Harnessing Tides: The Groundbreaking Space Program to Unlock Renewable Energy
Since its inception in 1907, SKF has been at the forefront of manufacturing some of the world's most innovative solutions in bearings, seals, lubrication systems, and condition monitoring technologies aimed at reducing friction. Now, in a visionary partnership with Minesto, a pioneering force in marine energy development, SKF is embarking on an unprecedented 'space program' designed to harness tidal energy through the gravitational pull of the moon.
This unique initiative, which is firmly rooted on Earth, aims to tap into the abundant renewable resources our planet offers. The Faroe Islands, with one of the most ambitious energy transition agendas, seeks to transition 100% to renewable energy by 2030, making it an ideal location for this endeavor.
At the core of the project is an innovative tidal kite system named Luna. Unlike traditional spacecraft that venture into the cosmos, Luna operates underwater, harvesting energy from the tides invisibly and silently. This system is powered by the moon's gravitational influence and operates independently of local weather conditions. Martin Edlund, CEO of Minesto, describes the collaboration with SKF as an inspiring and educational experience, stating that there could potentially be at least 3,000 regions worldwide akin to the Faroe Islands that could benefit from this program.
The implication of this technology is immense. With Luna's rated power of 12 MW, it has the capacity to provide electricity for 200 homes for an entire year. Looking ahead, Minesto aims to establish a tidal energy plant generating 200 MW, which could meet 40 percent of the expected electricity demands by 2030 for the small, remote island nation of approximately 50,000 inhabitants and 70,000 sheep.
This ambitious undertaking benefits from the expertise of local electricity provider Sev, whose CEO, Hákun Djurhuus, emphasizes the importance of tidal power in achieving the vision of 100% renewable electricity production. He explains that working collaboratively across industry lines, as demonstrated between SKF and Minesto, is vital for the continuous evolution toward sustainable energy solutions.
SKF's engineering proficiency is crucial, with its design of bearing and sealing systems for the kites’ rudders and elevators. Additionally, SKF's software solutions contribute to lifecycle assessments of these components and estimate CO2 emissions, allowing for a thorough comparison of different energy solutions from both a technical and sustainability standpoint.
Annika Ölme, Technical Director of the SKF Group, highlights that collaboration across sectors can accelerate the transition to renewable energy. By framing this initiative as a 'space program' that remains tied to Earth, the partners seek to inspire a shift in mindset regarding the utilization of our planet’s resources.
Current statistics show that 80% of global electricity consumption relies on fossil fuels; however, by 2050, marine energy could play a pivotal role in the energy mix. Tidal energy is both local and renewable, making it a complementary technology to established renewable sources like wind and solar. According to forecasts from Ocean Energy Europe, marine energy has the potential to deliver 10% of Europe’s electricity, while also generating 400,000 specialized jobs by 2050.
In summary, the collaborative efforts of SKF, Minesto, and local stakeholders in harnessing tidal energy represent a significant movement towards a sustainable energy future. The moon’s gravitational forces, combined with innovative technology, could transform energy production as we know it, ushering in a new era of green electricity.
