NATURAL GAS SUPPLY

America has an abundant domestic supply (90 + years) of conventional Natural Gas. In fact, the U.S. is the No. 1 producer of Natural Gas in the world.

What is natural gas?

What is natural gas?

Plentiful fuel source

Natural gas is a naturally-occurring, plentiful, odorless substance composed mainly of methane, a compound with one carbon atom and four hydrogen atoms. Natural gas also contains small amounts of hydrocarbon gas liquids and nonhydrocarbon gases. By comparison, gasoline has eight carbon atoms while diesel has sixteen. And unlike gasoline and diesel that are refined from crude petroleum – expending additional energy and creating added emissions – natural gas is not refined before its use as a clean transportation fuel.

Smart alternative

Because natural gas is abundant, cost-effective, and clean, it is a smart, low-emission alternative to traditional transportation fuels like gasoline and diesel. With an octane rating of approximately 130, natural gas allows for increased engine compression and combustion efficiency in vehicles and nonmobile sources in which it operates.

TYPES OF NATURAL GAS

Renewable is the cleanest option
Image is not available

Captured above ground

Renewable natural gas is biogas or biomethane that is captured as organic waste breaks down above the earth’s surface.

Recycled waste

An ultra-clean and ultra-low-carbon alternative, renewable natural gas is harnessed directly from decaying food waste, waste water, agricultural waste, and landfill gas.

Growing fuel source

In 2017, 24 percent of all-natural gas used in transportation was renewable natural gas. In 2018, that figure is expected to total between 31 and 38 percent.

Recoverable is the most abundant

Captured below ground

Recoverable – or geologic – natural gas come from large quantities of decaying organic materials that have accumulated over millions of years between layers of sediment beneath the earth’s surface.

Pressure cooked

Pressure from those surrounding layers of sediment and heat from the earth’s core convert this material into natural gas.

Readily available

North America has an abundant supply of this conventional natural gas, and recovery of this valuable resource occurs in 33 U.S. states. In fact, the United States is the No. 1 producer of natural gas in the world.

TYPES OF NATURAL GAS FUEL

CNG or LNG?
Compressed vs.
liquefied

CNG (Compressed Natural Gas) and LNG (Liquefied Natural Gas) are both captured from recoverable and renewable sources.  The difference is in the way they are stored and transported.

CNG (Compressed Natural Gas) and LNG (Liquefied Natural Gas) only differ in the way they are stored and transported.

CNG

Production – Compressed natural gas, or CNG, is natural gas stored and transported under high pressure in its gaseous form, making it lighter than air.  CNG is produced by compressing natural gas to less than 1 percent of its volume at standard atmospheric pressure.  CNG is safer than gasoline and diesel because it is nontoxic and disperses quickly. 

Transportation – After exiting the ground or extracted from a biodigester, natural gas is transported by pipeline or by virtual pipeline via tanker truck where it is compressed and stored at 3,600 pounds per square inch (PSI). 

Delivery – CNG is transferred from storage to a CNG vehicle through a fill nozzle and receptacle.

LNG

Production – Liquefied natural gas, or LNG, is natural gas stored and transported as a liquid.  After being sourced from the ground or from methane-producing waste products, LNG is produced by purifying natural gas and super-cooling it to -260 degrees Fahrenheit through a process called cryogenic liquefaction.

Transportation – LNG is transported via insulated truck, rail, or ship to LNG stations for distribution as a transportation fuel.  Because of its greater fuel density and lower weight storage, LNG is an ideal fuel for high horsepower and long-distance transportation needs since it requires fewer tanks and space requirements. 

Delivery – Like CNG, LNG can be dispensed through a fill nozzle and receptacle for on-road applications.

Transporting
natural gas fuel

By pipeline

Natural gas is delivered to U.S. customers through a 2.5 million-mile underground pipeline system. This natural gas can then be compressed or liquefied for use as a transportation fuel.

By virtual pipeline

For natural gas customers in areas where there is little or no infrastructure, CNG is transported via trailer in high-capacity, super-lightweight storage tanks. These trailers are filled at major gas pipelines then driven to end use sites for a continual, uninterrupted supply. CNG can also be transported via standard shipping containers and loaded onto a truck, train, or ship. After cooling to -260 degrees Fahrenheit, LNG can also be transported via virtual pipeline. Cryogenic insulation keeps LNG from boiling off overtime and allows for its tanker transport to end users via truck, train, or ship.
