SHINE (Non-Electric Boiler)
Power outages are a regular occurrence in Great Britian with average annual customer minutes lost in Great Britain range between 31.57 minutes 51.4 minutes depending on the Distribution Network Operator License Area (Statista, 2021). This is of course not evenly distributed with outages varying from a few minutes up to more than a week in more extreme circumstances. Similarly, single outages can affect a single property or several thousand properties depending on the cause. This project will aim to develop a low-cost, user-friendly solution, whereby customers in vulnerable situations will still be able to use their gas heated boiler, as well as LPG and oil heated boilers, in the event of a power outage.

Scaling Hydrogen with Nuclear Energy (SHyNE)
Significant efforts are required to support the transition of our energy systems moving away from carbon-intensive fuels such as coal, diesel, petrol and gas, towards cleaner sources of power generation such as wind, solar, nuclear and hydrogen. There is a potential for hydrogen to play a hugely significant role in our energy system, the extent of which will be driven by a range of factors, including the ability to transport it to where it is needed. There have been recent positive decisions for hydrogen’s potential uses in blending, transportation, domestic heating and industry. To produce sufficient hydrogen to meet this potential need, it will be important to increase and diversify hydrogen production methods.
As nuclear is a reliable and consistent source of clean energy that is unaffected by external factors such as the weather, Northern Gas Networks and Wales and West Utilities would like to investigate the possible use of nuclear power as a method of delivering the future increased demand in hydrogen production. This project will explore the opportunity for hydrogen production from nuclear to support a net zero transition across the gas network.
Benefits of nuclear-enabled hydrogen (NEH) in the context of gas distribution networks (GDNs) will be explored, building on the established benefits of nuclear energy production.
The overall project outcome is that NGN, WWU, and other stakeholders are sufficiently informed to determine whether further investment and integration of nuclear-enabled hydrogen to transition plans are justified, and how a potential first project could take its next step to deployment through securing technology licences, sites, off takers and financing.

Stopple-Live trial (Phase 2)
The Stopple technology is a flow stop tool essential for major projects and emergency works across the LTS and NTS gas network. Its capability was tested in 100% hydrogen within a helinite environment, in line with LTS Futures parameters as phase 1. This project focuses on validating flow-stopping technology as an additional deliverable with LTS Futures live hydrogen trial on the Granton to Grangemouth pipeline as a welded tee and hot-tapping operations is already being carried out. The trial will confirm the Stopple train’s effectiveness as a double-block and bleed solution for a 100% hydrogen system which will be available for the UK Gas Network. The findings will provide critical insights into the safe and efficient operation of the hydrogen networks supporting the transition from natural gas to hydrogen.

The Impact of District Heating on Our Network
This project will investigate the potential impacts of district heating on the gas network, whether its viable for the network to support district heating and what repurposing would be required.

The Potential of Biomethane to Accelerate the Decarbonisation of UK HGVs
The following is a proposed outline for a report on the decarbonisation benefits and potential of biomethane in the UK Road Haulage sector.
The report will position biomethane as:
- A complimentary technology to zero tailpipe emission vehicles that offers faster decarbonisation potential due to the near-term infrastructure scalability of the technology and the suitability for long distance and non-fixed route logistics.
- A cost-effective way to reduce Carbon emissions by over 84% over the next 15-20 years whilst zero tailpipe emission technologies are developed, and the supporting infrastructure is deployed.
- An enabler to the transition to zero tailpipe emission vehicles by offering reduced carbon abatement costs that, in turn, can generate funds to invest in zero emissions infrastructure and vehicles.
It will serve as a reference document for discussions with industry stakeholders, governments, and regulators.

Understanding the value of remote detectors
The statistical ‘value’ (i.e. risk reduction and cost) of remote hydrogen detectors has been determined through statistical based projects as part of the hydrogen heating programme (HHP). The cost has been shown to outweigh the risk, however, given hydrogen is not a mature heating solution, the cost can be justified in response to risk appetite from key stakeholders, such as consumers. This risk appetite is assumed. There is currently no analysis (qualitative or quantitative) into consumers attitudes towards the ‘value’ of remote detectors. This project will begin to explore the perception of risk reduction from remote detectors to be used to compliment the statistical based analysis to paint a fuller picture towards the utilisation and crucially, the value, of remote detectors.

Welding Residual Stress Measurements and Analysis for Gas Pipelines
This project concerns the research into welding residual stress values and the effect that they have on the overall pipework repurposing assessment route described in relevant hydrogen standards. Currently, overly conservative values need to be applied for welding residual stresses in any repurposing assessment. This project aims to build evidence on actual and modelled residual stresses seen within the pipelines industries, with a focus on natural gas pipelines. As the welding residual stress is a critical aspect of the fracture mechanics assessment, any improvements which can be gained would have an overall positive impact on the assessment results.

Wireless Methane Odorant Detector
This project aims to improve natural gas leak detection for over 3.5 million people with acute smell disorders e.g. anosmia. Traditional methane sensors require high power, limiting placement. The legally required odorant (80% tert-butyl mercaptan and 20% dimethyl sulphide) will continue as the UK transitions to hydrogen or blends, necessitating re-calibration of detectors.
Our solution is an odorant-based gas detector using a custom ultra-low power electrochemical sensor to measure TBM. These sensors operate for over 10 years on a sealed lithium-ion battery, detecting TBM from 20-30ppb (below our smell threshold) up to 1,500ppb (20% of the Lower Explosion Level), ensuring early warning of gas leaks.
With no natural sources of TBM, false positives are eliminated. The Sensor is ‘hydrogen ready,’ maintaining consistent odorant levels during the transition to hydrogen or blends, accurately notifying of gas leakage without reconfiguration.
