APPPENDIX
Orders of magnitude
• Energy-related CO 2 emissions per year
One passenger car: 5tCO 2
New York City: 50 MtCO 2
United Kingdom: 500 MtCO 2
US: 5 GtCO 2
World 30 GtCO 2
• What does a tonne of CO 2 represent?
CO 2 captured by 25 trees grown for 10 years
One return flight Paris to New York per passenger
The worldwide average CO 2 emissions per capita in 3.6
months
1.35MWh of electricity produced with supercritical
pulverized black coal power plant
• What is the cost of CO 2 emissions?
Source:
Carbon prices are generally below $20 /tCO 2
Market prices for EOR have reached $30 /tCO 2 with the
oil price at $100 /bbl.
Each tonne of CO 2 avoided by using CCS on a coal
power plant is likely to cost $53-$92 /tCO 2 .
Global average subsidy for solar PV in 2010 $530/tCO 2
relative to coal
Carbon emissions intensity of developed economies
ranges between $2,000 and $6,000 of gross domestic
product per tonne of CO 2 emitted

• Largest CCS integrated project in operation
ExxonMobil Shute Creek CCS-EOR project in North
America
Capture and store 6.5MtCO 2 /year
Equivalent to ~1 million passenger vehicles taken off
the roads
• Standard coal power plant (supercritical
pulverized black coal) without CCS
Nominal capacity: 500MW
Load factor: 0.9 in average
Produces 4,000GWh of electricity per year
Emits 3MtCO 2 /yr
• Standard coal power plant with postcombustion
CCS
Produces 3,200GWh per year (CCS energy penalty:
20%)
Captures 90% of CO 2 emissions
Avoids 2.6MtCO 2 /yr
• Ways of producing 3TWh a year of low-carbon
electricity
One CCS power unit in a single location (though with
extensive mining if powered by coal)
A 30km² PV farm with market-leading efficiency
A modern wind farm with 400 large turbines (2.5MW
each) spread over more than 100km² (equivalent to the
area of Paris)
