Spirit Energy has reached a regulatory milestone for the Morecambe Net Zero Peak Cluster carbon capture and storage project, with the development entering the Assess Phase of its UK carbon storage licence.
The project would repurpose the depleted North and South Morecambe gas fields in the East Irish Sea for long-term CO₂ storage after gas production ends later this decade. Studies indicate potential storage capacity of around 1 billion tonnes of CO₂, making the site one of the largest proposed offshore carbon stores serving UK industry.
Progress into the Assess Phase follows technical work including a high-resolution 3D seismic survey and subsurface imaging programme across about 500 sq km of the East Irish Sea. The survey work has been used to assess reservoir suitability, storage integrity, and the conditions needed to prepare a future permit application.
The Morecambe Net Zero Peak Cluster project is being developed with Peak Cluster and is intended to transport and store up to 3 million tonnes of CO₂ each year from cement and lime plants in Derbyshire and Staffordshire. Those sectors remain difficult to decarbonise because a substantial share of emissions comes from process chemistry, not only from energy use.
Converting mature gas fields into a carbon store draws on decades of offshore engineering knowledge, but the technical requirements are not a simple reversal of production. Carbon storage requires assurance over reservoir behaviour, injection performance, legacy well integrity, corrosion control, monitoring systems, and long-term containment. The operating duty changes from extracting gas safely to locking injected CO₂ away for decades.
Offshore infrastructure also has to connect with onshore capture systems, compression, transport pipelines, metering, and regulatory monitoring. The resulting network depends on industrial emitters, transport operators, storage developers, regulators, and government policy working to compatible timescales. Cement and lime plants cannot decarbonise through storage alone unless capture equipment and transport infrastructure arrive with the offshore store.
The location gives the project a different role from the east coast carbon capture clusters that have dominated much of the UK discussion. Linking central England’s cement and lime producers with storage in the East Irish Sea could broaden the country’s carbon infrastructure map and create a storage route for industrial regions outside the most developed cluster geography.
The project also sits alongside wider work to reuse established offshore and process engineering capability for lower-carbon infrastructure. Complex offshore process projects, including large floating LNG engineering programmes, continue to depend on integration, safety, uptime, and long operating lives. Carbon storage applies those same engineering disciplines to a different industrial objective, with subsurface risk and monitoring at the centre of the asset.
Carbon capture remains a contested part of industrial decarbonisation, but cement and lime leave few credible alternatives at scale. Electrification can reduce some energy-related emissions, and alternative materials can reduce demand in specific markets, yet the chemistry of calcination still releases CO₂. Storage projects therefore become part of the infrastructure required to keep essential materials production operating under tighter carbon constraints.
The economic case is tied to that industrial base. Project partners have estimated that Morecambe Net Zero could contribute around £1.8 billion to the UK economy by 2050, support more than 13,000 jobs, and attract further construction and operational investment. Those outcomes will depend on permitting, final investment decisions, industrial customer commitments, policy stability, and the commercial framework for transport and storage.
The next phase will be shaped by detailed engineering rather than headline capacity. Well assessments, reservoir modelling, injection design, platform and pipeline decisions, monitoring plans, and safety cases will determine whether the scheme can move from a licensed concept into bankable infrastructure. Carbon storage licences create a route forward, but the engineering still has to demonstrate that captured emissions can be transported and stored with confidence.
Morecambe’s progress gives the UK another route for connecting hard-to-abate manufacturing with offshore storage. If the project advances through assessment and permitting, it could turn depleted gas infrastructure into a long-life industrial decarbonisation asset serving sectors that cannot remove emissions through efficiency measures alone.
