Harnessing Lunar Waves: The Faroe Islands' Ambitious Tidal Energy Initiative
Since 1907, SKF has been at the forefront of innovation in manufacturing bearings, seals, lubrication systems, and condition monitoring solutions to reduce friction. In an exciting new venture, SKF has collaborated with Minesto, a pioneer in marine energy technology, to embark on a unique 'space program' that aims to harness tidal energy driven by the moon's gravitational pull. This project is designed to remain entirely on Earth, focusing instead on utilizing the natural resources available here.
The Faroe Islands are leading the charge with one of the most ambitious energy transition programs globally, striving to achieve 100% renewable energy by the year 2030. Central to this initiative is a groundbreaking tidal kite, named Luna, developed by Minesto. Unlike traditional methods of harnessing wind or solar energy, the Luna kite operates invisibly and silently beneath the water’s surface, capturing energy from tidal streams. This energy is consistently available, independent of weather conditions, thanks to the moon’s predictable influence on ocean tides.
As Martin Edlund, CEO of Minesto, noted, working alongside a global industrial leader like SKF has been both an educational and inspiring experience. The potential for this technology is substantial, as there are thousands of locations worldwide, akin to the Faroe Islands, that could benefit from such tidal energy solutions. If adopted globally, lunar-powered tidal energy could replace a significant portion of the coal power capacity that's currently in development around the world.
The Luna energy kite boasts a nominal power of 12 MW, sufficient to supply enough electricity for 200 villas for an entire year. Looking forward, Minesto aims to implement a new tidal energy facility capable of generating 200 MW, which could meet 40% of the anticipated electricity demand of the Faroe Islands by 2030. This would provide a sustainable source of energy for the island nation, which is home to about 50,000 people and 70,000 sheep. The local power company, Sev, is also driving this mission, with CEO Hákun Djurhuus emphasizing the critical role tidal energy could play in achieving their 100% renewable energy goal.
Collaboration across different industries is crucial for the success of this initiative. SKF has been integral in designing the bearings and sealing systems for the tidal kites’ components, such as the rudder and elevators. They also provide advanced software to analyze the lifecycle of these bearings and assess CO2 emissions. This comprehensive approach allows comparisons of various solutions from both technical and sustainability perspectives.
Annika Ölme, the Chief Technology Officer of the SKF Group, highlighted how this partnership exemplifies the power of technology and innovation in driving the transition to renewable energy. By framing this initiative as a 'space program' that never leaves Earth, the collaborators underscore the importance of leveraging the resources available on our planet and developing sustainable energy solutions.
The significance of tidal and marine energy is increasingly recognized, especially considering that, as reported by the International Energy Agency, 80% of global electricity is currently derived from fossil fuels. Projections suggest that marine energy could contribute substantially to the energy mix by 2050. With its local and renewable characteristics, tidal energy presents a reliable complement to more traditional renewable sources like wind and solar power. According to Ocean Energy Europe, marine energy could meet up to 10% of Europe's electricity needs and potentially create 400,000 qualified jobs by 2050.
Overall, the lunar tidal energy project spearheaded by SKF and Minesto embodies a forward-thinking approach to energy production, harnessing the natural forces that surround us to forge a path toward a sustainable and renewable future.
