Why scaling SAF means rethinking the Aviation Fuel system
Sustainable Aviation Fuel (SAF) is no longer a future ambition. It is now a live operational requirement.
As mandates take effect across the UK and Europe, the challenge is shifting from supply targets to delivery reality. The question is no longer whether SAF will scale, but whether the infrastructure around it can keep pace without disrupting operations.
This comes at a time when the aviation industry is already operating under pressure. Tight turnaround schedules, constrained airport capacity and ongoing disruption across parts of the network mean there is little room for error. Recent geopolitical instability and disruption to global fuel supply routes have further exposed how fragile parts of the aviation energy system remain.
At Oxalis Logistics, we believe the industry’s biggest challenge is not whether SAF can work technically. It is whether the supply chain can scale quickly enough to successfully support rising demand.
Under the UK SAF Mandate, SAF must make up 2% of total UK jet fuel demand from 2025, rising to 10% by 2030 and 22% by 2040. The result is a rapid shift in our client conversations. What was once ESG-led conversation is becoming a compliance requirement with real operational consequences.
Integrating SAF into this environment is not simply a sustainability milestone. It is an operational challenge that will define how successfully the industry transitions in the years ahead.
SAF demand is rising faster than infrastructure
The pace of SAF adoption is increasing, but supply and logistics infrastructure remain constrained.
Currently, Phillips 66 at Immingham is the UK’s only large-scale SAF producer, meaning most SAF used in the UK is still imported. That creates pressure across terminals and transport operations.
The industry is also facing wider challenges:
- Limited UK blending infrastructure
- Restricted tank availability
- Rising fuel costs
- Supply reliability concerns
- Increasing documentation and chain-of-custody requirements
- Fragmented sustainability reporting processes
- Dedicated or cleaned tankers not required for regular Jet fuel
These constraints are now being felt in real-time through pricing volatility, supply uncertainty and increased operational complexity.
For operators involved in SAF logistics this creates a highly complex operating environment where flexibility and safety become critical.
What makes aviation fuel logistics different?
Aviation fuel logistics operates in a zero-defect environment.
Unlike standard road fuel distribution, aviation operations leave no margin for fuel contamination, missed delivery windows or procedural failure. A delayed or failed delivery can disrupt or delay airport operations and trigger significant commercial and regulatory consequences.
The expectation is simple. Fuel must be available exactly when required, in the correct specification and with full traceability.
This environment is shaped by strict quality assurance procedures, tightly controlled access to airport sites and highly coordinated delivery windows aligned to flight schedules. Airside operations introduce additional layers of complexity, from security clearance requirements to limited access points.
Every movement also sits within a fully traceable system. Increasingly, this means maintaining clear visibility of fuel origin, handling processes, sustainability documentation and blending certification at every stage of the journey.
As SAF volumes grow, this administrative burden will increase alongside the physical fuel movements themselves.
But why does SAF add more complexity?
At aircraft level, SAF is designed to be a drop-in fuel when blended. The complexity sits around how that fuel is handled before it reaches the wing.
Although blended SAF behaves similarly to conventional Jet A-1 fuel once it enters a terminal or airport fuel farm, the operational environment around it is far more controlled.
And when neat SAF is handled, additional tanker cleaning and segregation procedures may be required. Documentation requirements also increase significantly, particularly around Proof of Sustainability and batch traceability.
Infrastructure constraints also begin to surface more clearly. Pressure points often sit at blending-capable terminals, tank allocation within fuel farms and the compatibility of shared pipeline systems. Delivery scheduling becomes more sensitive as these constraints interact, particularly during periods of high demand or limited supply.
In practice, this means SAF logistics is becoming just as much a documentation and coordination challenge, as it is a transport challenge.

The priority during the SAF transition is clear. Fuel supply must remain consistent.
Introducing SAF cannot come at the expense of operational reliability. This requires a logistics model that can respond to changing demand patterns and maintain resilience in a constrained system.
That includes the ability to:
- Maintain trained driver availability across key locations
- Load from multiple terminals where required
- Respond to surge-demand during peak operational periods
- Adapt quickly to supply disruption or terminal constraints
- Maintain business continuity during operational disruption
Oxalis Logistics has never recorded a service failure on an aviation contract. That track record reflects a safety-led operating model where reliability is designed into every movement, not managed retrospectively.
In practice, this is underpinned by 24/7/365 operational control through our Huddersfield Control Centre, providing continuous oversight of vehicle movements and airside access. This enables immediate intervention when conditions change, including weather disruption, congestion or terminal delays, with active re-planning in real-time rather than post-incident recovery.
In the event of a SHEQ incident, Oxalis Logistics operates with robust, fully tested response mechanisms designed to take control of the situation and manage risk. Emergency response capability is embedded into our daily operations, ensuring incidents are handled quickly and efficiently – protecting people, aircrafts and airlines.
Our ability to deliver this consistently is rooted in the scale and structure of our operations. Learn more about our UK and Ireland logistics network.
What does SAF-ready logistics actually look like?
True SAF readiness is not about completing a single demonstration project. It is about consistently and safely integrating SAF into aviation operations at scale, without increasing operational or compliance risk.
At this stage of the transition to SAF, the challenge is no longer volume, it’s complexity.
That includes managing constrained infrastructure, coordinating across multiple interfaces and maintaining compliance in a system where documentation and traceability are becoming as critical as the fuel itself.
This is where a practical logistics partner becomes essential. Oxalis Logistics operates as an early-phase SAF operator, focused on managing that complexity safely and consistently. This includes:
- Dedicated and controlled tanker management for SAF movements
- Proven ability to operate around terminal constraints and blending models
- Deep interface experience across refineries, terminals and airport fuel farms
- Strong documentation discipline and chain-of-custody compliance
In practical terms, this is supported by 24/7 operational control, aviation-grade safety processes and the ability to manage both physical fuel movements and the documentation that supports them.
As SAF pressure grows, the aviation industry will increasingly rely on logistics partners with proven transferable capabilities across future fuels.
SAF doesn’t fail at the aircraft. It fails in the supply chain. But avoiding this requires capability across five key dimensions and a confidence that new fuels and new demands are handled by an operator already trusted in aviation.
In aviation environments, safety is not a compliance exercise. It is fundamental to operations.
At Oxalis Logistics, safety is explicitly defined as the number one priority and embedded into how operations are designed and delivered. This includes:
- Bespoke aviation driver training developed in-house
- Deep experience operating in high-risk HSSE airside environments
- Proven Emergency Response System with live exercises and specialist response partners
- Continuous visibility of vehicle movements, delivery sequencing and airside access
- Structured escalation and major incident planning, not reactive response
SAF can introduce additional fragility into supply chains. Maintaining continuity in this environment requires scale, coordination and planning. Oxalis Logistics delivers this through:
- Over 461,000 deliveries per annum
- 24/7 Control Centre oversight handling more than 1,200 customer interactions per day, with a Business Continuity Plan that avoids any disruption
- Multi-terminal flexibility and contingency planning
- Cross-trained driver network enabling rapid response to disruption
Aviation fuel logistics operates across multiple high-risk interfaces, from terminal to tanker, to fuel farm to apron. Each hand-off introduces potential risk.
Oxalis Logistics manages this through disciplined execution at every stage, including:
- Precise time-slot adherence aligned to airport operations
- Clear escalation pathways between drivers, control teams and airport stakeholders
- Consistent procedural discipline at all transfer points
- Proven ability to operate within constrained terminal and blending environments
With SAF, risk increasingly sits in documentation and compliance. Oxalis Logistics embeds this into operations through:
- Live management of Certificates of Quality and Proof of Sustainability
- Full chain-of-custody control and batch traceability
- Alignment between physical delivery and sustainability reporting
- Established SHEQ systems with audited processes and recognised accreditations
Ultimately, SAF integration depends on trust in the logistics operator as much as the fuel itself. Oxalis Logistics provides this assurance through:
- More than 5 million litres of SAF delivered across high-profile operations
- Zero recorded service failures on aviation contracts
- Long-standing airport relationships spanning decades, including over 25 years as an into-plane operator at Dublin Airport
- Forward planning with customers to align resources to demand, typically forecast 6 months in advance and refined as requirements evolve
- Close alignment to customer lifting requirements, with proactive communication where supply constraints arise
- A resilient, airport-cleared driver network ensuring consistent driver coverage and continuity of supply
The future of SAF logistics
SAF is no longer a future concept. It is already reshaping aviation fuel supply chains across the UK and Europe.
However, the industry’s success will not be determined by production targets alone. It will depend on whether logistics infrastructure, transport capability and operational resilience can scale alongside demand.
The transition to SAF logistics is ultimately a systems challenge. Fuel production, storage, blending, transport, documentation and delivery all need to evolve together. Choosing the right logistics partner will become increasingly important as operational pressure intensifies.
At Oxalis Logistics, our experience across aviation fuel logistics, Bulk Gas Logistics and safety-critical operations means we are already helping customers navigate that transition today, supported by our wider sustainability strategy.
