Can this ocean-based carbon plant help save the world? Some scientists are raising red flags

Editor’s Note: CNN Films ”Blue Carbon: Nature’s Hidden Power” takes viewers from the mangroves of Vietnam to the salt marshes of France to investigate a powerful new ally in the battle to slow climate change. It premieres at 9 p.m. ET/PT Sunday, April 21.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.It’s a compelling vision of a potential solution in the face of a worsening climate crisis that has fueled unprecedented heat and devastating extreme weather. Efforts to rein in global heating remain hugely off track, and many scientists are now warning that, in addition to rapidly reducing fossil fuels, the world will also need to remove carbon pollution humans have already pumped into the atmosphere.This 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, as a tool to do this. Other projects include sprinkling iron particles into the ocean to stimulate CO2-absorbing phytoplankton, sinking seaweed into the depths to lock up carb …
