How to address the storage issue with clean energy

Basically, transforming renewable energy sources into thermal energy and then storing it.

Then there is the business that is banking on rusting metal.

We refer to them as "iron-air batteries."

and they use chemical reactions in what they do.

that causes rust in order to store and release energy.

It's kind of lovely to me that something that we all tend to consider to be an annoyance may actually turn out to be very helpful.

These concepts are all currently in various phases of development.

However, they are drawing in investors.

and it is hoped that a few will succeed.

because not every power grid can accommodate one.

The grid will function as a type of patchwork solution, much like renewable energy in general.

Therefore, the more times we experiment with these solutions, the closer we come to determining exactly what combination will provide us with the grid of the future.
