The article discusses the advancements in electric ground support equipment (GSE) in the aviation industry, focusing on the shift towards electric refuelling trucks for aircraft. Manufacturers like Skytanking, TITAN AERO, and Fluid Transfer International have developed fully electric refuellers with significant capacities, aiming to reduce emissions and improve operational efficiency. These electric vehicles offer benefits such as lower environmental impact, reduced noise pollution, and enhanced employee well-being. Moreover, innovations like high battery capacity, efficient charging systems, and unique safety features are highlighted as key drivers in the adoption of electric refuelling trucks. Additionally, the article explores the exploration of hydrogen as an alternative fuel for ground handling equipment at airports. Brussels Airport, in collaboration with VIL, DHL, and the Stargate EU Green Deal project partners, conducted a trial using a hydrogen-powered Mulag tractor and a temporary hydrogen refuelling station. The successful trial aimed to evaluate hydrogen's potential as a fuel option for ground handling equipment, alongside electric alternatives. Insights gained from the pilot program will be shared with other airports to promote sustainable practices in the aviation sector. While electric refuellers dominate the current landscape, the article emphasizes that hydrogen is also gaining momentum as a viable alternative, presenting a promising future for sustainable aviation practices.
