SLB OneSubsea wins contract for Northern Lights phase two CO2 project

SLB OneSubsea, a joint venture backed by SLB, Aker Solutions, and Subsea7, has secured an engineering, procurement and construction (EPC) contract from Equinor for the second phase of the Northern Lights CO₂ storage project offshore Norway.

The contract covers the delivery of two satellite subsea CO₂ injection systems and related tie-in infrastructure. Initial equipment deliveries are scheduled for 2026.

This latest award builds on the successful completion of two similar injection systems for the project’s first phase in 2023.

Northern Lights is a key part of the world’s first full-scale, open-access carbon capture and storage (CCS) value chain, encompassing CO₂ capture, transport, and permanent offshore storage.

As of May 2025, Northern Lights has obtained all necessary permits to begin injecting CO₂ into the Aurora storage site in the North Sea. The first phase of development is fully complete, with capacity booked by industrial customers. Operations are expected to commence in the second half of 2025.

The decision to proceed with phase two followed a commercial agreement with an industrial end-user, enabling project partners—TotalEnergies, Shell, and Equinor—to greenlight further investment. The expansion will raise annual CO₂ storage capacity from 1.5m to at least 5m tonnes.

“The Northern Lights project is pivotal for Europe’s path toward net-zero emissions, and it is well aligned with our own strategy to expand the frontiers of subsea for a sustainable energy future,” said Mads Hjelmeland, CEO of SLB OneSubsea.
