Storage emits a lot more co2/kwh though, and that's a big problem. Even when you remove cost from the equation.
There's also no grid in the world that runs on wind/solar+storage, it's obvious from looking at California that it would take 20+ years to arrive there.
- pfdietz 4y agoStorage needn't emit any CO2 at all. In a world that has transitioned entirely to non-fossil energy sources, where are you thinking this CO2 is coming from? Cement production? Batteries aren't made of cement.
- ncmncm 4y agoStorage emits CO2... Really, you think so? Before you have built a thing, you have to build it. After you build it, you have it. Building will be a big job, but nowhere near as big as building nukes instead would have been. The good news is that renewables start displacing CO2 emission almost immediately after ground is broken. It would be stupid to build storage without renewable capacity to charge it from. You spend on that first.
