Net zero and the energy system transition
Hydrogen device trials
In order to support UK ambitions for hydrogen blending and the development of a hydrogen economy National Gas will need to install new gas chromatographs with the capability to measure hydrogen up to 20% in a natural gas blend. At present hydrogen is not measured anywhere on the National Transmission System (NTS) and therefore there are no proven in-use devices and limited experience within the company to allow effective decision making in deploying these assets in the move towards net zero.
In order to make informed decisions ahead of chromatograph fleet upgrade and to allow for a wide selection of reliable device choices when it comes to that upgrade National Gas require the testing of available devices to analyse their performance and thus suitability for NTS installation. This project will employ a trusted testing house to obtain (through loaning) blend-ready chromatographs from suppliers and then to rigorously examine the performance of those devices. These devices could be tested at the testing house’s site or at the instrument vendor’s site.
Hydrogen Ignition Risk from Static and Autoignition Stage 2B – Static Generation experimentation
The key subject of HIRSA stage 2 projects is to understand if using hydrogen in the gas network will result in an increased likelihood of ignition from static discharge generated by particulates in flowing gas. Building on stage 2A stage 2B will provide further experimental testing aimed at determining the absolute difference in electrostatic charge generated identify whether any external factors impact one gas more than the other and to control the factors affecting generation of the charge. The outputs of this work should provide the industry with a better understanding of the potential change in ignition risk when switching from Natural Gas to hydrogen and will also highlight relevant mitigations to manage this risk.
Fairer Warmth Hub
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 schools social healthcare 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.
Enhancement of the anaerobic digestion process for biomethane production
The UK Government recognised that domestic biomethane production can play a significant role in decarbonising energy supplies. However biomethane production plants face technical and operational challenges. Currently the content of biomethane within biogas produced from the anaerobic digestion (AD) process is often only around 50%. This partial conversion results in lower yields for AD operators and an increase in costly gas scrubbing requirements. The increased presence of impurity gases also increases requirement for propanation to increase the calorific value high in both cost and carbon footprint.
This project seeks to address these challenges through the injection of green hydrogen into the AD process in specific quantities and at specific times to achieve greater conversion of carbon dioxide to biomethane within the acetogenesis stage of the AD process thereby increasing the yield whilst reducing the need for gas scrubbing and propanation.
Decentralised Alliance for South West Hydrogen (DASH)
Early cluster projects will not benefit I&C customers that are located away from industrial clusters and are traditionally more distributed in nature. These customers are unlikely to have access to hydrogen infrastructure developed through the primary industrial clusters. This presents the need for an alternative solution.
This project will explore the concept of how a larger number of low-volume hydrogen producers can support I&C customers in the absence of natural ‘clustering’ and high-volume production by using the South West region of WWU’s network as a case study. This will be done by exploring the whole systems concept of a gas network which is driven by distributed green hydrogen production at strategic locations where there is access to both gas and electricity grid infrastructure.
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.
Project GaIN
As the UK attempts to decarbonise residential heat to meet net zero by 2050 electric heat pumps along with heat networks are expected to play a key role. However it is generally accepted that no one technology will be able to meet the needs of all households. If we are to deliver affordable low- carbon heating in the residential sector we shall need as wide a range of technology options as possible to overcome the economic and technical challenges facing every customer.
Project GaIN (Gathering Insights) will explore alternatives to heat pumps and heat networks which can utilise the robust gas network and benefit from its current upgrade programme supporting the aims of DESNZ’s decarbonisation of heat roadmap. The project will discover and assess additional technology options where alternative solutions might be more costly or difficult to deliver; this will include LAEP system benefits as well as localised CAPEX and OPEX costs.
