SLB Capturi Selected For Flexible Power Carbon Capture Project In UK

SLB Capturi has been selected as the carbon capture technology licensor for Uniper’s proposed Connah’s Quay Low Carbon Power project in Deeside, United Kingdom. The engineering process, initiated in December 2024, focuses on integrating solvent-based absorption systems with flexible gas turbine power generation to support industrial decarbonization and grid stabilization.

Technical Challenge and Operational Context
Gas-fired power generation operates under variable load profiles to balance intermittent renewable energy inputs within digital infrastructure and power distribution networks. Implementing carbon capture on these generation facilities requires handling flue gas streams with relatively low carbon dioxide concentrations while adapting to rapid variations in exhaust gas flow rates and temperature.

To address these parameters, the project employs amine-based carbon capture processes designed to maintain absorption efficiency during variable operations without compromising baseline power station performance.

System Architecture and Engineering Responsibilities
The implementation utilizes SLB Capturi’s amine-based process architecture, configured with anti-mist hardware and heat recovery systems. These sub-components are designed to reduce solvent loss in exhaust gas and lower the specific thermal energy required for solvent regeneration.

During the front-end engineering phase, SLB Capturi collaborated with Worley and Siemens Energy to integrate the capture plant with existing gas turbine technologies. Under the proposed operational model, SLB Capturi will handle technology licensing, supply specialized proprietary components, and join the integrated project management team to support detailed engineering, commissioning, and system handover.

Infrastructure Deployment and Process Integration
The project is planned adjacent to Uniper’s existing power station in Deeside. The planned facility targets an electrical generation capacity of up to 1.38 GW across two execution phases. Phase one aims to deliver low-carbon power to the UK national grid.

Flue gas from the gas turbines will pass through the absorption system to isolate carbon dioxide. The separated stream will then be compressed and fed into pipeline infrastructure developed as part of the regional HyNet industrial cluster. The captured gas is routed to offshore depleted gas fields for permanent geological storage.

Projected Performance Parameters
The plant design incorporates solvent formulations tested through commercial pilot operations and existing industrial deployments in cement and waste-to-energy facilities. By optimizing thermal energy integration between the power generation unit and the solvent reboiler, the capture unit achieves high recovery rates from low-concentration flue gas.

If the project proceeds following a final investment decision and development consent approvals, phase one operations are targeted for deployment starting in 2030.
