Combustion Fuels - Carbon Dioxide Emission

Environmental emission of carbon dioxide CO2 when combustion fuels like coal, oil, natural gas, LPG and bio energy

To calculate the CO2 emission from a fuel the carbon content of the fuel must be multiplied with the ratio of molecular weight CO2 (44) to the molecular weight Carbon 12 -> 44 / 12 = 3.7

Carbon Dioxide emission can be calculated as

qCO2 = cf / hf  CCO2/Cm         (1)

where

qCO2 = specific CO2 emission (CO2/kWh)

cf = specific carbon content in the fuel (kgC/kgfuel)

hf = specific energy content (kWh/kgfuel)

Cm = specific mass Carbon (kg/mol Carbon)

CCO2 = specific  mass Carbon Dioxide (kg/mol CO2)

Emission of Carbon Dioxide - CO2 - when combustion some common fuels are indicated in the table below.

Fuel Specific Carbon Content
(kgC / kgfuel)
Specific Energy Content
(kWh / kgfuel)
Specific CO2 Emission
(kgCO2 / kWh)
Coal (bituminous/anthracite) 0.75 7.5 0.37
Gasoline 0.9 12.5 0.27
Light Oil 0.7 11.7 0.26
Diesel 0.86 11.8 0.24
LPG - Liquid Petroleum Gas 0.82 12.3 0.24
Natural Gas, Methane 0.75 12 0.23
Crude Oil     0.26
Kerosene     0.26
Wood 1)     0.39
Peat 1)     0.38
Lignite     0.36
Bio energy 0 - 02)

1) Commonly viewed as a Bio fuel

2) Bio Energy is produced from biomass derived from any renewable organic plant, including

Emissions of CO2 can contribute to climate change. Combustion of bio energy don't add to the total emission of carbon dioxide as long as the burned bio mass don't exceed the renewed production. (Emission of CO2 when combusting wood is in reality approximately 0.18 kg/kWh)

A variety of bio fuels can be made from biomass resources, including
