Costain's Northern Endurance Contract Drives 25.7% Energy Revenue Rise as CCS Delivery Gap Widens
Northern Endurance Partnership work lifted Costain's energy revenues 25.7% in the first half, as UK CCS storage capacity trails near-term European targets by a wide margin.
The Northern Endurance Partnership's first phase in Teesside is built to store 1.5 million tonnes of CO2 per year. A second phase is intended to reach at least 5 million tonnes annually from 2028, in part supported by Stockholm Exergi's planned biogenic CO2 volumes. The EU alone is targeting at least 50 million tonnes of annual storage capacity by 2030. Scale the ambition further and modelling cited in analysis published Monday (2026-08-17) puts captured CO2 volumes at roughly 280 million tonnes per year by 2040 and around 450 million tonnes by 2050.3
The distance between NEP Phase 1's 1.5 million tonnes and that 50 million tonne annual target frames the execution challenge facing every project in the current pipeline. British engineering contractor Costain found commercial traction in that gap: energy revenues climbed 25.7% to £37.2m in the first half of 2026, with the Teesside carbon capture contract among the primary drivers, according to its half-year results published Thursday (2026-08-13). Group revenues rose 3.4% to £543.1m over the same period, a pace the energy segment ran well ahead of.2,3
The East Coast Cluster, of which Northern Endurance is the storage component, and HyNet in the North West together secured eligibility for up to £21.7bn of government support through the UK's Track 1 cluster sequencing scheme, according to Energy Pathfinder data published in late May (2026-05-29). The North Sea Transition Authority followed that with a tender for offshore infrastructure, seeking provision of two guard vessels worth up to £25m combined, each required to operate for 73 days including mobilisation and demobilisation phases.1
Costain said it is working on further expansion into the energy sector. Its energy division's 25.7% revenue growth ran roughly seven times the pace of the company's overall top-line increase. That ratio indicates how quickly government-backed low-carbon contracts are becoming a material rather than peripheral revenue source for UK engineering firms.2
The project's phased structure carries its own commercial logic. Phase 1 at 1.5 million tonnes provides proof of concept at a scale governments and operators can absorb. Phase 2, targeting at least 5 million tonnes from 2028, requires a deeper pipeline of emitters willing to commit their CO2 volumes over multi-year contracts. Stockholm Exergi's planned biogenic output is cited as one anchor, but the model depends on others following.3
Analysis published by oilprice.com on Monday (2026-08-17) observed that carbon capture continues to be debated as if technical performance were the decisive question: whether solvents remove CO2, whether compression and injection work, whether underground storage holds. Those questions matter, the analysis noted, but they no longer fully explain why project timelines move as they do. Costain's half-year results offer one data point from the execution side of that debate.3
The government's £21.7bn support envelope represents committed eligibility rather than contracted engineering spend. But its conversion into live project contracts over the next two to three years will shape how quickly a wider group of UK contractors begins to see carbon capture revenues comparable to Costain's current gains.1
The guard vessel tender, worth up to £25m for two vessels operating 73 days each, is a near-term and specific test of the offshore supply chain for NEP. Its award will indicate whether the project's offshore infrastructure timetable is holding and whether smaller contract lots are drawing competitive bids in a market where larger engineering firms have already claimed the anchor packages.1
Phase 2's expansion to at least 5 million tonnes annually from 2028 is the harder milestone. It requires volume commitments from emitters that have not yet been publicly confirmed beyond the biogenic CO2 partnership cited in the Monday (2026-08-17) analysis, leaving the project's second phase dependent on a contracting process that is still underway.3
