The 2015 Bi-fuel Chevrolet Impala is capable of running on a renewable fuel called biogas, as a substitute for compressed natural gas, as well as gasoline. Much like when Doc Brown refuels the time-traveling DeLorean with a food scraps and beer, biogas is produced from food waste. Rather than opening the fuel cap and sticking in a banana peel, however, biogas is processed from the methane gas released by food waste.
Produced by Cleveland-based Quasar Energy Group, the resulting renewable natural gas is then compressed and is able to serve as a substitute for compressed natural gas. Quasar looks to a variety of industries for waste products to create fuel, including biosolids from the City of Columbus Department of Public Utilities, food scraps from Progressive Field, and by-products from Anheuser-Busch’s Columbus brewery.
