Harnessing predictable, clean wave energy becomes more efficient with a highly innovative floating buoy.
Climate goals have become significantly stricter worldwide. To accelerate the transition away from fossil fuels, global energy systems need to diversify.
Solar and wind power may be dominating current global expansion, but they are not enough to ensure long-term grid stability.
Will the ability to harvest the ocean’s kinetic energy be the breakthrough the world has needed all along?
How conventional green power sources are no longer enough
For decades, traditional renewable energy sources have led the global energy transition.
Massive wind farms and solar plants are proof that clean power can scale successfully.
Nonetheless, these progressive technologies are currently facing significant bottlenecks worldwide.
The infrastructure requires optimal, high-yield land for installation, which is mainly limited.
Remaining occupable sites are often too far away from major centers. Connecting remote facilities will significantly increase the investments needed for heavy-duty transmission lines.
Major regional grid connection backlogs are another issue faced by traditional infrastructure developers.
Existing regional utility facilities also lack the means to handle intermittent power surges safely.
Wind and solar energy are inherently intermittent, which can lead to instant drops in electricity generation.
Regions that lack large battery storage frameworks face an increased risk of grid instability.
These limitations are actively slowing down the global green energy shift.
Without progress, nations face failing to meet stricter climate goals.
The risk of an extended fossil fuel era
Earth’s average temperature is rising higher than it should be.
The United Nations has warned that the goal of limiting global warming to 2.7 degrees Fahrenheit is failing.
International climate mandates have tightened to avoid prolonged catastrophic changes in atmospheric conditions.
This can be prevented by cutting greenhouse gas emissions by approximately 45% this decade.
Since the timeline has become so urgent, there cannot be any delays in renewable infrastructure expansion.
However, it is already clear that the bottlenecks of wind and solar power threaten to halt this momentum.
To prevent immediate and potentially life-threatening supply deficits, grid operators must fill these gaps.
Unfortunately, without feasible clean energy alternatives, utilities will turn to fossil fuels.
Moving backwards will only aggravate climate change, erasing years of environmental progress.
That is why the EuropeWave project focused its time and energy on the highly untapped potential of the ocean.
Unlocking wave energy with a floating buoy
Unconventional approaches and unwavering determination will solve the biggest issues in renewable energy.
To find innovative ways to unlock this marine potential, the EuropeWave project was launched.
It is a $22.6 million initiative co-funded by the European Union and regional energy agencies targeting commercial wave energy development.
Multinational firm IDOM engineered an advanced wave energy converter called MARMOK-A-5.
It is a specialized floating buoy, and the majority of the structure remains submerged beneath the ocean.
The mechanics of the MARMOK-A-5
Wave energy is captured using the mechanical principle called an oscillating water column.
Inside the submerged structure is a massive, open-ended cylindrical chamber. Incoming waves force water inside to rise and fall quickly.
The continuous upward movements compress the captured air chamber on top of the buoy.
Water levels drop as waves recede, expanding the air pocket and pulling air down.
Northern Spain received a real-world installation of an upgraded floating buoy off its coast.
The massive device is stationed at the Biscay Marine Energy Platform and was successfully connected to the electrical grid.
The captured wave energy is transmitted directly to land with an advanced subsea cable.
It is a historic milestone proving that marine infrastructure can supply continuous, baseload clean power.
Harnessing the powerful waves of the ocean is now a practical way to diversify global green energy portfolios.
