摘要

India’s rapid industrialization and rising energy demand have driven a sustained increase in CO2 emissions, with an average annual growth rate of approximately 3.1%, highlighting the need for scalable mitigation strategies. Geological carbon sequestration (GCS) has emerged as a technically viable option for the long-term and permanent storage of CO2 emissions from hard-to-abate industrial sectors. This study evaluates the geological CO2 storage mechanisms and suitability of the Cambay Basin, Gujarat, a region characterized by high industrial activity and significant CO2 point sources. The basin possesses favorable geological characteristics, including a well-established sedimentary framework, stacked sequences of depleted oil and gas reservoirs, regionally extensive saline aquifers, and proven caprock systems capable of ensuring long-term containment. These attributes make the Cambay Basin a promising candidate for large-scale CO2 sequestration. A basin-wide storage capacity estimation was carried out using volumetric calculations combined with efficiency-factor—based methodologies. Based on available geological and reservoir data, the total theoretical CO2 storage capacity of the Cambay Basin is estimated at approximately 16.4 Gt. To the best of our knowledge, this mini review provides the first consolidated synthesis of CO2 storage assessments conducted at basin, regional, local, and site-specific scales for the Cambay Basin. The results indicate strong storage potential and overall suitability, supported by favorable porosity, injectivity, and caprock integrity. However, key uncertainties remain, particularly regarding data completeness, site-specific risk assessments, plume migration behavior, and the availability of long-term monitoring and verification infrastructure. The study highlights important implications for deployment and policy support, emphasizing the need for targeted geoscientific investigations, integrated use of legacy hydrocarbon data, basin-scale pilot projects, and the development of robust regulatory and monitoring frameworks. Addressing these gaps will be essential to de-risk implementation and enable the integration of geological CO2 storage into India’s national carbon management strategy, supporting progress toward the country’s net-zero emissions target by 2070.
