Moss Landing Power Plant: Nat Gas Fired 2.56 GW (1 M homes) Fuels more rich in H 2 are greener i.e., much less is CO 2 released NG: CH 4 +2O 2 CO 2 +2 H 2 O+ 890 (kJ/mol) Coal: CH +3/2 O 2 CO 2 +1/2 H 2 O+ 518 (kJ/mol) Why is natural gas is preferred ? air NG: CH 4 Oil: CH 2 Coal:CH Efficiency = 35 % combustion What do we do with all the CO 2 which is a greenhouse gas (GHG)?

Unformatted text preview: is not unlike nuclear waste storage. Costs are large, about 2-4 times current price of electricity. While US is proceeding, it is unlikely that China and India, the major sources of global CO 2 , will implement. Technology transfer is possible but high cost remains. Clean coal on the US scale and surely on the global scale is not likely in the near future (20 y).
