The Indonesian Ministry of Energy and Mineral Resources has announced that it will soon issue a ministerial regulation on Carbon Capture and Storage (CCS) and Carbon Capture, Utilization, and Storage (CCUS). This regulation will include operating permits, CCS/CCUS in the oil and gas sector, carbon definitions, storage capacity, measurement reporting and verification (MRV), cross-border CO2 transport requirement, carbon value, guarantee fund, and operational safety.
Indonesia has 15 CCS/CCUS projects under study or preparation, spread from west to east across the country, including Tangguh EGR/CCUS projects, Abadi CCS, Sukowati CCUS/EOR, Gundih CCUS/EGR, Pilot Test CO2 Huff and Puff Jatibarang, Ramba CCUS/EOR, CO2 Huff and Puff Gemah, Sakakemang CCS, Arun CCS, Central Sumatra Basin CCS/CCUS Hubs, Kutai Basin CCS Hubs, Asri Basin CCS/CCUS Hubs, CCU to Methanol RU V Balikpapan, East Kalimantan CCS/CCUS Study, and Blue Ammonia + CCS Donggi Matindok. Indonesia has a total CO2 storage potential of 577.6 Gt, with 572.8 Gt in saline aquifers for CO2 storage and 4.8 Gt in depleted oil and gas fields.
Cost estimates for CCS projects vary, depending on the project, from US$33/tCO2 for the Tangguh LNG CCS project in West Papua (investment of US$1.4bn for 2.5-3.3 MtCO2/year), to US$43-53/tCO2 for the Gundih project in East Java (US$105m and 0.3 MtCO2/year) and to US$50-55/tCO2 for the CCS project at the Tanjung Enim (South Sumatra) coal gasification project (US$1.6bn and 3 MtCO2/year).
