INTRODUCTION
Increasing concentration of CO2
Contributing to Earth’s global warming
CO2 is emitted when fuel is burnt
in large power plants
Currentl!" #$ %t per !ear of CO2 is emitted

WHAT IS CCS?
effecti&el! capturing" compressing
"transporting"
and permanentl! in'ecting and storing in
geologic formations of carbon dio(ide )CO2*
from industrial or power plants

NEED OF CCS
+an! countries are hea&il! dependent on fossil
fuels for energ! generation
With an a&erage of two coal,fired power stations a
week being built in the de&eloping world
-he climate is changing and the prime cause is
humanit!’s use of fossil fuels

WORKING OF CCS
CC. is essentiall! a group of technologies for/
0Capturing CO2 from industrial
sources or power plants1
2Compressing and transporting it1

formations underground

CO2 CAPTURE
0CRO%ENIC 3R4C-ION4-ION
.eparation of gases through cooling until the! enter
their li5uid states
6ue to different 7eats of 8apori9ation" a li5uid:gas
mi(ture can then be separated

CO STORAGE
0%EO=O%IC4= .-OR4%E
+ethod in&ol&es in'ecting
carbon dio(ide" directl! into
underground geological formations
The most promising sequestration sites
.torage capacit! of at least 2$$$ %t CO2

.OCEAN STORAGE
6irect release into the oceans1
large capacit! to absorb and store CO2
Can harm marine organisms near
the injection pointwould gradually affect the whole
ocean
Generally no longer considered as anacceptable option

CONC)USION
=arge reductions in emissions of CO2 to the
atmosphere are likel! to be needed to a&oid ma'or
climate change Capture and storage of CO2"in
combination with other CO2 abatement techni5ues"could
enable these large reductions to be achie&ed
with least impact on the global energ! infrastructure
and the econom!
