Innovative Underwater ‘Kites’ Harness Tidal Power in the Faroe Islands

In the rugged and remote Faroe Islands, nestled in the North Atlantic, a groundbreaking project is harnessing the power of tidal currents to generate electricity. Swedish marine energy firm Minesto has developed a tidal kite, dubbed “dragons”, that operates beneath the sea’s surface, designed to “fly” through water currents. This innovative technology, which significantly differs from traditional tidal power methods, aims to revolutionize how tidal energy is captured and utilized. With a 12-meter wingspan and the ability to generate 1.2 megawatts of power, these kites offer a promising alternative energy source that is both maintenance-friendly and capable of operating in low-flow currents.

• The Faroe Islands are using tidal kites designed by Swedish firm Minesto to generate electricity from sea currents.
• These “dragons” have a 12-meter wingspan and weigh 28 tons, capable of delivering 1.2 megawatts of power by moving in a figure-eight pattern underwater.
• The design allows for operation in low-flow currents with lightweight machines, making it distinct from traditional tidal power technologies.
• Maintenance is simplified by designing the system to easily tow in, replace modules, and minimize components, reducing potential damage and costs.
• Tidal energy, driven by the gravitational pull of the moon and sun, offers a predictable and weather-independent power source compared to wind, solar, or hydro power.
• The technology aims to overcome barriers faced by tidal power, such as high costs and ecological impacts, by introducing more efficient and eco-friendly solutions.
• Faroe Islands aim to be self-sufficient in energy, integrating tidal energy with wind, hydro, and solar power, supported by the largest battery storage in the Danish Kingdom to maintain power stability.
• Tidal energy’s predictability could significantly contribute to the islands’ energy mix, potentially providing 30 to 40% of annual energy needs.
• The project represents a significant step forward in utilizing ocean energy, opening up new markets and opportunities for renewable energy sources worldwide.
