Professor Julian Dunne gave a plenary lecture in Rome on 10th March 2025 at the Global Annual Meet on Mechanical and Aerospace Engineering (GAMMAE2025) entitled:  ‘Resonating free piston generators and their optimal control running on hydrogen’.

This lecture initially reviewed free-piston generator developments, highlighting the published benefits, especially in terms of gravimetric and volumetric power densities compared to existing energy converters before going on to discuss efficiency benefits and associated control problems. The particular reasons were then explained why hydrogen is a suitable free piston generator fuel.  The focus then switched to resonating free piston generators, especially the benefits of the rotary version, where emphasis was placed in the lecture on their design and optimal control.
