The lecture at the Diamond Building, University of Sheffield, will focus on the ambitious targets of the aviation sector to achieve net zero flight by 2050. Various pathways including legislative, operational, and technological advancements will be explored to contribute to this goal. A key aspect of the discussion will revolve around the development of technologies for future propulsion systems, with a particular emphasis on new and alternative fuels such as battery, hydrogen, and sustainable aviation fuels. James Hunt, the Future Propulsion Lead at AMRC with extensive experience in applied research, will be the speaker for the event. He will shed light on how different companies are approaching decarbonization, with a special mention of disruptive technologies and business models in the industry. The lecture will also touch upon the challenges faced in reducing aircraft emissions and how these challenges are being addressed. It will showcase the collaborative efforts of industrial partners in zero-emission transport technologies. James Hunt's involvement in projects like the ATI's FlyZero programme on hydrogen storage and collaboration with ATI’s Hydrogen Capability Network will provide valuable insights into the adoption of hydrogen in aviation. The event is open to RAeS members, branch friends, and students, with a nominal suggested donation for non-members to attend.
