SAF hubs: structuring the sustainable aviation fuel market at airports
SAF hubs link feedstocks, production and airports, making them the key to scaling up sustainable aviation fuel availability.
The SAF logistics challenge: from production to airport
Producing sustainable aviation fuel is not enough on its own: it still has to reach the tarmac, in reliable volumes and at a manageable cost. This logistics link is precisely what is holding back the wider adoption of SAF in Europe today.
Today's supply chain remains fragmented. Feedstocks such as used cooking oil, agricultural residues and green hydrogen for Power-to-Liquid pathways are geographically scattered, while production capacity remains limited and often located far from major airports.
This dispersion complicates transport and storage logistics, drives up costs and undermines airlines' visibility into the volumes actually available. Without a more integrated structure, SAF will remain confined to marginal quantities, far short of the targets set by European regulation.
SAF hubs: the missing link between supply and demand
A SAF hub is an integrated logistics platform, typically located close to a major international airport. It brings refining, storage and distribution of sustainable fuel together in one place, instead of spreading these functions across several distant sites.
A natural point of convergence
The hub connects three worlds that currently communicate poorly: feedstock suppliers, production units (adapted refineries, Power-to-Liquid sites) and final demand from airlines. By physically bringing these stages closer together, it smooths the entire chain.
Economies of scale and a lower carbon footprint
Grouping production and storage on a single site cuts overall logistics costs by pooling infrastructure. This proximity also limits long-distance road or rail transport of the fuel, reducing the carbon footprint associated with getting it to the aircraft.
Concrete impacts for market players
Structuring the market around hubs does not only benefit logistics operators: it changes market conditions for every stakeholder involved in SAF.
- Airlines: better visibility on available volumes, making it easier to sign long-term supply contracts (offtake agreements).
- Producers: identified, reliable hubs that reassure investors and make it easier to finance new capacity.
- Distributors: optimised flows across several production sites and airports, rather than one-off, costly deliveries.
- Regulators and airports: a concrete tool to track SAF ramp-up and anticipate progressive blending obligations.
Without structured hubs, SAF stays a scarce, costly product; with them, it becomes a supply that a fleet can actually plan around.
How Heeding supports this logistics transition
In an ecosystem that is still taking shape, finding a way through the available producers, distributors and hubs remains complex for a single buyer. Heeding was designed to simplify that navigation.
Heeding does not sell fuel itself: it is a marketplace giving access to offers from multiple producers and distributors operating on European SAF hubs. Buyers can identify the volumes actually available and injected into airport networks, rather than depending on a single supplier.
The platform lets buyers compare offers from different suppliers, reduce dependence on a single logistics operator and centralise orders. Every transaction comes with traceability and sustainability certificates (Proof of Sustainability), gathered in one place.
To go further, Heeding offers a Flash Diagnostic to analyse a fleet's needs and identify the most relevant SAF supply solutions.
