El global interest in wave energy It has gained momentum in recent years, driven by the need to diversify the energy mix and move toward a sustainable model that reduces polluting emissions. As the focus on marine renewable energy grows, technological solutions and environmental sustainability become essential elements for its implementation.
Numerous projects, both in Europe and Latin America, are setting the pace of innovation in this field thanks to new technologies and close collaboration between administrations, companies, and research centers. Wave energy, based on harnessing the natural movement of waves, is emerging as a promising alternative to addressing global challenges.
Technological boost on the Basque coast
The Basque region has established itself as one of the most active hubs in the development of wave power devices. The Mutriku wave plant, a pioneer in wave-based power generation, continues to operate as a symbol and testing laboratory on the shores of the Cantabrian Sea. This year, the Basque coast will see the arrival of new prototypes, including an evolved design from the company. Idom and the Keto system of Carnegie Clean Energy, an Australian company that has chosen Bilbao as its base of operations in Europe.
The device Class, designed for submerged installation in the Bimep experimental area (Armintza), is a buoy anchored to the seabed whose orbital movement underwater activates internal mechanisms to convert wave energy into electricityThis electricity is transferred directly to the grid via submarine cables, with almost no visual impact.
These essays are part of the EuropeWave program, supported by the Basque Government, the Scottish agency, and European marine energy entities. In addition, public funding through initiatives such as Achieve allows that, if the results are positive, the technology can be scaled to a commercial level. Each unit of the Ceto system could reach a power of 1 MW, and the goal is to install sets of devices to add relevant capabilities.
Experimentation and potential in Latin America
The development of wave energy is not limited to Europe. In Argentina, the first national prototype seeks to transform the movement of the sea into a constant source of electricity. state support and public investment, the north of Mar del Plata is the scene of the construction of a converter designed by the National Technological University. The system uses floating naval steel buoys These buoys capture the motion of the waves and transform it into electrical energy using a series of gears. Each buoy can provide power ranging from 30 to 200 kW.
Among the advantages of the Argentine model stands out its predictability and high energy density: Wave energy can be up to 30 times greater than that produced by solar energy under similar conditions, making it a particularly interesting resource for the country's future energy mix.
New European models and sustainability
Within the European panorama, other companies such as Seaturns They are betting on innovative solutions: their device uses a water pendulum principle to harness the waves and convert them into electricity. This technology has been tested in real marine conditions for months and demonstrates a good relationship between technical feasibility and efficiency.
The institutional support of programs such as Horizon Europe and collaborations with testing centers, together with the ease of installation and low operating costs These types of systems are driving the transition from the experimental phase to industrial production. In the coming years, technologies like Seaturns' are expected to make a decisive contribution to the diversification of Europe's energy supply, especially in coastal environments.
Compatibility between marine energy and biodiversity
The growth of wave energy must be addressed with a maritime spatial planning that avoids conflicts with the protection of the marine environment. The challenge is Integrating the expansion of marine renewables with biodiversity conservation, at a time when international commitments exist, such as the Kunming-Montreal Agreement, which calls for protecting at least 30% of ocean surfaces by 2030.
Sustainable coexistence requires collaboration between governments, scientists, industry, and coastal communities. Only smart management will allow us to take advantage of the enormous energy potential of the sea without compromising its ecological values or the services it provides to society.
The development of wave energy is experiencing a pivotal moment, with landmark projects in Europe and Latin America and an increasingly clear commitment to sustainability. If the technological and environmental conservation challenges are met, this renewable source can play a prominent role in the new global energy landscape.
