- FEED verification for the Lysekil refinery conversion starts in August 2025.
- The EPCm phase is expected to begin in early 2026, pending investment decision.
- The project will shift production to renewable diesel and sustainable aviation fuel.
- The conversion could cut CO2 emissions by 2-3 million tonnes annually.
Project Overview
Worley has been contracted by Preem for FEED verification to convert the ICR plant at the Lysekil refinery in Sweden. The project will transition the plant from conventional diesel production to renewable diesel and sustainable aviation fuel.
Timeline and Phases
The FEED verification is set to commence in August 2025. The contract includes a potential transition into the Engineering, Procurement, and Construction Management (EPCm) phase, expected to start in early 2026, contingent on Preem's final investment decision.
Production Shift
The Lysekil plant, currently focused on traditional diesel, will be repurposed to produce renewable fuels using vegetable and animal oils/fat. This marks a significant move away from fossil-based production.
Environmental Impact
The refinery conversion is projected to reduce annual emissions by 2–3 million tonnes of CO2e at the end-user level and by approximately 200,000 tonnes of CO2e annually at the refinery itself.
