World’s largest facility to help remove CO2 from the ocean to begin operations in S’pore in 2026

Within the plant, an electrical current is passed through the seawater. This leads to a series of chemical reactions that split the water (H2O) into hydrogen (H2) and oxygen (O2). The dissolved CO2 is combined with minerals in seawater like calcium and magnesium to produce limestone and magnesium bicarbonates, which Equatic said can trap the CO2 for at least 10,000 years.

The process mimics the natural formation of seashells, and the solid calcium and magnesium-based materials can either be stored on the ocean floor, or potentially be used for construction materials.

In the meantime, the process also produces hydrogen, which is a clean source of energy. PUB had said that the planned facility could produce 300kg of hydrogen daily, which can power the plant or be used in other industrial applications.
