Harnessing Tidal Energy: The Innovative Space Program That Stays on Earth
Since 1907, SKF has been at the forefront of innovation in bearings, seals, lubrication systems, and condition monitoring solutions, working diligently to reduce friction in machinery and equipment. Now, in a groundbreaking collaboration with Minesto, a leader in marine energy, SKF is unveiling an ambitious project that aims to harness energy from the tidal forces generated by the moon. Unlike traditional space programs that seek to explore beyond our planet, this initiative focuses on optimizing Earth's existing resources.
The Faroe Islands, known for their commitment to sustainability, aim to achieve 100% renewable energy by 2030. To support this goal, the innovative tidal kite, named Luna, will operate underwater, effectively capturing energy from daily tidal currents without any noise or visible impact on the environment. This revolutionary technology leverages the moon's gravitational pull to create predictable and renewable energy, irrespective of weather conditions.
According to Martin Edlund, CEO of Minesto, the partnership with SKF is not only educational but also inspirational. He notes that if their project expands to similar regions globally, it could potentially replace all coal power capacity currently under development worldwide. In fact, the energy kite Luna possesses a nominal output of 12 MW, which is sufficient to power 200 villas annually.
As part of its roadmap, Minesto is planning to implement a tidal energy facility with a capacity of 200 MW. This facility could supply up to 40% of the expected electricity needs of the Faroe Islands by 2030, providing green energy to a population of around 50,000 residents and countless sheep. Hákun Djurhuus, CEO of the local electricity company Sev, emphasizes the importance of tidal power in reaching their renewable electricity production goals by 2030.
Collaboration among industry leaders is essential for the advancement of renewable energy technologies. SKF has provided bearing and sealing systems for the kite's rudders and elevators, and has also developed a software system that calculates the lifecycle of these bearings and estimates associated CO2 emissions. This data enables stakeholders to compare technical solutions from both performance and sustainability viewpoints. Annika Ölme, Chief Technology Officer of the SKF Group, highlights how this partnership showcases the potential of technology and innovation to drive the transition toward renewable energy.
The framing of this venture as a 'space program that never leaves Earth' serves to underscore the importance of utilizing local resources. This approach fosters awareness of the benefits of capturing marine energy, which, according to the International Energy Agency, could significantly shift the world's energy landscape. While currently, 80% of global electricity originates from fossil fuels, marine energy has the potential to become a crucial part of the energy mix by 2050, supplying up to 10% of Europe's electricity and generating hundreds of thousands of jobs.
As the world grapples with the urgent need for sustainable energy solutions, initiatives like the tidal kite program signal a promising shift toward renewable energy futures, powered by the moon's influence over Earth's tides.
