A Finnish Company Is Advancing In The Renewable Energy Sector With The Launch Of A New Technology Capable Of Generating Energy From Ocean Waves. Known As Wave Energy, This Innovation Promises To Revolutionize The Energy Sector, Offering A Sustainable And Highly Efficient Source Of Energy.
The search for new sources of renewable energy has led humanity to explore the four elements in impressive ways, transforming them into powerful energy sources, as is the case with tidal energy. Today, plants generate electricity from coal, gas, river water, wind, and sunlight. However, leaving 70% of the planet underutilized is seen as an unacceptable waste by energy experts. Now, scientists are turning their attention to the ocean, which covers most of the Earth, and claim that the sea could be the world’s largest battery. Wave energy, also known as wave energy, is being pointed out as the next big revolution in the energy sector, promising to transform the way we power the world.
With this innovation, the ocean can become an inexhaustible source of clean energy, paving the way for a more sustainable and accessible future.
Tidal Energy Has Been Used For Centuries
Theoretically, along the coast of the United States, the annual potential for wave energy is estimated at 2.64 trillion kWh, equivalent to about 64% of the total electricity generation in the United States in 2021.

Iran enters the center of a climate alert after the war emitted 5.6 million tons of CO2 in two weeks, surpassing the annual pollution of entire countries.
For over a century, scientists have been trying to convert wave energy into electricity. The first of these attempts was in 1799, when a request for the construction of a Wave Mill arose at the patent office in Paris. This idea was developed for a good time and gradually transformed into a wave turbine project that for a long time was the most popular solution.
The project would be located below the wave flow and would be powered by the air that the wave displaces from a special chamber. The main disadvantage of this method of using tidal energy is due, curiously, to the laws of physics and the enormous potential of energy, as the waves would easily crush the steel blades of hydraulic turbines, meaning that such a station could not withstand strong waves.
Oceanographers and economists have discussed this project for using wave energy and pointed out that the infrastructure of the Plant could harm marine flora and fauna.
Discover The New Technologies That Generate Wave Energy
There are several technological approaches to capture wave energy. Some of the most promising include:
Oscillating Water Columns (OWC): This technology uses the up and down movement of the waves to compress and decompress air within a chamber. The variation in air pressure activates a turbine, generating electricity. The simplicity and durability of this technology make it one of the favorites for offshore projects.
Wave Energy Converters (WEC): WECs are devices that float on the ocean’s surface and capture wave energy as they are moved up and down by the waves. This kinetic energy is then converted into electricity. Different designs, such as buoy oscillation devices and serpentine devices, are being tested to maximize efficiency.
Energy Accumulators: Projects like Wave Dragon use a raised water collection system, where the waves drive water to an elevated dam. The water then returns to the sea through turbines, generating electricity. This method combines aspects of hydroelectric dams with wave energy, providing a hybrid approach.
Companies Leading The Revolution With Wave Energy Generation
Several companies around the world are at the forefront of wave energy development:
Pelamis Wave Power: This British company was a pioneer in snake technologies to capture wave energy. Although Pelamis faced financial challenges and ceased operations, its innovations continue to influence the sector.
Ocean Power Technologies (OPT): Based in the United States, OPT developed the PowerBuoy, a floating device that converts wave motion into electricity. The PowerBuoy has already been successfully tested in various parts of the world, demonstrating the commercial viability of wave energy.
Wave Swell Energy: This Australian company is developing an enhanced version of the oscillating water column. Its project in King Island, Tasmania, is among the most advanced, and the energy generated is fed into the local electrical grid.
CorPower Ocean: Based in Sweden, CorPower has developed a highly efficient buoy technology that can capture large amounts of energy with relatively small devices. With support from the European Union, CorPower is preparing to implement its systems on a large scale.
Finnish Wave Energy Technology Gains Traction In The Clean Energy Market
Thinking about how to make wave energy useful, two neuroscientists founded the Finnish company AWEnergy, which converts tidal energy into electricity. Between 2019 and 2021, this innovative renewable energy generator from the company underwent field testing on the coast of Portugal with impressive results. The system, called Wave Roller, is impressively simple.
It consists of a moving panel and a power system, which are placed on the sea bed. The panel is powered by wave energy, hydraulic pumps are attached to the panel, and pump the fluid inside a closed circuit. Other high-pressure fluids are fed into the energy storage system connected to the hydraulic motor, directly powering the renewable energy generator.
The Wave Roller has several advantages when compared to wind farms, which are more popular these days. Visually, they are not intrusive and are firmly installed on the sea floor at a good depth. In addition, their source of propulsion, tidal energy, is much more reliable since waves, unlike wind, are regular and therefore predictable.
New Wave Energy Technology Could Revolutionize The Sector
In tests of the tidal energy plant, even a prototype was able to provide 350 kW of power. The Wave Roller passed all tests with flying colors thanks to its design features. The load that wave energy puts on the converter is offset by the fact that it is located on the seabed and therefore has a lower center of gravity than any turbine.
The results make it clear that the company’s plans to dominate tidal energy have every chance of becoming a reality. AWEnergy has already become a member of the revolutionary Neste Veturi initiative, securing its support and that of its partners. This also solidifies the success already demonstrated in repeated tests with the Solar Impulse Efficient Solution, providing environmental accountability and economic profitability to the Wave Roller.
