Killingholme Low Carbon Power

The project

Uniper is bringing forward proposals for the potential development of the Killingholme Low Carbon Power (KLCP) project - a new carbon capture power station in the heart of the UK’s industrial Humber region.

This follows the company’s purchase of land next to Uniper’s existing power station site at Killingholme in December 2024, which comes with planning consent for the development of a new combined cycle gas turbine (CCGT) power station (formerly known as the North Killingholme Power Project).

About the project

What is the Killingholme Low Carbon Power project?

The Killingholme Low Carbon Power (KLCP) project is a proposal to develop and commission the consented CCGT power station, so that it’s capable of responding quickly to increases in demand for electricity, contributing towards the UK’s energy supply security.

Uniper also plans to install carbon capture technology at the power station at the earliest opportunity, to capture at least 95% of the CO₂ emissions produced during the electricity generation process.

The development could connect into nearby CO₂ pipeline transport and storage infrastructure, enabling the captured CO₂ to then be safely transported to permanent offshore storage facilities in repurposed depleted gas fields or large saline aquifers.

The KLCP project would be built on the newly purchased land, and the proposed carbon capture technology would be developed alongside the new CCGT power station, subject to receiving separate planning approval, and determining the CO₂pipeline transport route and the permanent offshore CO₂ storage location, to be developed by a third party.

Project plans

The KLCP site

The Killingholme Low Carbon (KLCP) project is located in North Killingholme approximately 5km north-west of Immingham Docks and on land to the west of C.RO Ports Killingholme Ltd (CPK) Terminal at North Killingholme. To the west of the site is the Hornsea substation and Uniper’s existing Killingholme power station, which has been in operation since 1992.

The two component parts of the KLCP project are the consented CCGT and the proposed carbon capture plant. The installation of the proposed carbon capture plant would be subject to meeting development and consent milestones, including Uniper receiving planning approval for the development of the carbon capture plant and having agreed the exact technical solution needed. In addition to the carbon capture plant, our proposals include two route options for a spur pipeline that could connect to nearby CO₂ pipeline transport and storage infrastructure for the permanent offshore storage of the captured CO₂ (which would be developed by a third party).

Public consultation

Uniper is consulting on its carbon capture plant (CCP) proposals for the KLCP project from 11 November to 9 December 2025, prior to submitting a planning application in early 2026. For more information on our consultation and to view our CCP proposals in more detail, please visit our dedicated consultation website here.

How carbon capture works

Carbon capture and storage (CCS) is a key part of the process to reduce carbon emissions in the production of energy and industrial processes. It involves the removal and capture of carbon dioxide (CO₂) from industrial and power plant emissions, transporting it away to be securely stored underground, often in aquifers or depleted oil and gas fields.

The exhaust gases emitted from the gas turbines would be redirected towards the new proposed carbon capture plant that could be installed alongside the consented CCGT power station. The captured CO₂ would be safely transported by pipeline to the storage site and injected it into rock formations deep under the seabed, thereby permanently removing it from the atmosphere.
