It is not all perfect, salt (molten) batteries have an operating range of about 300 degrees. In addition to having very long preparation times after discharge. If you don't use them in daily use they tend to discharge over time. And they have very low energy densities.

We can wait for some scientific advances, but it is whishful thinking to hope that in a few decades they will invent the ultimate solution.

Hydroelectric plants are the only large-scale storage, but they are highly dependent on the geology of the country.

They are not a solution to seasonal storage.

For me it is useless to go on all these big trips, the solution is very simple: mix of nuclear for base load, and renewable for peak.

Hydroelectric plants are not, in fact, "the only large-scale storage". Numerous practical storage methods are being fielded, many suitable at any scale.

Pumped hydro is not, in fact, "highly dependent on the geology of the country". It needs a hill. Hills are very common.

A "solution to seasonal storage" is not, in fact, needed or useful. NG backup works and will continue working into the indefinite future.

Anyone obliged to invent falsehoods to make their case reveals they have no case. No one has ever suggested we "destroy whole landscapes" for solar. You made that up from whole cloth.

Good day.
