Carbon Neutral Fuels FlexSAF Project Starling at Workington

New construction · Workington , United Kingdom · FEED / Pre-FID

Where it stands

FEED / Pre-FID

Front-End Engineering Design is underway (FEL-3). Scope and engineering are being firmed up toward a sanction-quality cost estimate (typically ±10–15%). The project is well defined but not yet financially sanctioned — the "pre-FID" phase.

Why we featured this project

14–20 October 2026

Carbon Neutral Fuels has unveiled FlexSAF, a hybrid plant architecture that combines eSAF from biogenic carbon dioxide and green hydrogen with bioSAF from biomethane into a shared Fischer-Tropsch synthesis and upgrading line at Project Starling. The October redesign raises target output from 25,000 to 42,000 tonnes a year through process optimisation that allows flexible switching within equipment limits.

Featured as project of the week on 14 October 2026. The record may have changed since; this is its current state. Subscribers see the full detail on all 2,787 projects.
