The Singapore Government is following up on the findings from two feasibility studies on low-carbon hydrogen and on carbon capture, utilization, and storage (CCUS) technologies respectively. 

According to a consortium consisting of the National Climate Change Secretariat (NCCS), Singapore Economic Development Board (EDB) and Energy Market Authority (EMA), these technologies play important roles in the region's transition to a low-carbon future and will help assist in efforts to meet commitments set out in its enhanced 2030 Nationally Determined Contribution and Long-Term Low-Emissions Development Strategy, and the Singapore Green Plan 2030.

In the "Study of Hydrogen Imports and Downstream Applications for Singapore," it is suggested that hydrogen has the potential to diversify Singapore’s fuel mix towards low-carbon options for electricity generation, heavy transportation and some industrial processes. Given Singapore’s limited renewable energy resources, it is challenging for Singapore to produce green hydrogen at scale using domestic green electricity. As such, Singapore would need to explore various supply pathways for price-competitive low-carbon hydrogen.

The second study, "Carbon Capture, Storage, and Utilization: Decarbonization Pathways for Singapore’s Energy and Chemicals Sectors," identified carbon dioxide emissions, mainly from power plants and industrial facilities, that could be captured and stored in suitable sub-surface geological formations (i.e. CCS) or converted into useful products (i.e. CCU). For CCU, some of the more promising pathways include (i) mineralization, to use waste-based feedstock or natural minerals to produce aggregates for reclamation or structural and non-structural building use, and (ii) conversion to chemicals and synthetic fuels, such as kerosene and methanol, which have the potential to be used as fuel for aircraft and marine vessels. 

Findings from the study will be used to inform existing research, development and demonstration (RD&D) efforts, such as the S$49 MM Low Carbon Energy Research Funding Initiative, a multi-agency effort involving the Agency for Science, Technology and Research (A*STAR), EDB, EMA, NCCS and the National Research Foundation (NRF); and to guide private sector consortiums such as those led by Keppel DC, Chiyoda, and Itochu on the deployment of low-carbon solutions, and the development of the hydrogen supply chain. 

Following the release of the both reports, Singapore will also seek to partner other countries to advance emerging low-carbon technological solutions. Such collaborations could include joint contributions to international regulations, standards and certification on these emerging technologies, and participation in joint RD&D and test-beds. To date, Singapore has signed an MOU with Australia on low-emissions technologies and an MOU with Chile on low-carbon hydrogen, and is actively in discussions with other like-minded countries.
