Industry leaders collaborate to develop Singapore’s first end-to-end decarbonisation process to mitigate climate change
Singapore, 2 July 2020 – Industry leaders, Keppel Data Centres, Chevron, Pan-United and Surbana Jurong, with the support of the National Research Foundation, signed a Memorandum of Understanding (MOU) today, committing to harness their combined resources and jointly develop the first end-to-end decarbonisation process in Singapore. This collaboration is aimed at accelerating the development of a highly integrated clean and energy efficient Carbon Capture, Utilisation & Sequestration (CCUS) system that can lead to a low-carbon economy and potential commercial developments for Singapore.
Carbon emissions make up 97% of Singapore’s total greenhouse gas emissions. Under the Paris Agreement, Singapore has pledged to, by 2030, reduce its emissions intensity by 36% from 2005 levels, and to stabilise its emissions and peak around 2030. The Singapore Government has announced its long-term strategy to halve emissions from its 2030 peak and achieve net-zero emissions as soon as viable. To this end, the partnership will develop CCUS technologies that are readily applicable, with high technical readiness and cost efficiency to implement in Singapore’s key industries such as energy, chemicals and construction.
Under the MOU, Keppel Data Centres, Chevron, Pan-United and Surbana Jurong will jointly explore, identify and develop mature carbon capture technologies, coupled with novel technologies that utilise cryogens, membranes and hydrogen. The four companies will also leverage the combined resources, knowledge and capabilities with other research partners, Institutes of Higher Learning and international partners to advance the development of the CCUS technologies.
When commercially viable, the CCUS technologies are expected to help reduce carbon intensity across the industry sectors and help Singapore halve emissions from its peak to 33MtCO2e by 2050, with a view to achieving net-zero emissions as soon as viable in the second half of the century.
Mr Thomas Pang, CEO of Keppel Telecommunications & Transportation, the parent company of Keppel Data Centres, said, “Keppel is committed to sustainable development and combatting climate change. This MOU augments the different efforts that the Group has taken to reduce the carbon footprint of data centre operations, including exploring floating data centres as well as LNG and hydrogen infrastructure for power generation. The CCUS technologies are scalable and can potentially be implemented in Keppel Data Centre’s local and overseas operations, as well as other parts of the Keppel Group, thus contributing to the circular economy and advancing climate action.”
“Chevron shares the society’s concerns about climate change. We are committed to advancing technologies and forming strategic partnerships in our efforts to deliver reliable, and ever cleaner energy. I am excited that Chevron will be working with like-minded partners in Singapore to progress polymeric membrane research for carbon capture solutions across various applications and industries. These efforts take us a step further along in Singapore’s and the energy industry’s long-term, low-emissions development strategy.” said Mr Law Tat Win, Chevron Singapore Country Chairman.
Ms May Ng, Chief Executive Officer of Pan-United Corporation Ltd, said, “Multi-industry collaboration is a key strategy to innovate commercially viable clean technologies that can decarbonise the built environment. I am confident that Pan-United’s industry-leading research and development of specialised ready-mix concrete technologies can contribute to this landmark collaboration to combat the adverse effects of climate change. Pan-United is fully focussed on creating concrete solutions in embodied carbon reduction technologies to advance Singapore’s sustainability ambitions.”
Mr Wong Heang Fine, Group Chief Executive Officer of Surbana Jurong said, “As a multidisciplinary urban and infrastructure design consultancy, Surbana Jurong is providing step change solutions for sustainability across the project lifecycle. We are actively engaged in R&D to facilitate decarbonisation, focusing on delivering technologies that reduce and eliminate emissions as well as solutions that remove and sequester carbon from the atmosphere. Together with our partners, we are excited about exploring new solutions in carbon capture, use and storage that can scale and be commercially deployed to help us get to a net-zero future.”
Professor Low Teck Seng, Chief Executive Officer of the National Research Foundation (NRF), said, “Investing in low-carbon R&D to drive cost-effective solutions is crucial for Singapore in our journey towards a low-emission economy. While Singapore, like the world, is still dependent on fossil fuels for our energy needs, technologies that enable efficient CCUS would help mitigate our emissions greatly. CCUS also presents opportunities for converting carbon dioxide into novel chemicals, materials and fuels, offering potential in growing new industries. This MOU demonstrates commitment from both industry and researchers to co-develop innovative solutions to achieve Singapore’s long-term carbon goals of net-zero emissions.”

Annex B: Carbon Capture, Utilisation and Sequestration (CCUS) system and value chain
In the first stage of the CCUS system – Primary Carbon Capture. Membrane separation technology is currently limited by the selectivity of currently available membrane materials as well as the high cost of materials. One of the most promising gas separation method is using polymeric membrane that acts as the filter for the separation CO2/N2 mixtures and generates a specific gas rich permeate.
In the second stage of the CCUS system – Cryogenic Carbon Purification. Cryogenic Carbon Capture is a post-combustion technology method that cools CO2-laden flue gas to desublimation temperatures (-100 to -135 °C), separates solid CO2 that forms from the flue gas from the light gases, uses the cold products to cool incoming gases in a recuperative heat exchanger, compresses the solid/liquid CO2 to final pressures (100-200 atm), and delivers a compressed CO2 stream separated from an atmospheric pressure light-gas stream. Overall resulting in significantly reduced fixed capital and operational capital, especially with the availability of waste cold from LNG regasification.
In the third stage of the CCUS system – CO2 Sequestration Processes. Sequestration projects today are limited at oil/gas fields for subsequent EOR utilisation. The cost for storage, transport and sequestration of CO2, particularly in land scarce Singapore is expected to be high. However, aggregation of the captured CO2 and storing in liquid phase in pipelines networks (used as cold energy transfer medium etc.) or in solid phase in unused storage tanks or caverns could potentially provide alternative commercially viable options.
In the last stage of the CCUS system – Carbon utilisation. There are three tracks that will be explored:
Low-Carbon Concrete: This concrete with a much reduced carbon footprint is achieved by maximising the use of ground granulated blast furnace slag or GGBFS (a cementitious by-product of steel production) to replace ordinary Portland cement, which has high carbon emissions. In addition, natural aggregates are replaced by recycled concrete aggregates and washed copper slag. Carbon dioxide is injected into the concrete mix, converting the carbon
dioxide into a mineral that increases the concrete strength, enabling less cement to be used. The final product is a very low carbon concrete that has a carbon footprint approximately 46% lower than normal concrete.
Mineralisation: Carbon sequestration in construction materials (cement, sand, aggregates etc.) can be achieved through the introduction of carbonates. One of the primary objectives of concrete sustainability innovation is to increase the carbon dioxide (CO2) sequestration in such materials and consequently enable it to still meet construction industry standards.
Methanol: Green methanol production, i.e. methanol synthesised via direct CO2 hydrogenation or via syngas hydrogenation after the reverse water-gas-shift reaction, rather than from methane reforming, can be a highly attractive CCU pathway for a future low-carbon economy.
