2[Open]CAPTURE & PROCESSING

[Open]Carbon permanent storage is a proven solution that has been safe in operations for over 25 years

Sleipner CCS offshore of Norway is the world’s 1st geological storage
project for the purpose of carbon emission abatement. This project
captures carbon dioxide from gas development for storage in an offshore
sandstone reservoir.

Where is CO2 Being Stored?
CO2 is injected to deep geologicalreservoirs below impermeable rocks
Deep Underground
1 KeepCO underground at least 800
2meters below the seabed

Impermeable Seal
2 COis sealed in place by a thick impermeable
2layers of caprock

Permanent Storage
3 COtransform from gas into solid minerals
2Geological containment of CO2
The injected CO2 remain in Utsira sandstone for thousands of years,
similar to how O&G have been trapped in deep geological formations formillions of years.

Closely Monitored
4 UndergroundCO placement and movement is2

undergoing structured monitoring process

It is estimated that geologicalsequestration is safe withoverall leakage rates at<0.001% yr-1
(Alcalde et al. 2018).

[Open]PETRONAS has taken the approach of collaborative strategy in developing the CCS hub in which the partners are fromdiversified industries.
Development of CCS at Southern Hub will offer new future growth to Kuantan
Port

Development of 3-CCS hubs for Malaysia as a no-regret move to achieve this target and position
