I think I linked to that one.

a buffer does seem vital for making a grid system work, big battery is better than standby coal or gas ticking over and waiting it also solves the pv nighttime issues as well as providing peak load for those busy times when load is greater than base capacity for a short while

https://reneweconomy.com.au/battery-storage-becomes-biggest-source-of-supply-in-evening-peak-in-one-of-worlds-biggest-grids/ The batteries stats are incredible. I have often run into Trolls claiming this is impossible and until now the only graphs I have seen show such invisible slithers of batteries that were hardly helpful. But now we see batteries as shifting an awful lot of evening load.

that's good news.

I wonder re

However, it noted, more than half of all electric buses are being delivered to London, despite the fact that the capital accounts for less than a sixth of the UK's bus market.

what the different challenges are for rural buses systems vs city

more distance less stops, sometimes, often not more distance as rural buses only run a few hours a day, rather than 2 or 3 shifts of driver and running for 20 hrs or more a day

it might be a while before bob's buses of ruralshire can replace their fleet with new ones, many rural buses are second, 3rd or more times pre loved

a while back some of the huddersfield area ones would have unroadworthy for peru

urban, such as tfl, manc, etc it seems a very good idea to replace older ice with new ev as the fleet ages

Again, sad they have to be sourced from China, but looks a sensible option for urban bus routes. Interesting also that they can be charged via a pantagraph; trolley buses used to be used in our local city but were phased out a very long time ago, 1950s or 60s I think. They could be useful for rural routes too, but as some round here must be well over 30 miles in each direction, they may take a while to penetrate. As you say Dpack, a lot of small operators have 2nd or 3rd hand buses. Judging by the variable livery of one of our local ones, the buses come from all over the place. Might be possible for the larger operators.

trolleys were ace tech, edwardian infrastructure was extensive, and can still be found, live, with a digger bucket

good batteries built into the structure of the vehicle are far more adaptable as to routes and uses

ps there was a trolley route in huddersfield that could challenge most contemporary ice, steam or donkey vehicles in a race to the top

more reliable in snow etc than the modern ice buses

trolley and tram(the public are the issue with trams, as the public are often careless of the huge thing lumbering slowly down the street) are both good in the right setting

if a bus route has a slowish straitish urban section with a good power supply, pantograph top up charging on the go seems ideal
big battery/fastish charge in a depot while it gets cleaned and maintained is practical and easier than pantograph infrastructure

We finally bit the bullet and bought an Ioniq 5. It's been fantastic so far, at least in terms of driving a small spaceship around rural New England.

I looked at that but too big for my needs, nice though.

Very nice, that one I'm keeping an eye on.

Meanwhile on my daily taxi run yesterday I saw 3 EVs in the space of a minute which is a record for me here.

Plus there's another story about heavy discounting in the UK, I see discounting as manufactures trying to keep the idea that EVs cost a lot more than ICE alive to keep their ICE sales going, whilst shifting EVs to more savvy buyers.

That just looks like a big car. Might be very suitable for you Slim, as your needs and conditions are completely different from ours. Be a good thing when those that feel the need for a SUV who don't really need one in the UK can be converted to electric. It will still clutter up the roads overmuch, but at least not throw out muck all over towns and cities. At present, no electric vehicles in our price range seem suitable for our needs, so we have gone hybrid for the car and have to stick to diesel for the trucks. Plus is that we are very low on mileage for all of them.

As Nicky has said previously thereâ€™s loads of drivers that drive far too much, that also needs to change. The Ioniq isnâ€™t an SUV but definitely bigger than I wanted

They officially classify it as an SUV, but like many of the "crossovers" it's kind of just a big 4 door hatchback.
If it wasn't for the kids and all the stuff we bring to and from visiting family two states away, I'd have gone for the Ioniq 6, and when my current two door hatchback finally throws in the towel due to rust, I would look for something similar to the 6, as who knows what the marketplace will look like by then (hoping for at least a few more years from my 14 year old car, could likely get to twenty depending upon the rust progression - that's what kills vehicles here)
