The S-Hub Consortium: Two Oil Majors, One CCS Mission
Singapore’s carbon capture and storage ambitions are anchored by an unusual partnership. ExxonMobil Asia Pacific and Shell Singapore formed the S-Hub consortium to work with the Singapore government as lead developers for a cross-border CCS project.
S-Hub and EDB signed a memorandum of understanding in December 2023 to coordinate a CCS project capable of capturing and permanently storing at least 2.5 million tonnes of CO₂ per year by 2030. The project will store CO₂ emissions from Singapore deep underground or under the seabed, with storage sites to be selected after suitability analysis.
The Feasibility Studies
Two government-commissioned studies have shaped the CCS roadmap. The study on “Carbon Capture, Storage, and Utilisation: Decarbonisation Pathways for Singapore’s Energy and Chemicals Sectors” was jointly commissioned by the National Climate Change Secretariat and EDB. It identified CO₂ emissions mainly from power plants and industrial facilities that could be captured and stored in suitable sub-surface geological formations or converted into useful products.
Promising CCU pathways include mineralisation to produce aggregates for reclamation and building use, and conversion to chemicals and synthetic fuels such as kerosene and methanol for aviation and marine vessels.
The CCUTT Testbed
In June 2026, A*STAR, EDB, and JTC announced plans to study the development of a Carbon Capture and Utilisation Translational Testbed (CCUTT). Researchers will explore CCU approaches with industry players using plug-and-play infrastructure for solvent absorbents, solid adsorbents, and catalysts.
Japan Cooperation and Jurong Rock Caverns
On 15 March 2026, Singapore and Japan signed an Energy, Sustainability, and Climate Change Cooperation Framework covering CCUS, low-carbon hydrogen and ammonia, and civil nuclear energy. Separately, NTU researchers are studying the feasibility of repurposing Jurong rock caverns for dense-phase CO₂ buffer storage.
