Future Energy Networks

As the owner of the National Transmission System (NTS), National Gas is committed to responsibly managing our redundant assets in a manner that contributes to a sustainable, lower-carbon future by decommissioning them responsibly, refurbishing for re-use where viable, and/or or changing their purpose where possible. This discovery project will identify decommissioned elements of redundant pipework on the transmission system which are unlikely to be used for refurbishment or part of any wider repurposing of the core network, and explore the potential of repurposing these for alternative uses including the storage and/or transmission of electrical energy, heat, fuels, water and data.

Wales & West Utilities has developed a Regional Decarbonisation Pathway to provide an overarching strategic plan for the network in Wales and the South West of England. To deliver that pathway, more detailed assessment and planning is required to facilitate the progression of opportunities in particular areas.

In 2023, WWU supported Cadent as the lead partner in the development and delivery of a Functional Blending Specification (FBS) which has progressed the technical understanding of how blending equipment can be practically applied within the context of existing gas network assets (https://smarter.energynetworks.org/projects/NIA_CAD0079/). In 2023, UK Government affirmed their support for network blending whilst networks have continued to develop evidence in support of blending since (Hydrogen blending in GB distribution networks: strategic decision - GOV.UK (www.gov.uk)).

Following completion of Phase 2 of the H21 Hydrogen Ready Components project, this project will look to extend the methodology developed under this project to encompass the assessment of assets operating above 7 barg. The assessment tool will be incorporated into the LTS Futures blueprint methodology for repurposing existing Natural Gas transmission assets to hydrogen. The scope will include transmission assets above 7 barg and up to the maximum transmission pressure of 94 barg and will focus on the conversion to 100% hydrogen. Assets in scope will cover both above and below ground assets, and include bends, valves, regulators, slam shuts, relief valves, and pig traps. Assets excluded include pipelines, compressors and cast iron components.

Augmented Reality (AR) technology will be used at Futures Close to convey and inform various audiences including vulnerable consumers about various property archetypes, their construction, heat loss, and the type of retrofit solutions (heating systems, controls, fabric improvements) available to improve the level of domestic energy efficiency. AR will be used to inform, educate and engage audiences on-site at Futures Close as well as off-site at conferences and meetings avoiding the need to facilitate multiple visits on site. Live data feeds will also be visualised, illustrating room-by-room temperature, humidity as well as other metrics providing an engaging, interactive and informative asset for Futures Close.

As the UK transitions to a low-carbon energy future, gas networks must consider how strategic utilisation of existing assets can be realised. GDNs must also consider adjacent markets such as CCUS and its role in the supply chain now and in the future. The project will take a pragmatic approach to provide SGN with an assessment of the role of the gas network in the growing UK CCUS market

Decarbonisation of UK transport, and the related Zero Emission Vehicle (ZEV) mandate requires companies to transition their commercial vehicle fleets to Battery Electric Vehicles (BEV) or alternative new emerging technologies (e.g. FCEC). As an operational utility network with responsibility for public safety WWU’s fleet undergoes a more challenging and varied range of duty cycles than most commercial fleets, includes vehicles that are required to provide on-site power, and must be capable of meeting WWU’s statutory duty to respond quickly to Public Reported Escapes.

Within this challenging operational context, WWU must deliver a fleet transition at the lowest feasible cost to assure value for money for our customers. This is further complicated by the need to plan the fleet transition while the associated technological and policy landscape continues to evolve in parallel. Although the learnings generated from the project will be specific to WWU’s fleet as a case study, they will be applicable to any networks with an operational fleet.

To assure a cost-effective transition and derisk future operations, WWU require a Total Cost of Operation (TCO) model. This will be specifically targeted at our particular operational context, capable of assessing the costs and capabilities of a range of ZEV options, and crucially must be easy for staff to adopt for internal use and update in the future as new data and/or technologies become available.

The purpose of this project is to provide WWU with a TCO model that addresses our specific operational requirements, ensuring that plans and investment decisions will be grounded in real-world technology assessments and our operational fleet data.

This project constitutes a research study investigating the opportunities for gas network infrastructure to support storage and balancing in a decentralised UK energy system. The research will consider how a decentralised system might look in the UK from now until 2030, and onto 2050. An evaluation will be made of how other countries are approaching decentralisation, identifying examples the UK could draw on. Consideration will be given to how grid balancing will be achieved across various scenarios of peak demand and particular geographic locations in the UK and what challenges and opportunities this presents to gas networks.

Wales & West Utilities is undertaking a major programme of change to support decarbonisation and deliver a Net Zero gas network. Decarbonisation of the vehicle fleet is an integral component of that programme.

WWU operates a fleet of nearly 1,400 commercial vehicles, the majority of these being vans up to 3.5 tonnes GVW. Our fleet – mostly diesel-fuelled - plays a crucial role in providing a safe and efficient service. In addition to our vehicle fleet, WWU operates ~ 900 items of mobile plant, including mini diggers and a wide range of trailers, many of which are specialised.

WWU vans carry a wide range of power-operated tools and equipment, some of this currently being powered by hydrocarbon fuels, some by electricity and some by compressed air. Approximately a third of our van fleet (~400 units) is equipped with ‘full on-board power’ – a compressor and generator, mounted under the van floor and mechanically driven by the diesel engine and operating as a source of on-site power.

This group of vehicles primarily supports below-ground network repair and replacement activity: it is a significant energy consumer, so to help us understand how we can make an operationally cost-effective transition to zero emissions, it is the on-site energy requirements of the tools and equipment powered by this group that Cenex will evaluate for this project. This evaluation will provide information which can take account of (and feed in to) a range of different scenarios for the fleet in the future, such as changes to the number and type of vans allocated to particular teams and projects.

Develop a flexible and adaptable toolset for the rapid analysis of Local Area Energy Plans (LAEPs). This will convert qualitative statements to quantified metrics and identify key network specific planning parameters.

The Fairer Warmth Hub (FWH) connects stakeholders of the Net Zero Transition through place-based strategies, providing tools and guidance to facilitate local energy plans and enhance collaboration. The FWH integrates digital tools and community engagement to facilitate effective communication and planning among diverse stakeholders, including households, small businesses, and local authorities. FWH is designed to bridge the gap in the energy transition by providing tailored support to these stakeholders, ensuring that the transition is inclusive and just. The FWH integrates three core elements:

• Trained ‘Champions’ – Volunteers or staff, known as Champions, are recruited and trained to support community engagement, helping to build trust and reduce miscommunication in local energy initiatives.
• Digital Tools (Virtual Assets) – Innovative digital tools (App + Website) and resources are used to facilitate energy transition planning and community engagement, particularly assisting Customer In Vulnerable Situation (CIVS) and those who are digitally excluded.
• Community Centres (Non-Virtual Assets) – Physical community hubs serve as accessible locations for hands-on support, providing a space for CIVS and other stakeholders to engage directly in the energy transition.
