Airbus’ “Hydrogen Hub at Airports” concept brings together key airport ecosystem players to better understand hydrogen infrastructure needs for future aircraft and to develop a stepped approach to decarbonising all airport-associated infrastructure using hydrogen.
The use of hydrogen to power future aircraft is not only expected to significantly reduce aircraft emissions in the air: it could also help decarbonise air transport activities on the ground.
And the need to do so is certainly there. In fact, airport-controlled activities account for around 2-3% of the aviation industry’s total emissions. This represents approximately 15–20 megatons of CO₂ emissions per year globally.
For this reason, airports are now beginning to rethink how their infrastructures could be designed and operated to reduce their overall environmental footprint. One promising option is to build a unique airport ecosystem with hydrogen at the core of operations.
In 2020, Airbus launched “Hydrogen Hub at Airports” to help airports reflect on how to do just that. The concept aims to jumpstart research into infrastructure requirements for future hydrogen aircraft, as well as low-carbon airport operations, across the entire value chain. And a variety of airport authorities, airlines and energy providers are already signing on to get involved.
Lionel Cousseins, ZEROe Market Development and Airline Relations Manager said “Airports have a key role to play to enable the transition to a climate-neutral air transport ecosystem. Hydrogen Hub at Airports enables us to collaborate with partners to define needs today, so we can pave the way for hydrogen adoption by 2035.”
Introducing the Hydrogen Hub at Airports concept
Airports are complex infrastructure assets that rely on deep interdependencies between multiple systems, structures and stakeholders. For example, ground transport at airports includes not only passenger transport to and from aircraft via buses, but also heavy-duty vehicles – such as aircraft tugs and cargo trucks – for logistics. Traditionally, these vehicles have been powered by fossil fuels, which contribute to airports’ overall emissions. But hydrogen could drastically cut the emissions of airport ground transport. In addition, airports require vast amounts of energy for cooling and heating, the environmental footprint of which could be mitigated through hydrogen.
The on-site production (and liquefaction) of hydrogen could also be a promising option for airports to meet their individual energy needs. This solution would eliminate the need for transport to and from off-site hydrogen production facilities, which would further reduce emissions. In doing so, airports could also become future energy ecosystems with liquid hydrogen production at their core.
