Agucadoura Wave Farm in Portugal. The following page lists most power stations that run on wave power, however there are not many operational at present as wave energy is still a nascent technology. A longer list of proposed and prototype wave power devices is given on List of wave power projects.
The potential energy density is equal to the kinetic energy, [1] both contributing half to the wave energy density E, as can be expected from the equipartition theorem. The waves propagate on the surface, where crests travel with the phase velocity while the energy is transported horizontally with the group velocity .
As waves can only reach a certain curvature before naturally breaking, this limits the range of motion through which the machine must move but maintains large motion at the joints in small waves. The Pelamis machine was an offshore wave energy converter, operating in water depths greater than 50 m. [ 4 ]
The Cycloidal Wave Energy Converter is a wave energy concept being developed by Atargis Energy Corporation in Colorado. The patents were filed in 2005, and the company was founded in 2010, after initial research showed potential. [67] It is a fully submerged wave termination device, located offshore, with a direct drive generator.
The tidal barrage makes use of a seawall constructed in 1994 for flood mitigation and agricultural purposes. Ten 25.4 MW submerged bulb turbines are driven in an unpumped flood generation scheme; power is generated on tidal inflows only, and the outflow is sluiced away, i.e. as one-way power generation. [2]
The Department of Energy announced a $22 million grant to fund wave energy research by private companies and universities in January 2022. [3] Academic institutions conducting wave energy research include Portland State University, the University of Washington, and the O.H. Hinsdale Wave Research Laboratory at Oregon State University.

This enables it to extract power from horizontal (surge) as well as vertical (heave) wave motion. [8] It has reserve buoyancy that is very low, allowing it to partially submerge beneath large waves. [11] Point absorber. Azura is a point absorber. This means that it uses a floating surface mechanism to absorb the energy of waves from different ...
SDE Sea Wave is a type of renewable energy power plant technology utilizing sea wave energy for the production of electricity. The SDE Sea Wave technology was developed by the Israeli company S.D.E. Energy LTD from 1996 to 2014. [ 1 ]
