Comment on Norway on track to be first to go all-electric

  I’m not an engineer. I’m pointing out that the real world is proving that EVs can work just fine in the cold, so your assertion that they can’t doesn’t hold any water. This was a recent article of interest, though.

    Read over what you just wrote, and think about it for a second. If they have to be heated up to function, it supports my assertion that they do not function in extreme cold.

    That 12% is not insignificant, and that’s just for the piece to keep the battery at operating temperature. The battery’s capacity and performance will also be severely impacted on top of that, even with it warmed up. These inefficiencies and workarounds add up to the point that they eclipse the inefficiencies in hydrogen production, as the hydrogen is not impacted by any such issues at the point of use.

      The loss of efficiency in an ICE is roughly 15% in the cold as well.

      There are enormous materials issues with storing and transporting hydrogen that don’t scale well

        Why would they need to be scaled? Hydrogen is abundant in most corners of the globe. It can be farmed on site, as needed.

      They function at a 12% range loss. That is a far cry from ‘do not function’

      That 12% is not insignificant, and that’s just for the piece to keep the battery at operating temperature.

      No it’s not. It’s total range loss, not battery capacity reduction. The car gets 12% less total range, that’s the final figure taking everything else into account. You seem to have made up your mind about what you wish to support and are dismissing anything else that does not support your PoV.

        Then don’t heat up the battery, and see if it runs. Won’t work, because EV’s have to heat up the battery to get it working, because they don’t function in extreme cold.

        And while we’re at it, what’s the workaround for the batteries catching fire and exploding in the extreme heat of summer? We need to implement some cooling pumps while we’re at it?

        Or just skip all of the complexity, and use abundant & clean hydrogen.

  Secret sauce is Norway gets money the same place Saudi Arabia does: gas and oil. They have endless resource to whitewash themselves and seem green.
