The Association of Southeast Asian Nations (ASEAN) comprises the countries of Indonesia, Vietnam, Malaysia, Thailand, the Philippines, Singapore, Myanmar, Laos, Cambodia, Brunei, PNG and East Timor. Despite total CO₂ emissions from these nations amounting to nearly 2 gigatons in 2024, only Indonesia, Vietnam, Malaysia Thailand and East Timor are actively pursuing CCS projects. This presentation briefly summarises the various projects in these nations. Indonesia is committed to achieving net-zero emissions and is actively pursuing the development CCS technology with a vision of establishing itself as a regional CCS hub. This initiative is not limited to domestic CO₂ capture, but also seeks international participation. The Indonesian government estimates a substantial CO₂ storage potential ranging from 400 to 600 gigatons within depleted reservoirs and saline aquifers.  Indonesia has identified 27 CCS/CCUS projects that are currently in the study and preparation phase.  Many of these projects are anticipated to be operational by 2030. To fulfil these ambitious commitments, Indonesia has implemented specific regulations to promote CCS. The first commercial scale project is BP’s well-advanced Tangguh CCUS project in West Papua inaugurated on 24 November 2023, with its first carbon injection expected to take place in 2026. Indonesia is taking advantage of UNFCCC’s Joint Crediting Mechanism (JCM) in partnership with Japan. Malaysia has 2 major regions where it is investigating CCS. The Malay Basin has multiple offshore gas fields in various stages of depletion which are being screened for their potential as storage sites. The most advanced project, however, is in the Sarawak Basin, where Petronas has made its final investment decision FID for capturing CO₂from the Kasawari gas field (25% CO₂) and transporting it via a 135km subsea pipeline to the depleted M-1 gas field. Similar plans are in place for taking CO₂ (17%) from the Lang Lebah field for injection into the Golk depleted field. Malaysia has entered into numerous partnerships and collaborations with global CCS investors in Japan and Korea and has set up the world’s first Sharia-compliant Carbon market. Vietnam has begun site selection in its Song Hong Basin with plans to inject more than 1 mta into a number of promising sites where site characterisation is underway in Blocks 103-104-107. Thailand’s national upstream company PTTEP is gearing up to develop the country’s first carbon capture and storage (CCS) project at its producing Arthit offshore gas field. Preliminary front-end engineering and design (FEED) work has commenced, and the Arthit CCS project is expected to commence operations by 2026.East Timor is undertaking a major CCS project overview for its foundation project to transport CO₂ from Darwin LNG facility for storage in the in Bayu-Undan depleted gas field. The field is well characterised and understood through decades of exploration, appraisal and production data, making it an ideal storage target. Singapore has initiated the S-Hub project plans to capture and securely store CO₂ emissions from Singapore’s industrial sources, with ExxonMobil and Shell selected to work with the Government of Singapore on a CCS value chain capable of capturing and permanently storing deep underground or under the seabed at least 2.5 million tons of CO₂ a year, by 2030.
