HyNet North West is a significant clean growth opportunity for the UK. It is a low cost deliverable project which meets the major challenges of reducing carbon emissions from industry domestic heat and transport.<br/>HyNet North West is based on the production of hydrogen from natural gas. It includes the development of a new hydrogen pipeline; and the creation of the UK’s first carbon capture and storage (CCS) infrastructure. CCS is a vital technology to achieve the widespread emissions savings needed to meet the 2050 carbon reduction targets.<br/>Accelerating the development and deployment of hydrogen technologies and CCS through HyNet North West positions the UK strongly for skills export in a global low carbon economy.<br/>The North West is ideally placed to lead HyNet. The region has a history of bold innovation and today clean energy initiatives are thriving. On a practical level the concentration of industry existing technical skill base and unique geology means the region offers an unparalleled opportunity for a project of this kind.<br/>The new infrastructure built by HyNet is readily extendable beyond the initial project and provides a replicable model for similar programmes across the UK<br/>Contains Vision statement 2 leaflets a presentation and a summary report which are all stored as supplements.

Hydrogen is essential to the UK meeting its net zero emissions target. We must act now to scale hydrogen solutions and achieve cost effective deep decarbonisation. With the support of Government UK industry is ready to deliver.

The potential to deploy hydrogen at scale as an energy vector has risen rapidly in the political and industrial consciousness in recent years as the benefits and opportunities have become better understood. Early stage projects across the globe have demonstrated the potential of hydrogen to deliver deep decarbonisation reduce the cost of renewable power and balance energy supply and demand. Governments and major industrial and commercial organisations across the world have set out their ambition to deploy hydrogen technologies at scale. This has created a growing confidence that hydrogen will present both a viable decarbonisation pathway and a global market opportunity. Hydrogen will have an important role to play in meeting the global climate goals set out in the Paris Climate Agreement and due to be discussed later this year at COP26.

The UK’s commitment to a net zero greenhouse gas emissions target has sharpened the conversation around hydrogen. Most experts agree that net zero by 2050 cannot be achieved through electrification alone and as such there is a need for a clean molecule to complement the electron. Hydrogen has properties which lend themselves to the decarbonisation of parts of the energy system which are less well suited to electrification such as industrial processes heating and heavy and highly utilised vehicles. Hydrogen solutions can be scaled meaning that the contribution of hydrogen to meeting net zero could be substantial.

A steady start has been made to exploring the hydrogen opportunity. Partnerships between policymakers and industry exist on several projects which are spread out right across the country from London to many industrial areas in the north east and north west. Existing projects include the early stage roll out of transport infrastructure and vehicles feasibility studies focused on large scale hydrogen production technologies projects exploring the decarbonisation of the gas grid and the development of hydrogen appliances.

The Government recently announced new funding for hydrogen through the Hydrogen Supply Programme and Industrial Fuel Switching Competition. These programmes are excellent examples of collaboration between Government and industry in driving UK leadership in hydrogen and developing solutions that will be critical for meeting net zero.

If the UK is going to meet net zero and capitalise on the economic growth opportunities presented by domestic and global markets for hydrogen solutions and expertise it is critical that the 2020s deliver a step change in hydrogen activity building on the unique strengths and expertise developed during early stage technology development.

The Hydrogen Taskforce brings together leading companies pushing hydrogen into the mainstream in the UK to offer a shared view of the opportunity and a collective position on the next steps that must be taken to ensure that the UK capitalises on this opportunity. There are questions to be answered and challenges that must be overcome as hydrogen technologies develop yet by focusing on what can be done today the benefits of hydrogen can be immediately realised whilst industry expertise and knowledge is built.

The objective of the analysis is to provide a robust assessment of the economic impact of HyNet NW over the period to 2050 across both the North West of England and the UK as a whole. Impact is assessed through modelling of direct indirect and induced effect frameworks:

• Direct effects – activities that directly accrue due to the construction and operation of the facilities;
• Indirect effects – the purchase of goods and services to facilitate construction/operation; and
• Induced effects – spending of wages and salaries generated directly and indirectly through construction and operation.

The approach taken is to define the capital and operating expenditure (CAPEX and OPEX) profiles of the Project investment as the basis of analysis distinguishing where feasible between design construction and equipment costs and establishing the likely sourcing of these activities from within the North West UK and overseas.

Consideration is also given to the potential impacts of inward investment attracted to the North West/UK in the wake of the Project.

Seizing the clean growth opportunity. The move to cleaner economic growth is one of the greatest industrial opportunities of our time. This Strategy will ensure Britain is ready to seize that opportunity. Our modern Industrial Strategy is about increasing the earning power of people in every part of the country. We need to do that while not just protecting but improving the environment on which our economic success depends. In short we need higher growth with lower carbon emissions. This approach is at the heart of our Strategy for clean growth. The opportunity for people and business across the country is huge. The low carbon economy could grow 11 per cent per year between 2015 and 2030 four times faster than the projected growth of the economy as a whole. This is spread across a large number of sectors: from low cost low carbon power generators to more efficient farms; from innovators creating better batteries to the factories putting them in less polluting cars; from builders improving our homes so they are cheaper to run to helping businesses become more productive. This growth will not just be seen in the UK. Following the success of the Paris Agreement where Britain played such an important role in securing the landmark deal the transition to a global low carbon economy is gathering momentum. We want the UK to capture every economic opportunity it can from this global shift in technologies and services.<br/>Our approach to clean growth is an important element of our modern Industrial Strategy: building on the UK’s strengths; improving productivity across the country; and ensuring we are the best place for innovators and new businesses to start up and grow. A good example of this is offshore wind where costs have halved in just a few years. A combination of sustained commitment – across different Governments – and targeted public sector innovation support harnessing the expertise of UK engineers working in offshore conditions and private sector ingenuity has created the conditions for a new industry to flourish while cutting emissions. We need to replicate this success in sectors across our economy. This Strategy delivers on the challenge that Britain embraced when Parliament passed the Climate Change Act. If we get it right we will not just deliver reduced emissions but also cleaner air lower energy bills for households and businesses an enhanced natural environment good jobs and industrial opportunity. It is an opportunity we will seize.

The development of new infrastructure is often a consideration in the introduction of new innovations. Currently there is some confusion around how to develop a hydrogen infrastructure to support the introduction of FCVs. Lessons can be learned from similar technology introduction in the past and therefore this paper investigates how mobile phone infrastructure was developed allowing the mass-market penetration of mobile phones. Based on this successful infrastructural development suggestions can be made on the development of a hydrogen infrastructure. It is suggested that a hydrogen infrastructure needs to be pre-developed 3–5 years before the market introduction of FCVs can successfully occur. A lack of infrastructural pre-development will cause to the market introduction of FCVs to fail.

Our mission is to put the UK at the forefront of the design and manufacturing of zero emission vehicles and for all new cars and vans to be effectively zero emission by 2040. As set out in the NO2 plan we will end the sale of new conventional petrol and diesel cars and vans by 2040. By then we expect the majority of new cars and vans sold to be 100% zero emission and all new cars and vans to have significant zero emission capability. By 2050 we want almost every car and van to be zero emission. We want to see at least 50% and as many as 70% of new car sales and up to 40% of new van sales being ultra low emission by 2030.<br/>We expect this transition to be industry and consumer led supported in the coming years by the measures set out in this strategy. We will review progress towards our ambitions by 2025. Against a rapidly evolving international context we will seek to maintain the UK’s leadership position and meet our ambitions and will consider what interventions are required if not enough progress is being made.

This study presents a computational fluid dynamic (CFD) study of Dimethyl Ether steam reforming (DME-SR) in a large scale Circulating Fluidized Bed (CFB) reactor. The CFD model is based on Eulerian–Eulerian dispersed flow and solved using commercial software (ANSYS FLUENT). The DME-SR reactions scheme and kinetics in the presence of a bifunctional catalyst of CuO/ZnO/Al₂O₃+ZSM-5 were incorporated in the model using in-house developed user-defined function. The model was validated by comparing the predictions with experimental data from the literature. The results revealed for the first time detailed CFB reactor hydrodynamics gas residence time temperature distribution and product gas composition at a selected operating condition of 300 °C and steam to DME mass ratio of 3 (molar ratio of 7.62). The spatial variation in the gas species concentrations suggests the existence of three distinct reaction zones but limited temperature variations. The DME conversion and hydrogen yield were found to be 87% and 59% respectively resulting in a product gas consisting of 72 mol% hydrogen. In part II of this study the model presented here will be used to optimize the reactor design and study the effect of operating conditions on the reactor performance and products.

Explosion venting is a method commonly used to prevent or minimize damage to an enclosure caused by an accidental explosion. An estimate of the maximum overpressure generated though explosion is an important parameter in the design of the vents. Various engineering models (Bauwens et al. 2012 Molkov and Bragin 2015) and European (EN 14994 ) and USA standards (NFPA 68) are available to predict such overpressure. In this study their performance is evaluated using a number of published experiments. Comparison of pressure predictions from various models have also been carried out for the recent experiments conducted by GexCon using a 20 feet ISO container. The results show that the model of Bauwens et al. (2012) predicts well for hydrogen concentration between 16% and 21% and in the presence of obstacles. The model of Molkov et al. (2015) is found to work well for hydrogen concentrations between 10% and 30% without obstacles. In the presence of obstacles as no guidelines are given to set the coefficient for obstacles in the model it was necessary to tune the coefficient to match the experimental data. The predictions of the formulas in NFPA 68 show a large scatter across different tests. The current version of both EN 14994 and NFPA 68 are found to have very limited range of applicability and can hardly be used for vent sizing of hydrogen-air deflagrations. Overall the accuracy of all the engineering models was found to be limited. Some recommendations concerning their applicability will be given for vented lean-hydrogen explosion concentrations of interest to practical applications.

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

The THyGA project (‘Testing Hydrogen admixture for Gas Applications’) focusses on technical aspects and the regulatory framework concerning the potential operation of domestic and commercial end-user appliances with hydrogen / natural gas blends.<br/>The core of the project is a broad experimental campaign with the aim to conduct up to 100 hydrogen tolerance tests. In addition the technical status quo and present knowledge about hydrogen impact on domestic and commercial appliances are assessed and potential future developments of rules and standards are discussed. Also mitigation strategies for coping with high levels of hydrogen admixture will be developed. By this broad approach the project aims at investigating which levels of hydrogen blending impact the various appliance technologies and to which extent in order to identify the regime in which a safe efficient and low-polluting operation is possible.<br/>The series of public reports by the THyGA project starts with several publications from work package 2 which sets the basis for the upcoming results and discussion of the experimental campaign as well as mitigation and standardisation topics.<br/>This report D2.5 completes the series of public reports from work package 2. It explains the steps of development of the test programme for gas-fired appliance tests with hydrogen admixture and especially describes the exchange between the THyGA partners and the external stakeholders.<br/>The report also explains the process of acquisition of appliances to test and method of selecting appliances.

The trial management philosophy of the Winlaton trial within HyDeploy2 has been developed to enable the overall objectives of the project to be achieved; the safe demonstration of operating a Gas Distribution Network (GDN) on a blend of natural gas and hydrogen. The approach taken to develop the management philosophy of the Winlaton trial has been to continue the trial management strategies deployed for the Keele trial under HyDeploy albeit with site specific modifications where necessary. This document provides an overview of the management and governance processes associated with the trial itself.<br/>Click on the supplement tab to view the other documents from this report

In the event of a fire composite pressure vessels behave very differently from metallic ones: the material is degraded potentially leading to a burst without significant pressure increase. Hence such objects are when necessary protected from fire by using thermally-activated devices (TPRD) and standards require testing cylinder and TPRD together. The pre-normative research project FireComp aimed at understanding better the conditions which may lead to burst through testing and simulation and proposed an alternative way of assessing the fire performance of composite cylinders. This approach is currently used by Air Liquide for the safety of composite bundles carrying large amounts of hydrogen gas.

Metal hydrides are known as a potential efficient low-risk option for high-density hydrogen storage since the late 1970s. In this paper the present status and the future perspectives of the use of metal hydrides for hydrogen storage are discussed. Since the early 1990s interstitial metal hydrides are known as base materials for Ni – metal hydride rechargeable batteries. For hydrogen storage metal hydride systems have been developed in the 2010s [1] for use in emergency or backup power units i. e. for stationary applications.<br/>With the development and completion of the first submarines of the U212 A series by HDW (now Thyssen Krupp Marine Systems) in 2003 and its export class U214 in 2004 the use of metal hydrides for hydrogen storage in mobile applications has been established with new application fields coming into focus.<br/>In the last decades a huge number of new intermetallic and partially covalent hydrogen absorbing compounds has been identified and partly more partly less extensively characterized.<br/>In addition based on the thermodynamic properties of metal hydrides this class of materials gives the opportunity to develop a new hydrogen compression technology. They allow the direct conversion from thermal energy into the compression of hydrogen gas without the need of any moving parts. Such compressors have been developed and are nowadays commercially available for pressures up to 200 bar. Metal hydride based compressors for higher pressures are under development. Moreover storage systems consisting of the combination of metal hydrides and high-pressure vessels have been proposed as a realistic solution for on-board hydrogen storage on fuel cell vehicles.<br/>In the frame of the “Hydrogen Storage Systems for Mobile and Stationary Applications” Group in the International Energy Agency (IEA) Hydrogen Task 32 “Hydrogen-based energy storage” different compounds have been and will be scaled-up in the near future and tested in the range of 500 g to several hundred kg for use in hydrogen storage applications.

You will also hear about the need to build up scale for hydrogen production and supply in tandem with hydrogen pipeline and distribution networks in order to meet demand for low carbon energy and achieve key milestones on the pathway to Net Zero by 2045.

Hydrogen storage in nanoporous materials has been attracting a great deal of attention in recent years as high gravimetric H2 capacities exceeding 10 wt% in some cases can be achieved at 77 K using materials with particularly high surface areas. However volumetric capacities at low temperatures and both gravimetric and volumetric capacities at ambient temperature need to be improved before such adsorbents become practically viable. This article therefore discusses approaches to increasing the gravimetric and volumetric hydrogen storage capacities of nanoporous materials and maximizing the usable capacity of a material between the upper storage and delivery pressures. In addition recent advances in machine learning and data science provide an opportunity to apply this technology to the search for new materials for hydrogen storage. The large number of possible component combinations and substitutions in various porous materials including Metal-Organic Frameworks (MOFs) is ideally suited to a machine learning approach; so this is also discussed together with some new material types that could prove useful in the future for hydrogen storage applications.

Objectives

The aim of this review is to establish which available literature may be of use as part of the HSE funded project which will investigate spontaneous ignition of accidental hydrogen releases (JR02071). It will identify  phenomena that have the potential to cause spontaneous ignition of releases of pressured hydrogen and identify literature that may be of use when formulating the experimental program.

Main Findings

The identification of important work that shows conclusive evidence of spontaneous ignition of hydrogen due to the failure of a boundary layer.

The HYPER project a specific targeted research project (STREP) funded by the European Commission under the Sixth Framework Programme developed an Installation Permitting Guide (IPG) for hydrogen and fuel cell stationary applications. The IPG was developed in response to the growing need for guidance to foster the use and facilitate installation of these systems in Europe. This document presents a modified version of the IPG specifically intended for the UK market. For example reference is made to UK national regulations standards and practices when appropriate as opposed to European ones.<br/>The IPG applies to stationary systems fuelled by hydrogen incorporating fuel cell devices with net electrical output of up to 10 kWel and with total power outputs of the order of 50 kW (combined heat + electrical) suitable for small back up power supplies residential heating combined heat-power (CHP) and small storage systems. Many of the guidelines appropriate for these small systems will also apply to systems up to 100 kWel which will serve small communities or groups of households. The document is not a standard but is a compendium of useful information for a variety of users with a role in installing these systems including design engineers manufacturers architects installers operators/maintenance workers and regulators.<br/>This report and the work it describes were funded by the Health and Safety Executive (HSE). Its contents including any opinions and/or conclusions expressed are those of the authors alone and do not necessarily reflect HSE policy.

THIS ANNUAL SCIENCE Review showcases the high quality of science evidence and analysis that underpins HSE’s risk-based regulatory regime. To be an effective regulator HSE has to balance its approaches to informing directing advising and enforcing through a variety of activities. For this we need capacity to advance knowledge; to develop and use robust evidence and analysis; to challenge thinking; and to review effectiveness.<br/>In simple terms policy provides the route map to tackling issues. HSE is particularly well placed in terms of the three components of effective policy - “politics” “evidence” and “delivery”. Unlike most regulators and arms-length bodies HSE leads on policy development which draws directly on front line delivery expertise and intelligence; and we are also unusual in having our own world class science and insight capabilities.<br/>The challenge is to ensure we bring these components together to best effect to respond to new risk management and regulatory issues with effective innovative and proportionate approaches.<br/>Many of the articles in this Review relate to new and emerging technologies and the changing world of work and it is important to understand the risks these may pose and how they can be effectively controlled or how they themselves can contribute to improved health and safety in the workplace. Good policy development can support approaches to change that are proportionate relevant persuasive and effective. For example work described in these pages is: to help understand changing workplace exposures; to provide robust evidence to those negotiating alternatives to unduly prescriptive standards; to understand how best to influence duty<br/>holder behaviors in the changing world of work; to inform possible legislative changes to allow different modes of safe gas transmission; to change administrative processes for Appointed Doctors; and to support our position as a model modern regulator by further focusing our inspection activity where it matters most.<br/>The vital interface between HSE science and policy understand how best to influence duty holder behaviors in the changing world of work; to inform possible legislative changes to allow different modes of safe gas transmission; to change administrative processes for Appointed Doctors; and to support our position as a model modern regulator by further focusing our inspection activity where it matters most.<br/>We work well together and it is important we maintain this engagement as a conscious collaboration.

In the long term the key to the development of a hydrogen economy is a full infrastructure to support it which include means for the delivery and storage of hydrogen at the point of use eg at hydrogen refuelling stations for vehicles. As an interim measure to allow the development of refuelling stations and rapid implementation of hydrogen distribution to them liquid hydrogen is considered the most efficient and cost effective means for transport and storage.

The Health and Safety Executive have commissioned the Health and Safety Laboratory to identify and address issues relating to bulk liquid hydrogen transport and storage and update/develop guidance for such facilities. This position paper the first part of the project assesses the features of the transport and storage aspects of the refuelling stations that are now being constructed in the UK compares them to existing guidance highlights gaps in the regulatory regime and identifies outstanding safety issues. The findings together with the results of experiments to improve our understanding of the behaviour of liquid hydrogen will inform the development of the guidance for refuelling facilities

Hydrogen solutions have a critical role to play in the UK not only in helping the nation meet its net-zero target but in creating the economic growth and jobs that will kickstart the green recovery.

The Government must act now to ensure that the UK capitalises on the opportunity presented by hydrogen and builds a world-leading industry.

COVID-19 has caused significant economic upheaval across the country with unemployment expected to reach up to 14.8 per cent by the end of 20201. The UK must identify those areas of the economy which have significant economic growth potential and can deliver long-term and sustainable increases in GVA and jobs. It will be important to consider regional factors and ensure that investment is targeted in those areas that have been hardest hit by the crisis.

Many major economies have identified hydrogen as a key part of both decarbonisation and economic recovery. As part of its stimulus package Germany announced a €9billion investment in green hydrogen solutions aiming to deploy 5GW by 2030. The Hydrogen Council estimates a future hydrogen and equipment market worth $2.5 trillion globally by 2050 supporting 30 million new jobs.

Hydrogen offers the UK a pathway to deep cost-effective decarbonisation while delivering economic growth and job creation. It should therefore be at the heart of the Government’s green recovery programme ensuring that the UK builds back better and greener.

Through its “Reducing Carbon whilst Creating Social Value: How to get Started’ initiative Welsh Government is keen to explore whether a ‘circular economy’ (and industry) could be developed for Wales for CO2.<br/>Although most companies have targets to reduce their CO2 by 2030 Wales does not have the space to store or bury any excess with the current choice to ship or ‘move the problem’ elsewhere. Meanwhile other industry sectors in Wales are experiencing shortages of CO2 e.g. food production.<br/>Net Zero commitments will require dealing with CO2 emissions from agricultural and industrial sectors and from the production of blue and grey hydrogen during the transition time of switching to green hydrogen. Sequestration and shipping off of CO2 could be costly are not currently possible at large scale and are not sustainable. The use of CO2 by industry e.g. in construction materials and in food production processes can play a major role in addressing CO2 waste production from grey and blue hydrogen.<br/>In a Cradle-to-Cradle approach everything has a use. Is Wales missing out on creating and developing a new innovative industry around a CO2 circular economy?

The fuel quality of hydrogen dispensed from 10 refuelling stations in Europe was assessed. Representative sampling was conducted from the nozzle by use of a sampling adapter allowing to bleed sample gas in parallel while refuelling an FCEV. Samples were split off and distributed to four laboratories for analysis in accordance with ISO 14687 and SAE J2719. The results indicated some inconsistencies between the laboratories but were still conclusive. The fuel quality was generally good. Elevated nitrogen concentrations were detected in two samples but not in violation with the new 300 μmol/mol tolerance limit. Four samples showed water concentrations higher than the 5 μmol/mol tolerance limit estimated by at least one laboratory. The results were ambiguous: none of the four samples showed all laboratories in agreement with the violation. One laboratory reported an elevated oxygen concentration that was not corroborated by the other two laboratories and thus considered an outlier.

The location of hydrogen within Ti–Cr–V–Mo alloys has been investigated during hydrogen absorption and desorption using in situ neutron powder diffraction and inelastic neutron scattering. Neutron powder diffraction identifies a low hydrogen equilibration pressure body-centred tetragonal phase that undergoes a martensitic phase transition to a face-centred cubic phase at high hydrogen equilibration pressures. The average location of the hydrogen in each phase has been identified from the neutron powder diffraction data although inelastic neutron scattering combined with density functional theory calculations show that the local structure is more complex than it appears from the average structure. Furthermore the origin of the change in dissociation pressure and hydrogen trapping on cycling in Ti–Cr–V–Mo alloys is discussed.

At present aero engine fault diagnosis is mainly based on the steady-state condition at the cruise phase and the gas path parameters in the entire flight process are not effectively used. At the same time high quality steady-state monitoring measurements are not always available and as a result the accuracy of diagnosis might be affected. There is a recognized need for real-time performance diagnosis of aero engines operating under transient conditions which can improve their condition-based maintenance. Recent studies have demonstrated the capability of the sequential model-based diagnostic method to predict accurately and efficiently the degradation of industrial gas turbines under steady-state conditions. Nevertheless incorporating real-time data for fault detection of aero engines that operate in dynamic conditions is a more challenging task. The primary objective of this study is to investigate the performance of the sequential diagnostic method when it is applied to aero engines that operate under transient conditions while there is a variation in the bypass ratio and the heat soakage effects are taken into consideration. This study provides a novel approach for quantifying component degradation such as fouling and erosion by using an adapted version of the sequential diagnostic method. The research presented here confirms that the proposed method could be applied to aero engine fault diagnosis under both steady-state and dynamic conditions in real-time. In addition the economic impact of engine degradation on fuel cost and payload revenue is evaluated when the engine under investigation is using hydrogen. The proposed method demonstrated promising diagnostic results where the maximum prediction errors for steady state and transient conditions are less than 0.006% and 0.016% respectively. The comparison of the proposed method to a benchmark diagnostic method revealed a 15% improvement in accuracy which can have great benefit when considering that the cost attributed to degradation can reach up to $702585 for 6000 flight cycles of a hydrogen powered aircraft fleet. This study provides an opportunity to improve our understanding of aero engine fault diagnosis in order to improve engine reliability availability and efficiency by online health monitoring.

The COVID-19 pandemic has exacerbated challenges faced by hydrocarbon exporters in the Gulf owing to the global push to transition to cleaner energy sources.  In this podcast Manal Shehabi (OIES) discusses with David Ledesma a recent OIES-KFAS workshop held in April 2021 titled “Energy Transition Post-Pandemic in the Gulf States” held with support from the Kuwait Foundation for the Advancement of Sciences (KFAS).  They discuss separate but interrelated issues on clean energy economic and climate sustainability and hydrogen.  Specially they examine how the global energy transition outlook has changed post-pandemic along with its impacts on Gulf States’ economies and energy transition projects.  They explain implications to Gulf states’ sustainability evaluating whether these countries are fiscally sustainable post-pandemic and their urgent need for energy and economic diversification.  They focus in on the possibility of the Gulf States’ using hydrogen to diversify both in domestic and export markets evaluating opportunities and challenges for both blue and green hydrogen.  A preliminary case study on the economics of hydrogen in Kuwait is highlighted as indication of whether Gulf states can produce green hydrogen competitively.  They conclude with policy recommendations to increase economic sustainability and resilience post-pandemic both through the energy transition and responses to it.
