We are developing a hydrogen powered eVTOL drone capable of flying over 300 km without refueling. This way, we want to build the world's longest range eVTOL drone below 25 kg Take-Off Mass. We achieve this by using state-of-the-art fuel cell systems and modern Type IV pressure tanks. This way, our Prototype "Mercurius" will outperform any other commercial drone. Our Idea was part of the top three winning teams of the NASA-DLR Designchallenge 2020 and part of the top ten pitching ideas of the TUM IdeAward 2020.
Using Hydrogen to revolutionize UAVs
LEVITUM is a team of more than 40 highly motivated Master and Bachelor students of the departments of Mechanical Engineering, Aerospace, the TUM School of Management, Electrical Engineering, Physics, Information Technology and the Munich School of Engineering.

With an energy density of 33.33 kWh/kg hydrogen has more energy density than any other element. The hydrogen fuel cell offers a possibility to use this potential efficiently for electric powertrains. Modern hydrogen tanks already achieve usable electrical energy densities of over 1600 Wh/kg. This is more than six times the capacity of modern lithium ion batteries.
High Safety Level
Hydrogen fuel cell systems are safe. Modern Type IV pressure tanks are safe against overpressure, fire or even bullet impact. In case of emergency, the hydrogen can be released through a PRD within a very short time. Due to the 13 times lower density of hydrogen compared to air, it evaporates immediately without any danger to the environment.
According to the US Department of Energy (DoE), fuel cells can be produced cheaper than a comparable lithium-ion battery system, depending on the powertrain. The cost advantage is reinforced by the longer service life of more than 3000 operating hours and optimal utilization due to refueling times of less than 5 minutes. There are already first manufacturers developing fuel cell systems for drones.
Bringing Fuel Cell propulsion to UAVs
The Mercurius project takes drone technology to the next level. The concept, which has been awarded as one of the best three designs of the NASA - DLR Designchallenge 2020, uses modern fuel cell technology to give drones higher ranges, minimum refueling times and lower costs.
We now bring this dream to reality and build a prototype!
