HyLine Cymru is a ground breaking project will transport a homegrown, low-carbon energy solution by doing what Wales & West Utilities do best - expertly connecting our customers with energy whilst investing wisely to create a sustainable, greener future.
HyLine Cymru is our proposal to build a new 130km hydrogen pipeline across South Wales from Pembroke to Port Talbot. This pipeline will help unlock at least 4.5GW of offshore wind in the Celtic Sea by providing a route to market for clean energy producers, whilst transporting a homegrown low-carbon energy source to our hard-to-decarbonise customers.
As well as offering collaborative value in industry, HyLine Cymru will also help local authorities deliver their Local Area Energy Plan, helping Wales achieve its vision for the future.

We support the commitment to delivering a cleaner, greener, and fairer Wales. This means changing the way we produce and use energy at home, in industry and for travel. One of the largest and most challenging sectors to decarbonise is heavy industry. South Wales has a rich industrial heritage; home to industries like cement, paper, steel, mineral wool, chemicals and food. We need to invest for the future to decarbonise industry whilst protecting communities, jobs and the economy in Wales and beyond.
