Stakeholders in the aviation industry are gearing up for the future with plans to introduce hydrogen refueling systems at airports ahead of the commercial service expected to begin by 2035. The focus on sustainability and low-emissions aircraft was emphasized at the recent International Air Transport Association (IATA) World Sustainability Symposium in Miami. During the symposium, discussions revolved around the collaborative efforts required to upgrade on-airport fueling infrastructure to support the upcoming generation of hydrogen-fueled aircraft. Although the deployment of aircraft utilizing hydrogen fuel is still a few years away, countries like Australia, the US, France, and Canada are proactively preparing for this transition. The move towards hydrogen as a fuel source marks a significant step towards reducing carbon emissions in the aviation sector. The industry's positive outlook and proactive approach in developing hydrogen refueling systems indicate a promising future for sustainable air travel.
