Harnessing the Moon's Energy: A New Dawn for Tidal Power
Since 1907, SKF has been at the forefront of manufacturing innovative bearings, seals, lubrication systems, and condition monitoring solutions aimed at reducing friction. In a groundbreaking collaboration with Minesto, a pioneering developer of ocean energy, they are now embarking on an unprecedented "space program" that seeks to harness the moon's energy through tidal power. Unlike traditional space missions, this initiative is focused entirely on utilizing Earth's existing resources.
The Faroe Islands have set an ambitious target of achieving 100% renewable energy by 2030. This project resonates deeply with their vision, as it aligns closely with the urgent need for sustainable energy solutions. This celestial-inspired initiative is aptly named as its tidal kites descend into the ocean depths, capturing energy generated by the gravitational pull of the moon.
Minesto's innovation, the tidal kite Luna, is designed to operate underwater, silently and invisibly, harvesting the renewable energy from tidal currents irrespective of weather conditions. According to Minesto's CEO, Martin Edlund, collaborating with a prominent industrial company like SKF has been both an educational experience and an inspiring partnership. Edlund anticipates the potential of this technology to be replicated across at least 3,000 other locations globally. If these regions embrace moon energy, it could significantly reduce the reliance on coal power worldwide.
The Luna energy kite has a nominal capacity of 12 Megawatts, sufficient to power about 200 households for an entire year. The next ambitious target for Minesto is the construction of a tidal energy facility with a capacity of 200 Megawatts, which is envisioned to fulfill 40% of the predicted electricity needs of the Faroe Islands by 2030. As the island nation, home to 50,000 residents and 70,000 sheep, strives for a greener future, local electric company Sev, led by CEO Hákun Djurhuus, is actively collaborating with Minesto to achieve these sustainable energy goals.
The partnership between SKF and Minesto highlights the essence of interdisciplinary collaboration in driving innovation. SKF has taken charge of creating the bearing and sealing systems vital for the kites’ rudders and elevators. Their advanced software systems also play a crucial role in estimating bearing longevity and analyzing carbon dioxide emissions, allowing for comparisons of various solutions based on technical efficiency and sustainability. As Annika Ölme, the technology director for SKF Group, emphasizes, the joint efforts are crucial in showcasing how technology can steer the transition toward renewable energy.
By framing this initiative as a "space program that never leaves Earth," the stakeholders aim to underscore the significance of exploring and leveraging the moon's energy for renewable energy production. Acknowledging that 80% of global electricity currently derives from fossil fuels, there is a pressing demand for alternative energy sources. According to projections by the International Energy Agency, ocean energy could play a vital role in our energy landscape, potentially contributing significantly by 2050.
Ocean Energy Europe estimates that ocean energy has the potential to provide 10% of Europe’s electricity while creating approximately 400,000 qualified jobs by the year 2050. As the world shifts focus towards sustainable energy, the collaborative efforts of SKF and Minesto serve as a hopeful model in harnessing renewable resources, ensuring that the power of the tides is both visible and effective in transforming the energy landscape. The future is looking bright as we embrace the synergy between earth and celestial energy resources.
