Comparison of wood burial and power plant CCS. The markets use tCO2 as carbon unit which can be converted into tC with the conversion factor the molecular weight ratio CO2:C = 44:12; both units are shown.

Wood Burial
Power plant CO2 capture with geological storage
Price on Chicago Climate Exchange (CCX) 2006
European carbon trading market price during 2005–2007

$14/tCO2 ($7–27)
$20–270/tCO2 [14]
$3–4/tCO2
€1–33/tCO2
$50/tC ($25–100)
$73–990/tC
$12–16/tC
€4–120/tC
Storage safe; semi-permanent, reversible; some environmental concern
Possibility of leakage; lower cost storage capacity small


Potential: 10 ± 5 GtC y-1
Long-term: thousands of GtC or no practical limit
Potential rate is limited by scale of operation
Longterm: > 500 GtC
