One GGE of CNG pressurized at 2,400 psi (17 MPa) is 0.77 cubic feet (22 litres; 5.8 US gallons). This volume of CNG at 2,400 psi has the same energy content as one US gallon of gasoline (based on lower heating values: 148,144 BTU/cu ft (1,533.25 kWh/m 3 ) of CNG and 114,000 BTU/US gal (8.8 kWh/L) of gasoline.

The MPGe metric was introduced in November 2010 by EPA in the Monroney sticker of the Nissan Leaf electric car and the Chevrolet Volt plug-in hybrid. The ratings are based on EPA's formula, in which 33.7 kWh (121 MJ) of electricity is equivalent to one (U.S.) gallon of gasoline, [ 8 ] and the energy consumption of each vehicle during EPA's five ...
This regulation defines a standard cubic foot, for compressed or liquefied gases in refillable cylinders other than LPG by, "A standard cubic foot of gas is defined as a cubic foot at a temperature of 21 °C (70 °F) and a pressure of 101.325 kilopascals [kPa] (14.696 psia)".
CNG must be stored in high-pressure cylinders (21,000 to 25,000 kPa (3,000 to 3,600 psi)), and LNG must be stored in cryogenic cylinders (−162 to −129 °C (−260 to −200 °F)). These cylinders take up more space than gasoline or diesel tanks that can be molded in intricate shapes to store more fuel and use less on-vehicle space.
In 2013, Nat G CNG Solutions and AGA Systems announced that it had begun offering a Compressed Natural Gas (CNG) version of the Chevrolet Equinox and the GMC Terrain using the 2.4-liter direct-injected engine. The natural gas version is a "bi-fuel" CNG vehicle, meaning that it can run on either gasoline or natural gas, giving it extended range.
3M Announces Certification for CNG Tank Tank is lighter and more cost effective for fleet vehicles ST. PAUL, Minn.--(BUSINESS WIRE)-- 3M (NYS: MMM) announces it has successfully completed the NGV2 ...
The metric ton is the name used for the tonne (1000 kg, 2 204.622 62 lb), which is about 1.6% less than the long ton. The US customary system also includes the kip , equivalent to 1,000 pounds of force, which is also occasionally used as a unit of weight of 1,000 pounds (usually in engineering contexts).
The Brazilian Fiat Siena Tetrafuel 1.4 is the first bi-fuel car that runs on natural gas (CNG) alternating automatically with any of the typical fuel blends used in flexible-fuel vehicles, pure gasoline, or gasohol E25, or just ethanol . Shown below are the CNG storage tanks in the trunk.
