Development of a gas turbine generator with a 20 mm rotor

This paper reviews the status of the Belgian PowerMEMS project [1]. Focus is on the technology developments for realizing a 20 mm diameter hydrogen-based gas turbine. The total device consists of a compressor, turbine, combustion chamber, generator and recuperator. It has a total diameter of 100 mm and is 112 mm long, and has an expected electrical power output in the order of 1 kW.
