Wärtsilä to supply Andion Scandinavia AB with bioLNG solution
Wärtsilä Gas Solutions, part of technology group Wärtsilä, has been selected to deliver a complete bioLNG solution for a new biogas plant in Eskilstuna, Sweden. The contract has been signed with Andion Scandinavia AB, which will serve as the main supplier in a design and build contract with project owner Eskilstuna Biogas AB, providing both biogas upgrading and liquefaction solutions.
Project Capacity and Scope
Once operational, the facility will be capable of producing up to 17 tonnes per day of bioLNG from organic waste. The order was booked by Wärtsilä in the second quarter of 2025, adding to the company’s portfolio of renewable energy projects.
Wärtsilä Gas Solutions will engineer, manufacture, install, and commission the complete bioLNG solution for the Eskilstuna Biogas AB facility. The scope includes a 200-cubic-metre storage tank and export station, with provision for potential future installation of a CO2 liquefaction unit. A spare parts package and service agreement will follow the initial delivery.
Strategic Vision for Net-Zero Carbon Future
Martin Kambler, managing director of Eskilstuna Biogas AB, articulated the company’s commitment to enabling a net-zero carbon future through the utilisation of organic waste to produce clean energy. He characterised the bioLNG plant as a significant milestone in the organisation’s portfolio and expressed satisfaction with Wärtsilä’s experience and capabilities supporting the project.
BioLNG Production Process and Applications
BioLNG is produced through a two-stage process that first upgrades biogas by removing hydrogen sulphide, carbon dioxide, and water vapour before liquefying the purified gas at minus 160 degrees Celsius. The resulting fuel possesses the same calorific value and properties as conventional fossil-based LNG, making it a viable and environmentally sustainable replacement fuel for applications currently using conventional liquefied natural gas.
This equivalence in technical properties enables bioLNG to serve as a drop-in replacement fuel without requiring modifications to existing LNG-compatible equipment and infrastructure, facilitating adoption across transportation, maritime, and industrial applications.
Industry Leadership in Decarbonization
Rolf Håkansson, sales manager for Biogas at Wärtsilä Gas Solutions, positioned the company’s bioLNG solutions as central to Wärtsilä’s decarbonisation strategy. He noted that the company’s track record of successful installations has established a leading position in the bioLNG field.
Håkansson emphasised that this latest order reinforces Wärtsilä’s commitment to providing solutions that support a 100 percent renewable energy future whilst exemplifying how the company actively contributes to the global transition towards cleaner fuels. The contract demonstrates the commercial viability of converting organic waste streams into transportation-grade renewable fuels at meaningful scale.
Role of Andion Scandinavia
Andion Scandinavia AB’s involvement as main supplier brings project management and integration capabilities to the development, coordinating delivery of biogas upgrading and liquefaction systems within a unified design and build framework. This approach streamlines project execution and provides Eskilstuna Biogas AB with a single point of accountability for the complete facility.
Circular Economy and Waste Valorization
The Eskilstuna project represents practical implementation of circular economy principles, transforming organic waste materials into valuable energy products. By diverting organic waste from disposal whilst producing renewable fuel, the facility addresses both waste management challenges and energy sector decarbonization objectives.
The daily production capacity of 17 tonnes of bioLNG provides significant renewable fuel supply for regional transportation and industrial applications, contributing to Sweden’s climate objectives and supporting development of renewable fuel infrastructure.
Market Context and Technology Deployment
The project reflects growing commercial deployment of bioLNG production technology as municipalities, waste management entities, and energy companies seek to monetize organic waste streams whilst delivering renewable alternatives to fossil fuels. Sweden’s supportive policy framework for renewable fuels and established biogas industry provide favorable conditions for such investments.
Wärtsilä’s selection for the Eskilstuna project demonstrates the company’s established position in bioLNG technology supply, with proven systems and project execution capabilities that reduce technical risk for project developers. The inclusion of provisions for future CO2 liquefaction capacity indicates potential for additional revenue streams from captured carbon dioxide, further enhancing project economics.
The facility will join Sweden’s growing network of biogas and bioLNG production sites, strengthening the country’s renewable fuel infrastructure and supporting decarbonisation of transportation sectors that are difficult to electrify, including heavy-duty road transport, maritime shipping, and long-haul logistics operations.
