Whiskey waste or wattage?
Bourbon waste could provide next-gen supercapacitor components
From whiskey sludge to “car juice”? Fans cheer, skeptics cry hype
TLDR: Scientists in Kentucky turned bourbon waste into carbon for fast‑charging energy parts that could rival today’s tech, aiming to cut distillery costs and boost green storage. Commenters split between calling it hype and cheering trash‑to‑cash, with jokes flying while everyone waits for real‑world proof.
Kentucky’s bourbon by‑product—wet grain gunk called stillage—just got pitched as the next hot ingredient for fast‑charging power packs. University of Kentucky researchers say they can turn that soggy mess into carbon for supercapacitors (think lightning‑fast charge boosters) that rival today’s gear, even hinting at prototypes that store way more energy than usual. The science cameo happened at the American Chemical Society meeting, but the after‑party was in the comments.
The top vibe? Equal parts clapping and eye‑rolling. One joker deadpanned that “nobody is buying Bourbon and nobody is buying supercapacitors,” capturing a mood that this is a neat headline, light on reality. Another voice went harder, calling the whole thing “market manipulation with fake hopes,” suggesting this is just another lab‑bench miracle chasing subsidies and buzz. Meanwhile, optimists (quieter, but present) argue it’s a win‑win: distillers ditch a costly waste headache, and the grid or electric cars get cheaper, greener parts. Bonus: a distillery even offered the researcher 10,000 gallons of the stuff—talk about supply secured.
The thread also devolved into pun wars—“barrels of volts,” “aged to charge,” and “on the rocks, off the grid.” Between the memes and skepticism, one thing’s clear: people love the idea of trash‑to‑tech, but they’ve seen enough battery hype to demand proof outside the lab and beyond the press release.
Key Points
- •University of Kentucky researchers converted wet bourbon distillery waste (“stillage”) into carbon materials for energy-storage electrodes.
- •The conversion uses hydrothermal carbonization, leveraging the waste’s high water content to generate pressure and produce hydrochar.
- •Activated carbon was produced by treating hydrochar with potassium hydroxide at ~800 °C, yielding highly porous, high–surface-area material.
- •Supercapacitors made from these materials matched or exceeded the energy density of commercial devices; hybrid lithium-ion supercapacitors stored up to 25× more energy than conventional designs.
- •The work, presented at the ACS spring meeting in Atlanta, is a proof-of-concept that could help distilleries monetize waste and reduce disposal burdens.
