said that the planned facility could produce 300kg of hydrogen daily, which can power the plant or be used in other industrial applications.

The demonstration plant is co-funded by PUB, the National Research Foundation, Singapore, and the University of California, Los Angeles' Institute for Carbon Management.

PUB has a target to achieve net-zero emissions by 2045 - five years earlier than the national target.

Identifying novel technologies is one way by which PUB is trying to reduce its carbon emissions.

The water agency is also trying to replace fossil fuels with renewable energy, such as by putting solar panels on reservoirs, and investing in research and development to reduce energy required in energy-intensive water treatment processes.

The scaling up of the novel technology comes after two smaller pilots proved successful in removing CO2 - one in PUB's R&D desalination plant in Tuas, and the other in the Port of Los Angeles.

Set up in April 2023, each pilot plant was able to remove 100kg of the greenhouse gas from the ocean each day.
