| Thanks for sharing this info. One critical detail is missing. Context. Take the US case. 23.2 GW "capacity". Over what period of time? A second? A minute? An hour? A day? A month? A year? Let's take a case study of California, the "leader" in energy storage in the US. California removes reliable and cheap organic power plants, and is surprised to find at periods of peak demand when energy is needed most (heat waves, cold spells) the system falls apart. [By the way, removing reliable access to electricity is how you expose the most vulnerable segments of the population to danger of life and safety.] "The state’s grid operator blamed the blackouts on “a perfect storm” of extreme heat and unusually high demand, as well as a drought that’s limiting hydropower resources and a decline in electricity imports from neighboring states also struggling to keep air conditioners humming. Compounding the problem, 1 gigawatt of wind unexpectedly went offline Saturday, along with a gas plant.".... "“In some cases, we have built a reliability plan that isn’t completely realistic.”".... "The dearth of battery storage has long been a key barrier to transitioning to a green grid. Though the price of batteries has fallen significantly, they’re still not in widespread use. California only had enough to tackle about 1% of Monday’s peak load forecast, " California storage cannot handle 1% of battery needs. Please keep in mind when reviewing assumptions, claims, and statements about solar & wind grid. https://www.bloomberg.com/news/articles/2020-08-17/californi... |
