Developing requirements for future electrical machine manufacture to achieve a net zero future

This paper summarises work done by the EPSRC Future Electrical Machines Manufacturing (FEMM) Hub on its technology roadmap. It outlines the challenge, approach and progress to-date in linking the role of electrical machines in the journey to net zero with specific research challenges. It has been based on a net zero CO2 emissions future as the end point, and explores what developments in electrical machines manufacture will be needed to get there. Given the likely role of electrical machines in a net zero future it seems natural that a roadmap in this area seeks to understand and describe what this means in terms of electrical machines and how they need to be made in future. This work sits alongside other roadmaps, focused on the journey to net zero in various industry sectors. It provides unique additional insight by focusing specifically on machines and by considering needs and implications across sectors from power generation to surface and air transportation. As a research hub, FEMM Hub's primary intent has been to use this approach as a basis for identifying the early TRL research needs. Inevitably however the problem has many facets and several findings extend into likely public policy and industrial transformation.
