Base/peak wind imbalance not a problem in Coachella Valley, they were using off peak wind to make hydrogen from water, storing it as hydrogen gas, and mixing it with natural gas, and burning it (at IIRC and 80/20 ratio) in peaker plants, since back in the early 2000's. Hydrogen electrically separated from water is usually considered "expensive", unlesss you're using essentially "free" off peak wind to generate the power.

The ultimate solution will be a fully distributed grid, with down to in-home storage (and back up for emergencies)from low impact high capacity battery technologies. This allows you to recharge with daylight solar and store it for night uses. This also applies to electric vehicle recharging, where night off peak recharging, can utilize power from things like off peak wind power The rest of the world is taking the coming loss of half of the Everglades and a good part of Southwest Florida, from sea level rise, in the next 60 or so years, more seriously than we are, so they testing more strange stuff like this...

I support some of the much safer and more efficient nuclear technologies that could replace the costly and more dangerous water cooled reactors. Once again, pseudo science spouting fear mongering, some based on real problems, but much based on a general appeal to public fear and ignorance, seems to dictate our choices in some of these things. Meanwhile, the planet is getting significantly hotter, and sea levels are rising (things we can and do actually measure independently,done by thousands of folks, every day, all over the world....as part of the "vast conspiracy" to collect weather data?)...

Now, if we can only use some of those greenhouse gas fees to electrify LOSSAN, and build a "higher speed" line that could easily take 75,000 or more trips a day off of the gridlocked I-5 corridor? Then, maybe we could capture that dynamic braking and feed it back into the grid, someday, too...
