Overview
Eston Grange Power Station was a proposed coal-fired power station intended for construction near Eston in the Redcar and Cleveland borough of North Yorkshire, United Kingdom. Also known as the Teesside Low Carbon Project, the facility was designed to serve as a flagship demonstration for pre-combustion carbon capture and storage (CCS) technology. If completed, it would have held the distinction of being the United Kingdom's first power plant to utilize this specific CCS methodology, marking a significant potential shift in the nation's energy infrastructure strategy.
The project was developed by Centrica, which served as the primary operator. The station was planned to have an installed capacity of 850 MW, a scale sufficient to supply electricity to approximately one million people. The technical design relied on standard oil refinery technology to gasify coal, converting it into hydrogen and carbon dioxide. This process was central to the plant's carbon capture objectives, aiming to isolate CO2 for storage while utilizing hydrogen for power generation.
Despite its ambitious technical profile and strategic location in the Teesside region, the Eston Grange Power Station was ultimately cancelled. The cancellation reflects the broader challenges faced by large-scale coal and CCS projects in the UK energy market, including economic viability and evolving policy frameworks. The site remains a notable case study in the development and subsequent withdrawal of major low-carbon energy infrastructure proposals in Great Britain.
Why it matters
Eston Grange Power Station holds significant historical importance in the UK energy sector as the nation's first proposed pre-combustion carbon capture and storage (CCS) facility. Its development represented a critical test case for integrating advanced carbon management technologies into the national grid, aiming to demonstrate the viability of large-scale CCS deployment. The project was intrinsically linked to the broader North CCS Cluster strategy, positioning itself as a foundational element in the regional effort to decarbonize industrial and power generation assets in Northern England. By targeting pre-combustion capture, the station aimed to leverage established oil refinery technologies to gasify coal, separating hydrogen and carbon dioxide before the combustion phase. This technical approach distinguished it from post-combustion methods, offering a pathway to capture higher percentages of CO2 with potentially lower energy penalties, a crucial factor for the economic competitiveness of CCS projects.
Strategic Role in the North CCS Cluster
The station's location near Eston in Redcar and Cleveland was strategically chosen to align with the North CCS Cluster's infrastructure plans. This cluster aimed to aggregate emissions from multiple sources, including power stations and industrial plants, and transport the captured carbon dioxide via pipeline to offshore storage sites. Eston Grange was envisioned as a key contributor to this network, providing both the captured CO2 and the generated electricity needed to power the region. The project's success was seen as a catalyst for further investments in the cluster, potentially unlocking billions in capital for other CCS initiatives across the North East and North West of England. Its cancellation, therefore, had ripple effects on the timeline and confidence levels of the wider North CCS Cluster strategy, highlighting the financial and technical risks associated with first-of-a-kind CCS projects.
Technological Innovation and Capacity
This scale was intended to prove that CCS could be applied to utility-scale power generation without sacrificing output efficiency. The use of standard oil refinery technology for gasification was a deliberate choice to mitigate technological risk, relying on proven methods rather than experimental processes. This approach aimed to reassure investors and policymakers that the technology was mature enough for commercial deployment. The project's emphasis on pre-combustion capture also highlighted the potential for producing hydrogen as a byproduct, adding flexibility to the energy mix and offering a potential revenue stream beyond electricity generation. These technological and strategic elements combined to make Eston Grange a pivotal, albeit ultimately unrealized, milestone in the UK's journey toward net-zero emissions.
How does pre-combustion CCS work?
The Eston Grange Power Station was designed to utilize integrated gasification combined cycle (IGCC) technology, a process that fundamentally alters how coal is converted into electricity compared to traditional pulverized coal plants. According to the project's technical specifications, the station would use standard oil refinery technology to turn gasified coal into hydrogen and carbon dioxide. This pre-combustion carbon capture and storage (CCS) approach was intended to make the facility the UK's first plant of its kind, offering a distinct method for reducing greenhouse gas emissions during power generation.
Gasification Process
In a conventional coal-fired power station, coal is ground into a fine powder and burned directly in a boiler to produce steam. In contrast, the IGCC process begins with gasification. The coal is not simply burned; it is subjected to high temperatures and pressures in a controlled environment with limited oxygen. This process converts the solid coal into a synthetic gas, or syngas, which is primarily composed of hydrogen and carbon monoxide. The use of standard oil refinery technology for this stage suggests a reliance on established industrial methods for handling and processing hydrocarbons, ensuring that the gasification unit operates with a level of technical maturity seen in broader energy sectors.
Hydrogen Separation and Carbon Capture
Once the coal is gasified into syngas, the next critical step in the pre-combustion CCS cycle is the separation of hydrogen from carbon dioxide. The syngas undergoes a water-gas shift reaction, where carbon monoxide reacts with steam to produce additional hydrogen and carbon dioxide. This mixture is then processed to separate the two gases. The hydrogen, being the primary fuel, is routed to a gas turbine to generate electricity, while the carbon dioxide is captured before the fuel is burned. This is the defining characteristic of pre-combustion CCS: the carbon dioxide is removed from the fuel stream prior to combustion, as opposed to post-combustion methods where CO2 is extracted from the flue gas after the fuel has been burned.
Combined Cycle Generation
The separated hydrogen is then used as fuel in a gas turbine. As the hydrogen burns, it produces high-temperature exhaust gases that spin the turbine to generate electricity. The exhaust heat is then captured to produce steam, which drives a second steam turbine, creating a "combined cycle" effect that enhances overall thermal efficiency. The captured carbon dioxide, now in a relatively pure and pressurized state, is then compressed and prepared for storage, typically in underground geological formations. This integrated approach allows for a more efficient capture process compared to traditional methods, as the carbon dioxide is concentrated before the combustion step, reducing the energy penalty associated with carbon capture.
What was the infrastructure plan?
The infrastructure plan for the Eston Grange Power Station centered on a pre-combustion carbon capture and storage (CCS) configuration. The station was designed to utilize standard oil refinery technology to gasify coal, separating it into hydrogen and carbon dioxide. This process was intended to make it the United Kingdom's first plant of its kind. The operational design required significant ancillary infrastructure to transport the captured carbon dioxide from the power generation site to offshore storage locations.
Pipeline and Storage Infrastructure
A critical component of the project was the construction of a dedicated pipeline to transport captured carbon dioxide. The plan involved a pipeline with a length of 225 km. This infrastructure was necessary to move the carbon dioxide from the power station site near Eston in Redcar and Cleveland to offshore saline formations. These saline formations were identified as the primary storage medium for the sequestered carbon, ensuring long-term stability of the captured emissions. The pipeline infrastructure represented a significant capital investment, linking the terrestrial power generation facility with the North Sea storage sites.
Shared Infrastructure with Lynemouth
The Eston Grange project was not entirely standalone in its infrastructure requirements. It was planned to share certain infrastructure elements with the Lynemouth power station. This shared infrastructure approach was intended to optimize costs and streamline the carbon capture and storage logistics. The collaboration between the two sites allowed for a more efficient use of the pipeline network and storage capacity. The integration with Lynemouth was a key strategic element in the overall CCS strategy for the region.

Development and competition history
Project Proposal and Technology
Eston Grange Power Station was a proposed coal-fired power plant located near Eston in Redcar and Cleveland, Great Britain. The project was developed by Centrica, which positioned the facility as a pioneering infrastructure asset for the UK energy sector. A defining feature of the proposal was its integration of pre-combustion carbon capture and storage (CCS) technology, which would have made it the first plant of its kind in the United Kingdom.
Government Competition and Shortlisting
The development of the Eston Grange project advanced through a structured government-led competition aimed at identifying viable CCS infrastructure. In 2012, Centrica’s proposal was shortlisted as one of the leading candidates for national investment and support. This shortlisting phase was critical in determining which projects would receive the necessary financial backing and regulatory approvals to proceed to the construction stage. The competition highlighted the strategic importance of integrating CCS technology into the UK’s power generation mix, with Eston Grange emerging as a key contender due to its location and technical specifications.
Elimination and Final Cancellation
Despite its early success, the project faced significant hurdles in the subsequent stages of the competition. In 2014, the Eston Grange Power Station was eliminated from the shortlist, marking a turning point in its development trajectory. The elimination reflected broader economic and policy considerations affecting large-scale energy infrastructure projects at the time. The final blow came in 2015, when George Osborne, then Chancellor of the Exchequer, officially cancelled the project. This cancellation ended Centrica’s efforts to build the UK’s first pre-combustion CCS plant, leaving the 850 MW facility as a significant but unrealized component of the nation’s energy infrastructure plans. The operational status of the station remains cancelled.
What happened to the project?
The Eston Grange Power Station project was formally cancelled, ending its status as a proposed coal-fired facility in Redcar and Cleveland. The cancellation was directly linked to the broader outcomes of the UK government’s Carbon Capture and Storage (CCS) competition. This competition was designed to identify and fund the most viable pre-combustion CCS projects in the United Kingdom, with the goal of establishing the UK’s first large-scale CCS plant. Eston Grange had positioned itself as a leading candidate, leveraging its planned use of standard oil refinery technology to gasify coal into hydrogen and carbon dioxide. However, the competitive process ultimately resulted in the selection of other projects, notably the Teesside Low Carbon Project, which secured funding and political support over the Eston Grange proposal.
Impact on the Teesside Low Carbon Project
The cancellation of the Eston Grange project had significant implications for the regional energy landscape, particularly concerning the Teesside Low Carbon Project. The Teesside project, also focused on pre-combustion CCS, emerged as a primary beneficiary of the competition’s outcome. With Eston Grange out of the running, the Teesside project gained greater prominence as the flagship CCS initiative for the North East of England. This shift concentrated investment and policy attention on the Teesside site, influencing local infrastructure planning and industrial strategy. The decision to favor Teesside over Eston Grange reflected strategic considerations regarding regional economic development, existing industrial clusters, and the potential for cluster-based CCS deployment. Consequently, the cancellation of Eston Grange did not merely remove one candidate from the market; it reshaped the trajectory of CCS implementation in the UK, reinforcing Teesside’s role as a key node in the national low-carbon energy infrastructure.
Reasons for Cancellation
While the official reasons for the cancellation of the Eston Grange project were tied to the results of the CCS competition, underlying factors likely included technical, economic, and strategic assessments. The UK government’s evaluation process for the CCS competition considered multiple criteria, including project readiness, cost-effectiveness, and alignment with national climate goals. Eston Grange, despite its innovative use of pre-combustion technology, may have faced challenges in meeting these criteria compared to competing projects. Additionally, the broader context of the UK’s energy transition, including the rise of renewable energy sources and shifting policy priorities, may have influenced the decision. The cancellation of Eston Grange thus reflects a complex interplay of technological feasibility, economic viability, and strategic planning in the UK’s pursuit of carbon capture and storage solutions.
