Valmet Chosen for Finland's First CO₂ Liquefaction Plant Automation Project

A new carbon capture project in Finland is turning biogas emissions into reusable CO₂, with automation playing a key role in the plant’s operation. The facility will be built at Auris Energia’s biogas site in Mäntsälä, where Suomen Biovoima Oy is developing the technology.

The Finnish project represents an important step towards capturing and reusing carbon emissions instead of releasing them into the atmosphere. In this approach to circular economy initiatives, the plant will recover CO₂ for applications such as concrete production, where it can be permanently bound within building materials.

Valmet has been chosen to provide the automation system for the new CO₂ liquefaction plant. The company’s DNAe Distributed Control System is designed to automate and monitor plant operations from a remote location.

The automation platform will enable Auris Energia to optimize energy use, raw material efficiency, and minimize manual intervention through automated process controls. Secure data transfer, monitoring, reporting, and performance tracking are all part of the system.

According to Suomen Biovoima’s sales manager Mikko Bengts, ‘Capturing and utilizing CO₂ allows us to turn emissions into a valuable resource while improving overall efficiency.’ The partnership with Valmet enables them to integrate modern automation solutions into their projects and scale these innovations in future endeavors.

The project will be implemented in phases. The primary automation system is set for delivery in November 2026, installation planned for December of that year, and startup anticipated during the first quarter of 2027. However, financial details regarding the contract were not disclosed.

Valmet’s senior sales manager Matti Miinalainen noted that ‘This project showcases how automation can support both environmental sustainability and business performance.’ The company will continue to upgrade the system and offer lifecycle services to maintain optimal plant operation over time.

The CO₂ liquefaction plant in Finland is expected to be the first of its kind, capturing, purifying, and liquefying CO₂ produced during biogas generation for industrial reuse. It sets a precedent for future projects aiming to minimize carbon emissions.
