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

Hydrogen Valleys. Insights Into the Emerging Hydrogen Economies Around the World
Jun 2021
Publication
Clean hydrogen is universally considered an important energy vector in the global efforts to limit greenhouse gas emissions to the "well below 2 °C scenario" as agreed by more than 190 states in the 2015 Paris Agreement. Hydrogen Valleys – regional ecosystems that link hydrogen production transportation and various end uses such as mobility or industrial feedstock – are important steps towards enabling the development of a new hydrogen economy.<br/><br/>This report has been issued during the setup of the "Mission Innovation Hydrogen Valley Platform" which was commissioned by the European Union and developed by the Fuel Cells and Hydrogen Joint Undertaking. The global information sharing platform to date already features 30+ global Hydrogen Valleys with a cumulative investment volume of more than EUR 30 billion. The projects provide a first-of-its kind look into the global Hydrogen Valley project landscape its success factors and remaining barriers. This report summarizes the findings and presents identified best practices for successful project development as well as recommendations for policymakers on how to provide a favourable policy environment that paves the way to reach the Hydrogen Valleys' full potential as enablers of the global hydrogen economy.

Historical Analysis of FCH 2 JU Stationary Fuel Cell Projects
May 2021
Publication
As a part of its knowledge management activities the Fuel Cell and Hydrogen Joint Undertaking 2 (FCH 2 JU) has commissioned the Joint Research Centre (JRC) to perform a series of historical analyses by topic area to assess the impact of funded projects and the progression of its current Multi-Annual Work Plan (MAWP; 2014- 2020) towards its objectives. These historical analyses consider all relevant funded projects since the programme’s inception in 2008. This report considers the performance of projects against the overall FCH 2 JU programme targets for stationary Fuel Cells (FCs) using quantitative values of Key Performance Indicators (KPI) for assessment. The purpose of this exercise is to see whether and how the programme has enhanced the state of the art for stationary fuel cells and to identify potential Research & Innovation (R&I) gaps for the future. Therefore the report includes a review of the current State of the Art (SoA) of fuel cell technologies used in the stationary applications sector. The programme has defined KPIs for three different power output ranges and equivalent applications: (i) micro-scale Combined Heat and Power (mCHP) for single family homes and small buildings (0.3 - 5 kW); (ii) mid-sized installations for commercial and larger buildings (5 - 400 kW); (iii) large scale FC installations converting hydrogen and renewable methane into power in various applications (0.4 - 30 MW). Projects addressing stationary applications in these particular power ranges were identified and values for the achieved KPIs extracted from relevant sources of information such as final reports and the TRUST database (Technology Reporting Using Structured Templates). As much of this data is confidential a broad analysis of performance of the programme against its KPIs has been performed without disclosing confidential information. The results of this analysis are summarised within this report. The information obtained from this study will be used to suggest future modifications to the research programme and associated targets.
Energy From Waste and the Circular Economy
Jul 2020
Publication
The Energy Research Accelerator (ERA) and the Birmingham Energy Institute have launched a policy commission to examine the state of play barriers challenges and opportunities for Energy from Waste (EfW) to form part of the regional energy circular economy in the Midlands. This policy commission explores the case for regional investment whilst helping shape the regional local government and industry thinking surrounding critical issues such as fuel poverty and poor air quality.
The Challenge
Tackling climate change is one of the most pressing issues of our time. To follow the path for limiting global warming below 2ᵒC set out in the 2015 Paris agreement requires significant reduction in greenhouse gas emissions. The UK has committed to bring all greenhouse gas emissions to net zero by 2050 requiring action at a local regional and national level to transition to a zero carbon economy.
To decarbonise and decentralise the UK’s energy system we must implement technologies that provide energy supply solutions across the UK.
In the Midlands many industrial sites are unable to access supply of affordable clean and reliable energy to meet their demands.
Energy from Waste (EfW) could offer a solution to the Midlands based industrial sites. EfW sites provide affordable secure energy supply solutions that form part of a developing circular economy. EfW reduces our reliance on landfills and obtains the maximum value from our waste streams. There are a number of merging technologies that could potentially play an important role which treats waste as a resource properly integrated into an energy and transport system and fully respects the potential of linking in the circular economy.
Investment into EfW infrastructure in the region could lead to job creation and economic growth and could help provide inward investment needed to redevelop old industrial sites and retiring power stations. However for EfW to be part of a net-zero energy system (either in transition or long-term) technologies and processes are needed that reduce the current carbon emissions burden.
EfW could play a significant role in the net zero carbon transition in the Midlands supplying heat power and green fuels and solve other problems - the region has some of the highest levels of energy/fuel poverty and poor air quality in the UK. The policy commission will help shape the regional local government and industry thinking surrounding this important topic.
Report Recommendations
Recovery Resource Cluster
The EfW policy commission proposes three major areas where it believes that government investment would be highly beneficial
The National Centre for the Circular Economy would analyse material flows throughout the economy down to regional and local levels and develop deep expertise in recycling and EfW technologies. The CCE would also provide expert guidance and support for local authorities as they develop local or regional strategies and planning frameworks.
The R&D Grand Challenge aims to make big advances in small-scale carbon capture technologies in order to turn 100% of CO2 produced through the process of converting waste to energy into useful products. This is very important for areas such as the Midlands which are remoted from depleted oil and gas reservoirs.

HyMotion- Network Supplied Hydrogen Unlocks Low Carbon Opportunities
Jun 2019
Publication
The Government’s recently published ‘Road to Zero’ strategy sets out objectives to electrify cars and reduce emissions from heavy goods vehicles (HGVs) through policies such as ending the sale of diesel and petrol cars and subsidising electric charging infrastructure. The CCC response to the strategy however stated that the proposed measures do not go far enough. New Government policies combined with action from industry will be required for mobility related carbon reduction targets to be met.<br/>Hydrogen has been identified by the Government and CCC as one potential solution. The CCC report on a possible future hydrogen economy recognises that in particular hydrogen may have an important role to play for long distance journeys and heavy goods transport. This view was echoed further in the recent CCC ‘Net Zero’ report.<br/>Cadent’s HyNet project will produce low carbon hydrogen through reformation of natural gas combined with carbon capture utilisation and storage (CCUS). HyNet has primarily been designed to supply low carbon heat to industry and a blend of hydrogen to Cadent’s existing natural gas network but also provides the opportunity to supply low cost hydrogen for mobility. The HyMotion project has considered the relative merits of such an approach modelled potential demand scenarios and sought to determine technical and commercial solutions to enable deployment.<br/>Hydrogen fuel cell electric vehicles (FCEVs) share powertrain technologies with battery electric vehicles (BEVs) but the roll-out of BEVs is currently ahead of FCEVs. This is largely due to a lack of low cost low carbon bulk hydrogen production and refuelling infrastructure both of which HyNet seeks to address.

Liverpool-Manchester Hydrogen Cluster: A Low Cost, Deliverable Project
Aug 2017
Publication
Emissions from natural gas combustion and use are the largest source of greenhouse gas (GHG) emissions in the UK. The use of hydrogen in place of natural gas in principle offers a potential route to long term widespread decarbonisation of gas distribution networks as shown by the Leeds City Gate (‘H21’) study.1 The purpose of considering conversion to hydrogen is to deliver widespread carbon abatement across the UK at lower cost than alternative decarbonisation strategies.<br/>The Government is to finalise and publish the long-awaited ‘Clean Growth Plan’ along with an Industrial Strategy White Paper in Autumn 2017. Conversion from natural gas to hydrogen potentially on an incremental basis would likely represent a major opportunity for new industrial growth. This might be through the longer term stability or potential expansion of existing (newly decarbonised) energy intensive industry or through business opportunities and growth created from new technologies developed to facilitate the transition to hydrogen as the UK becomes a global leader and major exporter of equipment and skills. Job creation and the resulting gross value added (GVA) to the economy could therefore be significant in delivery of the goals of the Industrial Strategy Challenge Fund (ISCF).<br/>The core requirement is to supply low carbon hydrogen in bulk matching production to distribution network demand at an affordable cost. The H21 study concluded that to do so reliably hydrogen is best produced by reducing natural gas in steam methane reformers (SMRs) fitted with Carbon Capture and Storage (CCS). The study proposed that the considerable inter-seasonal and daily fluctuations in network demand can be managed by storing hydrogen in underground salt formations. It concluded that the SMRs with associated carbon dioxide (CO2) capture should be located near to where CO2 transport and storage infrastructure was likely to be created and noted that candidate locations for this are Teesside Humberside Grangemouth and the Liverpool-Manchester (L-M) area. Two of these Humberside and the L-M area are within the Cadent Gas Ltd (‘Cadent’) network and are also industrial ‘clusters’ with significant populations.<br/>The work reported here builds upon the approach proposed in the H21 project by focussing on defining ‘low carbon’ hydrogen supply and distribution systems in Humberside and the L-M area at a system scale sufficient to supply a large city.2 Both the Humber and L-M clusters are close to salt deposits which are suitable for both daily and inter-seasonal storage of hydrogen (for initial or expanded projects). Furthermore new large-scale gas Combined Cycle Gas Turbine (CCGT) plants widely assumed as likely anchor projects for CCS infrastructure have been consented in both cluster areas confirming that they are both strong candidates as locations for the first CCS clusters and hence as locations for a hydrogen supply system.

Use of Hydrogen in Off-Grid Locations, a Techno-Economic Assessment
Nov 2018
Publication
Diesel generators are currently used as an off-grid solution for backup power but this causes CO2 and GHG emissions noise emissions and the negative effects of the volatile diesel market influencing operating costs. Green hydrogen production by means of water electrolysis has been proposed as a feasible solution to fill the gaps between demand and production the main handicaps of using exclusively renewable energy in isolated applications. This manuscript presents a business case of an off-grid hydrogen production by electrolysis applied to the electrification of isolated sites. This study is part of the European Ely4off project (n◦ 700359). Under certain techno-economic hypothesis four different system configurations supplied exclusively by photovoltaic are compared to find the optimal Levelized Cost of Electricity (LCoE): photovoltaic-batteries photovoltaic-hydrogen-batteries photovoltaic-diesel generator and diesel generator; the influence of the location and the impact of different consumptions profiles is explored. Several simulations developed through specific modeling software are carried out and discussed. The main finding is that diesel-based systems still allow lower costs than any other solution although hydrogen-based solutions can compete with other technologies under certain conditions.

HyDeploy2 Technical Services Report: Downstream Gas Standards Review
Jan 2021
Publication
The application of appropriate procedures in the downstream gas industry (defined as any works downstream of the emergency control value) is critical in protecting consumers of gas both domestic and commercial. The two primary standard setting bodies for the downstream gas industry are the British Standard Institution (BSI) and the Institution of Gas Engineers and Managers (IGEM). To ensure only competent engineers carry out works on a gas installation all gas businesses or selfemployed persons must become a member of Gas Safe Register as stipulated by the Gas Safety (Installation and Use) Regulations 1998 1 and each gas operative shall be included on the register and hold a valid license card that covers the areas of gas work they undertake. Membership of the Gas Safe Register is contingent upon demonstration of competency the recognised competency assessments are based on the relevant BSI and IGEM standards. Therefore the primary source of a gas operative’s competency to work on natural gas installations are the associated BSI and IGEM natural gas downstream standards.<br/>Investigation was undertaken to understand the potential implications of introducing 20 mol% hydrogen (H2) within natural gas supplies on the ability of gas operatives to competently carry out works. This investigation took the form of identifying all BSI and IGEM standards that could be applied on natural gas installations and reviewing them within the context of the known effects of introducing a 20 mol% H2 blend. Following review a series of technical questions were generated and responded to by the Health and Safety Executive Science Division. The responses provided were then reviewed and if considered necessary challenged to provide further information. The procedural review was led by Blue Flame Associates a body deemed sufficiently competent in downstream standards training certification and investigation. The report was subsequently reviewed by industry and feedback received. The industry comments were reviewed by the Project Team and where considered necessary the report was updated.
HyDeploy Report: Summary of Gas Appliance and Installation Testing
Jun 2018
Publication
The HyDeploy project has undertaken a programme of work to assess the effect of hydrogen addition on the safety and performance of gas appliances and installations. A representative set of eight appliances have been assessed in laboratory experiments with a range of test gases that explored high and low Wobbe Index and hydrogen concentrations up to 28.4 % mol/mol. These tests have demonstrated that the addition of hydrogen does not affect the key hazard areas of CO production light back flame out or the operation of flame failure devices. It was identified that for some designs of gas fire appliances the operation of the oxygen depletion sensors may be affected by the addition of hydrogen. Testing of the gas fires that are present at Keele University that use oxygen depletion sensors have been shown to operate satisfactorily.<br/>A comprehensive onsite survey programme at Keele University has assessed 95% of the installations (126 of 133) that will receive the hydrogen blended gas during the HyDeploy trial. Where access to properties was not possible then the information obtained revealed that the appliances were annually checked either through British Gas service contracts or as a result of being rental properties. The onsite testing programme assessed installations for gas tightness and appliance combustion safety and operation with normal line gas G20 reference gas and two hydrogen blended gases. The checks identified a small number instances were remedial work was required to correct poor condition or operation. Only one case was found to be immediately dangerous which was capped off until repair work was undertaken. CO and smoke alarms were fitted in approximately half of properties and alarms were provided as required to the occupants. Gas tightness tests identified leaks in three installations. Where installations are gas tight then analysis has shown that no additional leaks would occur with hydrogen blended gas. There were no issues identified with the combustion performance of those appliances that were operating correctly and results were in line with those obtained in the laboratory testing programme.<br/>The findings of the Appliance and Installation testing program have been used to define the input values into the HyDeploy quantified risk assessment (QRA) where Keele University specific operation is different to GB as a whole or where the findings show the addition of hydrogen will change the risk profile.<br/>Click on supplements to see the other documents from this report
