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.
