    Brydo, lol. As much as I think electric is good, it has its limitations as does everything. soon there will be mass campaigning to stop trying to get fossil fuels out the ground etc. Diesel was pushed to the masses and now it’s apparently less toxic than petrol so why is the diesel agenda still being pushed. Will the same happen with electric. Will Electric charging stations have back up generators for when there’s a power cut? I don’t have all the answers, tbh I don’t think I have any but I think hydrogen looks an interesting option going forward.

    Some of the charging stations already have back-up, some of the Tesla ones accumulate energy ready for when the demand on the chargers is greater than the connected grid capacity, possibly some of the others such as the new Gridserv EV stations as they want to generate lots of solar electricity from nearby and sell off the excess to the grid at peak times. There’s so much innovation going on with these things it’s hard to keep up. These developments are still in their infancy though.

    People are also putting in “powerwalls” to store their solar electric, and it’s possible to charge an EV from some of those, although capacities of powerwalls are currently very limited and a return on the investment is something like 13 years or more (longer than the lifetime of the batteries? an unknown). It’s been suggested that people store cheap Octopus Agile electric (when the price goes to zero or negative), but the wise on speakev have already worked out that it’s uneconomic to do so & it’s better to simply charge your car with that.

    Hydrogen is what I’d currently choose if I were living in the US & it was widely available, where people drive great distances, but in a few years time will Tesla have cracked the longer range batteries?

    As for answers, I think everything is unclear at the moment, I now drive an EV & there’s a balance between the limited range, the charging times, and the very low cost of electricity at home. I can currently go for a drive in the countryside down to the coast, have a walk along the beach (OK, wade through the pebbles in a wheelchair…), then pick some shopping up on the way home, arrive home & plug the car in for an overnight cheap charge…. possibly even get paid a few pennies to charge some nights…. so I’m relatively happy. This won’t suit everyone, it doesn’t suit me for those rare times I want to drive the 250 miles to see my parents, but it’s a couple of 1/2 hour charges to each leg of that journey (new multiple ultra rapid chargers going in at a BP station just after Thelwall viaduct off the M6/M62 will help there but the north is still grim for chargers).
