UK launches second offshore CO₂ storage licensing wave to cement North Sea as Europe’s decarbonisation hub

The United Kingdom has opened a second offshore carbon dioxide (CO₂) storage licensing round that extends the industrial decarbonisation architecture of the North Sea through mid-century, offering a belt of capacity intended to anchor long‑term emissions reductions for heavy industry at home and in Europe.

According to the original report, the North Sea Transition Authority (NSTA) has offered 14 new offshore geological storage zones off the coasts of Scotland and England, bringing the programme’s cumulative potential to roughly 2 gigatonnes (Gt) of CO₂ when combined with the first wave of licences awarded in 2023. Applications are open until March 2026, with awards expected in early 2027. The move aims to create a north–south storage corridor , centred on Endurance and Liverpool Bay from the initial round , that could service industrial clusters and cross‑border demand for long‑term storage.

Established energy companies and existing Track‑1 cluster participants are positioned to dominate development. Industry data shows BP, Equinor and Eni, already active in early projects, are expected to feature prominently in this second phase, while operators such as EnQuest, Harbour Energy and Shell are seeking to repurpose depleted petroleum fields and leverage existing infrastructure. The NSTA’s earlier rounds awarded licences to BP and Equinor for Southern North Sea sites with the potential to store up to 23 million tonnes per year by the late 2030s, underscoring continuity between rounds and the regulator’s long‑term programme. The licensing framework also revisits areas first offered in the 2022 launch of the UK’s initial carbon storage tender, which included both saline aquifers and exhausted hydrocarbon reservoirs.

For industrial emitters , cement, steel, chemicals and other heavy sectors , the expanded portfolio improves visibility around capacity and the bankability of long‑term CO₂ offtake arrangements. Securing licensed storage is likely to be a precondition for capital‑intensive decarbonisation projects and could support offtake tenors beyond 15 years, thereby reducing exposure to volatile carbon prices and regulatory uncertainty.

However, the economics underpinning carbon capture and storage (CCS) remain challenging. The NSTA and market observers note a substantial mismatch between current market signals and full system costs: UK Emissions Trading Scheme allowances are trading in the mid‑tens of pounds per tonne, while comprehensive CCS chain costs are estimated in the region of $130–$150/t. Bridging that gap will require material public support and regulated revenue models , examples cited include Contracts for Difference (CfD) or Regulated Asset Base (RAB)‑style mechanisms , as well as direct subsidies for capture, transport and storage infrastructure.

Operational delivery will depend on multi‑agency coordination. The NSTA issues storage licences, but seabed leases from The Crown Estate remain necessary and coastal planning and marine‑use coexistence constraints , notably with offshore wind developments , will shape site selection, timing and engineering solutions. Parliamentary scrutiny of delays in early Track‑1 projects has added political impetus to the timetable; the second licensing wave signals continued policy commitment to maintain activity in a transitioning offshore sector.

Strategically, the UK intends to position the North Sea as a CO₂ storage hub for continental Europe. That ambition places it in direct competition with other North Sea projects such as Norway’s Northern Lights, Denmark’s Greensand and the Dutch Porthos initiative. The UK’s geological endowment is large , industry estimates exceed 78 Gt of theoretical capacity , but commercial attractiveness will be determined by regulatory alignment across Europe, the treatment of cross‑border CO₂ flows under mechanisms such as the EU’s Carbon Border Adjustment Mechanism, and the practicalities of transporting CO₂ from industrial centres to offshore reservoirs.

The licensing expansion has implications across the supply chain. For offshore service and engineering firms, the extended pipeline offers multi‑decade opportunities to redeploy skills and assets from oil and gas into CCS operations, helping to partially offset declining hydrocarbon activity. For operators, the ability to repurpose existing wells and platforms can lower development cost and shorten mobilisation timelines, although detailed site characterisation, seismic surveys and appraisal drilling , activities already signalled in earlier NSTA awards , will be essential before storage permits and full‑scale injections can proceed.

Industry observers caution that announced capacity materially outstrips the UK’s near‑term capture targets of 20–30 million tonnes per annum by 2030. Authorities acknowledge that those targets will not be met in the short term but defend early licensing as a strategic leverage: securing storage capacity now is intended to underpin investment in capture infrastructure over the 2030s and 2040s and to guarantee options for emitters seeking durable disposal routes to 2050.

For corporate and public planners focused on industrial decarbonisation, the second licensing wave clarifies the direction of travel while underlining two stark realities: geological capacity alone does not create a market, and long‑term, credible revenue frameworks , coupled with cross‑agency permitting and maritime‑use coordination , are prerequisites for converting licence areas into operational storage volumes. The success of the UK’s ambition to become a North Sea storage hub will therefore rest on the interaction of technical appraisal, commercial contracting and continued policy support to close the gap between capture costs and achievable revenues.
