Josef Kallo is co-founder and Chief Technology Officer (CTO) of H2FLY - a company that specializes in the development of hydrogen-electric powertrain systems for aircraft headquartered in Stuttgart, Germany. As an entrepreneur, he financed the first round of H2FLY aiming early for a transfer of technology from basic knowledge to a first flying prototype.

Under Kallo’s leadership, H2FLY has achieved significant milestones, including the world’s first liquid hydrogen flight of the HY4 aircraft and the successful development of a high-performance fuel cell system for Joby’s hydrogen-electric eVTOL aircraft demonstrating the potential of hydrogen-electric powertrain systems for various commercial aircraft applications.

Josef Kallo has an extensive background in power electronics and energy technologies with international research collaboration with partners in Japan (JAXA), France (CEA, Onera), and Spain (INTA). From 1999 to 2006, he was a Project Engineer at General Motors Global Alternative Propulsion Center focusing on the application of hybrid powertrains. After that, he coordinated numerous development projects at the German Aerospace Center (DLR) focusing on battery, fuel cell and hybrid-electric powertrains.

Since 2015, he has led research in energy management for hybrid powertrains as a Full Professor at the University of Ulm and additionally assumed the position of Primary Investigator at the Helmholtz Institute for Electrochemical Energy Storage. He is a passionate pilot.

Peter has a proven track record of achievement in both academic and industrial research and development of novel electrical power systems. Peter has extensive experience of directing and guiding university and industrial research and successful product development resulting in new patents and new products. Peter has made a significant contribution to R&D of new technologies including high temperature superconductors, wide-band-gap semiconductors and novel network designs. Currently researching technologies associated with Hybrid and Electric aircraft propulsion systems.

Peter is currently working in the School of Engineering with an objective to build on the work done in the field of More Electric Aircraft and create research activities in the field of Hybrid Electric Aircraft.

I have 24 years of experience in aerospace at Pratt & Whitney Canada, Bombardier Aerospace and Bell Helicopter, encompassing different roles in design, integration, test and aftermarket on programs like the A220 (former C-Series), Global 7500, Boeing 787, CRJ, Bell 429 and various engine models.

I have been involved at different stages of the product lifecycle, from product development, entry into service up to mature product support.

In my current role, we install a new hybrid-electric propulsion system in a legacy airplane.

This work will allow us to capture essential information for future product definition of hybrid electric propulsion, including complex integration challenges.
