Proposed U.S. Wave Energy Research Center in Newport, Oregon
- Oregon and Oregon State University are ideally located with some of the best wave energy
potentials world wide.
- OSU has three key laboratories available to advance wave energy research.

and Renewables Facility Research Laboratory Science Center
SeaBeav testing Oregon State University researchers are
pursuing “direct drive” technologies, where the
force and velocity of the water is directly
coupled to electrical generation without
intermediate hydraulics or pneumatics.
Survivability is paramount for ocean energy
devices. By removing intermediate conversion
stages, overall system efficiency and reliability
can be increased.
Several Oregon State University wave energy
devices use magnetic flux linkage across a
seawater airgap. This removes the need for
watertight moving seals.
