Tuas facility to demo mCDR tech begins 2026

The Singapore plant takes in seawater from adjacent desalination plants will initially have the capacity to remove 1 tonne of CO2 per day from seawater. When fully operational it will be able to remove 10 tonnes of CO2 from seawater daily. 

NParks had noted that the demonstration project will have minimal impact because the seawater is returned to the ocean without altering the ocean chemistry. When the project is ready to be scaled up, NParks will work with PUB, Equatic and other stakeholders to regularly review and ensure that required environmental quality objectives are met.

Details on Coastal Protection at the South and Changi announced

Details on a “continuous line of defence” at the South and at Changi was announced. As part of its study, the agency had considered feedback from stakeholders, including experts, nature groups and youth about preserving direct access to the sea. Construction is slated to begin in the 2030s. 

If no action is taken, widespread flooding could happen in the City-East Coast region during extreme coastal storm surges in 2050. 

At Changi Beach Park, PUB will be constructing a raised platform farther inland to ensure access to the beach and preserve the seagrass-rich shores. This means the beach will be left to temporarily flood during extreme high tides. Safety measures will be put in place to guide beachgoers away when extreme coastal weather is forecast.

PUB said it had incorporated feedback from the community and nature groups to preserve habitats and visitor access in deciding on this measure.

Mr Muhammad Nasry Abdul Nasir, executive director of Singapore Youth Voices for Biodiversity, said: “Let the tidal areas flood. That’s what they do. I would prefer if the bund is set as far back as possible inland to allow intertidal areas and seagrass meadows to retreat with sea level rise.”

Mr Ho Xiang Tian, co-founder of environmental group LepakInSG, said: “I’m glad to hear this because our shorelines are being squeezed everywhere and this gives some breathing room for the Changi intertidal shores.”

Ms Hazel Khoo, director of the Coastal Protection Department at PUB, said that Singapore's coastal protection requires "innovative solutions" that go beyond traditional approaches.

"Coastal protection requires long-term and careful planning, and trade-offs are inevitable. There are still coastlines with unique characteristics that we will need to conduct site-specific studies progressively," she said, adding that PUB will explore solutions that balance diverse priorities.

PUB's "Riding the Tides" exhibition on coastal protection: 28-31 Aug

A great way to learn about plans for coastal protection, and see some of the ideas and comments from the public. Plus fun activities for the whole family. 

Bravo to PUB for their public outreach through the exhibition: "Riding the Tides" 28-31 Aug. And their encouragement to reimagine our shores. I am heartened by the inclusion of nature-based solutions, and the cultural and emotional value of shores.  

Aug 2025: Surveys off East Coast Park for Long Island design

From August 2025, HDB will be conducting site investigation works in the waters off East Coast Park for a few months. These initial studies will gather essential information, such as an understanding of the geological and seabed conditions, which will guide the project's detailed design and planning.

The barges will remain at each investigation site for one to three days, using onboard rigs to conduct borehole drilling, soil sampling and in-situ field tests. Survey boats will carry out side scan sonar, geographical and cable detection surveys. The works are not expected to result in pollution or environmental impact.

Nature based solutions to protect Singapore coastlines

The Coastal Protection and Flood Resilience Institute (CFI) Singapore set up to identify innovative solutions for coastal protection, now has 17 research projects funded by PUB’s $125 million Coastal Protection and Flood Management Research Programme. Solutions considered include a flexible seawall with adjustable heights can also support a concrete structure that allows for multi-function uses, such as a road or a park. Also tube-like barriers of natural materials to line the shore which not only shield the beach from strong waves but also allow sand and soil to slowly accumulate and raise the shores, turning the beachfront into a natural sea wall of sorts, to catch up with higher sea levels. Other ideas include XblocPlus - a flexible and scalable design that minimises land take and can be integrated with urban developments or natural habitats. 

Experts highlight that there might be a situation where some parts of the island – more remote and with lower footfall – may be left to flood once in a while. These floodable areas could be coastal parks, nature spots and beach areas. “Certain places could tolerate flooding for a few hours before it subsides. If it’s a parkland, you just have to close it for a few hours… It doesn’t mean that you have to stop every centimetre of flooding. You cannot protect everything.”

Is Terumbu Bemban impacted by the Sudong reclamation?

The team surveys one of our favourite sites, a submerged reef flat that is the closest to the ongoing reclamation at Pulau Sudong.

So far, the shore is still alive! We didn't check the shore at peak mass coral bleaching last year. So it was a relief to see the coral situation seems as usual. Also a nice to surprise to see denser growths of seagrasses throughout the reef flat. The rest of team find Giant clams, encounter huge jellyfishes, special sea anemone and the usual colourful reef life.
