Scientists at Sandia National Laboratories are making waves with a new, more efficient method for powering wave energy converters (WECs) that could revolutionize the way we harness the ocean's power. By taking a co-design approach, the researchers are saying goodbye to the traditional sequential design process that builds the WEC body prior to its control system, and welcoming a synchronized method that promises a stronger and more effective device.
This groundbreaking strategy not only considers the device's performance amidst the unpredictable nature of the sea, but it also introduces a magnetic spring mechanism from Portland State University, which is shaking up the energy game by offering a way to generate more energy at a reduced cost. The magnetic spring acts as the core of the turbine, and its reliance on magnetism, not mechanics, dramatically drops the rate of wear and tear typically seen in conventional systems.
According to the Department of Energy, the team’s research shows that the use of the magnetic spring, when combined with their innovative co-design approach, results in a superior WEC. The Sandia researchers have found that this combination not only optimizes the WEC but also considerably increases its durability.
Lab tests have been promising, proving that this dual advancement could signal a sea change for marine energy developers. As the Sandia team preps to share their findings with the public, the anticipation is that WEC designs across the board will see significant improvements. The design of the magnetic spring is simple, inexpensive, and easily replicable, which stands to benefit the entire marine energy industry.
