Advantages of CCS Disadvantages of CCS
Sequestration is
already used in the
oil and gas sector.
CCS may cut
35
in a
short time.
36
in
labour,
industry, and states
already support
CCS.
Alternatives, like
37
energy, take up vast
amounts of space.
The construction of new and the conversion of existing power plants
and the liquefaction and transport of CO2 are very costly. While
sequestration is possible, the scale would be enormous. Therefore, CCS
would need 38
.
Some CCS technology is 39
. Gas-driven
turbines for IGCC have not been used on an industrial scale.
Shallow underground storage may be limited; deep ocean storage is
currently impossible. Geologists fear leaks in quake-prone regions.
Natural gas and solar PVs are cheaper. LCOE estimates for
CCS = $0.09-15/kWh; for natural gas= 40
;
and, for solar PV = $0.0849/kWh.
