Whisky Biofuel May Soon Be Available At Scotland Pumps
Whisky may soon be allowed into cars, not as a beverage, but as a whisky biofuel. Researchers at the Edinburgh Napier University in Scotland recently requested a patent for a process that they have developed that converts waste from whisky production into whisky biofuel.
Whisky production is a 4 billion pound industry in Scotland, making byproducts of the process plentiful. The new whisky biofuel is made from a combination of the liquid that comes from the copper stills, which is known as "pot ale", and the spent grains, which are known as "draff."
To create whisky biofuel, the team started with a 100 year-old process that was originally used for generating butanol and acetone from fermented sugar cane. They altered this process to suit the byproducts of whisky, and still achieved butanol as the end result. Butanol is a biofuel that produces 30% more energy than traditional ethanol biofuel currently available at gas pumps.
Vehicles and airplanes can run on whisky biofuel with no adaptations to their engines. The research team is already planning to create a company to commercialize this development, and hopes to eventually see whisky biofuel sold at gas stations in Scotland alongside regular gasoline.
