The storms' sand grains and other particles create electric charge in what is known as the triboelectric effect, which happens when two objects repeatedly collide with or rub against one another.

Toward Large-Scale Energy Harvesting by a Nanoparticle ...

This article describes a simple, cost-effective, and scalable approach to fabricate a triboelectric nanogenerator (NG) with ultrahigh electric output. Triggered by commonly available ambient mechanical energy such as human footfalls, a NG with size smaller than a human palm can generate maximum short-circuit current of 2 mA, delivering instantaneous power output of 1.2 W to external load.

Triboelectric effect - Wikipedia

The triboelectric effect (also known as triboelectric charging) is a type of contact electrification on which certain materials become electrically charged after they are separated from a different material with which they were in contact. Rubbing the two materials each with the other increases the contact between their surfaces, and hence the triboelectric effect.
