Episode Intro:
California is in its deepest drought in 1,200 years, and Robert Bergstrom reckons that without the ocean the state would have to depopulate. He spent decades building desalination plants the traditional way: on land, pumping seawater up, pressurising it, and pushing salty brine back out. Now he is sinking the membranes 450 metres down and letting the ocean's own pressure do the work for free. No high-pressure pumps, no marine life caught in the filters, and a far weaker brine.
Robert's bio:
Robert Bergstrom is the founder and CEO of OceanWell, a Californian water technology company building subsea desalination. He has worked on desalination since 1996 and came into water from a career in finance. He founded Seven Seas Water, growing it from two people in a pickup truck into a business that built and operated plants across the US Virgin Islands, the Bahamas, and other Caribbean islands. He retired in 2012, then came back to solve the problem he had spent his career working around.
OceanWell was founded in 2019 with Charlie McGarraugh and Michael Porter. Its pods sit roughly 450 metres below the surface, where natural hydrostatic pressure drives reverse osmosis instead of high-pressure pumps. Each pod is about the size of an upright school bus and can produce up to a million gallons of fresh water a day. The company raised an $11m Series A backed by Kubota, is developing Water Farm 1 in California's Santa Monica Bay with a group of regional water agencies including Las Virgenes Municipal Water District, and has signed an MOU with Eau d'Azur to develop a demonstrator off Nice.
