Keppel to explore low carbon solutions for water desalination and treatment

Keppel Infrastructure[1] has signed Memorandums of Understanding (MOU) with subsidiaries[2] of Keppel Infrastructure Fund Management Pte Ltd (KIFM), the Trustee-Manager of Keppel Infrastructure Trust (KIT), to jointly partner on advancing innovations and the development of low carbon water solutions, among other initiatives. These research activities will be undertaken and piloted at KIT-owned facilities, SingSpring Desalination Plant and Ulu Pandan NEWater Plant, as well as Keppel Infrastructure's latest completed desalination plant, Keppel Marina East Desalination Plant.

Under the MOUs, the parties will explore the sequestration and utilisation of carbon, in combination with the capture and utilisation of hydrogen, from seawater. The pilot project will investigate the potential enhancement of electrochemical processes used in water treatment, where by-products such as chlorine and precipitates can be respectively re-used for water disinfection and to produce green construction material. The softened seawater can then be desalinated using less energy and chemicals.

In addition, the parties will explore technologies that can help to improve the efficiency and sustainability of the plants’ operations in desalination, water reuse and wastewater treatment. These include the use of both non-membrane and membrane technologies that can help respectively to improve the quality of feed water for more efficient downstream processing and reduce the energy consumed in treating water.

Er Goh Eng Kwang, Executive Director, Water Services of Keppel Infrastructure said, “As a leading provider of design and engineering solutions for environmental infrastructure and an experienced operator of water treatment plants, Keppel Infrastructure is pushing the envelope for low carbon water solutions. We are exploring the use of advanced technologies at three projects, Ulu Pandan NEWater Plant, SingSpring Desalination Plant as well as Keppel Marina East Desalination Plant, to significantly reduce the environmental impact of producing clean water.

“Through Keppel’s concerted efforts to research and explore innovative solutions, not only can we help our customers reduce their carbon footprint, while increasing the efficiency of their assets, but we are also contributing to sustainable development and climate action in line with our Vision 2030 strategy.”

Mr Marc Liu, Head of Asset Management, KIFM said, “We are pleased to partner our sponsor Keppel Infrastructure in developing energy-saving, low-carbon solutions that will premiere at our water treatment plants. Through this collaboration, we aim to make the operations and maintenance of our assets more efficient, while significantly reducing their overall energy consumption and emissions. This collaborative effort reflects our ESG commitment to contribute towards decarbonisation and provide greener solutions in support of our customers and communities.”
