Summer to winter isn't a real storage case.
If you need more energy in the winter, you build more wind power, not PV to store it an entire year.
And episodes of little wind+sun have a duration of less than a month.
And there are more storage use cases, e.g. short term grid stabilization (<1 second).
- rocqua 3y agoYou cannot reasonably dimension wind power to serve the winter heating needs of northern Europe. Once you get halfway there you're summer surpluses get so huge, inefficient seasonal storage becomes a much better solution.
- tcfhgj 3y agoInterestingly, others worry that the seasonal phenomenon of wind power is too large: https://blogs.scientificamerican.com/plugged-in/wind-patterns-and-electricity-generation-vary-across-the-seasons/ https://blogs.scientificamerican.com/plugged-in/wind-pattern... Perhaps southern Europe will counteract as well: less need in the winter and energy required for increased cooling with heat pumps in the summer
