This underwater “kite” transforms the tides into electricity to power thousands of homes!
The world of renewable energy is witnessing the emergence of a major innovation with the Dragon 12, an underwater kite-like device that harnesses the power of the tides to produce electricity. Installed in the waters of the Faroe Islands, this 28-ton giant is not only a technological feat but also a giant step towards more accessible and economical sustainable energy. Here's an in-depth exploration of this promising technology and its potential implications for our energy future.

An underwater kite to capture tidal energy
The Dragon 12, developed by the Minesto company, stands out for its unique approach to capturing tidal energy. Unlike conventional turbines which capture energy directly from sea currents, the Dragon 12 is anchored to the seabed and moves like a kite in the currents, allowing it to exploit tides more dynamically and efficiently.
An optimized design for maximum performance
This innovative system uses 12 meter wingspan to fly in figure eights underwater, thereby accelerating its speed relative to the sea current and increasing its ability to generate energy. This method allows the Dragon 12 to produce more energy by current than existing technologies, making even slower ocean currents economically exploitable.
Simple installation and reduced operating cost
Compared to large offshore wind turbines, the Dragon 12 is relatively small and much simpler to install. It can be deployed using a small boat and a seabed mooring, thus simplifying the process and reducing installation and maintenance costs.
Promising economic efficiency
The cost of energy generated by the Dragon 12, called LCoE (levelized cost of energy), is competitive. Initially projected at around €104/MWh, this cost should drop to 52 euros/MWh with the increase in installed capacity, making this technology very attractive compared to other forms of renewable energy.
An ideal location in the Faroe Islands
Faroe Islands offer ideal conditions for this technology thanks to their narrow channels which accelerate marine currents, thus increasing the energy potential exploitable by the Dragbon 12. This site not only maximizes energy efficiency but also demonstrates the adaptability of this technology to different marine environments.
A significant impact on the local electricity network
The energy produced by Dragon 12 is already connected to the local power grid, providing a stable and predictable source of renewable energy to the Faroe Islands community. This marks an important step in the energy transition from the region towards greener and more sustainable sources.
A promising future for tidal energy
The success of Dragon 12 could serve as a model for other similar projects around the world, particularly in regions where marine conditions are favorable. This could help diversify available renewable energy sources and reduce dependence on fossil fuels.
This colossal 2 billion euro market risks collapsing in the face of the first portable hydraulic turbine, a phenomenal innovation that redefines energy autonomy
This article explores the rise of the Dragon 12, an underwater kite-like device that is revolutionizing tidal power generation. By exploiting the tides in an innovative way, this system offers a renewable and economical solution for electricity production. With its simplified installation and competitive cost, the Dragon 12 could well be the key to a cleaner and more sustainable energy future.
