Harnessing Ocean Energy: Inaugural Underwater Tidal Kite Powers Gridh
A novel method of extracting renewable energy from the oceans has recently emerged, drawing attention to its innovative approach. This method, inspired by the movement of a kite, efficiently harnesses energy from tidal and ocean currents and is already contributing electricity to the grid in the Faroe Islands.
The Design and Operational Mechanism
Developed by the Swedish company Minesto, the power generator known as the Dragon 12 utilizes marine energy technology. Despite its substantial size, with a wingspan of 12 meters and weighing 28 tons, the Dragon 12 is adept at maneuvering underwater. It operates within a narrow channel between the islands, tethered to the sea floor to capture energy from tidal currents.
The unique shape of the tidal kite enables it to perform repetitive figure-of-eight movements, maximizing the water flow around the device. This flow, in turn, drives a turbine that generates electricity. The generated power is transmitted through the rope and conveyed to the shore via cables across the sea floor. With a rating of 1.2 megawatts, the Dragon 12 has the potential to meet the energy needs of approximately 1,000 homes.
Milestone Achievement
Minesto’s successful electricity production to the grid marks a significant milestone in the company’s history. Dr. Martin Edlund, CEO of Minesto, expressed pride and optimism about the prospects of the technology, highlighting its potential to revolutionize renewable energy production globally.
The Minesto tidal power generation system offers a promising, cost-effective solution compared to traditional tidal projects and offshore wind turbines. Its ease of deployment and the predictability of tidal currents make it a compelling alternative for renewable energy generation, potentially rivaling offshore wind generation in cost-effectiveness.
Future Outlook
As the technology continues to evolve and scale, it promises to become a competitive and sustainable renewable energy source. Its simplicity of deployment and reliability in harnessing tidal currents make it a frontrunner in the renewable energy landscape, sparking anticipation for its further development and adoption worldwide.
