The point is, why do you store energy at all. It's not because you'll need it later. It's because you can sell it later. If there's no way to monetize excess energy (because we lack storage), people won't invest into making excess energy. And since renewables produce a lot of excess energy it makes them less desirable than they should be. Analogy to broken window fallacy is totally warranted. But please notice that w…
It's not because you'll need it later. It's because you can sell it later. This gets the cause and effect completely wrong. The only reason you can sell it later is because someone will need it later. As a society you store energy precisely because you will need it later. Whether you do this by creating a market for it or not is purely an implementation detail.
If you have no way of selling it it doesn't matter how much it is needed.
So you will set up energy storage company only if you know you'll be able to sell energy you store later at high enough price.
Form the point of view of the economy it doesn't matter what will happen to energy. And economy is not just direct effect of physical causes. It's separate system that to some degree is synced with physical world. But not all that much. Much of our wealth is locked up into capital that is being gambled to get more capital without any connection to physical world. And when those connections occasionally crop up it might even be dangerous like in the case of global food prices recently when investors figured out a new game using food prices for them to gamble. You probably think that crypto is one such dangerous connection, but I believe it might be a beneficial one.
Crypto is not an electrical battery. It's economical battery. It turns energy, potentially any amount of it, into value. Even the worthless energy, that is produced when conditions are excessively good for energy production.
The beneficial effect of crypto is that it is variable load that can turn any amount of nearly worthless localized energy into globally transferable value.
You can use the value later to purchase energy (and energy generation equipment) anywhere else.
As such it incentivises building energy sources that might generate a lot of excess energy on peak production, like windmills or solar panels, or that are too remote to transfer their excess energy to places where it could be utilized.
