The worlds production of storage isn't even sufficient to power germany for a week. Hence why germany is heavily dependent on gas. Mostly US liquified natural gas, and russian pipeline gas.
To me, it's a surprising statement that, for the same amount of money, one can buy something that doesn't exist. ๐ค
I am not arguing that nuclear should have been phased when it was, as that resulted in more coal and gas, but that clinging to it now is a mistake.
Building a new nuclear power plant in Germany would take a decade if things went well. Until then grid battery storage can mature and demand adjustment projects can be rolled out. It's probably also easier to convince germans to accept pumped hydro where they live over nuclear.
Sadly, others have argued so and still are. Here in Belgium the Green party is still trying to close existing, running nuclear power generation. In favour of building new subsidised "emergency" gas generation ๐
In my experience, people tend to severily under estimate the size of the storage problem. To power germany for a week it takes about 7TWh. There's around 0.1TWh of storage installed in the whole of Europe.
Why would we need to store energy for more than an day? We only need to smooth out the difference between supply and demand.
The mayor advantage of the European grid is the disconnectedness over long distances. There are always enough places where the sun shines or the wind blows.
I'd say the disconnectedness cross-border is a disadvantage as the grid already is saturated (1). It can be windy in poland, the generated power can't make it to france.
7 days is an understatement if going solar + wind + storage is the plan. Germany has longer periods of no sun and no wind on record.
