Storing solar energy indefinitely now possible thanks to carbon nanotubes | RobAid

By Damir B.

The idea of reversibly storing solar energy in chemical bonds is gaining a lot of attention these days. A group of researchers from MIT have developed a novel application of carbon nanotubes which shows potential as an effective approach to store solar energy for use whenever it’s needed. The method simplifies the process by combining energy harvesting and storage into a single step.

Previously, the chemicals used to achieve this type of conversion and storage either degraded within a few cycles, or included the element ruthenium, which is rare and expensive. Jeffrey Grossman, the Carl Richard Soderberg Associate Professor of Power Engineering at MIT, and postdoc Alexie Kolpak have created a new material which is a combination of carbon nanotubes and a compound called azobenzene.
