KES and KLM recently conducted the first live test of Dynell’s DHM 090 model hydrogen GPU on an Embraer aircraft at Amsterdam Airport Schiphol. The test was part of a consortium project for the European Union’s TULIPS program, involving partners like Schiphol Airport, Zepp Solutions, KES, and KLM. The successful test aimed to showcase the viability of hydrogen-fueled GPUs as an alternative to diesel- and battery-powered units in the ground support market. The DHM 090, providing 350kWh for 90kVA operation, was praised for its performance in supplying ground power to the aircraft without significant disruptions to airport operations. Dynell and partners plan to continue testing the unit's endurance and performance in different climates at airports in Italy and Cyprus. The hydrogen GPU's advantages include quick refueling, scalability for larger aircraft, and superior energy capacity compared to battery GPUs. The testing phase will provide insights for further improvements in tank size and battery optimization to enhance the unit's efficiency and effectiveness in aviation operations.
