Startup Aims To Turn The Oceans Into A CO2 Sponge And A "Green" Hydrogen Machine    The 39-year-old director of UCLA's Institute for Carbon Management (ICM) described a method of eliminating the dangerously prevalent greenhouse gas in a way that seemed too good to be true: suck it out of the ocean, allowing it to absorb more CO2 from the air like a giant global sponge. It could be done via a relatively simple electrochemical process miming what nature already does. And a byproduct is hydrogen, arguably the future of storable, carbon-free energy. Proportionally, "ocean water contains 150 times more carbon dioxide than the air, which means if you want to remove carbon dioxide from the atmosphere one of the most effective ways to do it is by removing it from the oceans," he told the audience. Sant's method is more than a science experiment: It's well on the way to commercialization through Equatic, a Los Angeles-based startup that's scaling up the ocean-based CO2 reduction and hydrogen production tech developed by Sant and UCLA scientists. His hope, and that of backers including the Grantham Foundation, Chan Zuckerberg Initiative, Singapore's Temasek Foundation and U.S. Energy Department, which have contributed $30 million so far, is that Equatic will be removing millions of tons of CO2 in the years to come—and do so for less than $100 per ton. Sant also expects the company to generate hydrogen for $1 per kilogram that it can sell or use to help power Equatic's operations. Continued here
