HES Energy Systems, the aerospace company founded in Singapore in 2009, is working to change the electric aerospace industry by optimizing smaller aircraft and drones powered by hydrogen and scaling up.
They have worked with other aerospace companies, universities, and government agencies worldwide to solve hydrogen logistic challenges.
One of the most important advantages of hydrogen is that it holds the most energy relative to its weight compared to any other element. However, it does require a significant amount of room, but is still more efficient than batteries when it comes to electric flight. Lightweight hydrogen is a possibility that is growing within the industry. These fuel cells would not burn hydrogen, only convert hydrogen to water and electricity without any moving parts. Hydrogen is also a zero-carbon fuel, and gives off no carbon dioxide emissions during flight. Lastly, refueling hydrogen is much safer and faster than extensive banks of lithium-iron batteries.
HES Energy Systems has officially launched the HYCOPTER, a hydrogen-electric multi-rotor drone capable of hovering for hours at a time. The first commercial version of HYCOPTER has been designed, tested, and is currently being assembled in Austin, Texas after many years of prototype development and testing. This cutting-edge drone is powered by lightweight, aerial, fuel-cell electric power systems, made by HES. Its special ultralight gas tanks can be refilled to 350 bar due to a special booster pump, which maximizes the storable energy in the form of hydrogen gas. Additionally, HYCOPTER allows integration with the most sophisticated sensors because of its 12V payload open bay, resulting in optimal flight time duration.
HYCOPTER features the possibility to customize flight durations by adjusting energy storage levels and payload weight, resulting in three main combinations:
- With 5L energy storage and a 2.5kg payload, flight duration will be 1.5 hours
- With 9L energy storage and a 1.5kg payload, flight duration will be 2.5 hours
- With 12L energy storage and a 0.5kg payload, flight duration will be 3.5 hours
Lithium-ion batteries can only support up to 20-30 minutes of flight time compared to the 3.5 hour maximum of HYCOPTER. Furthermore, HYCOPTER cylinders only take minutes to recharge using bottled industrial-grade hydrogen from local suppliers. HYCOPTER also incorporates HES’ new pressure regulator. This record pressure-reducing valve embeds key safety features such as a pressure burst disc and electric pressure transducer, and only weighs 140g. These innovations will help the HYCOPTER accomplish tasks that other drones simply do not have the capability for.
