Why Tesla is building city-sized batteries

6 years 3 months 1 week ago

We talked to the co-founder of Tesla, JB Straubel, about why giant batteries are crucial to the future of power grids everywhere. Batteries are becoming more useful at powering bigger things like bikes, cars, and soon, entire cities. We explore some of the zanier forms of energy storage already in use around the country.

To do this on anything like the scale we'd need would be a monumental task and you'd have to replace all of it every 10 years. Next generation nuclear is the only way we can produce enough clean and reliable power to run civilised society.

Nice to finally hear pumped hydro mentioned when discussing energy storage.
Sure, it takes space, but it's non toxic, proven, doesn't bleed off like compressed air, and doesn't wear out every 10 years. Chemical batteries should be just for quick load shifts with hydro used for the majority of energy storage, imo.
