Carbon dioxide pipeline
Consultation hub

HyNet’s carbon dioxide pipeline will transport carbon dioxide (CO₂) emissions captured from existing local industry, and the new HyNet hydrogen production plant at Stanlow, to be permanently stored offshore in depleted gas reservoirs under Liverpool Bay.

On this site you will be able to find out more information about our plans, and give us your feedback, during our consultation which runs from 9 February – 22 March 2022.

QUICK VIEWS: give is us your thoughts on HyNet in the quick poll

We have also carried out a consultation on the hydrogen pipeline, another important element of the HyNet project. You can find out more by using this separate website:


Our current consultation

As the new-build CO2 pipeline exceeds 16km in length, it is classed as a Nationally Significant Infrastructure Project (NSIP). This means that we need to apply for a special kind of planning consent known as ‘development consent’ which is granted in the form of a Development Consent Order (‘DCO’).

Since our first consultation on the CO₂ pipeline in the Summer of 2021, we’ve carried out detailed surveys and research to carefully narrow down our plans to one proposed route. We are now seeking your views on this final route before we submit our application to build the project. By having your say, you are helping us to deliver a project that will not only power our drive to net zero, but will also benefit the region for decades to come.

The carbon dioxide pipeline consultation is now closed.
