Carbon capture - locking up CO₂

Find out more about how HyNet will capture, transport and store carbon dioxide from the local region and its industry. Have your say on the technology behind this and our current consultation to build it.


Give us your views on carbon capture - locking up CO₂
HyNet North West is a project that will unlock a low-carbon future for the North West and North Wales, creating and securing thousands of local jobs and setting the region as a world leader in clean energy innovation. 

HyNet intends to produce clean low carbon hydrogen to replace natural gas. We have an aspiration to provide low carbon hydrogen energy for industry and power generation, as well as energy for homes and transport to decarbonise the whole economy in North West England and North Wales.  

In a process known as carbon capture and storage (CSS), this first stage in the HyNet project will help to remove harmful carbon emissions from local industry, safely transport it via an underground CO₂ pipeline and then securely store that carbon in depleted oil and gas reservoirs under the seabed. Carbon capture and storage is a safe and proven technology that stores carbon dioxide and prevents it from being released into the atmosphere, where it is a major contributor to climate change. Watch our short explainer animation on this process:




To begin this decarbonisation process, we will be capturing CO₂ from existing industrial premises in the Ince and Stanlow area, as well as CO₂ that is produced from the new low-carbon hydrogen production plant at Stanlow. The CO₂ will be transported safely by pipeline to the depleted gas reservoirs in Liverpool Bay. The CO₂ pipeline will comprise of two parts: the construction of a new underground pipeline, which then connects with an existing natural gas pipeline that will be repurposed so that it can transport CO₂.

The new CO₂ pipeline will transport CO₂ produced and captured from existing industrial premises in the Ince and Stanlow area. It will also transport CO₂ from a new low-carbon hydrogen production plant at Stanlow. From here it will run south west through Cheshire and into Flintshire, connecting into the existing repurposed pipeline at a location near Flint. 

The existing onshore pipeline that will be repurposed runs from a location near the existing Connah’s Quay Power Station, and travels west through Flintshire to the existing Point of Ayr Gas Terminal in Talacre. The pipeline then runs under water from the shoreline until it connects to the depleted gas reservoir where the CO₂ will be injected.

As well as the environmental benefits of carbon capture and storage, there will also be new and extensive opportunities for local people. Tapping into the area’s industrial experience and scientific expertise will create a hotspot for innovation and growth. HyNet North West will create opportunities for local people to develop new skillsets and work in exciting, world-leading new sectors. 

By 2030 the amount of carbon captured every year will be the equivalent of us taking four million cars off the road every year.

The carbon pipeline is an essential part of the HyNet North West project, and its support to create a net zero future for the region, and we need your help to make sure we deliver a project that best reflects the needs of local people, businesses and communities. 

While we’ve chosen the broad location of the new pipeline that we want to build, we want to hear your thoughts on its exact route. Through a thorough selection process, we have carefully selected two potential route options, and there are different benefits for each one. You can read more about how we arrived at the two routes we are consulting on in our consultation brochure, and we would like to hear your feedback on these options during this consultation.

We want to start an ongoing conversation about this exciting project for the North West and North Wales. It will bring the region into a true clean, green industrial age, and we want to involve local people, businesses, and communities every step of the way.

We have started to develop our plans for one of the first elements of HyNet North West: the pipeline which will take CO₂ emissions from existing industries to be stored in existing depleted gas reservoirs at Liverpool Bay. As part of our consultation, we have set out our plans for this pipeline, which consists of two key elements:

  • The repurposing of an existing oil pipeline that runs from Flint to Point of Ayr and out under Liverpool Bay so that it can carry CO₂.
  • The construction of a new pipeline to connect the existing pipeline at Flint to industries in Stanlow and Ince.

To what extent do you support or oppose the development of a pipeline to transport CO2 from industries in Stanlow and Ince to underneath Liverpool Bay so that HyNet can safely remove carbon from our industry, homes and transport?

Neither support nor oppose
