The Dawn of Hydrogen - Fuel of the Future
Aug 2021
Publication
This is a time of enormous change for the gas industry as the UK and the world at large attempts to meet the challenges of decarbonisation in the face of climate change. Hydrogen is expected to play a vital role in achieving the government’s commitment of eliminating the UK’s contribution to climate change by 2050 with the industry creating up to 8000 jobs by 2030 and potentially unlocking up to 100000 jobs by the middle of the century. But despite the UK government’s huge ambitions hydrogen is just one piece of the puzzle and it will be necessary to seek solutions that bring the whole energy system together – including not just heat for buildings but hard-to decarbonise areas such as manufacturing road transport aviation and shipping. Here we bring you just a taste of some of the amazing work taking place across the energy sector to understand this fuel more clearly to comprehend its strengths and limitations and to integrate it into our current energy infrastructure. We hope you enjoy this special publication.
Industrial Decarbonisation Strategy
Mar 2021
Publication
The UK is a world leader in the fight against climate change. In 2019 we became the first major economy in the world to pass laws to end its contribution to global warming by 2050. Reaching this target will require extensive systematic change across all sectors including industry. We must get this change right as the products made by industry are vital to life in the UK and the sector supports local economies across the country.<br/><br/>This strategy covers the full range of UK industry sectors: metals and minerals chemicals food and drink paper and pulp ceramics glass oil refineries and less energy-intensive manufacturing. These businesses account for around one sixth of UK emissions and transformation of their manufacturing processes is key if we are to meet our emissions targets over the coming decades (BEIS Final UK greenhouse gas emissions from national statistics: 1990 to 2018: Supplementary tables 2020).<br/><br/>The aim of this strategy is to show how the UK can have a thriving industrial sector aligned with the net zero target without pushing emissions and business abroad and how government will act to support this. An indicative roadmap to net zero for UK industry based on the content in this strategy is set out at the end of this summary. This strategy is part of a series of publications from government which combined show how the net zero transition will take place across the whole UK economy.
Getting Net Zero Done- The Crucial Role of Decarbonised Gas and How to Support It
May 2020
Publication
The term ‘decarbonised gas’ refers to biogases hydrogen and carbon capture utilisation and storage (CCUS). This strategy paper sets out how decarbonised gas can help to get net zero done by tackling the hard-to-decarbonise sectors – industry heavy transport and domestic heating – which together account for around 40% of UK greenhouse gas emissions. It also illustrates the crucial importance of supportive public opinion and sets out in detail how decarbonised gas can help to ensure that net zero is achieved with public support. The report is based on extensive quantitative and qualitative opinion research on climate change in general net zero emissions in the UK and the specific decarbonised gas solutions in homes transport and industry. The full quantitative data is contained in the Supplements tab.<br/><a href="https://www.dgalliance.org/wp-content/uploads/2020/05/DGA-Getting-Net-Zero-Done-final-May-2020.pdf"/><a href="https://www.dgalliance.org/wp-content/uploads/2020/05/DGA-Getting-Net-Zero-Done-final-May-2020.pdf"/>
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.
Combustion and Exhaust Emission Characteristics, and In-cylinder Gas Composition, of Hydrogen Enriched Biogas Mixtures in a Diesel Engine
Feb 2017
Publication
This paper presents a study undertaken on a naturally aspirated direct injection diesel engine investigating the combustion and emission characteristics of CH4-CO2 and CH4-CO2 -H2 mixtures. These aspirated gas mixtures were pilot-ignited by diesel fuel while the engine load was varied between 0 and 7 bar IMEP by only adjusting the flow rate of the aspirated mixtures. The in-cylinder gas composition was also investigated when combusting CH4-CO2 and CH4-CO2-H2 mixtures at different engine loads with in cylinder samples collected using two different sampling arrangements. The results showed a longer ignition delay period and lower peak heat release rates when the proportion of CO2 was increased in the aspirated mixture. Exhaust CO2 emissions were observed to be higher for 60 CH4:40CO2 mixture but lower for the 80CH4:20CO2 mixture as compared to diesel fuel only combustion at all engine loads. Both exhaust and in-cylinder NOx levels were observed to decrease when the proportion of CO2 was increased; NOx levels increased when the proportion of H2 was increased in the aspirated mixture. In-cylinder NOx levels were observed to be higher in the region between the sprays as compared to within the spray core attributable to higher gas temperatures reached post ignition in that region.
Pathways to Net-Zero: Decarbonising the Gas Networks in Great Britain
Oct 2019
Publication
Natural gas plays a central role in the UK energy system today but it is also a significant source of greenhouse gas (GHG) emissions. The UK committed in 2008 to reduce GHG emissions by at least 80% compared to 1990 levels by 2050. In June 2019 a more ambitious target was adopted into law and the UK became the first major economy to commit to “net-zero” emissions by 2050. In this context the Energy Networks Association (ENA) commissioned Navigant to explore the role that the gas sector can play in the decarbonisation of the Great Britain (GB) energy system. In this report we demonstrate that low carbon and renewable gases can make a fundamental contribution to the decarbonisation pathway between now and 2050.
Reducing Emissions in Scotland – 2016 Progress Report
Sep 2016
Publication
This is the Committee’s fifth report on Scotland’s progress towards meeting emission reduction targets as requested by Scottish Ministers under the Climate Change (Scotland) Act 2009.<br/>The Scottish Act sets a long-term target to reduce emissions of greenhouse gases (GHGs) by at least 80% in 2050 relative to 1990 with an interim target to reduce emissions by 42% in 2020. Secondary legislation passed in October 2010 and October 2011 also set a series of annual emission reduction targets for 2010 to 2022 and 2023 to 2027 respectively. We advised the Scottish Government on annual targets for the period 2028 to 2032 in March 2016 and July 2016.<br/>The report reveals that Scotland’s annual emissions reduction target for 2014 was met with gross Scottish greenhouse gas emissions including international aviation and shipping falling by 8.6% in 2014. This compares to a 7.3% fall for the UK as a whole. Since 1990 gross Scottish emissions have fallen nearly 40% compared to nearly 33% at a UK level.

Webinar to Launch New Hydrogen Economy - Hope or Hype?
Jun 2019
Publication
On 26 June the World Energy Council held a webinar presenting the results of its latest Innovation Insights Brief on hydrogen engaging three key experts on the topic:
Nigel Brandon Dean of the Faculty of Engineering Imperial College London
Craig Knight Director of Industrial Solutions Horizon Fuel Cell Technology
Dan Sadler H21 Project Manager for Equinor
During the webinar the experts answered a series of policy technical and safety questions from the audience. The webinar started with a poll to get a sense of which sectors attendees saw hydrogen playing a key role in 2040 - 77% chose industrial processes 54% mobility and 31% power generation. The questions ranged from the opportunities and limitations of blending hydrogen with natural gas to safety concerns surrounding hydrogen.
KEY HIGHLIGHTS:
How much hydrogen can be blended with natural gas depends on the rules and regulation of each country. The general consensus is that blending 10% by volume of hydrogen presents no safety concerns or specific difficulties. This would provide an opportunity to develop low hydrogen markets. Nevertheless blending should not be the end destination. It is not sufficient to meet carbon abatement targets.
Low carbon ammonia has a role to play in the new hydrogen economy. It is a proven and understood technology which is easier to move around the world and could be used directly as ammonia or cracked back into hydrogen.
One of the main focus today should be to replace grey hydrogen with green hydrogen in existing supply chains as there would be no efficiency losses in the process.
In China the push for hydrogen is transport-related. This is driven by air quality and energy independence concerns. In the next 10 years the full life cost of fuel cell electric vehicles (FCEVs) is expected to be lower than for internal combustion engines. This is due to the fact that FCEVs require less maintenance and that the residual value in the fuel cells is relatively high. At the end of life 95% of the platinum in fuel cells can be repurposed.
FCEVs should not be regarded as competing with battery electric vehicles they sit next to each other on product maps. FCEVs can benefit from the all of the advances in electric drive train systems and electric motors.
To close the webinar attendees were asked whether hydrogen was going through another hype cycle or if it was here to stay. 10% answered hype and 90% here to stay.

Differentiating Gas Leaks from Normal Appliance Use
Jun 2021
Publication
DNV has carried out an investigation into potential uses for smart gas meter data as part of Phase 1 of the Modernising Energy Data Applications competition as funded by UK Research & Innovation. In particular a series of calculations have been carried out to investigate the possibility of differentiating accidental gas leaks from normal appliance use in domestic properties. This is primarily with the aim of preventing explosions but the detection of leaks also has environmental and financial benefits.
Three gases have been considered in this study:
An examination of detailed historical incident information suggests that the explosions that lead to fatalities or significant damage to houses are typically of the type that would be more likely to be detected and prevented. It is estimated that between 25% and 75% of the more severe explosions could be prevented depending on which potential improvements are implemented.
Based on the conservative estimates of explosion prevention a cost benefit analysis suggests that it is justifiable to spend between around £1 and £10 per meter installed to implement the proposed technology. This is based purely on lives saved and does not take account of other benefits.
Three gases have been considered in this study:
- A representative UK natural gas composition.
- A blend of 80% natural gas and 20% hydrogen.
- Pure hydrogen.
- Small holes of up to 1 mm rarely reach flammable gas/air concentrations for any gas except under the most unfavourable conditions such as small volumes combined with low ventilation rates. These releases would likely be detected within 6 to 12 hours.
- Medium holes between 1 mm and 6 mm give outflow rates equivalent to a moderate to high level of gas use by appliances. The ability to detect these leaks is highly dependent on the hole size the time at which the leak begins and the normal gas use profile in the building. The larger leaks in this category would be detected within 30 to 60 minutes while the smaller leaks could take several hours to be clearly differentiated from appliance use. This is quick enough to prevent some explosions.
- Large holes of over 6 mm give leak rates greater than any gas use by appliances. These releases rapidly reach a flammable gas/air mixture in most cases but would typically be detected within the first 30-minute meter output period. Again some explosions could be prevented in this timescale.

Overview
Findings from this groundbreaking analysis of the future net zero energy system in Great Britain are expected to have profound implications for policymakers households and the wider energy sector across Great Britain.
Key findings include:
- Embedding greater flexibility across the entire energy system will reduce the cost of achieving net zero for all consumers while assuring energy security.
- Investing in flexibility is a no-regrets decision as it has the potential to deliver material net savings of up to £16.7bn per annum across all scenarios analysed in 2050.
- A more flexible system will accelerate the benefits of decarbonisation supported by decentralisation and digitalisation.
- To maximise the benefits of flexibility households and businesses should play an active role in the development and operation of the country’s future energy system as energy use for transport heat and appliances becomes more integrated.
- Policymakers should preserve existing flexibility options and act now to maximise future flexibility such as by building it into ‘smart’ appliances or building standards.

Impact Assessment of Hydrogen on Transmission Pipeline BPDs in IGEM/TD/1
Jul 2021
Publication
As part of the LTS Futures HyTechnical project IGEM requested that DNV GL undertake an assessment of the possible impact of hydrogen transmission on BPDs to support the development of supplements to the existing suite of natural gas standards to accommodate the possible future use of hydrogen. The current state of knowledge of the behaviour of large scale high pressure hydrogen releases is limited in comparison with the considerable body of data from research and operational experience of natural gas but is adequate to undertake an impact assessment to take account of the different gas outflow and fire characteristics of 100% hydrogen vs. natural gas.<br/>Calculations of the BPDs for 100% hydrogen pipeline fires on an equivalent basis to those in IGEM/TD/1 for natural gas have been performed with a degree of confidence in the results and demonstrated that the equivalent BPDs for 100% hydrogen are approximately 10% smaller than for natural gas. The results are presented graphically in this report.<br/>However hydrogen introduces the potential for substantially higher overpressures than natural gas due to the higher flame speed and wider flammable limits if delayed ignition is a credible event. The overpressure estimates presented in this report are intended to be scoping calculations to put the likely overpressures into context. The results suggest that significant overpressures are possible at the BPDs but there is a lack of evidence to support the estimation of the overpressures following delayed ignition of a large turbulent hydrogen release in the open (in contrast to explosions in confined or congested regions) and there is a high degree of uncertainty in the predictions presented here. It is therefore recommended that large scale pipeline rupture experiments are performed similar to those undertaken previously for hydrogen natural gas and natural gas/hydrogen mixtures but with ignition engineered to take place after a short delay in order to measure the overpressures and provide the means to validate or refine the predictions made.<br/>The analysis has highlighted limitations in the original method of calculating BPDs in IGEM/TD/1 which reflects the techniques available at the time approximately 40 years ago. Since then understanding of the hazards from pipeline failures and the ability to model the consequences and predict the associated risks to people in the surrounding area have advanced very considerably facilitated by software tools and documented in standards such as IGEM/TD/2. These methods allow the highly transient nature of a high pressure gas pipeline rupture release to be modelled more accurately and for the thermal effects of fires on people and buildings to be calculated taking account of the time-varying thermal dose.<br/>For these reasons a simple comparison of the possible overpressure effects of delayed ignition of a 100% hydrogen release at the BPDs can be misleading and implies that the overpressure hazards could be more severe than those for fires which may not be the case. Example calculations have been performed for a representative pipeline case which indicate that using current methods the predicted thermal hazard distances for 100% hydrogen pipeline fires (house burning and escape for people) are substantially greater than those estimated for overpressures following delayed ignition for similar levels of vulnerability. This report addresses buried pipelines only – the potential for more severe explosion overpressure effects for hydrogen releases may be more significant for Above Ground Installations (AGIs) especially where congestion or confinement may be present. It is recommended that similar studies are conducted to quantify the effect of hydrogen conversion on the consequences and risks associated with hydrogen releases at AGIs.<br/>Finally it is stressed that the analysis in this report does not consider the relative risks for 100% hydrogen and the equivalent natural gas pipelines. There remain uncertainties in the failure frequencies for steel pipelines transporting hydrogen and particularly the probability of immediate and delayed ignition. The likelihood of delayed ignition of a large turbulent high pressure hydrogen gas pipeline rupture release may be very low due to the wider flammability limits and lower minimum ignition energy for hydrogen compared with natural gas. Additional research is currently ongoing or planned to address the gaps in knowledge for 100% hydrogen which should allow more robust comparisons of the relative risks to be made in the future.
Public Acceptability of the Use of Hydrogen for Heating and Cooking in the Home: Results from Qualitative and Quantitative Research in UK<br/>Executive Summary
Nov 2018
Publication
This report for the CCC by Madano and Element Energy assesses the public acceptability of two alternative low-carbon technologies for heating the home: hydrogen heating and heat pumps.
These technologies could potentially replace natural gas in many UK households as part of the government’s efforts to decrease carbon emissions in the UK.
The report’s key findings are:
These technologies could potentially replace natural gas in many UK households as part of the government’s efforts to decrease carbon emissions in the UK.
The report’s key findings are:
- carbon emissions reduction is viewed as an important issue but there is limited awareness of the need to decarbonise household heating or the implications of switching over to low-carbon heating technologies
- acceptability of both heating technologies is limited by a lack of perceived tangible consumer benefit which has the potential to drive scepticism towards the switch over more generally
- heating technology preferences are not fixed at this stage although heat pumps appear to be the favoured option in this research studythree overarching factors were identified as influencing preferences for heating technologies.
- perceptions of the negative installation burden
- familiarity with the lived experience of using the technologies for heating
- perceptions of how well the technologies would meet modern heating needs both hydrogen heating and heat pumps face significant challenges to secure public acceptability

The Impact of Disruptive Powertrain Technologies on Energy Consumption and Carbon Dioxide Emissions from Heavy-duty Vehicles
Jan 2020
Publication
Minimising tailpipe emissions and the decarbonisation of transport in a cost effective way remains a major objective for policymakers and vehicle manufacturers. Current trends are rapidly evolving but appear to be moving towards solutions in which vehicles which are increasingly electrified. As a result we will see a greater linkage between the wider energy system and the transportation sector resulting in a more complex and mutual dependency. At the same time major investments into technological innovation across both sectors are yielding rapid advancements into on-board energy storage and more compact/lightweight on-board electricity generators. In the absence of sufficient technical data on such technology holistic evaluations of the future transportation sector and its energy sources have not considered the impact of a new generation of innovation in propulsion technologies. In this paper the potential impact of a number of novel powertrain technologies are evaluated and presented. The analysis considers heavy duty vehicles with conventional reciprocating engines powered by diesel and hydrogen hybrid and battery electric vehicles and vehicles powered by hydrogen fuel cells and freepiston engine generators (FPEGs). The benefits are compared for each technology to meet the expectations of representative medium and heavy-duty vehicle drivers. Analysis is presented in terms of vehicle type vehicle duty cycle fuel economy greenhouse gas (GHG) emissions impact on the vehicle etc.. The work shows that the underpinning energy vector and its primary energy source are the most significant factor for reducing primary energy consumption and net CO2 emissions. Indeed while an HGV with a BEV powertrain offers no direct tailpipe emissions it produces significantly worse lifecycle CO2 emissions than a conventional diesel powertrain. Even with a de-carbonised electricity system (100 g CO2/kWh) CO2 emissions are similar to a conventional Diesel fuelled HGV. For the HGV sector range is key to operator acceptability of new powertrain technologies. This analysis has shown that cumulative benefits of improved electrical powertrains on-board storage efficiency improvements and vehicle design in 2025 and 2035 mean that hydrogen and electric fuelled vehicles can be competitive on gravimetric and volumetric density. Overall the work demonstrates that presently there is no common powertrain solution appropriate for all vehicle types but how subtle improvements at a vehicle component level can have significant impact on the design choices for the wider energy system.
UK Climate Action Following the Paris Agreement
Oct 2016
Publication
The Paris Agreement marks a significant positive step in global action to tackle climate change. This report considers the domestic actions the UK Government should take as part of a fair contribution to the aims of the Agreement.<br/>The report concludes that the Paris Agreement is a significant step forward in global efforts to tackle climate change. It is more ambitious in its aims to limit climate change than the basis of the UK’s existing climate targets. However it is not yet appropriate to set new UK targets. Existing targets are already stretching and the priority is to take action to meet them.
Decarbonisation of Heat in Great Britain
Oct 2021
Publication
This study was conducted for a group of 15 clients in the public and private sectors interested in potential pathways for decarbonising residential heating and the impact of these pathways on the energy system. The ambition for all new heating installations to be low carbon from 2035 is essential to meeting the net zero target in 2050 and our study found that electricity demand for home heating is set to quadruple by 2050 as part of the shift away from gas-fired boilers.
The key findings from the study include:
The key findings from the study include:
- Phasing out natural gas boiler installations by 2035 is crucial for eliminating CO2 from home heating; delaying to 2040 could leave us with ¼ of today’s home heat emissions in 2050
- Achieving deployment of 600k heat pumps per year by 2028 will require policy intervention both to lower costs and to inform and protect consumers Almost £40bn could be saved in cumulative system costs by 2050 through adoption of more efficient and flexible electric heating technologies like networked heat pumps and storage
- Electricity demand from heating could quadruple by 2050 to over 100TWh per year almost a third of Great Britain’s current total annual electricity demand Using hydrogen for a share of heating could lower peak power demand although producing most of this hydrogen from electrolysis would raise overall power demand.
H2FC SUPERGEN- The Role of Hydrogen and Fuel Cells in Providing Affordable, Secure Low-carbon Heat
May 2014
Publication
This White Paper has been commissioned by the UK Hydrogen and Fuel Cell (H2FC) SUPERGEN Hub to examine the roles and potential benefits of hydrogen and fuel cell technologies for heat provision in future low-carbon energy systems. The H2FC SUPERGEN Hub is an inclusive network encompassing the entire UK hydrogen and fuel cells research community with around 100 UK-based academics supported by key stakeholders from industry and government. It is funded by the UK EPSRC research council as part of the RCUK Energy Programme. This paper is the first of four that will be published over the lifetime of the Hub with the others examining: (i) low-carbon energy systems (including balancing renewable intermittency); (ii) low-carbon transport systems; and (iii) the provision of secure and affordable energy supplies for the future
- Hydrogen and fuel cells are part of the cost-optimal heating technology portfolio in long-term UK energy system scenarios.
- Fuel cell CHP is already being deployed commercially around the world.
- Hydrogen can be a zero-carbon alternative to natural gas. Most technologies that use natural gas can be adapted to use hydrogen and still provide the same level of service.
- Hydrogen and fuel cell technologies avoid some of the disadvantages of other low-carbon heating technologies.
SGN Project Report - Flame Visibility Risk Assessment
Feb 2021
Publication
This report contains information on the relative risks of natural gas and hydrogen fires particularly regarding their visibility. The fires considered are those that could occur on the H100 Fife trial network. The H100 Fife project will connect a number of residential houses to 100% hydrogen gas supply. The project includes hydrogen production storage and a new distribution network. From a review of large and small-scale tests and incidents it is concluded that hydrogen flames are likely to be clearly visible for releases above 2 bar particularly for larger release rates. At lower pressures hydrogen flame visibility will be affected by ambient lighting background colour and release orientation although this is also the case for natural gas. Potential safety implications from lack of flame visibility are that SGN workers other utility workers or members of the public could inadvertently come into contact with an ignited release. However some releases would be detected through noise thrown soil or interaction with objects. From a workshop and review of risk reduction measures and analysis of historical interference damage incidents it is concluded that flames with the potential for reduced visibility are adequately controlled. This is due to the likelihood of such scenarios occurring being low and that the consequences of coming into contact with such a flame are unlikely to be severe. These conclusions are supported by cost-benefit analysis that shows that no additional risk mitigation measures are justified for the H100 project. It is recommended that the cost-benefit analysis is revisited before applying the approach to a network wider than the H100 project. It was observed that the addition of odorant at relevant concentrations did not have an effect on the visibility of hydrogen flames.
