Carbon Capture and Utilisation Plant, Winnington

We provided environmental permitting advice to Tata Chemicals Europe for the largest carbon capture and utilisation plant in the UK.

The plant will capture approximately 40,000 tonnes of CO2 per year which will be used to manufacture sodium bicarbonate at TCE’s nearby facility. We provided permitting advice, supported pre-application and post-submission discussions with the EA, and provided support for full permit variation application and post-application services, including air dispersion modelling and odour assessment. We also supported the application to vary the water abstraction licence to incorporate the additional volume of cooling water required for the CCU process.

The CCU plant will use an amine solution to capture CO2 from the exhaust gases from the gas-fired Combined Heat and Power (CHP) plant on the same site, which supplies heat and power to TCE’s operations in the area and to other local industries. The plant will purify and liquefy the captured CO2, after which it will be stored before being used to manufacture sodium bicarbonate at TCE’s local facility.

There was a lack of existing data and guidance available in the UK for this relatively new technology, which hasn’t been operated on this scale yet in the UK. We worked together with TCE, the technology provider and the EA throughout the process to agree the approach and to gather the necessary data to support the proposals for the facility in the absence of a defined regulatory position. The key permitting challenges posed by this project were:

  1. The lack of defined best available techniques (BAT) for carbon capture technology
  2. The absence of defined emission limit values (ELVs) for key emissions
  3. The absence of environmental assessment levels (EALs) for key emissions
  4. The lack of defined monitoring regime for key emissions



To address the lack of defined best available techniques (BAT) and emission limit values (ELV), we conducted a BAT assessment early on. This set out supporting information for the proposed ELVs and for BAT for reducing monoethanolamine (MEA), a pollutant emitted as a result of the solvent used. We referred to European guidance, pilot plant results and information from the technology provider. This assessment was discussed with the EA at the pre-application stage and the submission was accepted as BAT during determination.


There were no environmental assessment levels (EAL) for the key pollutants MEA and nitrosamines. For MEA, the EAL used was derived from workplace occupational exposure limits. For nitrosamines, an EAL from the Norwegian Institute of Public Health was used.

We worked with the determining officer to have early sight of the EA’s monitoring expectations. After reviewing the feasibility of the proposed suite with analytical laboratories, we agreed a revised monitoring suite that included only parameters where approved monitoring methods were available to ensure EA monitoring expectations could be delivered.
