Deep-Sea Desalination: A Risky Bet Amid California’s Water Crisis

California’s water crisis has pushed desperation to new depths—literally. OceanWell’s plan to deploy deep-sea desalination technology off the Southern California coast promises an energy-saving way to produce millions of gallons of freshwater daily. Yet beneath the surface, critical concerns simmer about environmental harm, regulatory shortcuts, and taxpayer exposure. Can Deep-Sea Desalination Deliver Without Sacrificing Our Coasts? Desalination may sound like a futuristic fix: using ocean pressure 1,300 feet underwater to filter saltwater more efficiently and cut carbon emissions by 40%. But previous projects reveal harsh tradeoffs. The massive Carlsbad plant, North America’s largest, illustrates how desalination plants strain marine ecosystems...
