05-06.10.2017, Stuttgart Symposium E2Flight
One of the biggest symposia on electric flying took place in Stuttgart under the main topics “Technological and Political Progress in Electric Flight”, “Hybrid Systems and Energy Storage”, “Energy Conversion, Safety and Certification Aspects” and “Integration Aspects and Flying Hardware” , Organized and carried out by the German Aerospace Center together with the University of Ulm, the latest findings on electrification of aviation were exchanged in lectures and discussions with renowned representatives from industry and research. Lectures by Frauke Pleins-Schmidt from the German Federal Ministry of Transport and Digital Infrastructure, Starr Ginn from the NASA Armstron Flight Research Center and Prof. Josef Kallo from the University of Ulm show only a fraction of the high-caliber lectures and participants. In addition, the forum was used to make contacts and share know-how. This Syposium once again showed the positive trend of technology development and gives hope that electric aircraft will be soon mass produced and operated.
21.07.2017, Ulm – Silent and quiet, the Hy4 inspires about 7000 visitors during the Long Night of Science at the University of Ulm.
The H2Fly GmbH shows with the Hy4 as part of the Long Night of Science at the University of Ulm how the future of aviation will look like. Quiet as the night, the Hy4 flies with its emission-free hydrogen fuel cell – battery hybrid system. The approximately 7,000 visitors had the opportunity to learn about the new drive technology and its possibilities and to discuss the development of the market for emission-free aircraft and the value of this new development with the engineers. In the aviation industry H2Fly GmbH is already known as a trend-setting company with an intensive focus on the development of emission-free aviation. As part of the Long Night of Science, all interested parties were also able to find out how the company fullfill the work around the aircraft and supports the Institute for Energy Conversion and Storage from the University of Ulm as a partner in the development of power electronics for the Hy4. The exhibition was supported by the scientists of the institute, who were able to explain their work in detail. They explained that work is currently being done on the further development of power electronics.
After the response to the symposium had been tremendous, the organizers decided to host the symposium at Stuttgart Airport again this year, after 2015 and 2016. The focus is on the development of overall concepts for electric flight, system development and approval
24-25.06.2017, Frankfurt – H2Fly GmbH wins on the day of the aviation (24.06.-25.06.2017) at the Frankfurt airport many new interested parties for emission-free passenger flights.
The H2Fly GmbH puts an end to the long wait of all aerospace, environmental and technical enthusiasts and presents the Hy4 for the first time after the successful first flight on September 29, 2016 in Stuttgart as part of the “Day of Aviation 2017” at the Frankfurt Airport.
H2Fly GmbH has been known for many years as a reliable supplier for the qualification of emission-free drive trains for aviation. When the Hy4 was recently confirmed for Aviation Day at Frankfurt Airport, the response from customers and business partners was very positive. Profitable technology and a winning concept are just two of the buzzwords frequently cited by visitors in connection with the first four-seat and zero-emission passenger hybrid aircraft powered by fuel cells and batteries. Independent industry experts praised the special combination of proven aircraft technology and innovative drive technology. The all-electric aircraft Hy4, as presented at Frankfurt Airport, was a high-profile innovation and has the potential to challenge the competitive advantages of established providers. The management, the development partners and leading experts agree on the high acceptance of the new development. The special feature of the Hy4 is the combination of unconventional propulsion technology and a new safety environment for aviation, which is also recognized by operators users and users.
The organizers created a great aviation event over a weekend in perfect weather with over 30 exhibits and offered many highlights from the past, present and future as well as a fascinating program around the topic of flying. Presenting the Hy4 to more than 80,000 people was a win-win for everyone involved and reflects the strong public’s interest in the further development of climate-friendly and emission-free transport technologies.
22.06.2017, Stuttgart – An extraordinary vehicle meets an extraordinary aircraft
As part of the hydrogen Germany tour organized by Toyota Motor Europe NV / SA, the Mirai team visited the Institute of Technical Thermodynamics at the German Aerospace Center. At the Stuttgart location, the enthusiasm of the approximately 40 traveling journalists was clearly felt when they presented the capabilities of the new drive technology, not only on the ground, but also in new aviation applications.
Emission-free drives are already familiar to anyone in terrestrial short-distance traffic. But in order to increase the acceptance of the population, other technologies must be developed to bridge even the longer distances. This gap is closed by hydrogen in combination with fuel cell technology. With the vehicle Mirai, Toyota presents an application that is already produced in small series. With a range of 500km and a refueling time of 3 minutes, the concept shows that even high ranges can be covered without emissions. However, hydrogen fuel cell technology is also suitable for aerospace applications. The Hy4 of the H2Fly GmbH shows that it is possible to transport 4 passengers in the aircraft quiet, traffic and emission-free over longer distances. “With hydrogen / fuel cell technology, we now have the opportunity to become independent of fossil fuels and to operate the short-haul routes with emission-free aircraft up to approx. 1000km. Hydrogen is the fuel of the future and is available indefinitely. It`s the key ftechnologie for emission-free passenger flights, “Thomas Stephan, Managing Director of H2fly GmbH, explains the future potential of the Hy4. Prof. Josef Kallo, Head of the Institute for Energy Conversion and Storage at the University of Ulm and Coordinator for Electric Aircraft Activities at the German Aerospace Center also dares to look into the future. “Even internationally, the hybrid technology of hydrogen fuel cells and batteries will continue to prevail. Conceivable are planes with up to 40 passengers and a range of 2000km at 500km / h. Here we are setting main points with the operation of the technology in the aircraft. I am convinced that hydrogen technology will secure future competitive advantages for Germany as a location and strengthen our position in the international market. “All parties involved are obviously fully aware of the pioneering features of the Aware of hydrogen technology and hope that with this successful meeting of two pioneering applications, it has been shown that it is possible to meet the requirements of future passenger transport in a sustainable, quiet and emission-free manner.
Saturday / Sunday, 24 / 25.06.2017, 10am to 6pm, CargoCity South, Frankfurt
The Hy4 will be the first emission-free passenger aircraft to fly at Frankfurt Airport on the day of aviation. On the 24th and 25th of June 2017, from 10 am to 6 pm the team Hy4 will answer questions about alternative propulsion systems, e-mobility and fuel cell airplanes at the future terminal 3 directly at the object.

We look forward to all aviation, environmental and technical ethusiast
With the “European Fuel Cell Tour” Toyota and the trade journal “Firmenauto” show that it is already possible to drive CO2 neutral over long distances. Because the advantage of fuel cell technology is evident in the long distances, which, unlike with a pure battery drive, can be achieved by the high energy density of hydrogen. The tour starts on
During the Tour, the Toyota team will refuel exclusively with CO2-neutral hydrogen produced and head for a number of key players from the research and industry sectors on the topic of hydrogen and fuel cells along the way.
The DLR energy research at the Stuttgart location focuses on the research of environmentally friendly, efficient and affordable energy supply and storage and may not be missing as a station at the Mirai Tour.
As an important partner for the integration of hydrogen technology in aircraft, this will be done at the DLR location Stuttgart at the Institute for Technical Thermodynamics on 14.07. and 21.07. 2017 an internal press event. The specialist audience will be informed about the activities related to hydrogen research and with the Hy4 a accessible application for solving the mobility problems of tomorrow. Because not only on the road you can move emission-free. Even in the air, a pollution-free movement is already possible today.
