ENGIE and SkySails Power GmbH are leading the way in harnessing high-altitude wind power with groundbreaking renewable energy generation technology. The companies have now consolidated a collaboration on two international pilot projects.

Within this collaboration, ENGIE has acquired two innovative airborne wind energy (AWE) systems in the form of SkySails wind-kites, each capable of generating up to 200 kW of power. The two pilot projects will not only serve as real testing grounds for the airborne technology but will also integrate it into comprehensive hybrid renewable energy and storage systems enabling the exploration of multi-renewable energy source interactions and grid compatibility. ENGIE, with the assistance of ENGIE Laborelec, will diligently operate and assess the SkySails Power System as part of the pilot projects to evaluate and confirm its technological capabilities. Following successful completion of the pilot phases, both companies intend to further expand their collaboration to encompass additional locations and delve into wind farm applications.

The first project, named “Aquilon,” is situated at the ENGIE company Storengy Deutschland GmbH site in Peckensen, Germany. It will utilise Skysails’ innovative kite airborne technology in conjunction with solar photovoltaics and an advanced redox flow battery with the goal of managing energy and power within this hybrid system; making best use of clean energy technologies to avoid 100% greenhouse gas emissions at an industrial site.

The second pilot project will concentrate on taking clean energy to remote or isolated areas like islands, where access to energy is crucial for populations reliant on fossil fuels for power. Scaling up such a project for thousands of inhabitants, incorporating biomass, solar, wind, AWE technology, and storage, presents a challenge that must be addressed to pave the way for new market solutions aimed at achieving 100% renewable energy on islands.

Daniel Mercer, Head of business development at Storengy Deutschland GmbH, says: The airborne technology, which ENGIE has eagerly supported and implemented due to its significant potential, is part of this innovative hybrid project pushing for the integration of multiple energy technologies. This initiative not only aims to validate the feasibility of each technology but also to explore their synergistic interactions, and the emerging technology has the potential to be deployed in nearly any location, making it an ideal complement to existing renewable technologies.

ENGIE embraces the opportunity to move forward with a technology that has been under observation for the past 11 years, and is currently poised for large scale realisation as AWE technology shows noteworthy potential across a spectrum of uses and dimensions. Its strength being that airborne uses the stronger, more consistent, high-altitude wind resources to more consistently push energy generation further towards carbon neutrality. This seamlessly complements the existing portfolio of renewable technologies by ENGIE. It opens up the perspective to a visionary outlook, spanning across decentralized and expansive onshore projects, while also laying the groundwork for future explorations into offshore airborne wind ventures.

The lightweight and compact design of our airborne wind energy system ensures minimal impact on both people and the environment, making it feasible for installation even in the most remote locations. The systems practically have no visible effect on the landscape and barely cast a shadow”, explains Stephan Wrage, CEO of SkySails Power GmbH. Firmly believing that these benefits can further increase acceptance for more innovative wind energy systems, he adds “This makes our SkySails technology an exciting alternative to traditional renewable power generation.
