Design example for a highly mobile hydrogen refuelling station
Functionality of highly mobile hydrogen refuelling using the example of the MAX Mobile Refueler from Maximator: (1) The refuelling vehicle is refuelled at the public 700 bar truck filling station. (2) The already compressed hydrogen is brought to the machine by the transport vehicle. (3) Hydrogen is refuelled into the machine in a few minutes using a displacement principle with low energy input, whereby the highly mobile filling device is driven by the machine to be refuelled.

Icing on structures on the nacelle of a wind turbine
Webcam image of superstructures on the nacelle of a wind turbine with recognizable icing, which corresponds to the structure and consistency of clear ice directly on the structures and changes to hard rime as it progresses. The turbine is located at a test site of the Nergica center of applied research in eastern Canada. The webcam image is part of a dataset in the “Task 54 Icing Event Database”.

Modeled performance envelopes of rotor blade heating systems
Modeled performance envelopes as curves depending on wind speed and ambient temperature for different values of liquid water content (LWC) and surface temperature of the rotor blade. The curves were calculated with the “Task 54 Performance Envelope Model”.
