Uniper UK Limited - Connah’s Quay Low Carbon Power Station, Kelsterton Road, Connah’s Quay, Deeside, Flintshire, CH5 4BP
We’ve received an application for an environmental permit from Uniper UK Limited.
New bespoke application for an environmental permit under the Environmental Permitting (England and Wales) Regulations 2016.
Application number: PAN-031638
Regulated facility type: Installation - Section 1.1: Combustion Activities - Part A (1)(a) Burning any fuel in an appliance with a rated thermal input of 50 or more megawatts.
Section 6.10: Carbon Capture and Storage – Part A (1)(a) Capture of carbon dioxide streams from an installation for the purposes of geological storage pursuant to Chapter 3 of Part 1 of the Energy Act 2008 and other EU-derived domestic legislation which transposed Directive 2009/31/EC on the geological storage of carbon dioxide in relation to England and Wales.
Medium Combustion Plant - Schedule 25A – Medium Combustion Plant, and Specified Generators (SG) that are excluded.
Regulated facility location: Connah’s Quay Low Carbon Power Station, Kelsterton Road, Connah’s Quay, Deeside, Flintshire, CH5 4BP.
The application is for a new combined cycle gas turbine (CCGT) power station fired on natural gas. A post-combustion carbon dioxide capture plant (CCP) is also proposed to reduce atmospheric carbon dioxide emissions from the power station. The CCP will use an amine-based solvent to absorb carbon dioxide (CO2) from the exhaust gases. The captured carbon dioxide will be transported off-site for geological storage. A number of emergency diesel generators are included in the application. In the event of a power cut, these generators combust diesel to generate electricity, which allows the plant to safely shut down. The emergency generators are classed as Medium Combustion Plant.
The application contains a description of the proposed installation; the materials, substances and energy it will use and generate; the conditions of its site; the source, nature and quantity of its foreseeable emissions and their potential impact, the proposed techniques for preventing, reducing, and monitoring its emissions and preventing and recovering waste; and an outline of the main alternatives, if any, considered.
You can see the application documents free of charge, from our online public register or you can request a copy of the information from us. This may take time to process and there could be a charge.
