Bi-fuel ImpalaBiogas’ raw mixture of gases is derived from breakdown of organic materials stored in an oxygen-less environment. Methane gas produced is then processed to remove carbon dioxide and impurities for a Renewable Natural Gas (RNG), which in compressed form is a CNG replacement. Quasar uses waste from industries to make biogas. Ohio Renewable Energy Facility processes up to 25,000 wet tons of biosolids from City of Columbus Department of Public Utilities for wastewater.

Progressive Field makes available food waste for CNG-production once macerated in an industrial-sized InSinkErator Grind2Energy garbage disposal. Anheuser-Busch’s Columbus brewery provides an organic by-product too. Mel Kurtz, president of quasar energy group says buying renewable fuel at $1.95 per gallon reduces greenhouse gas emissions. Quasar’s Columbus facility can produce 1.3 mn gas gallons of CNG each year, adequate to refill 163,000 Bi-fuel Impala CNG tanks at least once.

California and Oklahoma have ample CNG fuelling stations but infrastructure in some states is sparse. Nichole Kraatz, Impala chief engineer fully understands the frustration of not finding CNG. Impala uses bi-fuel so customers can drive on CNG when available and on gasoline at other times.

CNG tank fitted in the trunk can store teh equivalent of 7.8 gallons of gasoline to traverse about 150 city miles of range based on GM testing. Combined fuel expected range is 500 city miles. EPA estimates are not yet available. Impala bi-fuel system switches to gasoline when CNG tank is empty. To ordinarily change fuels while driving, one simply needs to push a button. A light indicator on instrument panel specifies when CNG is in use. Bi-fuel Impala being factory-built is the lone sedan on the market to offer a factory warranty, covered by GM’s three-year/36,000-mile (whichever comes first) new vehicle limited bumper-to-bumper warranty and five-year/100,000-mile (whichever comes first) limited powertrain warranty.
