Ranking Renewable and Fossil Fuels on Global Warming Potential Using Respiratory Quotient Concept

Figure 1

Estimated variation of HHV with fuel composition using Boie equation. HHV decreases with increase in oxygen content in the fuel. Multiply HHV in kJ/kg by 0.43 to obtain BTU/lb. H/C: hydrogen to carbon atom ratio and O/C: oxygen to carbon atom ratio.
