Alby PtX Awards Técnicas Reunidas FEED Contract for 66,000 tpy e-SAF Plant in Sweden

Técnicas Reunidas has been awarded the design engineering contract for an industrial-scale e-SAF plant that Alby PtX plans to build in the town of Alby, in the Swedish municipality of Ånge. The plant is designed to produce around 66,000 tpy of e-SAF, a sustainable synthetic aviation fuel, using a Power-to-Liquid process that converts renewable electricity, water and captured carbon dioxide into fuel.

Under the FEED contract, Técnicas Reunidas is responsible for the engineering integration of the entire production process. Green hydrogen produced via electrolysis serves as a key intermediate product. In the processing core, the hydrogen is combined with carbon dioxide and transformed into a synthetic crude oil, which is then refined into the final product. The process includes reverse water-gas shifting (eRWGS), Fischer-Tropsch synthesis, hydrocarbon enrichment and associated treatment units, and the design incorporates a naphtha recycling system to maximise carbon utilisation.

Lars Bjørn Larsen, Member of the Board of Alby PtX and CEO of Norsk e-Fuel, called the appointment a key milestone toward a final investment decision (FID). Gonzalo Pardo, Commercial Director of Track & Services at Técnicas Reunidas, said the award strengthens the company's position in the energy transition sector and its portfolio of sustainable fuels, hydrogen and Power-to-X projects across Europe.

The signed contract is the first step toward a subsequent engineering, procurement and construction (EPC) contract, covering engineering, procurement, construction, commissioning and start-up of the plant once Alby PtX reaches a positive FID. It is the first contract the Spanish company has secured in Sweden. The award also forms part of one of the main pillars of its SALTA Strategic Plan: strengthening the acquisition of contracts focused on engineering services and project management. In 2026, Técnicas Reunidas expects to secure contracts of this type totalling nearly €400 million.

A FEED award is an early, relatively low-cost stage in a Power-to-Liquid project. It fixes the process configuration and the engineering basis on which cost estimates are built, but it commits neither the owner nor the contractor to construction. For e-SAF developers, this staging is how projects move toward financing: the engineering has to be mature enough for lenders and equity partners to judge before a capital decision is taken.

For the supply side of sustainable aviation fuel, the relevant distinction is between plants that hold design contracts and plants that are funded and under construction. A 66,000 tpy facility is a design on paper until a positive FID is reached, so announced capacity of this kind should be read as pipeline rather than as fuel available to operators.

The next milestone the announcement itself names is Alby PtX's FID. A positive decision would open the way to the EPC contract, and that conversion from FEED to EPC is the point at which the award would turn into construction work for Técnicas Reunidas.
