Topic: Lithium, cobalt, and rare earths

We continue our discussion of energy resources with a couple of minerals that will soon play an increasing role. We may soon begin exchanging lithium batteries as routinely as pumping gasoline. Lithium, cobalt, and the so-called rare earths are critical ingredients for batteries in cars, homes, and electronic devices, and they may soon begin to provide large capacity storage for utility companies that are increasingly depending on intermittent solar and wind energy sources. The demand for these resources is therefore anticipated to outgrow the demand for pretty much any other resources, over the short to near term future. And much of this is being mined from some of the poorest, most insecure places on Earth. Most of the demand for lithium and cobalt comes from manufacturers of batteries like those that power electronic devices and (increasingly) automobiles.

Rare earths have unique electromagnetic properties. There are several of them, but they are usually found in the same deposits, which are found at various locations, including the sea floor, which we’ll be looking at in a couple of weeks.
