The above formula means that 16 g of Methane emits 44 g of CO2
Means 1 g of Methane produces 2.75 g of CO2
In a Combined Cycle power plant with 57% efficiency (AE64.3A in 3+1 Configuration)
- 1 M3 of Natural Gas Generates 5.7 KWh of Electrical Energy
- 1 M3 of Methane weigh about 760 g
Gas – Electricity Balance in a 500MW CCPP
In 100% of efficiency one cubic meter of Natural Gas generates 10KWh of electric Energy.
In a power plant (CCPP Class-F) with 60% of efficiency the generated electricity will be 6 KWh.
Then a 500MW CCPP – 60% efficiency needs 83,333 M3 per Hour of Natural Gas equal to 2,000,000 M3 per day at ISO condition (sea level and 15℃)
The demand should be 100,000 M3/Hour or 2,400,000 M3/Day.
