Ocean Wave Energy Systems

A variety of technologies have the potential to capture that energy and some of the more.

Ocean wave energy systems.

The waves that animate the surface of the oceans represent a deposit of renewable energy that for the most part is still unexploited today. A machine that exploits wave power is a wave energy converter wec. The energy in waves comes from the movement of the ocean and the changing heights and speed of the swells. The oceans and seas constitute about 70 of the earth s surface area so they act as a large reservoir of solar energy.

Wave energy is a blend of both kinetic and gravitational potential energy of ocean waves created as a result of the wind blowing over the surface. Open ocean power grid connected wave energy test facility about six nautical miles off the coast of newport ore. The pacific marine energy center has been awarded 40 million in funding to build the first u s. An average 4 foot 10 second wave.

With a growing need for clean energy sources to complement wind and solar there is an increasing need for new technology to be developed. Kinetic energy the energy of motion in waves is tremendous. One example of this is ocean wave energy technology which can be deployed alongside wind and solar to add more renewables onto the grid and reduce greenhouse gas emissions as a whole. Ocean waves contain tremendous energy potential.

Advantages of wave energy 1 2. Waves kinetic and potential energy associated with ocean waves can be harnessed using modular technologies. Ocean energy is an indirect form of solar energy. Wave power devices extract energy directly from the surface motion of ocean waves.

This is not for lack of effort as for more than two hundred years inventors researchers and engineers have struggled to develop processes and systems to recover the energy of the waves. Wave energy is an irregular and oscillating low frequency energy source that can be converted to a 60 hertz frequency and can then be added to the electric utility grid. Iea technology collaboration programme on ocean energy systems has published in depth inte. In many areas of the world the wind blows with enough consistency and force to provide continuous waves along the shoreline.

What is wave energy. Limitations of wave energy 2. Grid connected wave energy test facility became fully operational in july at a military base in hawaii. Wave power is distinct from tidal power which captures the energy of the current caused by the gravitational pull of the sun and moon waves and tides are also distinct from ocean.

Wave power is the capture of energy of wind waves to do useful work for example electricity generation water desalination or pumping water.
