Ofgem invests £164 million in National Gas to advance critical hydrogen transmission pipelines, enhancing the UK’s push towards a resilient, low-carbon energy system and cementing its position as a leader in hydrogen economy development.
Ofgem, the UK’s energy regulator, has granted £164 million to National Gas to progress to the Front End Engineering Design (FEED) phase for three critical hydrogen transmission pipelines, reinforcing the nation’s strategic shift towards hydrogen as a cornerstone of its decarbonisation agenda. This funding allocation breaks down into £67 million for the St Fergus-Teesside route, £40 million for the North West pipeline, and £57 million for the East Coast segment, each slated to collectively form over half of the envisaged 1,500-mile UK hydrogen backbone.
The initiative, known as Project Union, is a flagship endeavour by National Gas Transmission (NGT) to repurpose and upgrade elements of the existing National Transmission System to accommodate 100% hydrogen transport. This transition aligns with broader industrial and governmental ambitions to establish a resilient, low-carbon energy infrastructure supporting decarbonisation across key industrial clusters. The early phase will prioritise the East Coast, linking vital hydrogen production clusters in Humber and Teesside, before expanding throughout the UK.
Engineering consultancy WSP has been appointed as the likely lead for the FEED phase, serving as design integrator since July 2025. National Gas Chief Commercial Officer Ian Radley underscored the significance of the approval, stating, “This is a hugely significant moment for Britain’s hydrogen journey. With Ofgem’s support, we’re moving from discussion to delivery – taking significant strides towards building Britain’s core hydrogen network.”
According to National Gas’s project proposal submitted in 2024, Project Union has the potential to facilitate up to 11.6GW of hydrogen production capacity and meet industrial and power sector demand of approximately 28.3TWh annually. The pipeline network aims to connect low-carbon hydrogen supply with demand clusters including sectors like ceramics, chemicals, and cement, thereby playing a pivotal role in the industrial decarbonisation drive.
This funding aligns with Ofgem’s broader energy infrastructure investment strategy. In July 2025, Ofgem provisionally approved an initial £24 billion plan to upgrade Britain’s electricity supergrid and maintain critical gas networks. Over £15 billion of this investment is dedicated to modernising gas transmission and distribution infrastructure, enhancing the UK’s energy security while reducing reliance on volatile global gas markets.
Project Union also complements the East Coast Hydrogen programme, which received £96 million in June 2025 aimed at establishing a reliable hydrogen network spanning the Northeast, Humber, Yorkshire, and the East Midlands. This initiative focuses on repurposing existing pipelines and constructing new infrastructure to deliver low-carbon hydrogen to industries pivotal to the UK economy.
The hydrogen backbone envisioned under Project Union will not only leverage existing gas transmission assets but also introduce new pipeline construction, allowing for scalable growth and strategic integration with a wider European hydrogen network. This interconnected network is designed to support the UK’s ambition for a clean, secure, and resilient energy system to underpin both industrial demand and power generation as part of the country’s net-zero commitments.
Earlier preparatory steps towards the detailed design phase included pre-FEED activities conducted in collaboration with engineering firms Jacobs and ERM, engaged in late 2023 to define route options and feasibility assessments for the hydrogen backbone.
While National Gas expresses confidence in the transition facilitated by Ofgem’s funding, the ambition to retrofit and expand existing gas infrastructure into a dedicated hydrogen transmission system presents logistical and technical challenges. Success will depend on precise engineering execution, regulatory continuity, and industrial collaboration.
As the UK moves decisively to integrate hydrogen alongside electrification within its energy mix, Project Union stands as a critical infrastructure project that could transform the industrial landscape and help position Britain as a leader in hydrogen economy development. The approved funding marks a substantive step from concept to delivery, symbolising a pivotal moment in the UK’s industrial decarbonisation pathway.
