Projects
Non-data centres large demand mapping
New high energy demand sites in the UK can face grid connection delays of over 10 years due to overloaded electricity networks which are struggling to keep up with growing demand. Gas networks could help bridge this gap by supplying gas-to-power solutions to support critical areas sooner. Knowing where and when demand will arise will help gas networks target investment support electricity networks in offering alternatives and allow energy users faster access to power. In this way gas networks can play a key role in getting large energy users the power they need when they need it.
Flexible Gas Transition Plant – Phase 1 Feasibility Study
Analysis of the distribution networks undertaken in the H2 Caledonia and H2 Connect projects has identified sectorisation isolation as the optimal approach for conversion. Sectorisation isolation allows for a sector-by-sector approach ensuring the gradual conversion of existing Natural Gas connections over to hydrogen or managing the disconnection process should customers opt for alternative heating solutions. This project will aim to develop an understanding of the technical and financial feasibility of a Flexible Gas Transition Plant (FGTP) through primary project outputs such as: outline of design options development of a list of transition use cases a cost benefit analysis (CBA) for each transition scenario and a roadmap for future phases including prototype design and trials.
Forecaster for Embedded Generation (FEmGE)
Gas networks supply embedded power stations that support the electricity network. These embedded generators can fire up without any warning to GDNs and is causing significant challenges to gas networks.
GDNs are required to submit hourly gas demand nominations to National Gas for each offtake point within specified time deadlines.
Embedded generators are small. They are not included in the UNC’s requirements to notify their GDN of intended offtake activity due to their size being below the threshold for NExAs (network exit agreements). Despite this GDNs must include the demand from these embedded generators in their nominations to ensure there is sufficient gas within their network. This causes numerous challenges for SGN and other GDNs.
GDNs’ current forecasting process does not specifically forecast embedded gas generation and current models do not take inputs from the electricity market. Embedded generators act in a variety of electricity markets yet GDNs don’t have visibility of this demand.
It is anticipated that additional embedded generators will connect in the coming months/years as the demand for electricity increases.The challenge of not having knowledge of embedded generator’s demand and its potential to contribute to a storage shortage has been acknowledged by both EGRIT (Electricity and Gas Resilience Task Group) and NESO (National Energy System Operator). The benefits of creating a notification platform supported by a ML engine are various. Namely to develop an ML-enabled forecasting tool to predict gas demand from embedded generators with increased accuracy as delivery time approaches. In addition to create a notification platform to improve real-time visibility of embedded generator activities within the electricity and gas networks.
This NIA project aims to progress the FEmGE forecasting tool from TRL 1 to TRL 7 delivering a fully functional MVP. NGN will be funding this project to the value of £92333 and SGN to £184666 of the total of £276999.
LPG to Biomethane Conversion
Wales & West Utilities (WWU) is undertaking a major programme of change to support decarbonisation and deliver a Net Zero gas network. This project explores the potential conversion of LPG networks within WWU to biomethane as a pathway to decarbonisation. The initiative is driven by the challenge of replacing LPG in rural off-grid communities where previous alternatives—such as hydrogen blending or full electrification—face significant technical storage and infrastructure constraints.

Understanding Consumer Behaviours for a Just Energy Transition
This project will deliver independent evidence‑based research on consumer behavioural insights relating to domestic heat sources during the energy system transition. It comprises four work packages (WP0–WP4) that build on one another to create tangible outputs for WWU and other Network Licensees: desk research and gap analysis (WP1) SME engagement and sentiment analysis (WP2) consumer research including a 4000‑respondent survey user‑journey mapping and CIVS insights (WP3) and integration of insights through decision trees synthetic population modelling and cost‑benefit analysis (WP4).
Air Ingress in Multi Occupancy Buildings (MOBs)
This project will help to inform UK Gas Distribution Network Operators (GDNOs) and wider industry on the impact of the potential for air ingress into gas-conveying pipework in MOBs. The mechanisms for air ingress into gas-conveying pipework have been shown to be gas agnostic though this project will focus on impacts specific to future hydrogen distribution to MOBs.
PE Service Pipe Disconnection Phase 2
The PE Service Pipe disconnection project is an evolution from the development project in phase 1 this project is a monitored field trial evaluating a new non-excavation method for permanently disconnecting polyethylene (PE) gas service pipes that terminate in external meter boxes. Developed in collaboration with Steve Vick International and UK Gas Transporters the technique uses a foam plug and sealant system deployed through the external emergency control valve to safely isolate and abandon the service pipe as near as reasonably practicable to the main. The aim is to demonstrate compliance with gas safety legislation while reducing the need for highway excavation lowering costs improving safety and minimising disruption. The trial will gather operational safety and performance evidence to support potential wider adoption and HSE acceptance.
MASiP Phase 3 (Qualification Testing & Integrated System Development)
The MASiP Phase 3 is developing a new pipeline system to serve as an alternative to conventional steel pipelines in the transmission network. The material used in this pipeline will render it capable of transporting natural gas biogas and up to 100% hydrogen. Building on Phases 1 and 2 this phase focuses on the technical assessment of tight radius bends tees and damage repair as well as the integration of live monitoring systems in a prototype operational environment.
Comprehensive validation will include connectors coatings repair systems hot-tapping solutions ground movement tolerance durability and design life testing. All testing will be carried out in accordance with IGEM API and ASME standards.
The key deliverable is a validated deployable hydrogen-ready pipeline system that is safe compliant and cost-effective offering potential cost savings of up to 50% compared with steel. The project outcomes will support the UK’s RIIO-GD2 strategy and 2050 net-zero targets by enabling hydrogen-ready infrastructure improving monitoring installation efficiency and long-term reliability while also providing the evidence base required for regulatory policy and industry acceptance of alternative pipeline materials.
Catalysing Biomethane Growth in the UK
This project constitutes a UK-wide strategic assessment of the policy and regulatory frameworks governing biomethane production and grid injection with the objective of identifying how these frameworks can be updated to unlock growth. The review will examine the current policy landscape support mechanisms and regulatory arrangements affecting biomethane development including uncertainties associated with existing schemes and fragmented governance structures.
Unlocking the role of nuclear in low carbon hydrogen and heat
This project constitutes a research study which will explore how nuclear energy can support a whole system energy transition by providing for the energy requirements of low-carbon hydrogen and heat networks within regions where renewable energy potential is relatively low. These are areas where hydrogen demand will need to be met by imports unless hydrogen production methods can be increased and diversified.
Biomethane feedstock mapping and strategic growth planning study
This project constitutes a GB-wide analysis of biomethane feedstock arisings including location determination of quality and composition of each feedstock type and biomethane production potential. Arisings will be quantified to county-level. Mapping software will be used to determine feedstock hotspots and alignment with the grid will be considered. The results of these analyses will be combined to consider how and where sustainable biomethane growth can best be achieved.
Open Maps
This project has enormous potential to benefit all customers in vulnerable situations as it will provide accurate assessment of communities and all interested parties to provide suitable support to the area. This will enable GDN DNO Electricity transmission and Gas transmission partners such as community groups to specifically target areas with relevant support this will allow project partners to accurately provide information which will be bespoke to the specific needs of the area such as Carbon Monoxide awareness Priority Services Register messaging increasing awareness and registrations.
It will allow GDN’s or other service providers to enlist support for VCMA BAU or NIA projects directly addressing the needs of communities rather than adopting a broad-brush approach which has been the traditional approach. This system will present itself as the very foundation for future years projects and investments specifically as we progress through the energy system transition which will help address the very real and ever-changing needs of communities and vulnerable customers groups by putting data at the front and centre of future decision making for GDN’s and partners.
Development of Technical Readiness for Bends and Tees
Hydrogen design codes require fracture mechanics based design and qualification for high stress service. Procurement of a number of Long Lead Items (LLI) is required to construct commission and operate hydrogen networks. A number of these LLIs including induction bends and barred tees remain at a low technical readiness.
This project will carry out fracture toughness testing in a hydrogen environment to increase the technical readiness support the supply chain and achieve operational schedules.
Reducing Gas Emissions During Pipeline Commissioning
Based on previous work ROSEN Engineers believe the quantity of natural gas vented during commissioning operations can safely be reduced by up to 80% through targeted changes to direct purging procedures.
For Gas Distribution Networks’ (GDNs) gas venting remains a necessary part of normal operations for maintenance or safety purposes. Previous research work undertaken by ROSEN(UK) Limited for the EIC with project partners Northern Gas Networks (NGN) and Wales and West Utilities (WWU) identified activities where venting of natural gas to atmosphere occurs (Gas Venting Research Project NIA reference number NIA_NGN_282)
Development of Technical Readiness for Large Diameter Ball Valves
In order to construct commission and operate new hydrogen pipelines and installations safely and as part of modifications to existing assets for repurposing ball valves are required to carry out isolations. Selected ball valves need to have been proven to be suitable for service in large diameter high pressure hydrogen networks.
This project will carry out performance validation testing on a 32” ball valve to confirm suitability to operate in high pressure hydrogen networks.
Repurposing gas pipelines for SAF
This project evaluates the rapidly developing Sustainable Aviation Fuel (SAF) sector and assesses the technical commercial regulatory and safety feasibility of repurposing existing gas pipelines to transport liquid aviation fuels. The uptake of SAF is critical to decarbonising the UK aviation industry and achieving net zero targets. To support the scale-up of SAF production and use the development of reliable affordable and low-carbon infrastructure is essential. Pipelines offer a cost-effective environmentally sustainable and high-capacity transport solution. The study aims to enable scalable SAF infrastructure while providing a productive long-term use for gas assets that are unlikely to be required for refurbishment or alternative repurposing.
Validation of Olfactory Assessment Methodology for 100% Hydrogen Network
To ensure that the users and general public recognise and report hydrogen leaks without further education current guidance states that the smell of hydrogen should be indistinguishable from that of natural gas. It is also expected that the same odorant will be used in hydrogen networks as is currently injected to natural gas and so it is essential to ensure that existing methodologies for olfactory assessment (Rhinology) originally developed for natural gas are safe effective and applicable to 100% hydrogen environments.
MOB Transition Pathways – Regulatory & Strategic Governance
This project is a research and analysis desktop study to provide a clear evidence base for regulatory and strategic governance pathways related to multi-occupancy building (MOB) decarbonisation. By mapping legislation standards and regional constraints SGN will develop the building blocks for a decision-making framework to justify future investment and planning choices across various low-carbon technologies.
MOB Transition Pathways – Future Asset Integrity
The initial Hydrogen in MOBs project established the foundational evidence for hydrogen conversion and this follow-on project will address remaining evidence gaps identified by the CFA finalising the safety and regulatory case for MOB hydrogen conversion and enabling a clear handover of outputs to industry. This work also doubles up as an assessment of options we have today to deliver practical and safe designs introducing a new range of risk mitigation options which could be more cost effective and efficient way of managing MOBs and pipe assets. As a practical assessment of technical requirements for conversion this closes out CFA recommendations through applied testing to solve engineering and safety challenges but also informs current processes.
Key deliverables include validated technical data an updated Quantified Risk Assessment (QRA) for MOBs an updated management procedure and a revised IGEM/G/5 Hydrogen Supplement to be formally handed over to IGEM for review. Together these outputs will close out the regulatory and procedural workstream associated with hydrogen in MOBs research.
The project’s findings will also directly support the development of a decision-making framework to support refurbishment and riser replacement programmes. This will enable the industry to make consistent evidence-based decisions on the most appropriate options for MOBs including where alternatives to hydrogen may be more suitable.
