Wave Power

Creating Electricity for the Ocean

“Eco Wave Power has successfully developed and commercialized wave energy.”

By Linn Smith

Eco Wave Power is a company founded in 2011 which is the only company in the world that turns ocean waves into clean energy, connecting wave floaters to the power grid. Since 2016 the Wave Farm has been providing Gibraltar, a tiny country bordering Spain, with electricity. Eco Wave Power is also a 2019 recipient of the United Nation’s Climate Action Award.

Clean and Affordable Energy

According to the U.N. Climate Action organization,”The project generates clean and affordable electricity, using a simple design that allows the project’s uniquely shaped floaters to be attached to existing man-made structures (such as piers, breakwaters and jetties), and thereby simplifying the installation process, as well as maintenance and accessibility.”

How Wave Energy Works

The converter consists of three main functional parts: mechanical, hydraulic and electric systems. The mechanical system serves as a wave energy receiver on floaters and transmits the energy to hydraulic cylinders. The hydraulic system transforms the mechanical energy from the sea to hydraulic fluid pressure and forces a hydraulic motor rotation, which transfers the energy from rotation to the generator. The generator is part of a converter electrical system. It receives the energy from rotation and transforms it to electrical power.

Key Facts according to U.N. Climate Action

*Wave energy has historically been uncommercialized due to the complexity of extracting energy from the ocean. This project has successfully developed and commercialized wave energy, resulting in a grid-connected array that has operated continuously since 2016.

*In 2018, the station set a world record for wave energy when it clocked over 15,000 grid-connection hours.

*Commercializing wave energy has enormous potential — the World Energy Council predicts that wave energy can produce twice the amount of electricity the world currently produces.

*More than half the world’s population lives within 100 km (62 miles) of a coastline, and in many locations, the power of the waves is available around the clock.

Being easy to build and cost efficient these floaters also have little negative impact on the environment. Gibraltar has been a test site and Eco Wave’s plan for further expansion are on the horizon!

My goal, as a responsible adult, is to leave a planet that people, plants, and animals can continue to occupy comfortably. I am an educator by profession. While educating myself on Climate Change and Renewable Resources, I hope to share my knowledge and images with those that share my concern. Dr. John J. Hidore is a retired professor from the University of North Carolina at Greensboro and I am proud to call him my Uncle. His work has taken him to regions across the globe—including the Middle East, where he conducted research for a year in the Sudan. He has written many books, such as Climatology: An Atmospheric Science and Global Environmental Change.----Linn Smith Planet Earth Weekly recently passed 30,000 views!
