Pioneering battery-backed wind energy for a smooth transition to renewables

Distributed generation for worksites and microgrids currently relies on diesel for energy production—a costly, polluting, and supply-challenged solution. Faced with these drawbacks, the need to integrate renewables is on the rise. Kitepower systems, distinguished by their minimal material usage, offer enhanced mobility and resilience and, when paired with a battery, unlock their full potential.

Kitepower delivers portable wind energy that can be effortlessly transported and installed whilst demanding minimal ground space (m2). The Hawk Battery Energy Storage System seamlessly integrates into established microgrids, powers worksites, and serves remote areas. When the battery is depleted, the kite is launched to charge it. This innovative system is not just revolutionising wind energy; it is reshaping the conventional battery market with battery energy storage systems that are charged on site with renewable power.

The System Components

What does a Kitepower system consist of?

1. Battery

An integrated battery augments energy stability by storing surplus power during peak generation, ensuring a consistent and reliable energy supply.

  • 2.99 m x 2.44 m x 2.59 m
  • 7,5 t
  • 330 kW
  • 400 kWh
  • 100% Lithium-ion (NMC811)
  • IP65
  • 10 years

2. Ground Station (GS)

Converts the mechanical energy of the kite into electrical power and reels the kite in by using the generator as a motor.

  • 2.44 m x 2.60 m x 6.06 m
  • 9.6 t
  • IP64
  • 25 years
  • 400 V AC 3 phase
  • 550-700 V

3. Tether

A Dyneema® line is used for a lightweight and strong connection between the kite and the GS.

  • UHMWPE Dyneema®
  • 352 m

4. Kite Control Unit (KCU)

Controls the roll, pitch, and yaw of the kite and takes care of the communications between the sensor unit placed on the kite and the GS.

  • t
  • 2 km
  • IP65

5. Kite

Consists of a hybrid between an inflatable and a fixed fibre-glass skeleton, forming the best combination for a strong and lightweight wing.

  • 40-60 m²
  • 47 m²
  • 2,5 t
  • 110 km/h

It all fits in a 20ft. ISO container!

System Configuration

Learn more about the Hawk's multiple applications

Kitepower’s Hawk system can be applied in a variety of circumstances. The system can be a replacement for alternative fuel generators at construction sites or in the field of agriculture.

The Hawk can also be applied for remote, off-grid areas with a temporary power demand. The mobile and temporary character of the system benefits a quick, temporary deployment at a variety of locations.

The Power Output

Understanding the Hawk's power cycle
Generation phases vs power output

The electricity generation works in two phases, which repeated in continuous cycles result in positive net energy output. The energy generated by the system while reeling out is greater than the energy consumed to reel the kite back in.

Generation phases vs power output

The electricity generation works in two phases, 1) reel-out and 2) reel-in, which repeated in continuous cycles result in positive net energy output. The energy generated by the system while reeling out is greater than the energy consumed to reel the kite back in.

The Kitepower Hawk:

  • Has a single cycle duration of 100 seconds
  • Produces 40 kW 80% of the cycle’s time when in reel-out
  • Consumes 10 kW 20% of the cycle’s time when in reel-in
Start generating electricity at lower wind speeds

Kitepower represents an innovative and cost-effective alternative to existing wind turbines. Kitepower systems start producing energy with lower wind speeds than the ones required by conventional wind turbines, moreover, Kitepower is capable to harness stronger and more persistent winds at higher altitudes.
