Rolls-Royce SMR and Equilibrion will assess nuclear-powered SAF production using small modular reactors, targeting more than 160 million litres per reactor annually
Nuclear-powered e-SAF could meet roughly one third of the UK’s 2040 power-to-liquids aviation fuel target
The initiative aims to address aviation’s growing emissions challenge while supporting domestic fuel production, energy security, and high-skilled job creation
Rolls-Royce SMR and nuclear technology developer Equilibrion have launched a joint assessment to examine how small modular reactors could power large-scale production of Sustainable Aviation Fuel, a step aimed at tackling one of aviation’s most difficult decarbonisation challenges.
The companies have signed a Memorandum of Understanding to conduct a technical and economic evaluation of using nuclear energy to produce synthetic aviation fuel through Equilibrion’s Eq.flight system. The collaboration brings together Rolls-Royce’s factory-built small modular reactor technology with Equilibrion’s modular fuel production platform, which converts electricity and heat into synthetic aviation fuels through power-to-liquids processes.
If deployed at scale, a single Rolls-Royce SMR facility could support the production of more than 160 million litres of Sustainable Aviation Fuel annually, equivalent to roughly one third of the United Kingdom’s projected 2040 power-to-liquids SAF requirement.
Nuclear Energy Meets Aviation Decarbonisation
Aviation remains one of the fastest-growing sources of global greenhouse gas emissions. Despite growing policy momentum, Sustainable Aviation Fuel currently accounts for less than one percent of global aviation fuel consumption.
Governments and airlines increasingly view synthetic fuels as a critical pathway to reduce emissions from long-haul aviation where electrification remains impractical. However, the process requires vast volumes of reliable low-carbon energy.
Small modular reactors could help fill that gap.
Rolls-Royce’s SMR technology is designed to generate consistent heat and electricity suitable for industrial processes such as hydrogen production and synthetic fuel synthesis. Unlike intermittent renewable sources, nuclear reactors can provide stable output around the clock, an important factor for industrial-scale fuel production.
“Our SMR technology is designed to provide clean, affordable and dependable low-carbon energy, exactly the qualities required to unlock large-scale Sustainable Aviation Fuel production,” said Alan Woods, Director of Strategy and Business Development for Rolls-Royce SMR. “The technical and economic assessment completed with Equilibrion will enable them to demonstrate how nuclear can power one of the most ambitious decarbonisation challenges in aviation.”
Meeting UK SAF Mandates
The partnership comes as the UK government accelerates efforts to build domestic Sustainable Aviation Fuel capacity.
Under the UK’s SAF mandate, aviation fuel suppliers will be required to blend increasing volumes of low-carbon fuels into jet fuel supplies, reaching 22 percent by 2040. Meeting that target will require significant expansion of production capacity and substantial investment in low-carbon energy infrastructure.
Equilibrion’s Eq.flight technology is designed to produce e-SAF at commercial scale with lower lifecycle emissions than many existing synthetic fuel approaches. The system converts low-carbon electricity and heat into hydrogen and synthetic hydrocarbons through power-to-liquids processes.
By pairing Eq.flight production facilities with nuclear power, developers believe the system could deliver consistent fuel output while reducing energy input requirements.
The project has already received support from the UK Department for Transport through its Advanced Fuels Fund. The funding supports development of a demonstration facility intended to validate the technology’s technical and economic performance by 2030.

Industrial Strategy And Job Creation
Beyond aviation emissions reductions, the partnership is positioned as part of a broader industrial strategy aimed at strengthening the UK’s energy security and manufacturing base.
Large-scale SAF production facilities powered by domestic nuclear energy could reduce reliance on imported aviation fuels while supporting the UK’s emerging nuclear supply chain.
Equilibrion estimates that each Eq.flight facility could generate significant employment across its operational lifetime.
“Aviation will only meet its climate commitments if SAF becomes available in large, dependable volumes,” said Caroline Longman, Director at Equilibrion. “Nuclear-derived fuel production offers the reliability, scalability and low carbon intensity needed to deliver that future. Delivering nuclear-enabled SAF also creates long-term, high-quality employment. Each Eq.flight facility has the potential to generate around 10,000 skilled local jobs over its lifetime.”
Global Implications For Aviation Fuel Supply
The collaboration reflects growing international interest in nuclear-powered industrial decarbonisation.
As governments tighten aviation emissions targets and airlines commit to net-zero pathways, large-scale production of Sustainable Aviation Fuel remains one of the sector’s most urgent challenges. Many proposed facilities depend on massive renewable energy capacity that remains constrained by land availability and grid limitations.
Nuclear reactors, particularly smaller modular designs, are increasingly being explored as an alternative source of reliable low-carbon power for heavy industry.
If the Rolls-Royce SMR and Equilibrion model proves technically and economically viable, it could provide a blueprint for integrating nuclear energy into synthetic fuel production globally.
For policymakers and investors, the partnership highlights a broader shift in climate strategy. Decarbonising aviation will require not only new fuels, but also new energy systems capable of producing them at scale.
