Sandia Labs’ findings have helped Atmocean attract about $3.5 million in investment to continue product testing, add staff and boost component manufacturing at Reytek. The company built full-size seawater pumps and tested the system off the coast of Oregon in 2011 and off Peru for six months in 2015. “The first Peru tests were a big success,” Kithil said. “Other small communities want to see if it will work for them.”

Atmocean is working now with Sandia Labs engineer Tim Koehler on computational modeling of the wave energy system. Following trials in a test tank at the Texas A&M University Haynes Laboratory, the system will be deployed later in the year off the coast of Newfoundland for a third round of testing that will demonstrate the prototype in an operational environment.

Atmocean’s system is a 200-foot by 200-foot array of pumps floating on the ocean. “Each pump is a buoy on a piston,” Koehler said. “As a wave passes, the buoy ingests sea water, and as the buoy settles, it pumps seawater through hydraulic lines back to shore where it enters the zero-electricity desalination process.”
