Harnessing the Moon's Power: The Innovative Tidal Kite Project in the Faroe Islands
Since 1907, SKF has established itself at the forefront of innovation in manufacturing bearing, seals, lubrication systems, and condition monitoring solutions. In a groundbreaking collaboration with Minesto, a leader in marine energy development, SKF has launched a unique initiative likened to a space program—but with a focus on harnessing the power of tidal waves here on Earth.
This project aligns with the Faroe Islands' ambitious goal of achieving 100% renewable energy by 2030. It highlights the potential of tidal energy as a significant contributor to the global shift towards sustainable energy sources. Rather than embarking on a journey into space, this initiative aims to utilize earthly resources, specifically the energy generated from tidal movements.
The innovative structure at the heart of this project is the tidal kite named Luna. This underwater device silently glides through the currents, extracting energy from daily tidal flows driven by the moon's gravitational pull, irrespective of the weather conditions. One might think of this technology as a form of renewable energy harvesting that capitalizes on nature's rhythm.
Martin Edlund, CEO of Minesto, reflects on the partnership saying, "For us as a technology development company working with a global industrial company like SKF is both an educational experience and an inspiration." The collaborative effort harbors the potential to expand beyond the Faroe Islands, with estimates suggesting up to 3,000 regions worldwide could benefit from similar programs, indicating a vast global potential to replace coal power with tidal energy.
The energy kite Luna boasts a nominal output of 12 MW, enough to power up to 200 villas for an entire year. Looking ahead, Minesto aims to establish a new tidal energy facility with a capacity of 200 MW, which would meet 40% of the anticipated electricity needs in the Faroe Islands by 2030. This achievement is particularly significant for a small island nation of approximately 50,000 residents and 70,000 sheep. Collaboration with local utility company Sev is pivotal in meeting the region's energy goals.
Hákun Djurhuus, CEO of Sev, shares the vision and emphasizes, "Our vision is to achieve 100% renewable electricity production by 2030, and we believe that tidal power could prove to be an important part of this journey."
SKFs contribution is not limited to partnering on research but extends to designing vital components such as bearing and sealing systems for the kites' rudders and elevators. They provide software systems that assess bearing lifespan and CO2 emissions, enabling comparison of solutions based on both technical and sustainability criteria.
Annika Ölme, technology director for the SKF Group, underscores the importance of cross-industry cooperation, stating, "Together with Minesto, we demonstrate how technology and innovation can drive the transition to renewable energy."
By branding the initiative as a space program that never leaves Earth, the partners highlight the essential notion of leveraging available natural resources for renewable energy production. This innovative approach encourages a fresh perspective on sustainability efforts, focusing on actionable solutions that resonate with environmental problems on our planet.
The International Energy Agency reports that currently 80% of global electricity is sourced from fossil fuels. However, by 2050, marine energy, notably tidal, is projected to comprise a meaningful element of the energy mix. It is reliable, local, and perfectly complements other established renewable sources such as wind and solar.
The potential for marine energy contribution is vast, with estimates from Ocean Energy Europe suggesting it could provide 10% of Europe's electricity and create approximately 400,000 qualified jobs by 2050. The move to embrace marine energy, including projects like Luna, symbolizes a transition that not only addresses energy demand but also fosters economic growth through innovation in renewable energy technology.
