The world's demand for safe and clean energy continues to grow, with renewable sources playing an every greater role. Wind power generation, having expanding offshore, is now not only looking out but up. International renewable energy consultancy, GL Garrad Hassan, has issued the first market report which analyses the burgeoning new industry of High Altitude Wind Energy (HAWE).
HAWE systems are designed to tap into the high velocity, stable air currents that exist at altitudes anywhere from 200m to 20 km above the earth; a source for generating cheaper and more abundant electricity than current wind technology.
The report looks at the potential of high altitude winds as an energy source, the current technologies within the sector and their potential as mature systems. As well as assessing individual technologies and the companies developing them, the report addresses the technical and regulatory challenges faced by the industry and the likelihood of its success.
As this emerging industry has grown, a cottage like mentality with small entrepreneurs and inventors has flourished, with a diverse array of systems types at various stages of development. Small and real scale prototypes from many developers are currently in active development. The report identifies 22 companies that have already developed, or have announced their intention to develop, prototypes including: kites, kytoons and aerostats, and gliders or sailplanes with turbines or airfoils attached.
In Europe and America, these developers are beginning to see an influx of investment from both private and governmental partners and the report looks at the potential for investor involvement at the nascent stages of this industry.
The system might take the form of a kite, a parachute, or a rotating balloon, or a fixed wing, be tethered in parallel, on a floating platform offshore. GL Garrad Hassan's report looks at the prototypes, the potential of the major players and the challenges that need to be met for the technology to flourish.
Greater Wind Potential at 200m Plus
This logic underlies the push to build turbines with higher towers. HAWE systems are expected to operate at heights of greater than 200m, with the focus being at altitudes above two kilometres. Data for extreme heights has been limited but GL Garrad Hassan examines the potential resource, the associated energy figures, and analyses the energy potential at altitudes of above 1km.
Challenges facing the systems and the current and possible regulatory environmental are analysed in terms of their future commercial applications; and the political and legal frameworks, across multiple regional energy markets, with the potential to affect high altitude technology application are outlined.

Researchers build a tougher, lighter wind turbine blade
Cleveland OH (SPX) Aug 31, 2011
Efforts to build larger wind turbines able to capture more energy from the air are stymied by the weight of blades. A Case Western Reserve University researcher has built a prototype blade that is substantially lighter and eight times tougher and more durable than currently used blade materials. Marcio Loos, a post-doctoral researcher in the Department of Macromolecular Science and Enginee ... read more
