Get a pretty, enthusiastic hand waving girl to present stupid. She tries to make it believable that this is the answer. That energy storage system could power the grid for 30s at 3am (obviously it can’t discharge at that level, it’s just for an idea of scale). To power the grid for 1 hour, you would need 140 of them….or for 1 night of no wind and sun in the winter. 1,400 of them. this assumes a 100% discharge capacity and no grid losses, in reality probably 2000 would be needed. During the day our power consumption almost doubles.. So a non windy, rainy winter day would need 4000 of these batteries to provide power for 10 hours. More than 10 hours of rain, no sun and no wind…then the lights go out, even if we build 4000 of these things. Someone’s getting rich on the back of all this, because funnily, energy isn’t getting cheaper…quite the reverse,
We have one answer….conventional nuclear if we want long term energy security…especially when built with up to date tech.
