Keith Robert Pullen

Professor Keith Robert Pullen is a distinguished academic and inventor in energy systems engineering at City St George’s, University of London, where he has served since 2008. His career spans both academia and industry, with a focus on flywheel energy storage, high-speed electrical machines, and low-carbon power generation. He co-founded multiple spin-out companies, including Hydroventuri Ltd and Gyrotricity, and holds numerous patents in axial flux generators and turbo-compressors. His research integrates engineering innovation with practical applications for rural transport and developing countries.

• Education: PhD & DIC in Mechanical Engineering (1991), BEng in Mechanical Engineering (1987) from Imperial College London, sponsored by Rolls-Royce.

Research Interests center on electrically driven flywheel systems, turbo compressors for fuel cells, and energy technologies for rural Africa. His work bridges mechanical engineering, renewable energy, and automotive innovation, with applications in hybrid vehicles and rail transport. Recent projects explore acoustic microdevices for biomedical engineering.

Publications emphasize kinetic energy storage, microturbines, and phase-change materials. His grants include EPSRC-funded SCORE (Thermoacoustic engine), BIPED (EV batteries), and VESI (EV integration), alongside InnovateUK projects like LCEF (automotive flywheels with Nissan) and FCAMS (fuel cell compressors).

• Awards: Enterprise Fellowship (Royal Academy of Engineering), Fellow of the Institution of Mechanical Engineers, and Esso Teaching Fellow.
• Leadership: Director of Ascending Power Ltd and Dynamic Boosting Systems Ltd, and co-founder of Hydroventuri Ltd and Gyrotricity.
