Kentucky produces an astounding 95% of the world’s bourbon whiskey, a process that generates substantial amounts of stillage—spent grains left after distillation. The volume of this byproduct is staggering; for every barrel of bourbon made, six to ten barrels of stillage remain. Traditionally, this sticky, water-rich waste has been sold as livestock feed or soil fertilizer. However, the challenges of transportation and drying costs have long posed logistical and economic hurdles for distilleries aiming to manage this biomass.

Enter hydrothermal carbonization (HTC), a technique analogous to pressure cooking that converts wet biomass directly into carbon-rich materials. By applying this high-pressure, high-temperature process to stillage, the research team transformed this unwieldy waste into a dry, fine, black carbon powder. This is a critical step, as carbon-based materials are fundamental components in fabricating electrodes for supercapacitors—a class of devices known for rapid energy storage and release.

The conversion process involved subjecting the stillage to HTC in a reactor capable of handling large volumes, ensuring scalability beyond laboratory trials. Following this, the carbon powder was further processed through pyrolysis, heating it to temperatures around 200 degrees Celsius to produce hard carbon. Alternatively, a higher temperature treatment at 800 degrees Celsius with potassium hydroxide (KOH) activation produced activated carbon known for its highly porous structure. These two distinct carbon forms offer complementary electrochemical properties suitable for different supercapacitor designs.

Hard carbon exhibits a disordered layered structure that facilitates lithium-ion intercalation, essential for lithium-ion hybrid supercapacitors. Activated carbon, with its extensive internal surface area due to its porous nature, excels in electric double-layer capacitors (EDLCs). These characteristics make the stillage-derived carbons uniquely suited for developing next-generation energy storage devices that combine high energy density with rapid charge-discharge cycles.

For proof-of-concept, the team constructed coin-sized supercapacitor cells by sandwiching liquid electrolytes between pairs of activated carbon electrodes. Remarkably, these devices demonstrated energy storage capabilities on par with commercial supercapacitors, reaching up to 48 watt-hours per kilogram. This performance metric places the stillage-derived materials as competitive alternatives in the energy storage market, with the added benefit of valorizing industrial waste.

Taking innovation further, the researchers engineered hybrid lithium-ion supercapacitors by pairing a lithium-ion infused hard carbon electrode with an activated carbon electrode. These hybrid devices marry the high power density and durability of capacitors with the superior energy storage of lithium-ion batteries. The stillage-derived hybrid supercapacitors exhibited energy densities up to 25 times greater than conventional counterparts, marking a substantial leap in sustainable energy technology.

Beyond just material development, this research underscores a novel circular economy model where an agricultural byproduct is repurposed for advanced technological applications. The interdisciplinary team collaborated extensively with distillery owners across Kentucky, Illinois, and Canada, ensuring a steady supply of raw material while fostering industry-academic synergies that could facilitate real-world implementation.

Comprehensive physicochemical characterization confirmed the suitability of these carbons for energy storage applications. Techniques such as Raman and Fourier-transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), thermogravimetric analysis (TGA), scanning electron microscopy (SEM) coupled with energy-dispersive X-ray spectroscopy (EDS), and nitrogen physisorption elucidated the structural and chemical properties critical for electrochemical performance.

Electrochemical testing involved cyclic voltammetry, galvanostatic charge-discharge profiling, and electrochemical impedance spectroscopy, providing in-depth insights into charge storage mechanisms and device efficiency. The activated carbon electrodes exhibited excellent stability, retaining 96% of their capacitance over 15,000 charge-discharge cycles, a testament to their durability and potential longevity in practical applications.

Looking ahead, the research team plans to delve deeper into optimizing the energy storage mechanisms, scaling up device dimensions, and refining electrode fabrication techniques. Such advancements could pave the way for integrating these supercapacitors into electrical grids, particularly to stabilize fluctuating inputs as renewable energy sources become increasingly prevalent.

Economic and life cycle assessments are underway to evaluate the commercial viability and environmental impact of deploying this technology at industrial scales. Early findings suggest that transforming bourbon stillage into high-performance energy storage materials could reduce waste management costs for distilleries while contributing to greener, more sustainable battery and capacitor production.

This innovative project not only addresses a pressing problem at the state level but also signals a wider paradigm shift in how agricultural waste streams are valorized. Collaborations with international partners, including the Friedrich Schiller University Jena in Germany, highlight the global relevance of such sustainable technological solutions.

Funded by the U.S. National Science Foundation and the University of Kentucky, this work was presented at the spring 2026 meeting of the American Chemical Society (ACS), drawing attention from a broad audience of chemists, materials scientists, and energy engineers. The compelling fusion of waste valorization and cutting-edge energy storage underscores the transformative potential of chemistry to enable sustainable advances.
