2015 Chevy Impala to Run on Biogas

By  | 

Chevrolet has announced that they are set to include biogas tanks as an option on their existing 2014 Impala model. Two versions will be available: the base LS and the upper-tier LT.

Though they haven’t released any official details on either models, the base LS version is set to be “almost exactly the same” as the existing LS model.

In 2015, the Impala will have the option of a 7.8 gallon carbon neutral gas tank. Chevy say that the tank will last approximately 150 city miles at 19 mpg, and in order to avoid any problems with availability of CNG, the Impala will also have a standard gas tank which takes the overall mileage up to 500 providing both tanks are full.

The biogas itself is the product of broken down organic materials in anaerobic conditions. The gasses produced during this processes are mainly methane and carbon dioxide which are then further processed to create the CNG.

Plants such as the Cleveland-based Quasar take up to 25,000 wet tonnes of biosolids of wastewater from the Department of Public Utilities and Cleveland’s Anheuser-Busch’s Columbus brewery also provides a bi-product for Quasar to use in order to create CNG.

Usable waste includes sewage, plant material and other green wastes, meaning that this renewable resource is in plenty of supply and will also save valuable landfill space. Not only is CNG much better on the environment, it also has other implications that could be used instead of draining the slowly but surely depleting oil sources.

In the UK, it is estimated that 17% of all gas fueled vehicles could be run on CNG, and this is only as it stands currently, with further research and funding likely to increase that figure. This renewable energy source is surely a great way in not only helping the earth, but our wallets too. With a price of around $2 per gallon, it’s over a third cheaper than standard gas, and as we all know, gas prices are only going to rise in the future.

As for the Chevy Impala’s pricing, prices are set to start around $39,000 before taxes and extensions are considered. However, critics may question the $10,000 increase for the CNG tank when compared to the standard Impala — converting a car or truck to an (albeit smaller) after-market system in comparison to the Impala would cost much less, around $1,500 for the system and installation.
