The Singapore Government has said that both hydrogen and carbon capture, utilisation and storage (CCUS) technologies will play an important role in the country’s low carbon future.
Such conclusion is based on the results of two feasibility studies, on low-carbon hydrogen and CCUS, that highlighted great potential for the technologies.
The Study of Hydrogen Imports and Downstream Applications for Singapore showed that hydrogen has the potential to diversity Singapore’s fuel mix towards low-carbon options for electricity generation, heavy transportation and some industrial processes.
However, the study also showed that, given Singapore’s limited renewable energy resources, it is challenging for the country 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. Such findings were gathered by the National Climate Change Secretariat (NCCS), Singapore Economic Development Board (EDB), and Energy Market Authority (EMA)
In terms of CCUS, the Carbon Capture, Storage, and Utilisation: Decarbonisation Pathways for Singapore’s Energy and Chemicals Sectors study identified that carbon emission, mainly from power plants and industrial facilities, could be captured and stored in suitable sub-surface geological formations or converted into useful products.
It is expected that the findings from these studies will help guide Singapore’s low-carbon strategy, helping to develop the hydrogen supply chain to amplify the effectiveness of its decarbonisation strategy.
The next step for Singapore will be to seek partnerships with other countries to advance emerging low-carbon technological solutions. Such collaborations could include joint contributions to international regulations, standards and certification on emerging technologies in addition to joint research and development testbeds.
Singapore has already signed a Memorandum of Understanding (MoU) with Australia on low-emissions technologies, a MoU with Chile on low-carbon hydrogen and is actively in discussions with other like-minded countries.
