Aidan White

Engineer in the Clean Fuels Team

Aidan is an engineer in the Clean Fuels team at TÜV SÜD National Engineering Laboratory where he focusses on the flow measurement challenges for clean fuels (specifically hydrogen). His latest work includes the design of a new gas flow primary standard facility that will allow calibration of sonic nozzles in hydrogen at pressures up to 120 bar and flow rates up to 100 Sm3/h.
