Kasawari CCS project

The Kasawari Carbon Capture and Storage (CCS) Project is a major offshore carbon sequestration initiative being developed by PETRONAS Carigali in Block SK316 offshore Sarawak, Malaysia, approximately 200 km from Bintulu in the South China Sea. As part of the broader Kasawari gas field development, the project will capture CO₂ associated with natural gas production (notably flaring emissions) and permanently store it in a depleted reservoir (the M1 field) via a ~138 km subsea pipeline connecting the new CCS platform to the storage site. A dedicated offshore CCS platform—designed and built under an EPCIC contract awarded to Malaysia Marine and Heavy Engineering (MMHE)—will host CO₂ processing and compression equipment to separate and transport CO₂ for reinjection. The Kasawari CCS facility is planned to begin operations in the latter half of the 2020s, with initial first injections targeted around end-2029 to early-2030 in alignment with emitters and facility readiness. The project is expected to capture and store roughly 3.3 million metric tons of CO₂ per year, making it one of the largest offshore CCS projects globally once operational. Over its life, the Kasawari CCS scheme is projected to inject approximately 71–76 million metric tons of CO₂ into the M1 field, leveraging proven subsea pipeline infrastructure and reservoir capacity in a deep marine carbonate reservoir. The CCS deployment aligns with PETRONAS’s broader decarbonization strategy and Malaysia’s ambition to develop into a regional carbon storage and CCUS hub, supporting progress toward net-zero emissions goals by 2050 and enabling long-term emissions reduction in the region’s natural gas sector.
