Zero emission drone on the horizon

Images of the first unmanned, hydrogen fuel cell powered drone have been unveiled by Wirth Research.

The Unmanned Aerial System (UAS) will be a Tilt Rotor, Vertical Take Off and Landing (VTOL) advanced terrain mapping drone, which will carry a sophisticated suite of terrain-mapping sensors and on-board data processing capabilities. To allow the longest possible endurance with zero in-flight emissions, and reduced vibrations, this unique UAS will be powered by an advanced hybrid power system, featuring a hydrogen fuel cell as its primary energy source. The complete hydrogen fuel cell storage, control and power system will be provided by HES of Singapore, the world’s leading specialist in ultra-light hydrogen fuel cells.

The key advantage of the Wirth Research UAS is the combination of its VTOL capability, allowing it to take off and land in very restricted terrain, and its ultra long endurance.

Wirth Research founder and CEO, Nick Wirth, said, ‘This project continues to present us a fascinating challenge, and it’s great to reveal another key feature of this amazing UAS today. It has been extremely challenging for Wirth Research to meet the requirements of VTOL capability, six-hour mission endurance, packaging a bulky payload mass and providing that payload with hundreds of watts of continuous electrical power.

‘Solving these issues has required extensive and creative use of our unique Computational Fluid Dynamics (CFD) technology and will demonstrate that Wirth Research’s UAS technology has almost limitless application across multiple sectors.

‘This UAS system can be adapted to carry and power a variety of sensors including stereo high-resolution gimbaled optical cameras, high-resolution infra-red sensors, LIDAR imagers and ground penetrating radar sensors. The ability to carry and power such an extensive range of payloads makes this UAS technology ideal for a variety of industry sectors with multiple applications beyond its primary task of terrain mapping.

‘I’m also looking forward to developing further versions of this UAS concept for cargo transportation applications – for which it’s ideally suited – by virtue of its combination of VTOL capabilities, long endurance with zero emissions.

Wirth Research has also announced a partnership with HES Energy Systems.

HES founder and CEO Taras Wankewycz said, ‘The VTOL UAS developed by Wirth Research and powered by HES technology breaks new ground in the field of small but increasingly capable aerial robotics. There is no equivalent aircraft in the world able to demonstrate this level of flight endurance. We are shifting gears from a 200Wh/kg lithium battery capability to a 700Wh/kg fuel cell energy density capability, one that would radically change the applicability of drones, such as long-distance delivery, large area inspections at faster speed and lower cost, and a reduced need for expensive high altitude sensor payloads.’
