Natural gas when sold as a transportation fuel, compressed natural gas or CNG, it is measured in gasoline gallon equivalent or gge.
What unit is gas measured in?
The LPG gas measurement unit for the measurement of gas volume, such as natural gas volume, is cubic metres (m³) or cubic feet (ft³) gas units. For gas measuement, 1 ft³ is equal to 0.0283168 m³.
LPG Gas Measurement Unit Chart.
|Gas Type||Attribute||LPG Gas Measurement Unit|
|Fuel Gases||Energy||megajoules (MJ), BTU or therms|
Is it cheaper to generate your own electricity with natural gas?
As illustrated, even when a range of electric prices are considered, natural gas prices are consistently two to three times lower than electric prices. In fact, when all charges are considered, for a $0.06 per kilowatt hour (kWh) electricity rate to be competitive, natural gas would have to cost $1.77 per therm.
How much CNG equals a gallon of gas?
Compressed natural gas
One GGE of natural gas is 126.67 cubic feet (3.587 m3) at standard conditions. This volume of natural gas has the same energy content as one US gallon of gasoline (based on lower heating values: 900 BTU/cu ft (9.3 kWh/m3) of natural gas and 115,000 BTU/US gal (8.9 kWh/l)).
How many BTUs are in a gallon of CNG?
How are GGE and DGE values determined?
|Fuel||Energy Content*||Quantity of Fuel in 1 DGE|
|Low Sulfur Diesel||128,488 Btu/gallon||1.00 gallon|
|Biodiesel (B20)||126,700 Btu/gallon||1.01 gallon|
|Biodiesel (B100)||119,550 Btu/gallon||1.07 gallon|
|Compressed Natural Gas (CNG)||923 Btu/cubic foot (ft3) or 20,160 Btu/lb||139.21 ft3 or 6.37 lb|
What is the price of natural gas per gallon?
Cost and Efficiency
At the time this article was written, the average cost of natural gas cost is $6.23 per 1,000 cubic feet, which is roughly one million BTUs. The U.S. average cost for propane is $2.41 per gallon. One million BTUs of natural gas is roughly 11.20 gallons of propane.
How do we measure gas?
The first thing to remember: natural gas is measured by volume (cubic feet) but is sold based on its heating content (Btus). A cubic foot of natural gas is the amount of natural gas that can be contained in a cube one foot on a side, at a certain standard temperature and pressure.
Why is gas measured in g l?
As you know, density is defined as the mass per unit volume of a substance. Since gases all occupy the same volume on a per mole basis, the density of a particular gas is dependent on its molar mass. Gas densities are typically reported in g/L. …
What is a unit of LPG gas?
LPG has a typical specific calorific value of 46.1 MJ/kg compared with 42.5 MJ/kg for fuel oil and 43.5 MJ/kg for premium grade petrol (gasoline). … The ratio between the volumes of the vaporized gas and the liquefied gas varies depending on composition, pressure, and temperature, but is typically around 250:1.
Is natural gas expensive to produce?
In fact, it’s not expensive at all! When compared to oil and propane, the two other common fuel sources in the United States, natural gas is more cost-effective than both—and not by a minor margin! … For example, while electricity is measured in kilowatts per hour (KWH), natural gas is commonly measured in therms.
What are the disadvantages of natural gas?
Disadvantages of Natural Gas
- Natural gas is a nonrenewable resource. As with other fossil energy sources (i.e. coal and oil) natural gas is a limited source of energy and will eventually run out. …
- Storage. …
- Natural Gas Emits Carbon Dioxide. …
- Natural gas can be difficult to harness.
What is the cheapest way to produce electricity?
The consensus of recent major global studies of generation costs is that wind and solar power are the lowest-cost sources of electricity available today.
