Does burning natural gas produce CO2?
Natural gas is a fossil fuel, though the global warming emissions from its combustion are much lower than those from coal or oil. Natural gas emits 50 to 60 percent less carbon dioxide (CO2) when combusted in a new, efficient natural gas power plant compared with emissions from a typical new coal plant [1].
How much CO2 is produced per kg of natural gas?
One fuel is not like another – at least when it comes to carbon dioxide emissions. Burning lignite, for example, produces around twice as much carbon dioxide in relation to its energy content as burning natural gas….Specific Carbon Dioxide Emissions of Various Fuels.
| Fuel | Emission [kg CO2 / GJ] |
|---|---|
| Gasoline | 69,3 |
| Refinery gas | 66,7 |
| Liquid petroleum gas | 63,1 |
| Natural gas | 55,82 |
How much CO2 is in a ton of natural gas?
Carbon Dioxide Emissions Coefficients
| Pounds CO2 | Kilograms CO2 | |
|---|---|---|
| Carbon Dioxide (CO2) Factors | Per Unit of Volume or Mass | Per Million Btu |
| Kerosene | 21.78/gallon | 73.19 |
| Coal (All types) | 4,027.93/short ton | 95.74 |
| Natural Gas | 121.31/thousand cubic feet | 52.91 |
How do you calculate CO2 emissions for natural gas?
Carbon dioxide emissions per therm are determined by converting million British thermal units (mmbtu) to therms, then multiplying the carbon coefficient times the fraction oxidized times the ratio of the molecular weight of carbon dioxide to carbon (44/12). 0.1 mmbtu equals one therm (EIA 2018).
What is emitted when natural gas is burned?
The two main byproducts of natural gas combustion are carbon dioxide and water vapor, making it an extremely clean fuel when compared to coal and petroleum, which have higher carbon dioxide emissions, in addition to other harmful byproducts.
What is released when you burn natural gas?
When natural gas is burned properly, by-products of combustion are primarily carbon dioxide and water vapor. Because methane contains only one carbon atom, natural gas produces less carbon dioxide than any other fossil fuel, and fewer other pollutants as well.
How much CO2 does a natural gas power plant emit per year?
EPA’s Emissions and Generation Resource Integrated Database (eGRID), released in 2018 with 2016 data, shows that at the national level, natural gas units have an average emission rate of 898 pounds CO2 per megawatt-hour (MWh), while coal units have an emissions rate of 2,180 pounds CO2 per MWh.
