Exploring soaring heights for renewable energy: Harnessing wind power in Ireland
The Dutch firm Kitepower is revolutionising the renewable energy sector with its innovative airborne wind energy (AWE) system. The kite power project is currently generating renewable electricity in Bangor, Ireland, marking a significant step towards a sustainable future.
The kite system, which can be set up in just 24 hours, is highly mobile and suitable for remote, offshore, or mobile applications. Kitepower's system uses tethered kites flying at altitudes up to ~350-400 m to harness stronger, more consistent high-altitude winds, enabling higher capacity factors than conventional turbines.
Unlike traditional wind turbines, Kitepower's system requires minimal infrastructure, occupying a small ground footprint (~6 × 2.5 m). The kite, 60 square meters in size, flies up to 400 meters and reels in to about 190 meters, generating around 30 kilowatts of power. The electricity generated is stored in batteries, capable of fully charging a 336 kWh battery.
During Storm Eowyn in Ireland, the kite system provided uninterrupted electricity before, during, and after the storm, demonstrating its reliability and practical viability for remote and offshore use. The system's energy production is sufficient for powering a remote outpost, a small island, or even a construction site.
Kitepower's approach trades off absolute peak power for flexibility, mobility, faster installation, and access to stronger high-altitude winds, making it a complementary or alternative renewable energy source in niche applications where conventional turbines are not optimal.
Ireland's wind energy sector has ambitious targets for offshore wind energy, aiming to deliver 20 gigawatts by 2040 and at least 37 gigawatts by 2050. With Kitepower's system, additional kites could be used to power a bigger island, contributing to these targets.
The kite system does not require expensive, time-consuming turbine foundations, making it a cost-effective solution for remote and offshore power needs. AWE researcher Mahdi Salari expects AWE to contribute meaningfully to diversified, flexible, and distributed renewable energy networks by the 2030s.
Despite its advantages, Kitepower may face challenges in regulation, safety, and system reliability. However, the potential benefits of AWE systems in providing clean energy without needing a supply chain of fuel make it an exciting development in the renewable energy sector. The site in Bangor, Ireland, is the world's first designated airborne renewable energy test site, paving the way for further research and development in this promising technology.

- The kite system developed by Dutch firm Kitepower, which currently operates in Bangor, Ireland, is not just revolutionizing the renewable energy sector, but also opening opportunities in sport, technology, and news, as its mobility and high-altitude wind energy harnessing capabilities make it suitable for various applications, including remote islands and offshore sites.
- According to researcher Mahdi Salari, the airborne wind energy (AWE) technology, like the one used by Kitepower, has the potential to contribute significantly to diversified, flexible, and distributed renewable energy networks by the 2030s, impacting the world's pursuit of science and sustainability.
- Artistically, the kite system's unique design and operation could inspire a new generation of technological and environmental art pieces, adding an aesthetic dimension to the future of renewable energy.
- In the realm of east-west global energy dialogues, the success of projects like Kitepower's could foster collaborations and knowledge sharing, promoting a more interconnected and sustainable world.
