Alfa Laval Selected by Saipem to Supply Heat Transfer Technology for Stockholm Exergi’s 800,000-Tonne BECCS Carbon Capture Project in Sweden

(IN BRIEF) Alfa Laval has been selected by Saipem to provide heat transfer equipment for Stockholm Exergi’s BECCS project in Sweden, one of Europe’s largest planned bioenergy carbon capture facilities. Scheduled to begin operations in 2028, the project is designed to capture, liquefy and permanently store up to 800,000 tonnes of biogenic CO₂ annually, equivalent to around 1–2% of current global carbon capture capacity. Alfa Laval will supply its Ziepack gas-gas interchanger and several plate-and-frame heat exchangers as part of the core capture process. The equipment will help recover energy used during CO₂ separation and liquefaction, with recovered heat returned to Stockholm’s district heating system. The project is located at Stockholm Exergi’s biomass-based combined heat and power plant and supports Sweden’s climate-neutrality goals as well as wider EU climate objectives. Stockholm Exergi’s district heating network serves more than 800,000 people and around 400 locations. Saipem is delivering the project under an EPC contract covering the carbon capture facility.

(PRESS RELEASE) LUND, 15-Sep-2026 — /EuropaWire/ — Alfa Laval has been selected by Saipem, the engineering, procurement and construction contractor for Stockholm Exergi’s Bioenergy with Carbon Capture and Storage (BECCS) project, to supply heat transfer equipment for what is expected to become one of Europe’s largest bioenergy carbon capture facilities.

The Stockholm project is scheduled to begin operations in 2028 and is designed to capture, liquefy and permanently store up to 800,000 tonnes of biogenic CO₂ annually. According to Alfa Laval, that volume represents approximately 1–2% of today’s total global carbon capture capacity.

The BECCS facility will be developed at Stockholm Exergi’s biomass-based combined heat and power plant in Stockholm, described as the largest of its kind in Europe. Once operational, the system will capture CO₂ generated from the combustion of biogenic fuels and prepare it for permanent storage.

Alfa Laval’s heat transfer technology will form part of the core capture process, helping maximise energy recovery and overall system efficiency.

The company will supply its Ziepack gas-gas interchanger together with several process plate-and-frame heat exchangers. The equipment has been selected by Saipem as part of its EPC contract for the Stockholm Exergi project.

Thomas Møller, President of the Energy Division at Alfa Laval, said large-scale carbon capture presents demanding thermal engineering requirements and that effective recovery of energy is essential to making such systems commercially viable.

He said Stockholm Exergi is demonstrating how industrial-scale negative emissions can be achieved and that Alfa Laval’s heat transfer technologies will support the project’s efficiency objectives.

Carbon capture and liquefaction require significant amounts of energy. Stockholm Exergi plans to recover much of that energy through the heat exchanger system and return it to the existing district heating network.

Egil Nybakk, Director BECCS at Stockholm Exergi, said the facility will consume substantial energy when separating CO₂ from flue gas and subsequently liquefying it. He said Alfa Laval’s Ziepack heat exchangers will allow that energy to be reclaimed and redirected into Stockholm’s district heating system, creating an additional contribution to the project’s carbon-removal objectives.

The project is designed around Bioenergy with Carbon Capture and Storage, a carbon-removal approach that combines renewable energy generation from biomass with the capture and permanent storage of the resulting biogenic CO₂.

Unlike conventional carbon capture systems focused primarily on reducing fossil emissions, BECCS can create net-negative emissions because the carbon absorbed by biomass during growth is subsequently captured rather than returned to the atmosphere.

At BECCS Stockholm, captured CO₂ will be compressed and liquefied to enable efficient transportation and permanent storage in suitable underground or offshore geological formations.

The project forms part of Sweden’s broader climate-neutrality ambitions and supports European Union climate objectives. Stockholm Exergi aims to position the facility among the world’s largest installations dedicated to permanent removal of biogenic carbon dioxide.

Heat integration will play an important role in the project’s efficiency. Alfa Laval’s equipment will be used to recover thermal energy from parts of the capture and liquefaction process and make that energy available elsewhere in the system, including Stockholm’s district heating network.

Stockholm Exergi’s district heating system currently serves more than 800,000 people and approximately 400 locations in Stockholm, connecting customers with the company’s heating and cogeneration plants.

Saipem, meanwhile, is responsible for the project’s EPC activities and operates across the broader carbon capture value chain, including capture, transportation and storage infrastructure.

The contract adds another large-scale carbon capture application to Alfa Laval’s energy-transition portfolio. The company provides technologies in heat transfer, separation and fluid handling and works across industries including energy, food, water, pharmaceuticals, maritime transport and offshore operations.

Alfa Laval was founded more than 140 years ago and has customers in over 100 countries. The company employs more than 23,500 people and reported annual sales of SEK 69.6 billion, equivalent to approximately €6.6 billion, in 2025. Alfa Laval is listed on Nasdaq Stockholm.

By supplying heat recovery technology to the Stockholm Exergi BECCS facility, Alfa Laval will support one of Europe’s largest planned carbon-removal projects while helping reduce the energy intensity of the capture process and recover usable heat for Stockholm’s existing energy infrastructure.

This is Alfa Laval   
Working closely with customers and partners worldwide, Alfa Laval challenges conventional thinking on engineering, quality, and innovation. Together, driving the solutions of the future, inspiring progress towards a more resourceful, less wasteful world.

About the Stockholm Exergi BECCS project

Bioenergy with Carbon Capture and Storage (BECCS) is a key climate technology that generates renewable energy from biomass while capturing and permanently storing the resulting CO2.

The Stockholm Exergi plant, BECCS Stockholm, is expected to capture and permanently store up to 800,000 tonnes of biogenic CO₂ annually, making it one of the world’s largest carbon removal facilities.The captured CO2 is then compressed and liquified, allowing for space-efficient underground or offshore storage.
