Singapore LNG Corporation Pte Ltd (SLNG) and Linde Gas have signed a memorandum of understanding to collaboratively explore the feasibility and development of a Carbon Dioxide (CO2) liquefaction and storage facility, located adjacent to the SLNG Terminal on Jurong Island, Singapore.

The project concept involves using cold energy from the SLNG Terminal’s operations to liquefy CO2, leveraging on the companies’ expertise in carbon capture, liquefaction, as well as cryogenic storage and handling solutions.

The liquefied CO2 (LCO2) would be stored in tanks onsite before eventually being transported for end use. If feasible, this could be the first such facility of its kind in Singapore and the region, where existing cold energy from SLNG is utilised to liquefy CO2, thereby directly capturing CO which may otherwise be emitted into the atmosphere.

“This project allows us to realise SLNG’s cold energy recovery objectives with a twofold benefit – cold energy recovery with high efficiency, as well as effective liquefaction and storage to reduce CO₂ emissions,” said SLNG chief executive Tan Soo Koong.

“Energy Security has been and continues to be of utmost importance to SLNG. At the same time, it is also our vision to catalyse new possibilities in the energy transition and this includes supporting new solutions for a lower carbon future, in step with the Government’s Singapore Green Plan 2030.”

Initially, the project would target to liquefy, store and transport CO₂ for the project partners, but could potentially be scaled up in the future to handle CO2 from more sources, with an open access, multi-user concept.

“Linde has been innovating technologies for carbon management for decades. We believe that the application of our knowledge and experience in carbon capture, liquefaction, and storage together with SLNG’s cold energy capability will be a key innovative and efficient enabler for Singapore’s decarbonisation plans,” added Qian Wen Bin, Linde’s Asia Pacific head of clean hydrogen and decarbonization.
