What is Wave Power?

Wave power, also known as ocean wave energy, is a form of renewable energy derived from the movement of ocean waves. It involves converting the kinetic energy present in waves into electrical energy that can be used to power various applications. The magnitude of wave power is immense, considering that the total power contained in ocean waves worldwide is estimated to be more than twice the world’s electricity production.^[1]

The Pioneers in Wave Power

Several companies have emerged as pioneers in the field of wave power, developing innovative devices to harness this powerful source of energy.

CETO by Carnegie Wave Energy

Carnegie Wave Energy, an Australian-based renewable energy company, has developed the CETO system, which converts wave energy into electricity and desalinated water. The CETO technology is unique in that it operates underwater, reducing its visual impact and vulnerability to storms. It consists of fully submerged buoys tethered to seabed pumps, which convert the vertical motion of passing waves into pressurized water that drives turbines to generate electricity.^[2]

Key Advantages of the CETO system:

• Minimal visual impact: The fully submerged buoys reduce the visual impact of wave energy devices on the shoreline.
• Resilience: With its underwater design, the CETO system is engineered to withstand extreme weather conditions, ensuring continuous energy production.
• Multiple applications: The CETO system not only generates electricity but also produces high-quality desalinated water, addressing two critical needs in coastal regions.

WaveRoller by AW-Energy

AW-Energy, a Finnish wave energy company, has developed the WaveRoller, a device designed to convert wave energy into electricity. The WaveRoller consists of a hinged panel attached to a fixed structure on the seabed. As waves pass over the panel, it moves back and forth, activating hydraulic pumps connected to a generator to produce electricity.^[3]

Key Advantages of the WaveRoller:

• Reliability: The WaveRoller’s simple build allows for easy maintenance and reliable operation, ensuring continuous electricity generation.
• Modular design: The device’s modular design enables scalability, allowing for the deployment of multiple units to meet varying energy demands.
• Environmental compatibility: The WaveRoller operates silently underwater, minimizing its impact on marine life and coastal ecosystems.

The Future of Wave Power

Wave power technology is still in its early stages, but it holds significant promise for a sustainable future. According to the International Energy Agency, wave energy has the potential to supply up to 10% of global electricity demand by 2050.^[4] However, realizing this potential requires continued innovation and support from governments and investors.

Key Takeaways:

• Wave power harnesses the energy of ocean waves to generate electricity.
• Carnegie Wave Energy’s CETO system uses fully submerged buoys to convert wave motion into electricity and desalinated water.
• AW-Energy’s WaveRoller employs hinged panels on the seabed to generate electricity from wave energy.
• Wave power has the potential to play a significant role in a sustainable future, potentially meeting up to 10% of global electricity demand by 2050.

As the world continues to seek greener and more sustainable energy solutions, wave power pioneers are breaking ground with their innovative wave energy devices, demonstrating the vast potential of this renewable energy source. With ongoing developments and growing support, the dream of harnessing the power of the ocean waves may soon become a reality.
