As summer approaches, the looming threat of jet fuel shortages casts a shadow over holiday plans across the UK. Industry leaders warn that current refinery capacities and supply chain challenges could disrupt air travel, raising urgent questions about the nation’s ability to secure sufficient aviation fuel during peak travel seasons.
Current Challenges in UK Jet Fuel Supply
Jonathan Hinkles, CEO of Skybus, highlights a critical concern: “Do we need more resilience from a homegrown perspective in terms of our capacity in the UK to be able to refine a higher proportion of our fuel?” This question strikes at the heart of the UK’s dwindling refinery infrastructure. Over recent years, the UK has seen a significant reduction in its oil refining capabilities, with only four refineries remaining operational, including the ExxonMobil-owned Fawley refinery in Hampshire.
These facilities have already been directed to prioritise jet fuel production amid rising demand. However, as Amaar Khan explains, ramping up output is not a quick fix: “This doesn’t happen overnight, and doesn’t result in a significant increase in jet fuel output.” Refining jet fuel requires precise processes and capacity that cannot be expanded rapidly, especially given the limited number of operational refineries.
Consequently, the UK remains heavily reliant on imported jet fuel, much of which comes from geopolitically sensitive regions. This dependence exposes the country to supply chain disruptions and price volatility, especially as global demand for aviation fuel recovers post-pandemic.
The Promise and Challenges of Sustainable Aviation Fuel (SAF)
One potential solution gaining traction is the increased production and use of Sustainable Aviation Fuel (SAF). SAF is a synthetic fuel made from renewable sources such as waste cooking oil, agricultural residues, dedicated energy crops, or through advanced processes converting water and carbon dioxide into e-fuels. Its defining advantage lies in its significantly lower carbon footprint compared to conventional fossil-based jet fuel.
Both the UK and the European Union have established ambitious mandates to scale SAF usage over the next 25 years, aiming to reduce aviation’s environmental impact while enhancing energy security. Despite these goals, the industry is still in its infancy. Currently, SAF availability is limited, expensive—trading at a premium of over $1,000 per tonne compared to traditional jet fuel—and largely imported from East Asia.
Jonathan Hinkles remains cautiously optimistic: “It really becomes a question of; can you actually get SAF? Can we scale up production of SAF at a meaningful rate in the UK or Europe to take over an increasing proportion of jet fuel supply?” The transition to SAF depends on overcoming significant production, infrastructure, and cost barriers.
Environmental advocates echo this cautious optimism. Tom Taylor, UK policy manager for the lobby group Transport and Environment, acknowledges that “Increasing SAF production won’t eliminate jet fuel imports overnight.” However, he stresses the strategic importance of the shift: “By scaling it up, we can move the source of aviation fuel from geopolitically sensitive fossil fuels to locally managed renewable grids and waste streams.”
Why Jet Fuel Security Matters for UK Travelers
The UK’s ability to secure consistent jet fuel supplies directly influences the reliability and affordability of air travel. Summer holidays, a cornerstone of British culture and economy, could face disruption if jet fuel shortages worsen. Airlines may be forced to reduce flight frequencies or increase ticket prices, affecting millions of travelers and the broader tourism industry.
Moreover, geopolitical tensions and supply chain vulnerabilities underscore the need for a more resilient and sustainable fuel strategy. By investing in domestic refining capacity and accelerating SAF production, the UK can reduce dependence on volatile international markets and contribute to global climate goals.
Looking Ahead: Building a Resilient Aviation Fuel Future
The path forward requires coordinated efforts from industry, government, and environmental stakeholders. Expanding refinery capabilities is a complex, capital-intensive task with long lead times, but necessary to enhance fuel security. Simultaneously, scaling SAF production offers a promising avenue to reduce carbon emissions and localize fuel supply.
Innovation in synthetic fuels, supportive policies, and investment in renewable energy infrastructure will be critical to overcoming current barriers. As the aviation sector rebounds, balancing environmental commitments with operational realities remains a formidable challenge.
For UK travelers, the interplay between fuel availability and sustainable alternatives will shape the future of summer holidays. The urgency to address these issues grows as demand surges, underscoring the importance of resilient, eco-friendly aviation fuel solutions.
In summary, the UK faces a pivotal moment in securing jet fuel supply and transitioning to sustainable alternatives. Strengthening domestic refining capacity and scaling SAF production are essential steps to safeguard the nation’s summer travel season and meet long-term climate targets. The coming years will reveal whether these strategies can deliver a stable, greener future for UK aviation.
