Homework Statement
Brown coal, energy content 16 MJ/kg, carbon content 65% by weight, burning in a 30% efficient steam power plant.
Homework Equations
What is the emissions intensity (kg CO2 emitted/kWh delivered) ?
Compare this to Hazelwood which is 1.53 tCO2/Mwh
3. The Attempt at a Solution
I really have no idea how to do this question but this is what I tried
I have done a bit of research and worked out that 1kg of carbon = 3.67kg of CO2, so 0.65kg of carbon = 2.39kg of CO2. (1kg * 65%)
The energy produced is also 16MJ * 30% = 4.8MJ
4.8MJ = 1.3 Kwh
so the emissions intensity is 2.39/1.3 = 1.79 kgCO2/Kwh ?
