Harnessing the Moon's Energy: A Revolutionary Tidal Kite Initiative
Since its inception in 1907, SKF has remained at the forefront of innovations in bearings, seals, lubrication systems, and condition monitoring solutions aimed at reducing friction across a multitude of industries. In a groundbreaking collaboration with Minesto, a leader in marine energy, SKF is now embarking on a unique project that could transform our approach to renewable energy: a space program focused on harnessing the power of the moon's gravitational pull through tidal energy.
This ambitious project is based in the Faroe Islands, which has pledged to become 100% renewable by 2030. Far from reaching for the stars, this initiative seeks to utilize the abundant resources present on Earth, particularly the underwater currents driven by the moon’s influence.
The innovative technology at the heart of this initiative is Minesto’s tidal kite, aptly named Luna. This kite operates at depth, silently harnessing energy from tidal currents without disturbing marine ecosystems or surface activities. After its initial successful sea launch, Luna has demonstrated the potential to generate predictable renewable energy regardless of weather conditions. Martin Edlund, CEO of Minesto, remarked, "For us, as a technology development company working with a global company like SKF, it is both an educational experience and an inspiration. We estimate that there are at least 3,000 more Faroe Islands out there that qualify for our space program; if they all join, lunar energy could replace all coal power capacity currently being developed globally."
The energy generated by Luna is substantial; its nominal output of 12 MW is sufficient to power approximately 200 villas for a year. Minesto is looking ahead to expand its operations by establishing a new tidal energy facility with a capacity of 200 MW. This facility could meet nearly 40% of the electrical needs expected by 2030 for the small island community, which comprises around 50,000 residents and 70,000 sheep, moving toward a greener future.
Minesto’s collaboration with the local utility firm, Sev, is vital for the success of this project. "Our vision is to achieve 100 percent renewable electricity production by 2030, and we believe tidal power can prove to be an essential part of this journey," stated Hákun Djurhuus, CEO of Sev.
Collaboration across industries is essential for driving forward the energy transition. SKF has designed the advanced bearing and sealing systems for the kites’ rudders and elevators. Its innovative software also calculates the lifespan of these components and estimates CO2 emissions from various energy solutions. This allows for comprehensive evaluations that consider both technical viability and sustainability.
Annika Ölme, the technology director at SKF, emphasized the significance of this partnership and the necessity of such collaborations in fostering technological and innovative advancements for renewable energy. By framing the project as a space program that remains Earth-bound, SKF and Minesto reinforce the message of utilizing our existing planetary resources to address energy needs.
According to the International Energy Agency, a staggering 80% of the global electricity is still derived from fossil fuels. However, by 2050, marine energy has the potential to constitute a considerable portion of the energy mix, potentially supplying up to 10% of Europe's electricity needs and creating around 400,000 jobs, as projected by Ocean Energy Europe.
This pioneering initiative in the Faroe Islands epitomizes the future of clean energy, demonstrating how imagination and innovation can join forces to reframe our energy landscape, making it more sustainable and reliant on the natural forces we have at our disposal. As we await the results of Luna’s endeavors, one thing is certain: the tides of change in renewable energy are rising.
