Costain, an infrastructure solutions company, has been chosen by Wales & West Utilities to assist industrial and commercial gas users in transitioning to low carbon alternatives such as hydrogen. The study will explore how these customers, many connected to the natural gas network, can shift to a lower carbon network either through hydrogen blending or conversion. The challenge lies in decarbonizing operations with high energy demands not met by electrification alone. Understanding the potential of hydrogen and blending solutions is key to driving the UK towards its net zero goals. The research will gather data on the market's understanding of hydrogen refuelling, customer preferences for decarbonisation methods, and mapping users geographically to identify those needing additional support for a smooth transition. Costain aims to provide valuable insights to Wales & West Utilities to facilitate viable fuel switching plans for their customers. Wales & West Utilities is dedicated to supporting their industrial and commercial customers across Wales and the south west of England in implementing sustainable transition plans, including potential hydrogen use. The collaboration between Costain and WWU extends to exploring the integration of hydrogen refuelling stations into the existing gas network. This comprehensive approach signifies a positive step towards a cleaner energy future, aligning with the UK's decarbonisation mission and net zero targets.
