Natural Gas Vehicles (NGVs) are a viable alternative to gasoline and diesel-fueled vehicles. With current, available technology, NGVs can be fueled by Liquefied Natural Gas (LNG) or Compressed Natural Gas (CNG). Focusing solely on CNG for fleet applications, this paper provides insights and supporting information for CNG fleet vehicles.
CNG for Fleets
NGVs have existed as an alternative to petroleum since the early half of the 20th century. In the United States, transportation fuel has been dominated by petroleum products such as gasoline and diesel. While the U.S. has had access to petroleum for many years, recent global politics and affairs, emissions regulations and new developments in alternative fueling technology have renewed U.S. interest in new energy sources for transportation. According to the U.S. Energy Information Administration, U.S. NGV fuel consumption has steadily increased since 1998.
CNG is a feasible and cost-effective alternative for many application types, particularly fleet applications that consume high rates of fuel. As a leader in the natural gas industry, WGL develops targeted outreach and product offerings to support applications where CNG could serve fleet operations.
