Feasibility of Carbon Capture and Storage in Singapore Singapore is investigating whether carbon capture and storage (CCS) can play a role in decarbonising its gas-fired power fleet. In July 2025, the EMA selected five proposals from three power generation compa- nies – Keppel’s Infrastructure Division, PacificLight Power and YTL PowerSeraya – to receive co-funding for site-specific CCS feasibility studies. The studies, targeted for completion in 2026, explore two distinct pathways. • Post-combustion carbon capture – installing on- site CO2 capture units to capture carbon dioxide from flue gas produced during natural gas com- bustion in power plants. • Pre-combustion carbon capture – capturing CO2 generated during hydrogen production from natural gas, with hydrogen then used for electricity gen- eration. Separately, GE Vernova and YTL PowerSeraya have commenced a post-combustion carbon capture fea- sibility study for a planned 600 MW hydrogen-ready CCGT plant on Jurong Island, assessing capture technologies capable of capturing up to 90% of CO2 emissions. Collectively, these studies are expected to provide the engineering foundation for subsequent pre-front-end engineering design and front-end engi- neering design work, and to inform whether CCS can be deployed at scale in Singapore’s power sector. Additionally, cross-border CCS opportunities are being explored. In March 2024, the Singapore Gov- ernment appointed S-Hub (a consortium of ExxonMo- bil and Shell) to assist with a cross-border CCS feasi- bility study. Singapore is also partnering with countries such as Australia, Indonesia and Malaysia which have geological storage potential, given Singapore’s own lack of suitable geological formations for long-term carbon storage.
Conclusion Singapore’s energy transition is unfolding across mul- tiple fronts simultaneously. Solar deployment is scal- ing, cross-border electricity interconnections are pro- gressing from trial to commercial scale, biomethane and VPP frameworks are being piloted, carbon pricing and credit mechanisms are maturing, and longer hori- zon options such as geothermal, nuclear and CCS are advancing through feasibility stages. For businesses and investors, this landscape offers a widening set of opportunities from project develop- ment and engineering, procurement and construction work, to technology supply, financing and advisory mandates, and offtake arrangements. The regulatory environment is characterised by structured, govern- ment-led de-risking through sandboxes, grant calls and public-private partnerships. The coming years will be decisive in determining which pathways move from study to deployment at scale.
