Bergen, Norway – [11-Dec-2025]
Aragon (part of Seatrium Group) is proud to announce the award of a major contract by SLB Capturi to supply its Condensia™ CO₂ Liquefaction and Purification System for the Hafslund Celsio’s Oslo CCS Project, delivered by Aker Solutions and SLB Capturi and located at Klemetsrud in Oslo, Norway. This milestone reinforces Aragon’s position as a leading provider of advanced carbon capture and utilisation technologies and marks a significant step toward achieving Europe’s decarbonisation goals.

The Condensia™ system will ensure ultra-pure liquid CO₂ that meets stringent Northern Lights specifications, a critical requirement for safe transport and permanent storage. Northern Lights is the world’s first open-access, full-scale CO₂ transport and storage network, designed to enable industrial emitters across Europe to permanently store captured CO₂ in geological formations beneath the North Sea. Phase one is operational, and phase two will expand capacity from 1.5 million to 5 million tonnes per year, making it a cornerstone of Norway’s Longship programme and Europe’s net-zero ambitions.

CEO Statement – Kristian Utkilen, Aragon
“Winning this contract is a testament to our team’s dedication and innovation. Condensia™ represents the future of CO₂ liquefaction—combining efficiency, reliability, and compliance with Northern Lights’ rigorous specifications. By leveraging Aragon’s advanced process technologies together with SLB’s intellectual properties and proven expertise, we are creating a foundation for common success. This collaboration is not just about technology; it’s about trust and shared ambition to accelerate Europe’s transition to net zero.”

Technical Highlights of Condensia™

1. Ultra-Pure CO₂ Output: Meets Northern Lights specification
2. Energy Efficiency: Proprietary Technology reduces energy consumption compared to conventional systems.
3. Minimal CO₂ Loss: Advanced Deep Condensation Recovery ensures less than 0.1% CO₂ loss during liquefaction.
4. Modular Design: Scalable units for onshore and offshore applications, enabling rapid deployment and integration into existing CCS infrastructure.

Aragon’s Condensia™ platform delivers cutting-edge liquefaction and purification capabilities. Combining Aragon’s advanced process technologies with SLB Capturi’s carbon capture technology, ensures not only compliance with Northern Lights’ stringent specifications but also provides a foundation for rapid deployment and scalability in carbon capture and storage for the waste-to-energy industry. With this delivery, Aragon is delivering solutions that are reliable, cost-effective, and ready to scale across Europe’s decarbonisation landscape.

About Northern Lights
Northern Lights is a joint venture between Equinor, Shell, and TotalEnergies, forming part of Norway’s Longship CCS programme. It provides an open-access infrastructure for CO₂ transport and storage, enabling emitters across Europe to permanently store captured CO₂ in geological formations beneath the North Sea. The project is pivotal for Europe’s net-zero strategy and is supported by significant government funding and international collaboration.

About Aragon
Aragon is a technology leader in carbon capture, purification, and liquefaction solutions. Its Condensia™ platform offers scalable, energy-efficient systems for onshore and offshore applications, ensuring compliance with the most demanding CO₂ specifications for storage and utilisation.

About Hafslund Celsio
Hafslund Celsio is the owner and operator of Norway’s largest waste-to-energy plant at Klemetsrud in Oslo. The Oslo CCS project is retrofitting a carbon capture facility capturing approximately 350,000 tonnes of CO₂ annually. The captured CO₂ will be liquefied, temporarily stored, and shipped from Oslo harbour to the Northern Lights terminal at Øygarden, before permanent storage under the North Sea seabed. SLB Capturi, in collaboration with Aker Solutions, has been awarded the EPCIC contract for the carbon capture plant at Hafslund Celsio’s site.
