "there" is a power station 250km away feeding the city through a cabled network with ever diminishing cable cross section areas as it is delivered to the end point. Lots of people don't understand electricity and think it's like Jack's magic beans and can suddenly deliver 60A through a 13A appliance cable without catching fire. (60A is the largest single phase allowed). As Martin points put, the costs and work associated with providing large scale charging nationwide is UNBELIVEABLE and as I said earlier, there's absolutely zero incentive for the electricity producers to spend that money as they can sell all they can make as it is. When I was at that Westminster forum event recently, the two most blase and utterly out of touch people there, were the civil servant lady who is the head of UK decarbonisation, and the guy from the national grid, who claimed - as per BB's comments - there is no problem with capacity. There is not so much an issue with generation - its the local infrastructure that is clearly a massive issue. We know from our fleet clients that if you want power sufficient for a bunch of high speed commercial EV chargers, you will be given a lead time of years. Hence I have set up partnerships with companies that can supply solar and battery backup and so on so you can generate and store locally! And I read recently that car park solar power generation (which seems a very logical place to put them) is taking off in the UK but hugely hampered by lead times of years to get the power back into the grid! Then again you have places like Oxford (whose city council use our Telematics to know state of charge/battery level/range when vehicles are out and about) who seem to have managed to put chargers all over the place, enough for people not to need one at home, the result being >50% of the cars newly registered there are BEV. |

It wouldn't surprise me if the two out of touch people were just spouting what they have been told to say. I am sure there are more than a few in Government who know the truth but for some reason, it is Government policy to keep the public fed with nonsense so that we all gravitate to EV's voluntarily. |
