Oscar Maan, asset innovation manager at Royal Schiphol Group explains: “An aircraft needs power when it is stationary at the gate or on the apron to keep all systems on board running. Special diesel generators were used for this. In order to improve air quality and reduce emissions, we have been changing that for some time. For example, of the gates at Schiphol have a fixed power box for the aircraft. Our goal is to provide all gates with this.”
He continues: “Because there are not yet fixed power boxes everywhere at the airport and, for example, cargo planes are not at the gate, Schiphol has developed an electric and mobile generator together with ITW. We also call it an electric ground power unit (E-GPU).” Reduce emissions With the use of the E-GPU, the emission of CO2, (ultra) particulate matter and nitrogen disappears, compared to the diesel variant . 7 electric ground power units are currently in use at Schiphol. They are deployed on Pier D and are suitable for the smaller aircraft type, the narrow-body aircraft. Larger aircraft require more power than existing E-GPUs provide.
At Schiphol, three units with a double flow capacity will be tested in six months. The trial with three widebody E-GPUs will initially be carried out on cargo aircraft and then on passenger aircraft. Based on the experiences and collected data from the trial, conclusions can be drawn about deployability and roll-out at Schiphol.
Royal Schiphol Group wants to operate the most sustainable airports and has the ambition to have an emission-free ground operation in at its Dutch airports. You can read more about it here: Schiphol | Towards sustainable aviation.128
