Swedish energy firm's tidal kite achieves 25% power output increase

Swedish ocean energy developer Minesto has achieved a significant milestone with its Dragon 12 (Luna) tidal energy system, deployed in the Vestmannasund area of the Faroe Islands. By extending the tether length by 10 meters, the 25–28 tonne underwater kite with a 12-meter wingspan increased its power output by 25 percent, fully matching performance predictions. This success validates Minesto’s simulation models and supports the commercial viability of its unique subsea kite technology, which generates electricity by flying in a controlled figure-of-eight pattern underwater, propelled by tidal currents. The Dragon 12 system, part of a broader project aiming for a total capacity of 10 MW, has demonstrated technical resilience and operational stability since its grid connection in early 2024. Minesto plans to scale up with an upgraded Dragon 12 model featuring a 1.75 MW generator and improved wing design for the Hestfjord site, forming the foundation for the 10 MW Dragon Farm. This
