From Puregas to Wärtsilä Gas Solutions to Nord Gas Solutions
Mid-August marked a significant milestone as Ireland celebrated the first biomethane injection into its national gas grid using Nord Gas Solutions' biogas upgrading technology. This achievement highlights not only a landmark moment for Ireland's renewable energy transition, but also reflects more than 20 years of experience delivering innovative and reliable biogas upgrading solutions.

For more than two decades, Nord Gas Solutions has been at the forefront of biogas upgrading technology, helping turn renewable biogas into high-quality biomethane for injection into gas grids, industrial use, and the production of liquefied biomethane (bioLNG).
Our story is built on a legacy of innovation and expertise that stretches back over 20 years. While our name has evolved through the years, our commitment to delivering reliable and efficient biogas upgrading solutions has remained unchanged.
A Strong Heritage
Many in the biogas industry will recognize the name Puregas, a pioneer in amine-based biogas upgrading technology. Over the years, that expertise became part of Wärtsilä Gas Solutions, where the technology portfolio continued to evolve and expand, adding Bio-LNG and Bio-CO₂ liquefaction solutions alongside our established upgrading technologies.
At the same time, we became part of a broader organization with world-class expertise in marine, LNG, offshore, and gas handling technologies, delivering solutions such as fuel gas supply systems, cargo handling systems, boil-off gas reliquefaction, and gas processing systems for the energy and maritime industries.
Today, under the name Nord Gas Solutions, we bring these capabilities together, building on a strong foundation of engineering excellence, operational reliability, and customer focus.
The evolution of our company reflects more than a change of name. It represents the continued strengthening of our technology portfolio, expertise, and market presence, enabling us to support our customers across the full gas value chain
Proven Technology, Proven Results
Biogas upgrading is a critical process that transforms raw biogas into biomethane by removing carbon dioxide and other impurities. The result is a renewable fuel that can replace fossil alternatives in transportation, industry, and energy applications.
Over the last 20 years, our technology has been successfully applied in plants across multiple countries and a wide range of applications. This experience has provided invaluable operational knowledge, enabling us to continuously optimize performance, improve efficiency, and support customers throughout the entire lifecycle of their facilities.
Driving the BioLNG Market
As the demand for renewable fuels continues to grow, the combination of biogas upgrading and liquefaction has become increasingly important. Nord Gas Solutions is uniquely positioned to support this development, offering expertise across the entire value chain from raw biogas to liquefied biomethane.
