“The fuel tank has been the most expensive single component on a CNG vehicle, causing a bottleneck for the market,” said Nathan Pumphrey, Chesapeake Director – Fleet Operations. “3M’s tank portfolio will lower the total cost of natural gas vehicle ownership and speed market adoption. We look forward to incorporating these tanks into our fleet vehicles to save money on our conversions; and with CNG available for as little as $0.99 per gasoline gallon equivalent in some markets, we’ll cut our fueling costs, too.”In line with a broader commitment to CNG, 3M has also begun working with its transportation providers to utilize CNG on trucks carrying 3M products. 3M has already implemented a pilot program with Dart Transit Company on dedicated routes, and anticipates others will follow. Because fueling with CNG reduces greenhouse gas emissions and particulate matter, the move to natural gas-powered vehicles continues 3M’s commitment to sustainability.
