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). Refinery/Chemical Plant Bacterial Chemical Plant • Artemisinin C 15 H 18 O 4 MW = 262 g/mol • From plant Artemisia (wormwood) • An antimalarial agent • Normally produced from the plant artemisinin E.
