Offshore Carbon Storage Moves From Concept to Commerce

Northern Lights expansion locks in 5M-tonne capacity by 2028, cementing Europe’s move from pilot projects to full-scale carbon storage

5 Feb 2026

In the North Sea, carbon dioxide is starting to look less like waste and more like cargo. Europe’s offshore carbon-storage industry, long stuck in pilot mode, is edging into something sturdier. At the centre of this shift sits Norway, and a project called Northern Lights.

In March 2025 Northern Lights, a joint venture between Equinor, Shell and TotalEnergies, took a final investment decision to expand its capacity sharply. By around 2028 it aims to store more than 5m tonnes of CO₂ a year, up from roughly 1.5m today. The expansion is backed by European infrastructure funding and long-term contracts, the ingredients needed to move from demonstration to business.

This matters because Europe’s climate rules are tightening faster than many heavy industries can adapt. Cement, steel and waste-to-energy firms face emissions they struggle to eliminate. Offshore storage, shared across borders, offers a way to comply without shutting down. Northern Lights is no longer asking whether carbon can be stored safely under the seabed. It is betting that customers will pay to do so at scale.

They already are. Deals such as the agreement with Stockholm Exergi, which plans to capture biogenic CO₂ and ship it to Norway for permanent storage, show rising confidence in cross-border solutions. Such contracts help anchor investment and reduce dependence on public subsidy, a weakness that has dogged earlier schemes.

The partners present the expansion as part of a wider European network, with pipelines and ships moving carbon from inland factories to offshore hubs. Centralising storage should lower costs and speed adoption, much as shared gas infrastructure once did.

The knock-on effects are spreading through the offshore supply chain. SLB, an oilfield-services firm, has won work on the next phase, a sign that skills built in hydrocarbons are being repurposed rather than retired. Analysts see this less as a detour than as a gradual shift in the industry’s centre of gravity.

Capacity, however, remains scarce, and competition is growing. Early access to mature sites may prove decisive for firms under regulatory pressure. Still, the direction is clear. With Norway’s head start, EU backing and rising industrial demand, Europe’s offshore carbon market is beginning to take shape, quietly, contract by contract.
