(Técnicas Reunidas) Alby PtX awards Técnicas Reunidas the engineering contract for a sustainable synthetic aviation fuel plant in Sweden. This is the first contract the Spanish company has secured in this Scandinavian country

The industrial scale plant developed by Alby PtX will produce around 66,000 tons of e-SAF (sustainable synthetic aviation fuel) per year from renewable electricity, water and captured carbon dioxide.
The facility, which will incorporate cutting-edge technologies, will thus make a significant contribution to European decarbonization targets.
This FEED (‘front-end engineering design’) contract is conceived to evolve into an EPC (‘engineering, procurement and construction’) contract, thus enabling Técnicas Reunidas to undertake the construction of the plant, once the project developer Alby PtX has taken the final investment decision (FID).
The contract is aligned with one of the main pillars of Técnicas Reunidas’ SALTA Strategic Plan: strengthening the acquisition of contracts focused on engineering and project management services, an area in which it is set to secure contracts worth around 400 million euros over the course of this year.

Técnicas Reunidas has been awarded the design engineering contract for the development of an industrial-scale e-SAF (sustainable synthetic aviation fuel) plant that the company 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 tons of e-SAF per year using a Power-to-Liquid process. By turning renewable electricity, water and captured carbon dioxide into e-SAF, the plant will contribute significantly to Europe’s decarbonization targets.

Under the FEED contract Técnicas Reunidas will be responsible for the engineering integration of the entire production process.

Green hydrogen produced via electrolysis will serve as a key intermediate product. In the facility’s processing core, the hydrogen in combination with carbon dioxide is transformed into a synthetic crude oil before being refined into the final product. The process includes reverse water-gas shifting (eRWGS), Fischer-Tropsch synthesis, hydrocarbon enrichment and associated treatment units. In addition, the design incorporates a naphtha recycling system to maximize carbon utilization, overall process efficiency and the e-SAF production output. The pre-engineering of the proprietary technologies provided by leading licensors packages lay the technical foundation for the FEED phase.

Appointing Técnicas Reunidas is a key milestone in advancing our Alby project towards a final investment decision. The FEED phase will provide the engineering foundation for a plant designed to produce 66,000 tonnes of synthetic aviation fuel per year, supporting aviation’s decarbonisation and establishing Sweden as a producer of sustainable fuels,”, stated Lars Bjørn Larsen, Member of the Board Alby PtX and CEO of Norsk e-Fuel.

In turn, Gonzalo Pardo, Commercial Director of Track& Services at Técnicas Reunidas, emphasized that “this contract award strengthens Técnicas Reunidas’ position as a leading engineering and construction company in the energy transition sector and further consolidates its growing portfolio of sustainable fuels, hydrogen and ‘Power-to-X’ projects across Europe”.

The now signed contract serves as the first step towards the subsequent preparation for an EPC (‘engineering, procurement and construction’) contract. This would enable Técnicas Reunidas to carry out the engineering, procurement, construction, commissioning and start-up of the plant once Alby PtX has reached a positive final investment decision (FID).

With this award, Técnicas Reunidas is expanding its presence in the European market, as this is the first contract the Spanish company has secured in Sweden.

Furthermore, the contract is part of one of the main pillars of the company’s SALTA Strategic Plan: strengthening the acquisition of contracts focused on engineering services and project management. In 2026, Técnicas Reunidas will secure contracts for projects of this type totaling nearly 400 million euros, enabling it to confirm its target of 500 million in the revenues from these kind of activities by 2028.
