LEXINGTON, Ky. — Kentuckians drink a lot of bourbon, and that means a lot of fermented grain leftover after distillation. For every bottle of bourbon produced, there’s up to 10 barrels of waste, in the form of stillage.
That’s what drove University of Kentucky researchers to develop a way to transform this waste into high-performance components for supercapacitors. This solution repurposes an industrial byproduct in a way that could eventually help stabilize the electrical grid.
