What we have been consulting on

This consultation relates to an underground pipeline that will safely transport CO₂ 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. Other elements of HyNet will be consulted upon separately. 

We first consulted on these proposals in Summer 2021 when we presented two possible routes for the newly built CO₂ pipeline, along with alternative options for some elements. We have now selected a preferred route which we believe is the best option and on which we would like your comments. Along parts of the preferred route, we are also asking for your views on several ‘sub-options’.

The carbon dioxide pipeline consultation is now closed
