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.
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.
Prospects for the Use of Hydrogen in the Armed Forces
Oct 2021
Publication
The energy security landscape that we envisage in 2050 will be different from that of today. Meeting the future energy needs of the armed forces will be a key challenge not least for military security. The World Energy Council’s World Energy Scenarios forecast that the world’s population will rise to 10 billion by 2050 which will also necessitate an increase in the size of the armed forces. In this context energy extraction distribution and storage become essential to stabilizing the imbalance between production and demand. Among the available solutions Power to Hydrogen (P2H) is one of the most appealing options. However despite the potential many obstacles currently hinder the development of the P2H market. This article aims to identify and analyse existing barriers to the introduction of P2H technologies that use hydrogen. The holistic approach used which was based on a literature survey identified obstacles and possible strategies for overcoming them. The research conducted presents an original research contribution at the level of hydrogen strategies considered in leading countries around the world. The research findings identified unresolved regulatory issues and sources of uncertainty in the armed forces. There is a lack of knowledge in the armed forces of some countries about the process of producing hydrogen energy and its benefits which raises concerns about the consistency of its exploitation. Negative attitudes towards hydrogen fuel energy can be a significant barrier to its deployment in the armed forces. Possible approaches and solutions have also been proposed to eliminate obstacles and to support decision makers in defining and implementing a strategy for hydrogen as a clean energy carrier. There are decisive and unresolved obstacles to its deployment not only in the armed forces

Process Integration of Green Hydrogen: Decarbonization of Chemical Industries
Sep 2020
Publication
Integrated water electrolysis is a core principle of new process configurations for decarbonized heavy industries. Water electrolysis generates H2 and O2 and involves an exchange of thermal energy. In this manuscript we investigate specific traditional heavy industrial processes that have previously been performed in nitrogen-rich air environments. We show that the individual process streams may be holistically integrated to establish new decarbonized industrial processes. In new process configurations CO2 capture is facilitated by avoiding inert gases in reactant streams. The primary energy required to drive electrolysis may be obtained from emerging renewable power sources (wind solar etc.) which have enjoyed substantial industrial development and cost reductions over the last decade. The new industrial designs uniquely harmonize the intermittency of renewable energy allowing chemical energy storage. We show that fully integrated electrolysis promotes the viability of decarbonized industrial processes. Specifically new process designs uniquely exploit intermittent renewable energy for CO2 conversion enabling thermal integration H2 and O2 utilization and sub-process harmonization for economic feasibility. The new designs are increasingly viable for decarbonizing ferric iron reduction municipal waste incineration biomass gasification fermentation pulp production biogas upgrading and calcination and are an essential step forward in reducing anthropogenic CO2 emissions.
Advanced Hydrogen Production through Methane Cracking: A Review
Jul 2015
Publication
Hydrogen is widely produced and used for our day-to-day needs. It has also the potential to be used as fuel for industry or can be used as an energy carrier for stationary power. Hydrogen can be produced by different processes like from fossil fuels (Steam methane reforming coal gasification cracking of natural gas); renewable resources (electrolysis wind etc.); nuclear energy (thermochemical water splitting). In this paper few processes have been discussed briefly. Cracking of methane has been given special emphasis in this review for production of hydrogen. There are mainly two types of cracking non-catalytic and catalytic. Catalytic cracking of methane is governed mainly by finding a suitable catalyst; its generation deactivation activation and filament formation for the adsorption of carbon particles (deposited on metal surface); study of metallic support which helps in finding active sites of the catalyst for the reaction to proceed easily. Non-catalytic cracking of methane is mainly based on thermal cracking. Moreover several thermal cracking processes with their reactor configurations have been discussed.

Feb 2017
Publication
Electrifying transportation is a promising approach to alleviate climate change issues arising from increased emissions. This study examines a system for the production of hydrogen using renewable energy sources as well as its use in buses. The electricity requirements for the production of hydrogen through the electrolysis of water are covered by renewable energy sources. Fuel cells are being used to utilize hydrogen to power the bus. Exergy analysis for the system is carried out. Based on a steady-state model of the processes exergy efficiencies are calculated for all subsystems. The subsystems with the highest proportion of irreversibility are identified and compared. It is shown that PV panel has exergetic efficiency of 12.74% wind turbine of 45% electrolysis of 67% and fuel cells of 40%.
Electrolyzer Performance Analysis of an Integrated Hydrogen Power System for Greenhouse Heating. A Case Study
Jul 2016
Publication
A greenhouse containing an integrated system of photovoltaic panels a water electrolyzer fuel cells and a geothermal heat pump was set up to investigate suitable solutions for a power system based on solar energy and hydrogen feeding a self-sufficient geothermal-heated greenhouse. The electricity produced by the photovoltaic source supplies the electrolyzer; the manufactured hydrogen gas is held in a pressure tank. In these systems the electrolyzer is a crucial component; the technical challenge is to make it work regularly despite the irregularity of the solar source. The focus of this paper is to study the performance and the real energy efficiency of the electrolyzer analyzing its operational data collected under different operating conditions affected by the changeable solar radiant energy characterizing the site where the experimental plant was located. The analysis of the measured values allowed evaluation of its suitability for the agricultural requirements such as greenhouse heating. On the strength of the obtained result a new layout of the battery bank has been designed and exemplified to improve the performance of the electrolyzer. The evaluations resulting from this case study may have a genuine value therefore assisting in further studies to better understand these devices and their associated technologies.
Roadmap to Decarbonising European Shipping
Nov 2018
Publication
Shipping is one of the largest greenhouse gas (GHG) emitting sectors of the global economy responsible for around 1 Gt of CO2eq every year. If shipping were a country it would be the 6th biggest GHG emitter. EU related shipping is responsible for about 1/5 of global ship GHG emissions emitting on average 200 Mt/year. This report assesses potential technology pathways for decarbonising EU related shipping through a shift to zero carbon technologies and the impact such a move could have on renewable electricity demand in Europe. It also identifies key policy and sustainability issues that should be considered when analysing and supporting different technology options to decarbonise the maritime sector. The basis of the study is outbound journeys under the geographical scope of the EU ship MRV Regulation.
We have not tried to quantify the emissions reductions that specific regulatory measures to be introduced at the IMO or EU level might contribute towards decarbonisation by 2050 because there are too many uncertainties. We have taken a more limited first approach and investigated how zero carbon propulsion pathways that currently seem feasible to decarbonise shipping would likely affect the future EU renewable energy supply needs.
It is now generally accepted that ship design efficiency requirements while potentially having an important impact on future emissions growth will fall well short of what is needed. Further operational efficiency measures such as capping operational speed will be important to immediately peak energy consumption and emissions but will be insufficient to decarbonise the sector or reduce its growing energy needs. In this context this study assumes that with all the likely immediate measures adopted energy demand for EU related shipping will still grow by 50% by 2050 over 2010 levels. This is within the range of the 20 -1 20% global BAU maritime energy demand growth estimate.
The decarbonisation of shipping will require changes in on -board energy storage and use and the necessary accompanying bunkering infrastructure. This study identifies the technology options for zero emission propulsion that based on current know-how are likely to be adopted. It is not exhaustive nor prescriptive because the ultimate pathways will likely depend on both the requirements of the shipping industry in terms of cost efficiency and safety and on the future renewable electricity sources that the shipping sect or will need to compete for.
Literature is nascent on the different techno-economic options likely to be available to decarbonise shipping and individual ships 4 but almost completely lacking on the possible impacts of maritime decarbonisation on the broader energy system(s). Understanding these impacts is nevertheless essential because it will influence financial and economic decision making by the EU and member states including those related to investment in future renewable energy supplies and new ship bunkering infrastructure. With this in mind the report aims to provide a preliminary first answer to the following question: Under different zero emission technology pathways how much additional renewable electricity would be needed to cater for the needs of EU related shipping in 2050?

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.
Power-to-Steel: Reducing CO2 through the Integration of Renewable Energy and Hydrogen into the German Steel Industry
Apr 2017
Publication
This paper analyses some possible means by which renewable power could be integrated into the steel manufacturing process with techniques such as blast furnace gas recirculation (BF-GR) furnaces that utilize carbon capture a higher share of electrical arc furnaces (EAFs) and the use of direct reduced iron with hydrogen as reduction agent (H-DR). It is demonstrated that these processes could lead to less dependence on—and ultimately complete independence from—coal. This opens the possibility of providing the steel industry with power and heat by coupling to renewable power generation (sector coupling). In this context it is shown using the example of Germany that with these technologies reductions of 47–95% of CO2 emissions against 1990 levels and 27–95% of primary energy demand against 2008 can be achieved through the integration of 12–274 TWh of renewable electrical power into the steel industry. Thereby a substantial contribution to reducing CO2 emissions and fuel demand could be made (although it would fall short of realizing the German government’s target of a 50% reduction in power consumption by 2050).
Study of the Permeation Flowrate of an Innovative Way to Store Hydrogen in Vehicles
Oct 2021
Publication
With the global warming of the planet new forms of energy are being sought as an alternative to fossil fuels. Currently hydrogen (H2) is seen as a strong alternative for fueling vehicles. However the major challenge in the use of H2 arises from its physical properties. An earlier study was conducted on the storage of H2 used as fuel in road vehicles powered by spark ignition engines or stacks of fuel cells stored under high pressure inside small spheres randomly packed in an envelope tank. Additionally the study evaluated the performance of this new storage system and compared it with other storage systems already applied by automakers in their vehicles. The current study aims to evaluate the H2 leaks from the same storage system when inserted in any road vehicle parked in conventional garages and to show the compliance of these leaks with European Standards provided that an appropriate choice of materials is made. The system’s compliance with safety standards was proved. Regarding the materials of each component of the storage system the best option from the pool of materials chosen consists of aluminum for the liner of the spheres and the envelope tank CFEP for the structural layer of the spheres and Si for the microchip.
Hydrogen Refuelling Reference Station Lot Size Analysis for Urban Sites
Mar 2020
Publication
Hydrogen Fuelling Infrastructure Research and Station Technology (H2FIRST) is a project initiated by the DOE in 2015 and executed by Sandia National Laboratories and the National Renewable Energy Laboratory to address R&D barriers to the deployment of hydrogen fuelling infrastructure. One key barrier to the deployment of fuelling stations is the land area they require (i.e. ""footprint""). Space is particularly a constraint in dense urban areas where hydrogen demand is high but space for fuelling stations is limited. This work presents current fire code requirements that inform station footprint then identifies and quantifies opportunities to reduce footprint without altering the safety profile of fuelling stations. Opportunities analyzed include potential new methods of hydrogen delivery as well as alternative placements of station technologies (i.e. rooftop/underground fuel storage). As interest in heavy-duty fuelling stations and other markets for hydrogen grows this study can inform techniques to reduce the footprint of heavy-duty stations as well.
This work characterizes generic designs for stations with a capacity of 600 kg/day hydrogen dispensed and 4 dispenser hoses. Three base case designs (delivered gas delivered liquid and on-site electrolysis production) have been modified in 5 different ways to study the impacts of recently released fire code changes colocation with gasoline refuelling alternate delivery assumptions underground storage of hydrogen and rooftop storage of hydrogen resulting in a total of 32 different station designs. The footprints of the base case stations range from 13000 to 21000 ft2.
A significant focus of this study is the NFPA 2 requirements especially the prescribed setback distances for bulk gaseous or liquid hydrogen storage. While the prescribed distances are large in some cases these setback distances are found to have a nuanced impact on station lot size; considerations of the delivery truck path traffic flow parking and convenience store location are also important. Station designs that utilize underground and rooftop storage can reduce footprint but may not be practical or economical. For example burying hydrogen storage tanks underground can reduce footprint but the cost savings they enable depend on the cost of burial and the cost land. Siting and economic analysis of station lot sizes illustrate the benefit of smaller station footprints in the flexibility and cost savings they can provide. This study can be used as a reference that provides examples of the key design differences that fuelling stations can incorporate the approximate sizes of generic station lots and considerations that might be unique to particular designs.

Hydrogen from Natural Gas – The Key to Deep Decarbonisation
Jul 2019
Publication
This Discussion Paper was commissioned by Zukunft ERDGAS to contribute to the debate concerning the deep decarbonisation of the European energy sector required to meet the Paris Agreement targets. Previous discussion papers have put forward decarbonisation pathways that rely heavily on ‘All-Electric’ solutions. These depend predominantly on renewable electricity to deliver decarbonisation of all sectors. This paper offers an alternative to an ‘All-Electric’ solution by building an alternative pathway that allows the inclusion of gas based technologies alongside the ‘All-Electric’ pathway technologies. The new pathway demonstrates that hydrogen from natural gas can be an essential complement to renewable electricity. The pathway also considers the benefits of utilising methane pyrolysis technology in Europe to produce zero carbon hydrogen.

A Roadmap for Financing Hydrogen Refueling Networks – Creating Prerequisites for H2-based Mobility
Sep 2014
Publication
Fuel cell electric vehicles (FCEVs) are zero tailpipe emission vehicles. Their large-scale deployment is expected to play a major role in the de-carbonization of transportation in the European Union (EU) and is therefore an important policy element at EU and Member State level.<br/>For FCEVs to be introduced to the market a network of hydrogen refuelling stations (HRS) first has to exist. From a technological point of view FCEVs are ready for serial production already: Hyundaiand Toyota plan to introduce FCEVs into key markets from 2015 and Daimler Ford and Nissan plan to launch mass-market FCEVs in 2017.<br/>At the moment raising funds for building the hydrogen refuelling infrastructure appears to be challenging.<br/>This study explores options for financing the HRS rollout which facilitate the involvement of private lenders and investors. It presents a number of different financing options involving public-sector bank loans funding from private-sector strategic equity investors commercial bank loans private equity and funding from infrastructure investors. The options outline the various requirements forn accessing these sources of funding with regard to project structure incentives and risk mitigation. The financing options were developed on the basis of discussions with stakeholders in the HRS rollout from industry and with financiers.<br/>This study was prepared by Roland Berger in close contact with European Investment banks and a series of private banks.<br/>This study explores in details the business cases for HRS in Germany and UK. The conclusion can be easily extrapolate to other countries.

Leakage-type-based Analysis of Accidents Involving Hydrogen Fueling Stations in Japan and USA
Aug 2016
Publication
To identify the safety issues associated with hydrogen fuelling stations incidents at such stations in Japan and the USA were analyzed considering the regulations in these countries. Leakage due to the damage and fracture of main bodies of apparatuses and pipes in Japan and the USA is mainly caused by design error that is poorly planned fatigue. Considering the present incidents in these countries adequate consideration of the usage environment in the design is very important. Leakage from flanges valves and seals in Japan is mainly caused by screw joints. If welded joints are to be used in hydrogen fuelling stations in Japan strength data for welded parts should be obtained and pipe thicknesses should be reduced. Leakage due to other factors e.g. external impact in Japan and the USA is mainly caused by human error. To realize self-serviced hydrogen fuelling stations safety measures should be developed to prevent human error by fuel cell vehicle users.
How Long Will Combustion Vehicles Be Used? Polish Transport Sector on the Pathway to Climate Neutrality
Nov 2021
Publication
Transformation of road transport sector through replacing of internal combustion vehicles with zero-emission technologies is among key challenges to achievement of climate neutrality by 2050. In a constantly developing economy the demand for transport services increases to ensure continuity in the supply chain and passenger mobility. Deployment of electric technologies in the road transport sector involves both businesses and households its pace depends on the technological development of zero-emission vehicles presence of necessary infrastructure and regulations on emission standards for new vehicles entering the market. Thus this study attempts to estimate how long combustion vehicles will be in use and what the state of the fleet will be in 2050. For obtainment of results the TR3E partial equilibrium model was used. The study simulates the future fleet structure in passenger and freight transport. The results obtained for Poland for the climate neutrality (NEU) scenario show that in 2050 the share of vehicles using fossil fuels will be ca. 30% in both road passenger and freight transport. The consequence of shifts in the structure of the fleet is the reduction of CO2 emissions ca. 80% by 2050 and increase of the transport demand for electricity and hydrogen.
