successfully assessed the underground storage capacity of CO2, marine transportation from CO2 emission sources,
and the most effective CO2 storage scheme for the purpose of permanent storage at offshore Malaysia. Based on theconclusion of Joint Study, that targeting the depleted oil and gas fields and the associated aquifers, identified
offshore Malaysia, will maximize practicality of CO2 storage and feasibility of the earliest commercialization, we
have agreed to execute the CCS Project Development jointly.
The KPA will commence the specific preparatory works with a view of beginning the front-end engineering designin 2024 and the subsequent construction works, aiming to inject and store CO2 from Malaysia and Japan in the endof 2028. We will proceed with the detailed engineering of the specifications, estimated costs, and business scheme,including infrastructure network of CO2 pipelines from onshore gathering, receiving facilities for liquefied CO2transported by ships and offshore injection facilities. PCCSV and JC will work closely with other Malaysian
stakeholders for the development of the CCS hub in Malaysia.
PCCSV and JC will execute the CCS Project Development aiming for the final investment decision on thecommercialization in the mid-2020s and the operation commencement by the end of 2028. The target amount ofCO2 injection is to be at least about 2 million tons per year at the beginning of the project, including that fromMalaysia and Japan, and 5 million tons per year by 2030, with a view to increasing the amount to more than10
million tons per year in the early 2030s.
In addition, the JC will continue the joint evaluation (hereinafter the “Joint Evaluation”) aiming to establish theCCS value chain originated from Japan with JFE Steel Corporation (*2) since this June and will manage to1 / 3

collaborate between the Joint Evaluation and the CCS Project Development.
