Brussels Airport, in collaboration with VIL, DHL, and other partners, is currently conducting a pilot project to test the feasibility of hydrogen-powered vehicles for ground handling operations. This initiative, part of the Stargate project, aims to assess the potential of hydrogen as an alternative fuel source in aviation. The project involves the installation of a mobile hydrogen refuelling station on the airport's tarmac and the testing of a hydrogen-powered Mulag towing tractor by DHL. The goal is to evaluate the performance of hydrogen fuel in comparison to electric ground handling equipment, focusing on reducing emissions and noise impact during ground operations. Training programs are also in place to ensure safe and efficient handling of hydrogen fuel by operators and personnel. The six-week test period will provide valuable insights into the practicality and benefits of hydrogen technology in aviation, with implications for permit applications, safety procedures, and operational experiences at airports. The use of hydrogen offers advantages such as instant refuelling, zero CO2 emissions, and noise reduction, contributing to a more sustainable aviation industry. This project sets a significant milestone in the adoption of hydrogen technology in airport operations, demonstrating the potential for a greener and more efficient future in aviation.
