Portugal advances wave energy push with 1-MW offshore power site
Portugal is advancing its wave energy initiatives with a planned one-megawatt (MW) wave energy installation on the northern coast, specifically at the Barra do Douro breakwater in Porto. Swedish developer Eco Wave Power Global Ab., in collaboration with Rotterdam-based MetOcean Consult, completed a detailed wave and structural load assessment confirming favorable ocean conditions for the project. The company submitted the full execution plan to the Port Authority of the Douro, Leixões and Viana do Castelo (APDL) in January 2026, marking a formal step toward construction and scheduling. This installation is set to be the first megawatt-scale project under Eco Wave Power’s 20-MW concession agreement with APDL, representing a significant milestone in their broader wave energy rollout. The Porto project is designed to integrate wave energy equipment directly into the existing breakwater structure, known locally as “The Gallery,” which helps reduce environmental impact, simplify maintenance, and lower costs. Key milestones already achieved include payment of 50

The article discusses SEA-Stack, an innovative, free, open-source modeling tool designed to help developers rapidly assess and optimize floating wave energy technologies and other water-based devices. SEA-Stack integrates multiple wave energy modeling capabilities into a single, user-friendly platform, enabling quick simulations ranging from simple design assessments to complex analyses that incorporate intricate ocean physics. Leveraging high-performance computing and machine learning, SEA-Stack is significantly faster—10 to 100 times—than previous tools and can process the latest wave energy data, making it a versatile "Swiss Army knife" for wave energy developers and related marine technology fields. Wave energy devices have strong potential to contribute to a secure and resilient power system by harnessing predictable ocean wave energy, but they face significant engineering challenges due to the harsh ocean environment. Traditional testing methods are costly and risky, as prototypes can fail or underperform when exposed to real ocean conditions. Existing modeling tools are limited in their ability to simulate critical features such as flexible device components, collisions, and

Dutch company Symphony Wave Power has successfully completed dry testing of its innovative underwater wave energy converter, marking a significant milestone ahead of its planned 2026 deployment in the North Sea. The system is a fully submerged point absorber that harnesses wave-induced pressure variations to generate renewable electricity. Unlike traditional surface buoys, it operates invisibly beneath the sea surface, using a fixed seabed-anchored core and a vertically moving hull separated by a flexible liquid- and air-filled membrane. Wave motion forces liquid through a bidirectional turbine connected to a generator, producing clean, stable power that can feed directly into an underwater DC grid. The technology boasts up to 500% higher efficiency than conventional non-resonant designs by tuning its internal spring to resonate with wave frequencies, maximizing energy capture. It is designed to be simple, sustainable, and low-impact, with only two moving parts made from recyclable materials, and requires minimal installation effort and maintenance. Clusters of up to 60 units can generate as much as

Canadian cleantech company Voltai has secured over USD 1.3 million (CAD 1.83 million) in an oversubscribed pre-seed funding round led by Invest Nova Scotia and supported by angel investors, including Mahir Sahin. Voltai is developing an innovative, compact, top-like electrostatic wave energy converter that harnesses kinetic energy from ocean waves and ship movements to generate clean electricity. Unlike traditional bulky wave energy systems, Voltai’s device can be installed directly on vessels and offshore structures without causing drag or performance loss. The technology aims to provide continuous, maintenance-friendly onboard power, helping the maritime industry reduce fossil fuel dependence and lower CO2 emissions. The company is currently scaling its prototype from 25 watts to 100 watts, with plans to bundle ten units into a one-kilowatt system suitable for marine and mobile applications such as powering vessels, navigation systems, coastal infrastructure, and research stations. Voltai’s unique energy conversion mechanism promises efficient and cost-effective wave energy

Eco Wave Power, an Israeli company, has completed operational testing of its Energy Conversion Unit (ECU) in a pilot project at the Port of Los Angeles. The system uses floating blue paddles—resembling piano keys—attached to a concrete pier to harness the up-and-down motion of ocean waves. This movement activates hydraulic pistons that push fluid through pipes, spinning a turbine to generate clean electricity. The pilot involves eight wave energy floaters connected to the ECU housed in shipping containers. If successful, the company plans to expand the installation along the 13-kilometer breakwater protecting the port, potentially supplying power to 60,000 U.S. households. Wave energy offers a reliable and renewable power source, as ocean waves are constant compared to solar or wind energy. The U.S. Department of Energy estimates that waves off the West Coast could theoretically power 130 million homes, about one-third of the nation’s electricity needs. Eco Wave Power’s dock-mounted, retractable design addresses previous

French startup Seaturns has secured $2.9 million in funding to advance and industrialize its innovative wave energy technology, aimed at converting ocean wave motion into reliable electricity. The Bordeaux-based company plans to deploy a full-scale demonstrator at the SEM-REV offshore test site in summer 2025, initiate industrial-scale production, and expand its commercialization globally. The funding round, led by the climate tech platform Keenest and supported by over 1,500 individual investors and institutional backers, will accelerate Seaturns’ efforts to bring its patented, cost-efficient wave energy converter (WEC) to market. Seaturns’ technology features a cylindrical WEC that harnesses the horizontal surge motion of ocean swells, converting it into a pitching motion via a patented anchoring system. Inside the converter, a water pendulum and two air chambers generate airflow that drives a turbine connected to a generator, producing electricity. The device is designed for simplified offshore installation, low maintenance, and reduced environmental impact

A pioneering French collaboration has initiated the construction of Dikwe, the first full-scale energy-positive breakwater system in Boulogne-sur-Mer, northern France. Developed jointly by French marine research institute Ifremer and technology company GEPS Techno, with construction by the UK-based Legendre Group, Dikwe integrates wave energy generation into traditional harbor breakwaters. Unlike conventional breakwaters that solely protect coastlines and harbor vessels from waves and erosion, Dikwe incorporates oscillating flaps connected to energy capture devices that convert wave motion into electricity, offering a low-carbon, renewable energy source that addresses intermittency issues common in wind and solar power. The concept originated at Ifremer and has been refined over more than a decade, progressing from small-scale prototypes tested in controlled wave facilities to a 1/4th scale model tested in 2022. Following successful trials, Legendre Group and GEPS Techno formed a joint venture, Wave-Op, to promote the deployment of Dikwe technology and
