Challenges and Opportunities in Next-Gen Cryogenically Cooled Electric Propulsion Systems

Registration opening soon

Electrification, whether full or hybrid, is essential for zero-carbon future transportation. However, current electric propulsion systems are too heavy and inefficient. Conventional cooling with air, water, and oil is limited by heat transfer properties. For hydrogen-powered aircraft, combining electric and cryogenic fuel systems offers potential. Liquid hydrogen (~20K) can reduce resistive losses and improve efficiency, but challenges remain in material behaviour, thermodynamics, and system design.

This seminar will explore cryogenic coolant applications in electric propulsion systems, focusing on conventional windings (copper or aluminium, non-superconducting). Topics will include the liquid hydrogen supply chain, the cryogenic behaviour of electric propulsion components and the design of cryogenically cooled electrical propulsion system. The latest developments in cryogenically cooled electrical machines such as cryogenic pumps will also be discussed.

Liquid Hydrogen Taking Flight – The key research challenges to enabling Liquid hydrogen commercial aircraft.
by Huw Edwards of Aerospace Technology Institute

An overview of the key research challenges to enabling liquid hydrogen commercial aircraft and the activities within the Hydrogen Capability Network to address these.

Metrology for magnetic materials at operational conditions
by Daniel Brunt of NPL

The push towards electrification and greener technologies will see an unprecedented uptake in electric machines and subsequently magnetic materials. To achieve the greatest efficiencies, it’s imperative to have accurate data at conditions representative of those under operation. In this presentation I give an overview of the work we’re doing to take measurements from standard lab-based measurements and perform them at operational conditions, including measurements down to cryogenic temperatures.
