Electric car manufactures say that electric cars will have 10 times the already electricity capacity as they bring in the idea of batteries on wheels. Consumers worldwide are embracing electric vehicles, Gielen said. In Norway, half of all cars sold last year were electric, while China, the world’s largest market, is expected to reach 10% next year.
An introduction to smart charging for electric cars could also help tackle an huge issue with renewable energy, Gielen said – the massive storage capacity needed to keep grids going when the sun has set and the wind has stopped blowing. “You can look at these electric vehicles as batteries on wheels,” he said. “Ninety-five per cent of the time they are parked, and we need storage to integrate high shares of solar and wind into the grid, so why not use these batteries? The amount of car batteries, the gigawatts of car batteries, will be 10 times what we have compared to stationary batteries – that’s a lot of battery capacity.
“It doesn’t mean there is going to be no ownership at all, people can still choose to pay 10 times more, just like they choose to pay 10 times more for a watch,” he said. “That is all right, they are free – but most transportation will be autonomous, on–demand and electric.”
