The Environment Agency has granted Drax Power Limited a variation to its environmental permit for Drax Power Station near Selby, allowing the permit framework to cover a proposed post-combustion carbon capture plant. The press release announcing the decision was published on 14 August 2026, while the underlying permit and decision document were issued on 5 August 2026. The captured carbon dioxide is intended for transport and permanent storage under the North Sea. (gov.uk) In regulatory terms, this is not a ruling on every wider argument around Drax or biomass. It is a determination under the Environmental Permitting (England and Wales) Regulations 2016 and the Industrial Emissions Directive framework, focused on whether the operator has shown it can comply with permit conditions and operate without causing unacceptable harm to human health, wildlife or the environment.

The Environment Agency's position is narrow but important. It may refuse a permit or variation only where legal requirements are not met, including where impacts on the environment or human health would be unacceptable. In its decision document, the Agency says it took account of the application, further information and consultation evidence before concluding that the varied permit would provide a high level of protection for the environment and human health. (gov.uk) That explains why the official language is framed around obligation rather than discretion. The Agency's public statement says Drax demonstrated that it had met, and would continue to meet, the mandatory conditions in the permit, and Ian Foster said the consultation evidence had been reviewed and no basis had been found to conclude the operator could not comply. (gov.uk)
The chronology also helps explain the length of the process. The decision document shows that the application was handled as a staged submission, with material lodged in August 2022 and April 2023 before the application was treated as duly made on 18 May 2023. The first public consultation then ran from 26 May 2023 to 29 June 2023, with notices on the Environment Agency website and in the Yorkshire Post. (assets.publishing.service.gov.uk) The process extended because the Agency concluded that more information was needed. A revised air impact assessment was advertised for consultation from 4 February 2025 to 4 March 2025, a separate CO2 venting assessment was requested and reviewed later in 2025, and the draft decision itself was opened for comment from 27 May 2026 to 24 June 2026. In other words, the permit variation that has now been granted is the end point of a three-year determination rather than a single summer decision. (assets.publishing.service.gov.uk)
The decision document shows that consultation was not treated as a formality. Statutory and non-statutory consultees included the UK Health Security Agency, the Health and Safety Executive, North Yorkshire Council, Yorkshire Wildlife Trust and the Food Standards Agency. The Agency recorded 10 responses from members of the public and community organisations on the original application, and five more responses from community organisations and members of the public at draft decision stage. (assets.publishing.service.gov.uk) Those responses fed into further technical work. The decision record refers to extra assessment of air emissions, operating scenarios, solvent-related by-products such as nitrosamines and nitramines, and the risks associated with CO2 venting. At the same time, the Agency drew a clear boundary around its remit, stating that some objections, including broader concerns about the sustainability of wood as a fuel, sat outside its powers under the permitting regulations and could not determine this application. (assets.publishing.service.gov.uk)
The permit variation itself is broader than a simple approval for one capture unit. According to the decision document, it covers the carbon capture activity, solvent treatment, CO2 compression and storage, hydrogen production to condition the captured CO2, changes to effluent treatment, modifications to the flue gas layout for units 5 and 6, and removal of the Ouse Renewable Energy Plant from the permit. That is a reminder that carbon capture permitting often requires a wider rewrite of site controls rather than a single additional line in an existing permit. (assets.publishing.service.gov.uk) The Agency has also built in further checkpoints before operation can begin. Before commissioning, Drax must submit finalised information on the CO2 compression system, a refreshed CO2 venting assessment based on the final plant design, a vent management plan, monitoring details and a waste management plan for wastes arising from the capture process. The permit therefore authorises the variation in principle, but it still requires further approval of operational detail before the plant can move into use. (assets.publishing.service.gov.uk)
That structure reflects the fact that post-combustion carbon capture is still treated as an emerging technique. The decision document says the Environment Agency assessed the proposals against its published emerging techniques guidance for post-combustion carbon dioxide capture and for hydrogen production by electrolysis, while also applying the wider requirement for a high level of environmental and human health protection. (assets.publishing.service.gov.uk) The operating controls are correspondingly tighter. The permit requires monitoring of nitrosamine emissions, and the Agency has added an improvement condition requiring a revised air emissions risk assessment after 12 months of monitoring data to test whether actual concentrations match the modelled case. A separate improvement condition requires Drax to report on carbon capture efficiency after commissioning, with the permit expecting the plant to aim for a 95% capture rate and to propose remedial action where that level is reasonably achievable. (assets.publishing.service.gov.uk)
For local communities, the practical point is that approval does not end oversight. The permit requires notification of incidents, accidents, breakdowns, malfunctions and breaches of emission limits, and the operator must shut down the plant if a breach creates an immediate danger to human health or threatens an immediate significant environmental impact. Annual performance and monitoring reports are to be sent to the Environment Agency and placed on the public register. (assets.publishing.service.gov.uk) For officials following carbon capture policy, the Drax case shows the distinction between permitting law and wider energy strategy. The Agency's own documents say some issues raised in consultation fell outside the scope of the determination, and they also note that there is no separate legal obligation for operators to capture CO2 at all times. The control model in this permit is therefore built around enforceable limits, monitoring, reporting and post-commissioning improvement conditions, rather than around a wider ruling on biomass policy or the overall case for carbon capture.
