A recent research study commissioned by IMI reveals major grid concerns as airports move towards hydrogen-powered ground operations. The survey of 300 senior public transport professionals in the UK, Germany, and Italy indicates apprehensions regarding grid connections' ability to support the transition to hydrogen and battery electric fleets, emphasizing potential challenges for airport decarbonisation. Despite Europe's rapid expansion in hydrogen production, many decision-makers are cautious about large-scale hydrogen adoption. Most respondents see hydrogen as key to overcoming limitations of battery-powered fleets in airport operations. Challenges include the lack of permanent fuelling infrastructure and hurdles in hydrogen storage safety. The research highlights the importance of decentralised electrolysis to bridge gaps in infrastructure and facilitate the trial of hydrogen vehicles without dedicated filling stations. Notably, the study underscores the need for technical knowledge in deploying hydrogen-powered fleets. IMI's report, 'The Road Ahead,' explores decentralisation's role in facilitating hydrogen adoption, with a focus on on-site electrolyser technology's impact. It emphasizes the urgency for accelerating sustainable practices in airports to meet decarbonisation goals and calls for immediate progress. The findings point to the growing interest in hydrogen-fuelled vehicles and address the challenges faced, such as storage safety and infrastructure limitations. The report advocates for closer collaboration with developers to mitigate risks and promote the value of hydrogen-fuelled vehicles, especially in a sector lacking expertise in hydrogen technology. Overall, the study emphasizes the crucial role of hydrogen in achieving greener ground operations at airports and public transport systems, urging prompt action to address existing barriers and accelerate the adoption of sustainable practices.
