A new company has formed to advance cryogenic electrical machine technologies for zero-emission aircraft. HPDrive Technologies, launched by the University of Nottingham and GKN Aerospace, will develop lightweight, high-efficiency systems capable of operating at megawatt power levels.
The venture focuses on hydrogen-electric aviation and other high-power sectors, starting with aerospace applications. Its leadership stated the company combines expertise in cryogenic systems, advanced coil technologies, and electrical machine design, all essential for future propulsion systems.
Accelerating technology development
HPDrive will build on technologies developed through the H2GEAR programme. It is already progressing on its technology roadmap and engaging with potential partners in aerospace and other industries.
Max Brown, Vice President of Technology at GKN Aerospace, described the venture as a strategic move to build a nationally important capability. “Through this collaboration with the University of Nottingham, we support the continued development of technologies needed for the long-term transition toward zero-emission flight,” he said.
The university framed the launch as part of its broader effort in zero-carbon technologies and sustainable transport. This work aligns with its Hybrid Propulsion Systems facility, which received co-funding from the UK Research Partnership Investment Fund.

Professor Henner Wapenhans, CEO of HPDrive, said the company was built on complementary expertise. “Through this new venture, we will further develop advanced cryogenic electrical machine technologies and speed their path toward industrial and aerospace applications,” he said.
A step toward hydrogen-powered flight
Cryogenic electrical machines are considered essential for hydrogen-electric aviation, where extreme cold improves efficiency and reduces weight. The technology may also apply to other high-power uses, though aerospace remains the main focus.
George Rice, Director of Knowledge Exchange and Business Engagement at the university, called the collaboration a rewarding process to establish a nationally significant technology platform. “The University and GKN Aerospace will continue supporting the company as it moves toward commercialisation,” he said.
HPDrive’s first priority is refining its core technologies and securing partnerships to scale production. Success could help shape the future of flight, where hydrogen replaces jet fuel as the primary power source.
Its work may determine whether zero-emission aircraft become a reality.
