Batteries and Energy Storage linked on Mimsy Were the Technocrats
Francis Turner has a slightly different take than I did on What will a useful electric car look like?. But he starts from a very similar observation, that most writers on battery-operated vehicles “are missing the point. We don’t want batteries, we want efficient energy storage.” And there is a mountainous difference between the energy storage needs of portable electronic devices and transportation devices, i.e., cars.
He also goes into something I only mentioned tangentially, which is that energy storage for evening out intermittent power sources such as wind and solar is so many orders of magnitude different than portable electronic devices that it’s crazy we’re even considering using the same storage technology to handle it. The money we’re spending on trying to shoehorn traditional batteries into storing grid-level power would be far more effective using other energy storage techniques—and unlike the energy storage needed for battery-powered vehicles, we already know what grid-level storage techniques can look like!
He also comes to the conclusion that, because gasoline is so comparatively useful at energy storage, the best “battery” for electric vehicles will be “synthetic hydrocarbons”, that is, man-made gasoline created from the energy generated by intermittent sources. I suspect that this overlooks how incredibly poorly-matched modern wind and solar technologies are to mass energy generation (in his defense he’s explicit about not discussing this), but when we do find a good means of generating mass intermittent power synthetic gasoline probably will be the best way to store it. As I wrote in a footnote to my post, “I wouldn’t be surprised if the eventual winning ‘battery’ technology ends up looking a lot like a synthetic gasoline.”
