Numerical Modelling of Flame Acceleration and Transition to Detonation in Hydrogen & Air Mixtures with Concentration Gradient
Sep 2017
Publication
Hydrogen gas explosions in homogeneous reactive mixtures have been widely studied both experimentally and numerically. However in practice combustible mixtures are usually inhomogeneous and subject to both vertical and horizontal concentration gradients. There is still very limited understanding of the hydrogen explosion characteristics in such situations. The present numerical investigation aims to study the effect of mixture concentration gradient on the process of Deflagration to Detonation Transition and the effect of different hydrogen concentration gradient in the obstructed channel of hydrogen/air mixtures. An obstructed channel with 30% blockage ratio (BR=30) and three different average hydrogen concentrations of 20 % 30% and 35% have been considered using a specially developed density-based solver within the OpenFOAM toolbox. A high-resolution grid was built with the using adaptive mesh refinement technique providing 10 grid points in half reaction length. The numerical results are in reasonably good agreement with the experimental observations [1]. These studies show that the concentration gradient has a considerable effect on the accelerated flame tip speed and the location of transition to detonation in the obstructed channel. In all the three cases the first localised explosion occurred near the bottom wall where the shock and flame interacted and the mixture was most lean; and the second localised explosion occurred at the top wall due to the reflection of shock and flame front and later develops to form the leading detonation wave. The increase in the fuel concentration was found to increase the flame acceleration (FA) and having a faster transition to detonation.
Safety Issues of the Liquefaction, Storage and Transportation of Liquid Hydrogen
Sep 2013
Publication
The objectives of the IDEALHY project which receives funding from the European Union’s 7th Framework Programme (FP7/2007-2013) for the Fuel Cells and Hydrogen Joint Technology Initiative under grant agreement No. 278177 are to design a novel process that will significantly increase the efficiency of hydrogen liquefaction and be capable of delivering liquid hydrogen at a rate that is an order of magnitude greater than current plants. The liquid hydrogen could then be delivered to refueling stations in road tankers. As part of the project the safety management of the new large scale process and the transportation of liquid hydrogen by road tanker into urban areas are being considered. Effective safety management requires that the hazards are identified and well understood. This paper describes the scope of the safety work within IDEALHY and presents the output of the work completed so far. Initially a review of available experimental data on the hazards posed by releases of liquid hydrogen was undertaken which identified that generally there is a dearth of data relevant to liquid hydrogen releases. Subsequently HAZIDs have been completed for the new liquefaction process storage of liquid hydrogen and its transportation by road. This included a review of incidents relevant to these activities. The principal causes of the incidents have been analysed. Finally the remaining safety work for the IDEALHY project is outlined.
Calibration of Hydrogen Coriolis Flow Meters Using Nitrogen and Air and Investigation of the Influence of Temperature on Measurement Accuracy
Feb 2021
Publication
The performance of four Coriolis flow meters designed for use in hydrogen refuelling stations was evaluated with air and nitrogen by three members of the MetroHyVe JRP consortium; NEL METAS and CESAME EXADEBIT.<br/>A wide range of conditions were tested overall with gas flow rates ranging from (0.05–2) kg/min and pressures ranging from (20–86) bar. The majority of tests were conducted at nominal pressures of either 20 bar or 40 bar in order to match the density of hydrogen at 350 bar and 20 °C or 700 bar and −40 °C. For the conditions tested pressure did not have a noticeable influence on meter performance.<br/>When the flow meters were operated at ambient temperatures and within the manufacturer's recommended flow rate ranges errors were generally within ±1%. Errors within ±0.5% were achievable for the medium to high flow rates.<br/>The influence of temperature on meter performance was also studied with testing under both stable and transient conditions and temperatures as low as −40 °C.<br/>When the tested flow meters were allowed sufficient time to reach thermal equilibrium with the incoming gas temperature effects were limited. The magnitude and spread of errors increased but errors within ±2% were achievable at moderate to high flow rates. Conversely errors as high as 15% were observed in tests where logging began before temperatures stabilised and there was a large difference in temperature between the flow meter and the incoming gas.<br/>One of the flow meters tested with nitrogen was later installed in a hydrogen refuelling station and tested against the METAS Hydrogen Field Test Standard (HFTS). Under these conditions errors ranged from 0.47% to 0.91%. Testing with nitrogen at the same flow rates yielded errors of −0.61% to −0.82%.
Hydrogen and Decarbonisation of Gas- False Dawn or Silver Bullet?
Mar 2020
Publication
This Insight continues the OIES series considering the future of gas. The clear message from previous papers is that on the (increasingly certain) assumption that governments in major European gas markets remain committed to decarbonisation targets the existing natural gas industry is under threat. It is therefore important to develop a decarbonisation narrative leading to a low- or zero-carbon gas implementation plan.
Previous papers have considered potential pathways for gas to decarbonise specifically considering biogas and biomethane and power-to-gas (electrolysis) . This paper goes on to consider the potential for production transport and use of hydrogen in the decarbonising energy system. Previous papers predominately focused on Europe which has been leading the way in decarbonisation. Hydrogen is now being considered more widely in various countries around the world so this paper reflects that wider geographical coverage.
Since the term ‘hydrogen economy’ was first used in 1970 there have been a number of ‘false dawns’ with bold claims for the speed of transition to hydrogen. This Insight argues that this time for some applications at least there are grounds for optimism about a future role for decarbonised hydrogen but the lesson from history is that bold claims need to be examined carefully and treated with some caution. There are no easy or low-cost solutions to decarbonisation of the energy system and this is certainly the case for possible deployment of low-carbon hydrogen. A key challenge is to demonstrate the technical commercial economic and social acceptability of various possibilities at scale. Hydrogen will certainly play a role in decarbonisation of the energy system although the size of the role may be more limited than envisaged in some more optimistic projections.

HyDeploy Report: Gas Characteristics (Leakage, Dispersion and Flammability)
Sep 2018
Publication
The Health and Safety Laboratory (HSL) has carried out an investigation into the gas characteristics that may influence the leakage dispersion and flammability hazards associated with blended natural gas-hydrogen mixtures containing up to 20 % mol/mol hydrogen. The work was carried out under contract to Cadent & Northern Gas Networks as part of the HyDeploy project which was commissioned to investigate the feasibility of using blended hydrogen-natural gas mixtures in UK mains gas distribution networks.
Under the HyDeploy project a demonstration scheme is being carried out at Keele University in which it is planned to inject up to 20 % mol/mol hydrogen. Keele is Britain’s largest campus university and an ideal test site for a demonstration scheme as its gas distribution network is largely independent of the national gas network but still subject to UK gas industry procedural controls. It is anticipated that a successful demonstration scheme will facilitate the use of blended natural gas-hydrogen mixtures throughout the UK leading to significant reductions in carbon dioxide emissions. The project is being led by Cadent & Northern Gas Networks and also involves ITM Power Progressive Energy Keele University and HSL in consortium.

HyDeploy Report: Quantitative Risk Assessment of the Field Trial of Hydrogen Injection into the Keele University Gas Distribution System
Oct 2018
Publication
A consortium comprising Cadent Northern Gas Networks Keele University Health and Safety Laboratory ITM Power and Progressive Energy is undertaking the research project HyDeploy. The project funded under the UK Network Innovation Competition scheme aims to demonstrate that natural gas containing levels of hydrogen beyond the upper limit set out in Schedule 3 of in the Gas Safety (Management) Regulations (GSMR) can be distributed and utilised safely and efficiently in a section of the UK distribution network. It will conclude with a field trial in which hydrogen will be injected into part of a private gas distribution system owned and operated by Keele University. Dave Lander Consulting Limited and Kiwa Ltd are providing technical support to the HyDeploy project and this report presents the results of Quantified Risk Assessment (QRA) for the proposed field trial. The QRA is intended to support an application by Keele University for exemption from the legal requirement to only convey gas that is compliant with the requirements of Schedule 3 of the GSMR. The QRA is aimed at demonstrating that the field trial will not result in a material increase in risk to persons within Keele University affected by the proposed field trial.<br/>Check the supplements tab for the other documents from this report
Zero-In on NI-Heat Exploring Pathways Towards Heat Decarbonisation in Northern Ireland
Jul 2020
Publication
Northern Ireland has achieved its 2020 targets in the electricity sector ahead of time with 46.8% of its electricity demand supplied by renewable generators. When it comes to heat the progress is less impressive – 68% of domestic heating is provided by oil and only around 2500 customers use low carbon heat generators in their homes. In addition 22% of consumers live in fuel poverty. Fuel poverty support programmes still propose the replacement of old oil boilers with new models or with gas boilers where a connection to the grid is possible.<br/>Failure of the commercial RHI scheme and the knock-on effect of the closure of the domestic RHI scheme caused significant damage to the industry and to the reputation of low carbon heat technologies leaving NI consumers without any explicit supporting mechanisms for low carbon heat supply. Decreases in carbon emissions from the heat sector are mainly achieved through switching from oil to gas heating. Gas infrastructure is under development in NI and promises to reach 60% of customers by 2022.
H21- Consumer and Gas Network Metering Phase 1: A Review of the Worldwide Hydrogen Meter Technologies and Applications
Feb 2018
Publication
There is no inherent property of hydrogen that makes it unsuitable for metering at distribution or transmission pressures. Towns gas containing large percentages of hydrogen was used for many years in the UK and continues to be in use in Hong Kong and Singapore. Many manufacturers sell their ordinary mechanical gas meters as suitable for hydrogen in a laboratory or industrial situation; unfortunately lack of demand has meant that none of these meters seem to have certified under appropriate metering regulations for gaseous hydrogen (e.g. the Measuring Instruments Directive)<br/>Some of the more sophisticated modern inferential meters (e.g. thermal or ultrasonic) currently designed specifically for natural gas (or LPG if suitably calibrated) are likely to unsuitable for repurposing directly to hydrogen but none of the problems appear fundamental or insuperable. The largest potential hurdle probably surrounds the physical size of current meters. A hydrogen appliance will consume about 3.3 more hydrogen than natural gas (on a volumetric basis) and using traditional designs this would have been measured through a meter probably too large to fit within an existing meter box. Unless unsolved such an increase in size would add materially to any hydrogen re-purposing programme.<br/>The meter trade thus need to be challenged to come up with a hydrogen meter that is the same physical size as a natural gas meter on a power rating basis (i.e. in kW). Ultrasonic and thermal mass meters should be included in the necessary Research and Development programme.<br/>A meter test programme is suggested that will provide evidence to meter manufacturers that the metering of hydrogen is not inherently difficult and thus convince them to make the necessary investments and/or approach the GDNO’s for assistance with such a programme.
HyDeploy Report: Keele Information
Jun 2018
Publication
Keele University was chosen as the site for the HyDeploy project as it was seen as the site offered a high degree of control regarding safety functions high availability of operational data and minimal supply chain interfaces given that Keele University is the supplier transporter and distributer of natural gas at the site. The site was offered to the project as a living laboratory in line with the university's ambition to be at the forefront of energy innovation through the Smart Energy Network Demonstrator (SEND). Evidenced within this report is the supporting data that confirms the rationale for selecting Keele University and the necessary data to profile the section of the gas network which hydrogen will be injected into. The gas network at Keele University is segregated via the governor stations which regulate pressure within the network. The section of network which has been chosen for the HyDeploy project is the G3 network which is regulated by the G3 governor.
Hydrogen Gas Quality for Gas Network Injection: State of the Art of Three Hydrogen Production Methods
Jun 2021
Publication
The widescale distribution of hydrogen through gas networks is promoted as a viable and cost-efficient option for optimising its application in heat industry and transport. It is a key step towards achieving decarbonisation targets in the UK. A key consideration before the injection of hydrogen into the UK gas networks is an assessment of the difference in hydrogen contaminants presence from different production methods. This information is essential for gas regulation and for further purification requirements. This study investigates the level of ISO 14687 Grade D contaminants in hydrogen from steam methane reforming proton exchange membrane water electrolysis and alkaline electrolysis. Sampling and analysis of hydrogen were carried out by the National Physical Laboratory following ISO 21087 guidance. The results of analysis indicated the presence of nitrogen in hydrogen from electrolysis and water carbon dioxide and particles in all samples analysed. The contaminants were at levels below or at the threshold limits set by ISO 14687 Grade D. This indicates that the investigated production methods are not a source of contaminants for the eventual utilisation of hydrogen in different applications including fuel cell electric vehicles (FCEV’s). The gas network infrastructure will require a similar analysis to determine the likelihood of contamination to hydrogen gas.
Fuel Cell Industry Review 2019 - The Year of the Gigawatt
Jan 2020
Publication
E4tech’s 6th annual review of the global fuel cell industry is now available here. Using primary data straight from the main players and free to download it quantifies shipments by fuel cell type by application and by region of deployment and summarises industry developments over the year.
2019 saw shipments globally grow significantly to 1.1 GW. Numbers grew slightly to around 70000 units. The growth in capacity came mainly from cars Hyundai with its NEXO and Toyota with its Mirai together accounting for around two-thirds of shipments by capacity. Unit numbers are still dominated by Japan’s ene-Farm cogeneration appliances at around 45000 shipments. Large numbers of trucks and buses are now manufactured and shipped in China though numbers deployed are limited by the availability of refuelling infrastructure. But growth in China is uncertain as policy changes are under discussion.
2020 looks like it will be an even bigger year again dominated by Hyundai and Toyota. The Japanese fuel cell market is expected also to grow partly on the back of the Tokyo ‘Hydrogen Olympics’. Korea is another growth story buoyed by its latest roadmap which aims to shift large swathes of its economy to hydrogen energy by 2040. Elsewhere much of the supply chain development is in heavy duty vehicles and big supply chain players like Cummins Weichai and Michelin are making significant investments.

A Comparative Review of Alternative Fuels for the Maritime Sector: Economic, Technology, and Policy Challenges for Clean Energy Implementation
Oct 2021
Publication
Global maritime transportation is responsible for around 3% of total anthropogenic green‐ house gas emissions and significant proportions of SOx NOx and PM emissions. Considering the predicted growth in shipping volumes to 2050 greenhouse gas emissions from ships must be cut by 75–85% per ton‐mile to meet Paris Agreement goals. This study reviews the potential of a range of alternative fuels for decarbonisation in maritime. A systematic literature review and information synthesis method was applied to evaluate fuel characteristics production pathways utilization technologies energy efficiency lifecycle environmental performance economic viability and cur‐ rent applicable policies. Alternative fuels are essential to decarbonisation in international shipping. However findings suggest there is no single route to deliver the required greenhouse gas emissions reductions. Emissions reductions vary widely depending on the production pathways of the fuel. Alternative fuels utilising a carbon‐intensive production pathway will not provide decarbonisation instead shifting emissions elsewhere in the supply chain. Ultimately a system‐wide perspective to creating an effective policy framework is required in order to promote the adoption of alternative propulsion technologies.
Investing in Hydrogen: Ready, Set, Net Zero
Sep 2020
Publication
Achieving the UK's net zero target by 2050 will be a challenge. Hydrogen can make a substantial contribution but it needs investment and policy support to establish demand increase the scale of deployment and reduce costs. The Ten Point Plan for a Green Industrial Revolution confirms the government’s commitment to drive the growth of low carbon hydrogen in the UK through a range of measures. This includes publishing its hydrogen strategy and setting out revenue mechanisms to attract private investment as well as allocating further support for hydrogen production and hydrogen applications in heating.
We have created a bespoke model to help understand the cost of hydrogen in the UK across the value chain under different pathways. Our analysis highlights areas for cost reduction and identifies factors that could make hydrogen more attractive to investors.

Hydrogen Production by Fluidized Bed Reactors: A Quantitative Perspective Using the Supervised Machine Learning Approach
Jul 2021
Publication
The current hydrogen generation technologies especially biomass gasification using fluidized bed reactors (FBRs) were rigorously reviewed. There are involute operational parameters in a fluidized bed gasifier that determine the anticipated outcomes for hydrogen production purposes. However limited reviews are present that link these parametric conditions with the corresponding performances based on experimental data collection. Using the constructed artificial neural networks (ANNs) as the supervised machine learning algorithm for data training the operational parameters from 52 literature reports were utilized to perform both the qualitative and quantitative assessments of the performance such as the hydrogen yield (HY) hydrogen content (HC) and carbon conversion efficiency (CCE). Seven types of operational parameters including the steam-to-biomass ratio (SBR) equivalent ratio (ER) temperature particle size of the feedstock residence time lower heating value (LHV) and carbon content (CC) were closely investigated. Six binary parameters have been identified to be statistically significant to the performance parameters (hydrogen yield (HY)) hydrogen content (HC) and carbon conversion efficiency (CCE) by analysis of variance (ANOVA). The optimal operational conditions derived from the machine leaning were recommended according to the needs of the outcomes. This review may provide helpful insights for researchers to comprehensively consider the operational conditions in order to achieve high hydrogen production using fluidized bed reactors during biomass gasification.
HyDeploy2: Materials Summary and Interpretation
May 2021
Publication
During the exemption application process the original report was evaluated as part of a regulatory review and responses to questions submitted for further consideration. These have been addressed in this revised version (revision 1) in the form of an addendum. The addendum includes the question raised its number and the response to it. The area of the main body of the report to which each question and response refers is indicated by square brackets and the addendum number e.g. [A1].<br/>Through analysis of the literature and results of the practical testing the susceptibility of materials present in the Winlaton trial site to hydrogen degradation has been assessed with consideration of the Winlaton operating conditions (up to 20% H2 at total blend pressures of 20 mbar – 2 bar). The aim of this report has been to determine whether there are any components which have been identified at the Winlaton trial site which could have a significantly increased risk of failure due to their exposure to hydrogen during the one year trial. Where possible direct supporting data has been used to make assessments on the likelihood of failure; in other cases the assessment was aided by collaborative expert opinion in the fields of mechanical engineering materials science and the domestic gas industry.<br/>Click on the supplements tab to view the other documents from this report
HyDeploy2: Summary of Procedures for the Trial Network
Jun 2021
Publication
The assessment of appropriate operational procedures to govern the injection of a hydrogen/natural gas blend into Northern Gas Networks’ (NGN) Winlaton gas distribution network was a key requirement of the HyDeploy2 project. To perform this assessment the review was broken down into two areas procedures upstream of the emergency control valve (owned by NGN) and procedures downstream of the Emergency Control Valve (procedures which would be performed by Gas Safe registered individuals). Assessment of the upstream procedures was led by NGN (own and carry out all upstream procedures on NGN’s gas network) and assessment of the downstream procedures was led by Blue Flame Associates (an industry expert on downstream gas procedures).<br/>Methodologies were adopted to be able to highlight procedures that could potentially be used on the Winlaton trial network during the hydrogen blended gas injection period and if they were impacted by the changing of the gas within the network from natural gas to hydrogen blended gas. This method determined that for downstream gas procedures a total of 56 gas procedures required expert review resulting in 80 technical questions to be assessed and for the upstream gas procedures a total of 80 gas procedures required expert review resulting in 266 technical questions to be assessed.<br/>The operational procedures assessment has led to a determination as to whether a change is or is not required for relevant operational procedures where a basis of concern existed with respect to the injection of hydrogen blended gas. Any requirements to modify an existing procedure has been given in this report referencing the source as to where the detailed analysis for the change/no change recommendation has been given.<br/>The assessment took into account the associated experimental and research carried out as part of the HyDeploy and HyDeploy2 projects such as the assessment of gas characteristics materials impact appliance survey of assets on the Winlaton network and impact of hydrogen blended gas on gas detection equipment references to these studies have been given accordingly to associated impacted operational procedures.<br/>The conclusion of the assessment is that for upstream gas procedures there are some operational procedures that are unchanged some that require an increase in the frequency as to how often they are performed and some procedures which require a technical modification. For downstream domestic gas procedures all procedures applicable to a domestic gas installation were deemed to not be detrimentally affected by the introduction of a 20 mol% hydrogen blend.<br/>For upstream gas procedures an appropriate training package will be built off the back of the results presented in this report and disseminated accordingly to all relevant Operatives that will be responsible for the safety operation and maintenance of the Winlaton network during the hydrogen blend injection period. For downstream gas procedures the Gas Safe community have been fully engaged and informed about the trial.<br/>Click on the supplements tab to view the other documents from this report

North East Network & Industrial Cluster Development – Summary Report A Consolidated Summary Report by SGN & Wood
Nov 2021
Publication
In response to the global climate emergency governments across the world are aiming to lower greenhouse gas emissions to slow the damaging effects of climate change.<br/>The Scottish Government has set a target of net zero emissions by 2045. Already a global leader in renewable energy and low-carbon technology deployment Scotland’s energy landscape is set to undergo more change as it moves toward becoming carbon-neutral. Key to that change will be the transition from natural gas to zero-carbon gases like hydrogen and biomethane.<br/>Scotland’s north-east and central belt are home to some of its largest industrial carbon emitters. The sector’s reliance on natural gas means that it emits 11.9Mt of CO2 emissions per year says NECCUS: the equivalent of 2.6 million cars or roughly all the cars in Scotland. Most homes and businesses across Scotland also use natural gas for heating.<br/>Our North-East Network and Industrial Cluster project is laying the foundations for the rapid decarbonisation of this high-emitting sector. We’ve published a report outlining the practical steps needed to rapidly decarbonise a significant part of Scotland’s homes and industry. It demonstrates how hydrogen can play a leading role in delivering the Scottish Government’s target of one million homes with low carbon heat by 2030.<br/>The research published with global consulting and engineering advisor Wood sets out a transformational and accelerated pathway to 100% hydrogen for Scotland’s gas networks which you can see on the map below. It also details the feasibility of a CO2 collection network to securely capture transport and store carbon dioxide emissions deep underground.
HyDeploy2: Network Information and Maps
Jun 2021
Publication
Winlaton site was chosen as the site for the HyDeploy 2 North East trial as it was seen as the site that offered a high degree of variability with regards materials on the network size of network and statistical representation of housing. The Winlaton trial network is an estate of the wider Winlaton gas network situated in Blaydon near Gateshead. The Winlaton trial network has been isolated from the wider Winlaton gas network where it was previously supplied from and will be supplied with the blended gas from NGN’s Low Thornley gas depot with the installation of a brand-new pressure regulating district governor.<br/>The data contained within this report outlines the expected seasonal gas demand on the Winlaton trial network and the associated leakage and repair history for the network. No unusual repairs or leakage behaviour has been observed on this network. A DSEAR assessment has been conducted on the governor station ensuring ATEX compliance. The network isolation and reinforcement requirements are also given in this report highlighting the necessary actions to isolate the trial network from the wider Winlaton gas network. The NGN Safety Case outlines the risks associated with the operation of a gas grid and the ALARP mitigations developed to minimise them and what response is necessary in case such risks are realised. The existing safety case will be amended to account for the infrastructural operational and commercial changes associated with the HyDeploy 2 project. The report also contains a detailed register of all the assets on the Winlaton trial network this data set was used to inform the scientific research programme and specifically to allow an assessment to be carried out with regards to the operability of the existing and newly installed assets on the Winlaton trial network with respect to the blended gas.<br/>Click on supplement tab to view the other documents from this report
