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.

14.07.-21.07.2017, Toyota Mirai visits the Hy4

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.

29.09.2016, Maiden flight of emission-free four-seat passenger aircraft HY4

  • 29.09.2016 - Erstflug Hy4

On September 29, 2016, the four-seat passenger aircraft HY4 took off for the official first flight from Stuttgart Airport. The HY4 is the world’s first four-seat passenger aircraft powered solely by a hydrogen fuel cell battery system. Scientists of the German Aerospace Center (DLR) developed the powertrain of the aircraft and worked together with partners from industry and research in the project.

The HY4 fuel cell aircraft was developed by the DLR Institute for Technical Thermodynamics ( DLR-Institut für Technische Thermodynamik) with its partners Hydrogenics, Pipistrel, H2FLY, the University of Ulm (Universität Ulm) and Stuttgart Airport (Flughafen Stuttgart). DLR scientists were responsible for the development of the hydrogen fuel cell drive and its integration into the aircraft. The powertrain consists of a hydrogen storage, a low-temperature hydrogen fuel cell and a high-performance battery. The fuel cell converts the energy of the hydrogen fuel directly into electrical energy. The only waste product is water. With the electricity thus obtained, the electric motor drives the propeller of the aircraft. The on-board lithium-ion battery provides extra power during take-off and ascent flights. If the hydrogen required for the fuel cell is generated by electrolysis, which uses electricity from renewable energies, the HY4 will fly completely emission-free, not only local. The aircraft is operated by the DLR spin-off H2FLY.

Important step for sustainable aviation

Violeta Bulc, European Commissioner for Transport, said on zero-emission flying:”I am proud thats hy4_slowenien European researchers and manufacturers have realized this hydrogen fuel cell-powered aircraft, which is a forward-looking activity that embodies the future of zero-emission flying We strongly support initiatives that are fully in line with our new low-emission mobility strategy, which has an important role in bringing people together, connecting large cities and remote locations, and ensuring that businesses grow and develop The EU will continue to support such initiatives to drive innovation. ” Prof. Georg Fundel, Managing Director of Flughafen Stuttgart GmbH, is pleased that the first flight took place at Stuttgart Airport: “Both Stuttgart Airport and aviation in general expect further growth in the future, which is an important reason for us to have an environmentally friendly and perhaps one day even set emission-free flying and innovative technologies. “

Electric Air Taxis in regional transport
“Large passenger aircraft will still be able to fly with conventional power trains for the foreseeable future, but it will be one of the great challenges of the next decades to blow up electromobility and make the air traffic of the future CO2-neutral,” says Prof. André Thess, Leiter of the DLR Institute of Technical Thermodynamics. “Our goal is to further improve the fuel cell powertrain and bring it to life in regional aircraft with up to 19 passengers.”

hy4_stuttgart2The electric motor of the HY4 has an output of 80 kilowatts and allows a top speed of around 200 and a cruising speed of 165 kilometers per hour. Depending on speed, altitude and payload a range between 750 and 1,500 kilometers is possible. Striking feature of the HY4 are their two hulls, which are very firmly connected to each other via the wing. In each of the two hulls two passengers have space. The maximum weight of the HY4 is 1,500 kilograms. “With the HY4, we now have an optimal platform to further develop the use of the fuel cell in aircraft,” says Prof. Josef Kallo, head of the HY4 project at the DLR and professor at the University of Ulm. “Small passenger aircraft such as the HY4 can very soon be used in regional transport as electric air taxis and offer a flexible and fast alternative to existing means of transport.”
