Wind power often evokes images of towering windmills with spinning blades turning kinetic energy into electricity. Yet there are cleaner, more portable ways to harness the wind, such as kites. This approach, though it might resemble a simple children’s game, is central to the energy transition. Kitepower, a Dutch company, has developed a mobile system to capture and store wind energy using tethered kites.
The company’s solution is remarkably straightforward. A kite is attached to a container packed with batteries, enabling direct energy storage for later use. The whole setup is portable and designed for versatile deployment.
Energy for 150 households
Today, the air wind power system can generate about 100 kWh, a figure comparable to what large wind farms achieved thirty years ago. This output could power around 150 homes. The current price sits near €180,000, indicating room for cost improvements as the technology matures.
One of the company’s kites in action
Hawk, Kitepower is emerging as a practical way to supply clean electricity to construction sites, farms, and even remote island communities. Kite power solutions aim to replace diesel generators with highly automated, kite-charged battery energy storage systems (BESS).
How does the system work? Josep Breuer, the company’s CEO, explained to the Dutch outlet mtsprout: a kite takes off and flies in a figure eight, creating a pulling force on the tether. That force is converted into rotational motion by a ground winch, and then transformed into electricity with a dynamo and generator. The result is a compact, efficient energy source that can operate day and night.
According to Breuer, the Kitepower Hawk is easy to install and can deliver power around the clock. Unlike traditional wind turbines, which can face ecological concerns and frequent blade stops, Kitepower’s approach avoids many of these drawbacks. The system is described as less conspicuous from the ground due to its height, and early assessments by the Technical University of Delft suggested minimal disruption to nearby residents.
Flight at 350 meters altitude
The higher altitude offers a clear advantage over conventional turbines. Breuer notes that if surface wind is weak, the system can still generate energy up high, where steady winds prevail. The kite length currently reaches about 350 meters, with the ideal target around 800 meters for optimal wind consistency.
Ground station equipment supports on-site charging while the kite performs long-duration energy collection. On-site battery charging highlights how renewables can power electric vehicles at work sites without relying on distant grids.
Once deployed, traditional wind turbines produce energy with a life-cycle footprint that includes substantial steel, concrete, and transport emissions. Kitepower claims its solution uses 90 to 95 percent less material than comparable wind turbines. Breuer argues that this reduces CO2 emissions per kilowatt-hour and lowers maintenance costs due to longer lifespans and simpler repairs.
Another notable benefit is mobility. The entire system fits within a six-meter shipping container, allowing the kite to be released and lowered as needed. This feature is particularly useful in regions prone to hurricanes or other extreme weather, where rapid redeployment is important.
Security and regulatory compliance are integral. Aerial wind power systems fall under drone-style oversight, and Kitepower maintains a testing facility in Goeree-Overflakkee with plans for extended trials in Ireland to demonstrate safety and performance reliability.
For those seeking further information about environmental considerations and regulatory frameworks, sources continue to explore how kite-based energy aligns with existing aviation and energy policies. Independent assessments emphasize the importance of safe operation, environmental compatibility, and transparent performance data across different climates and terrains.
Notes on environmental aims and deployment strategies continue to evolve as pilots expand into new markets and communities, reinforcing the idea that wind energy can be delivered with lower material demands and adaptable infrastructure. The overarching message remains clear: kite-based wind energy offers a portable, potentially lower-emission pathway to power needs on construction sites, rural areas, and small-scale grids.
End-user and stakeholder inquiries typically focus on safety, regulatory compliance, and long-term performance. To address these concerns, ongoing demonstrations and independent evaluations are essential to validate the technology’s resilience and scalability across diverse environments.

Environmental and industry observers emphasize that kite-based systems represent an evolving frontier in renewable energy, with ongoing trials and pilot deployments shaping practical adoption. For more context, researchers and practitioners point to comparative life-cycle analyses, which examine material use, manufacturing footprints, and the relative emissions associated with different wind technologies. These analyses support a nuanced view of how lightweight, mobile solutions can complement larger wind farms rather than replace them outright.
For further information, inquiries are typically directed to the company’s environmental department and the broader energy transition research community, where ongoing sources offer insight into performance, safety, and environmental impact .
