Alnuaim Energy Decarbonization Roadmap
4- Decarbonization thru Carbon Capture & Storage
Existing & Planned CO2 Storage and EOR Projects
CCS facilities under development has grown 44% year on year to 244 million
tonnes per annum in the past 12 months, with 61 new facilities added to the project
pipeline in 2022, growing to 132 facilities by 2030.

Why CO2 is Bad for Environment?
CO2
emission
modelling which is
under
scientific
debates.
CO2
and
other
greenhouse
gases
act like a blanket or
a cap, trapping some
of the heat that
Earth might have
otherwise radiated
out into space.

Why CO2 is Bad for Environment?
When sunlight reaches Earth, the surface absorbs
some of the light’s energy and reradiates it as
infrared waves, which we feel as heat. These
infrared waves travel up into the atmosphere and
will escape back into space if unimpeded.
Simplified diagram showing how Earth transforms
sunlight into infrared energy. Greenhouse gases like
carbon dioxide and methane absorb the infrared
energy, re-emitting some of it back toward Earth
and some of it out into space.

Can we capture CO2 from Air?
10
Example: Direct CO2 Air Capture (DAC)
Direct Air Capture
(DAC) is a technology
that removes carbon
dioxide (CO2) from the
atmosphere.
Using
high-powered
fans, air is drawn into a
processing
facility
where the CO2 is
separated through a
series
of
chemical
reactions.
This is more expensive. Why?
