Wales & West Utilities (WWU) has partnered with Costain to conduct a study on green energy alternatives for its industrial and commercial (I&C) customers, with a focus on transitioning to a lower-carbon network through hydrogen blending or conversion. Many I&C customers connected to the natural gas network face challenges in decarbonisation due to high energy demands that electrification alone cannot meet. The study aims to explore the role of hydrogen and blending solutions in the gas network to support the UK's net zero goals. Qualitative and quantitative data will be gathered to assess the market's understanding of hydrogen refuelling plans and customers' preferences for decarbonisation methods like carbon capture or a hydrogen network. Geographical mapping of users will help WWU identify customers needing additional support for a smooth transition to hydrogen blending. WWU's commitment to facilitating sustainable energy transitions is emphasized by the head of net zero and sustainability, Matthew Hindle. Costain's involvement extends to supporting WWU in decarbonisation efforts, including integrating hydrogen refuelling stations into the existing gas network. Laura Hughes, energy sector director at Costain, highlights their expertise in providing insights for viable fuel switching plans to drive sustainable energy practices.
