Fleet Information


Fleet owners and operators across America rely on a wide variety of vehicles powered

by domestically produced natural gas that is both economical and clean-burning.

Natural gas vehicles (NGV) use proven, reliable technology to take advantage of our country’s abundant natural gas reserves.

The low cost of natural gas, combined with unprecedented public and private investment, has led to significant market growth and more vehicle and fueling options than before.

   The Basics of converting a fleet to CNG


 


 

 Economics


 NGVs enjoy significant economic advantages over comparable diesel and gasoline vehicles. NGVs have a higher initial cost due to the expense of specialized fuel systems and fuel tanks, but the low cost

of natural gas fuel relative to diesel and gasoline means there is a short payback period before realizing significant savings over the lifecycle of the vehicle.


 The positive economics of NGVs are here to stay. With the commercial development

of shale gas production, the price of domestic natural gas decoupled from the price of diesel. Independent studies now show NGVs capturing significant market share of both the light-duty and heavy-duty vehicle markets. The National Petroleum Council (NPC), under an “aggressive” scenario, predicts NGVs will capture 50% of the light-duty market, upwards of 35% of the Class 3 to 6 truck market, and almost 50% of the Class 7 to 8 truck (heavy-duty) market by 2050.

 

 The price for natural gas makes up a small portion of the price for CNG at the pump. A $1.50 increase in the cost of natural gas per million BTU translates to only a 25 cent increase per DGE (diesel gallon equivalent) at the pump. However, diesel prices spike because the raw commodity makes up a much larger portion of the price at the pump.

The fluctuations in the cost of oil can exceed the actual supply-demand picture due to international politics and the instability of foreign countries.


 CNG can be used in transit buses, semi-trucks, school buses, waste disposal trucks, and delivery vehicles. Currently, CNG fuels 1 of every 5 new transit buses in America. A CNG-powered school bus can displace 1,400 gallons of diesel fuel per year. Currently, there are more than 2,500 CNG buses in school districts across the country

CNG-powered vans and shuttles are already in use in major cities and airports, saving money on fuel and reducing emission levels. Since CNG is  a cleaner fuel, engine wear is reduced, allowing a vehicle to last longer. 



Environment


 Natural gas is the cleanest burning commercially available alternative fuel

today, and its use as a transportation fuel is improving the air quality and the health of communities across the country.

NGVs significantly reduce greenhouse gas (GHG) emissions and other smog producing emissions when compared to gasoline and diesel vehicles. According to the Argonne National Lab’s well-to-wheels emissions analysis that uses the latest

U.S. EPA figures, NGVs have the following emissions reductions over both new and in-use gasoline and diesel vehicles.

 

 Trucking companies find contracts are maintained or won based on their use of NGVs, or their willingness to implement NGV programs. This is because the use of NGVs satisfies the emission targets of many public and private fleets, as well as the green initiatives of many companies. Another benefit of NGVs is the simplicity of the fuel system in meeting EPA emission requirements. NGVs do not require any additional components or fuel additives.

Vehicles


Today, there are 142,000 NGVs on American roads. This number is steadily growing with the expanded availability of OEM (original equipment manufacturers) and SVM (small volume manufacturer) vehicle options. Below is the contemporary NGV count for light-duty, medium-duty, and heavy-duty vehicles, broken down by market.  

Light Duty Vehicles: 83,000


  Medium Duty Vehicles: 22,000-24,000
  • Cars, SUVs, trucks, and vans


 


Truck clear_small
 
  • 9,000 government fleets

  • 1,700 package delivery

  • 3,000 airport, university, and community shuttles

  • 9,000 utilities, F&B, commercial services, household goods, construction, misc.
 


Heavy Duty Vehicles: 33,000-35,000


   Transit Buses, Semi-trucks, & Refuse
  • 11,000 transit buses, shuttles

  • 5,300 school buses

  • 7,500+ refuse trucks

  • 5,000 port, regional haul trucks

  • 4,500–5,000 municipal, F&B, misc. vehicles

 Fleet vehicles of cities and major corporations

use CNG to save money on fuel costs and reduce emissions. With the same power as gasoline

or diesel fuel, CNG can be used in transit buses, semi-trucks, school buses, waste disposal trucks, and delivery vehicles.


 

 Currently, 1 of every 5 new transit buses in America is fueled by CNG. As more American businesses become aware of the many benefits of using natural gas in its transit fleets, this number will certainly improve. Cities such as Los Angeles,

New York City, Phoenix, Fort Worth, Dallas, San Francisco, San Diego, Denver, Atlanta, Washington, D.C., have natural gas transit bus fleets. Because they consume large volumes of fuel each year and emit large amounts of exhaust, transit buses are one of the best ways to save municipal fuel expenditures and improve city air quality.

 


Fueling


Fueling Choices

The economic and environmental benefits of using natural gas are there when using either form, but each form has unique advantages that make it a better fuel for specific applications. Natural gas fuel comes in two forms: CNG and LNG. 


CNG is made by compressing natural gas to 3,600 PSI, which is then stored in high-pressure cylinders. For short-haul and return-to-base operations, CNG is the better fuel choice.


LNG is produced by cooling natural gas to -260°F, which is then stored in insulated tanks. At this temperature, natural gas becomes a liquid and is 600 times more energy-dense than in its gaseous form. For many over-the-road (OTR) and other high-mileage trips, LNG is better.

Fueling Infrastructure

 Today there are more companies and organizations involved in the funding,

design, and construction of natural gas refueling stations than ever before. Some of the stakeholders engaging natural gas fueling infrastructure include natural gas retailers, “traditional” fuel retailers, LDCs, E&P companies, large fleets, and leasing companies. This increased activity has led to the development of over 1,300 public and private natural gas stations that now operate in the U.S. These stations are a mix of CNG fast-fill, CNG time-fill, LNG, and LNG/CNG stations that each have applications for which they are best suited.

CNG Fast-Fill and Time-Fill Stations


 CNG stations use natural gas delivered to the fueling site by the local gas utility’s underground distribution system and compressed to create CNG.


 Fast-fill stations use high-pressure cylinders to hold a large amount of fuel on-site that can then be quickly transferred to the vehicle to refuel in a matter of minutes. Fast-fill stations provide a traditional fueling experience and are developed for use by the public and fleet vehicles that need to refuel mid-shift.


 Time-fill stations compress the natural gas and distribute it directly to vehicles’ onboard storage cylinders. Time-fill stations are less expensive to construct than fast-fill stations and are best suited for return-to-base fleets that park overnight and can fuel at that time.
