You do realize that it is winter in much of the inhabited world? Temperatures still drop below 0°C every night where I live and day length is still ways away from summer months. It is a great sign that we get negative electricity prices in these conditions quite regularly now. It means that we actually don't need nearly as much "seasonal" storage as many people seem to think. The capability to store for days and weeks is much more relevant than the capability to store for months.
