Harvesting Ocean Wave Energy via Magnetoelastic Generators for Self-Powered Hydrogen Production.

ABSTRACT: Extracting energy from ocean waves for electrolysis, while highly desirable, poses significant challenges, especially in achieving high current generation for sustainable water splitting. This work introduces an innovative high-current ocean wave energy harvesting system, employing a self-floating magnetoelastic generator (MEG) ball network designed for autonomous seawater electrolysis and on-site hydrogen (H₂) production. Leveraging the magnetoelastic effect, the MEG ball network is naturally waterproof and can generate a high current density of 0.24 mA cm^-2, paired with a low internal resistance of 9 Ω at a wave frequency of 2 Hz. Its spherical design ensures exceptional mechanical durability, maintaining consistent electrical output even under extremely humi
