On a slice of the ocean front in west Singapore, a startup is building a plant to turn carbon dioxide from air and seawater into the same material as seashells, in a process that will also produce “green” hydrogen — a much-hyped clean fuel.
The cluster of low-slung buildings starting to take shape in Tuas will become the “world’s largest” ocean-based carbon dioxide removal plant when completed later this year, according to Equatic, the startup behind it that was spun out of the University of California at Los Angeles.
The idea is that the plant will pull water from the ocean, zap it with an electric current and run air through it to produce a series of chemical reactions to trap and store carbon dioxide as minerals, which can be put back in the sea or used on land.
The Singapore plant is one example of a slew of recent projects that are looking to the oceans, which already absorb almost 30% of humanity’s planet-heating pollution.
But carbon-removal projects are controversial, criticized for being expensive, unproven at scale and a distraction from policies to cut fossil fuels. And when they involve the oceans — complex ecosystems already under huge strain from global warming — criticisms can get even louder.
