Scientists may soon discover a breakthrough that could change flight as we know it. The University of Nottingham has launched a £5.3 million ($6.76 million) research program that could result in major changes in aerospace engineering.
The new program aims to develop a cutting-edge cryogenic hydrogen-electric propulsion system. This new research program is part of a broader GKN Aerospace-led £44 million H2FlyGHT project.
What is Net-Zero Air Travel?
Flying is far from environmentally friendly. Those that are environmentally conscious desire to change this.
Net-zero air travel means that there is no combustion of fossil jet fuel. Net-zero travel by plane would be achieved when no incremental greenhouse gasses would be added to the atmosphere when flying. As of right now, this is not possible. However, new research could change this.
An Amazing Prototype Engine
The H2FlyGHT project’s initiative aims to create a 2-megawatt (MW) prototype engine that will transform the aviation industry. This new engine will pave the way for larger, more sustainable aircraft in the future.
This H2FlyGHT collaboration with the University of Nottingham aims to integrate fuel cell power generation, cryogenic power distribution, and advanced cryogenic drive systems. The goal is to create a cohesive propulsion unit that combines these technologies.
Unveiling the Initiative
The collaborative initiative was officially unveiled at the Farnborough International Airshow in England in July of 2024. It captured the attention of both industry leaders and policymakers.
Many scientists are curious about the research that those at the University of Nottingham are completing. Those concerned about the environment are hopeful about the new research. Even England’s government is investing in the possibilities that this new research could unveil.
Pushing Limits
The University of Nottingham and H2FlyGHT project collaboration is supported by the United Kingdom Government through the Aerospace Technology Institute (ATI) program. The ATI also includes partners such as Parker Meggitt and the University of Manchester.
“The vision of net-zero air travel is within our sights,” said Chris Gerada, a Professor of Electrical Machines and the lead for strategic research and innovation initiatives at the University of Nottingham. “However, to get there, we must push the limits of what is technically possible.”
A Hub for Hydrogen Propulsion Research
A paramount part of this riveting research is the University of Nottingham’s new state-of-the-art hydrogen propulsion systems facility. This facility is home to several specialized laboratories. Each of these special laboratories will play a crucial role in developing the new cryogenic hydrogen-electric propulsion system.
Scientists using the facility’s cryogenics lab will concentrate on developing low-temperature environments to enhance the efficiency of electrical systems. Researchers will be able to test megawatt-scale fuel cells alongside battery and motor systems in simulated altitude conditions.
The Hydrogen Propulsion Systems Facility
The new hydrogen propulsion systems facility builds upon the University of Nottingham’s existing strengths in electrification research. In particular, the university’s Power Electronics and Machines Centre (PEMC) is extremely well regarded; it features one of the largest research teams in the world in the field.
In addition to the physical labs, there will be a complementary digital twinning lab where engineers can use advanced simulations to optimize designs and enhance operational performance.
Exploring Cryogenic Technology
Cryogenic technology is another absolutely crucial component of the university’s research program.
A lack of viable storage has been a significant barrier to making hydrogen-powered clean flight a reality. When cooled to extremely low temperatures, hydrogen can be stored as a liquid. This liquid hydrogen has a much higher energy density. The University of Nottingham research team believes that they will solve this need for compact, high-energy fuel storage.
Motor Design and Cryogenic Inverter Technology
The University of Nottingham’s Power Electronics, Machines, and Control (PEMC) research group will lead the development of both the full motor design and cryogenic inverter technology.
These advancements are crucial for creating high-power, efficient propulsion systems. They will help to power the next generation of environmentally-friendly aircraft.
A Greener Tomorrow
Professor Gerada highlighted, “Thanks to our new propulsion research infrastructure on campus, industry can co-locate, research, prototype, automate, and manufacture the new solutions they need to future-proof their business.”
As the University of Nottingham advances its groundbreaking research in cryogenic hydrogen-electric propulsion, the vision of net-zero air travel moves closer to reality. With significant investments and a robust collaborative effort, this initiative promises to redefine aerospace engineering and set new standards for sustainable flying. The innovative work being done today could lead to a cleaner, greener, and more efficient future for air travel.
