However, certain materials used in these devices can be costly and pose environmental concerns. Creating energy storage solutions from commonly discarded items could solve these issues.
Researchers claim that excess energy needs to be stored somewhere so that the world can eventually profit from its production. For instance, an excess rooftop solar panel supply has recently caused California negative energy costs on bright days. Electron microscopy revealed the presence of carbon-based nanostructures, or CNOs, in the soot. These CNOs resembled layers of onions and were uniformly spherical lattices of concentric graphite rings.
