HY4 as emission free Future

After the flight around the world by Solar Impulse 2, the HY4 claims to be the next step of emission free passenger flights. „The realization of small emission free passanger flights is close.“ Prof. Dr. Josef Kallo

HY4 at Hannover Messe 2016

The HY4 – a four-seater passenger aircraft prototype – is due to take off for its maiden flight in the summer of 2016, using an electric propulsion system that draws most of its energy from a hydrogen fuel cell. The partners of research and development, such as DLR Institute of Engineering Thermodynamics, Hydrogenics, Pipistrel, H2FLY, the University[…]

We proudly present – HY4

„With the HY4, we want to bring electromobility to the air, demonstrating the feasibility of this technology and identifying specific fields of application in passenger transport,“ explained project leader Josef Kallo, during the official presentation of the project at the International Trade Fair World of Energy Solutions on 12 October 2015 in Stuttgart. more…
