Stanlow Sustainable Aviation Fuel Project Advances to Next Development Stage

Essar Energy Transition has completed a key early milestone in its plans to develop one of the UK’s largest sustainable aviation fuel (SAF) production facilities at the Stanlow refinery in northwest England.

The company confirmed that the project has successfully completed its Pre-Front End Engineering Design (Pre-FEED) phase, an important stage used to assess the technical and commercial viability of major infrastructure developments before detailed engineering work begins.

The project is now expected to move into the next design and engineering phase later this year, with a final investment decision currently targeted for 2028.

If approved, the facility would produce sustainable aviation fuel using renewable methanol as its primary feedstock. Essar says the plant could manufacture more than 200,000 tonnes of SAF annually, supported by approximately 550,000 tonnes of renewable and bio-based methanol.

The proposed facility would form part of the wider Stanlow refinery complex, allowing the fuel to be integrated into existing fuel blending, storage, and distribution infrastructure already connected to major UK airports.

According to the company, using existing logistics and pipeline networks could reduce the need for additional infrastructure investment while helping accelerate fuel supply to the aviation sector.

The project reflects the growing focus on sustainable aviation fuel as governments and airlines seek practical ways to reduce carbon emissions from air travel.

While electric and hydrogen-powered aviation technologies continue to develop, SAF is currently viewed as one of the most commercially viable short-to-medium-term options for reducing emissions from existing aircraft fleets, particularly on long-haul routes where alternative propulsion technologies remain limited.

The UK government has already introduced long-term targets aimed at increasing the proportion of aviation fuel sourced from sustainable alternatives over the coming decades.

However, scaling up SAF production remains a significant challenge globally. Production volumes are still relatively limited, costs remain higher than conventional jet fuel, and securing reliable feedstock supply chains continues to be a major issue across the sector.

Projects such as Stanlow are therefore becoming increasingly important as the UK attempts to build domestic SAF production capability while supporting wider decarbonisation targets for aviation.

The development also aligns with broader efforts to reposition industrial sites such as Stanlow as part of the energy transition economy.

The refinery complex is already involved in several low-carbon and energy transition initiatives, including hydrogen production, industrial decarbonisation, and alternative fuel projects.

For the aviation sector, increasing domestic SAF production capacity is expected to become increasingly important as airlines face growing regulatory pressure to reduce emissions while maintaining operational flexibility across existing fleets.

Industry analysts continue to view sustainable aviation fuel as a critical transitional technology, particularly during the period before zero-emission aircraft technologies become commercially scalable across wider parts of the market.

As a result, projects capable of producing SAF at industrial scale are likely to play an increasingly important role within both the UK’s energy transition strategy and the future development of lower-carbon aviation infrastructure.
