Transport is one of the key sectors of the European economy. However the intensive development of transport caused negative effects in the form of an increase in the emission of harmful substances. The particularly dramatic situation took place in the V4 countries. This made it necessary to implement solutions reducing emissions in transport including passenger transport. Such activities can be implemented in the field of implementation of low-emission and zero-emission vehicles for use. That is why the European Union and the governments of the Visegrad Group countries have developed numerous recommendations communications laws and strategies that order carriers to implement low- and zero-emission mobility. Therefore transport organizers and communication operators faced the choice of the type of buses. From an economic point of view each entrepreneur is guided by the economic efficiency of the vehicles used. Hence the main aim of the article was to conduct an economic evaluation of the operational efficiency of ecological vehicles. As more than 70% of vehicles in use in the European Union are still diesel driven the economic efficiency assessment was also made for vehicles with traditional diesel drive. To conduct the research the method of calculating the total cost of ownership of vehicles in operation was used. As a result of the research it was found that electric buses are the cheapest in the entire period of use (15 years) and then those powered by CNG. On the other hand the cost of using hydrogen buses is the highest. This is due to the high purchase prices of these vehicles. However the EU as well as the governments of individual countries support enterprises and communication operators by offering them financing for investments. The impact of the forecasted fuel and energy prices and the planned inflation on operating costs was also examined. In this case the analyses showed that the forecasted changes in fuel and energy prices as well as the expected inflation will significantly affect the costs of vehicle operation and the economic efficiency of using various types of drives. These changes will have a positive impact on the implementation of zero-emission vehicles into exploitation. Based on the analyses it was found that in 2035 hydrogen buses will have the lowest operating costs.

This report presents the findings of the initial gap analysis and technical review of IGEM/SR/25 undertaken as a collaborative effort between HSE and DNV GL. The review is intended to help understand the steps which would be involved in updating the standard to include data appropriate for installations using H2 or an H2/NG blend. Furthermore the report highlights where additional research and updated data applicable to H2 installations is needed to enable development of an H2-specific supplement to the standard.<br/>A review of alternative approaches for area classification is presented. This review is aimed at determining whether existing standards or guidance provide methodologies which could be used as an alternative to IGEM/SR/25 for area classification of systems using either H2 or H2/NG blends. The review covers IGEM/SR/25 IGE/SR/23 EI15 BCGA guidance BS EN 60079:10:1 (including Quadvent) NFPA 497 API RP 505 and EIGA Doc. 121/14. Some of these are general like the British Standard BS EN 60079-10-1:2015 while others are industry specific like IGEM/SR/25 and EI15.<br/>Consideration is given to the methodology that each area classification approach presents for establishing the zone and zone size with particular focus on how factors such as ventilation and gas buoyancy are accounted for in the methods. The findings of the review indicate that none of the alternative approaches evaluated in the study provide an approach that is suitable for the gas industry for the area classification of gas network installations involving H2 or an H2/NG blend.

On this weeks episode the team discuss hydrogen for aviation with ZeroAvia. Val launched ZeroAvia to provide a genuinely zero emission flight proposition with two aircraft currently undergoing trials in California and the UK. The company is due to complete a 300 mile flight of its six seater aircraft from the Orkney islands to the Scottish mainland this summer 2020 with plans for twenty seat planes flying regional routes as early as 20205. On the show we discuss why Val set up ZeroAvia how the proposition stacks up against conventional alternatives infrastructure and plans for the future. All this and more on the show!

Hydrogen energy utilization is expected due to its environmental and energy efficiencies. However many issues remain to be solved in the social implementation of hydrogen energy through water electrolysis. This analyzes and compares the energy consumption and GHG emissions of fossil fuel-derived hydrogen and gasoline energy systems over their entire life cycle. The results demonstrate that for similar vehicle weights the hydrogen energy system consumes 1.8 MJ/km less energy and emits 0.15 kg-CO 2 eq./km fewer GHG emissions than those of the gasoline energy system. Hydrogen derived from fossil fuels may contribute to future energy systems due to its stable energy supply and economic efficiency. Lowering the power source carbon content also improved the environmental and energy efficiencies of hydrogen energy derived from fossil fuels.

The aim of this paper is to analyze the factors affecting hydrogen and Carbon Capture and Storage Technologies (“CCS”) policies taking into consideration Fossil Fuel Consumption Oil Reserves the Debt/GDP Ratio the Trilemma Index and other variables with respect to OECD countries. STATA 17 was used for the analysis. The results confirm the hypothesis that countries with high fossil fuel consumption and oil reserves are investing in blue hydrogen and CCS towards a “zero-carbon-emission” perspective. Moreover countries with a good Debt/GDP ratio act most favorably to green policies by raising their Public Debt because Foreign Direct Investments are negatively correlated with those kinds of policies. Future research should exploit Green Finance policy decision criteria on green and blue hydrogen.

In order to maximise European national and regional research and innovation potential the European Union is investing in these fields through different funding mechanisms such as the ESIF or H2020 programme. This investment plan is part of the European 2020 strategy where the concept of Smart Specialisation is also included.<br/>Smart Specialisation is an innovation policy concept designed to promote the efficient and effective use of public investment in regional innovation in order to achieve economic growth. The Smart Specialisation Platform was created to support this concept by assisting regions and Member States in developing implementing and reviewing their research and innovation Smart Specialisation strategies.<br/>The Smart Specialisation Platform comprises several thematic platforms. The thematic Smart Specialisation Platform on energy (S3PEnergy) is a joint initiative of three European Commission services: DG REGIO DG ENER and the Joint Research Centre (JRC). The main objective of the S3PEnergy is to support the optimal and effective uptake of the Cohesion Policy funds for energy and to better align energy innovation activities at national local and regional level through the identification of the technologies and innovative solutions that support in the most cost-effective way the EU energy policy priorities.<br/>In the particular case of hydrogen technologies the activities of the platform are mainly focused on supporting the new Fuel Cells and Hydrogen Joint Undertaking (FCH JU) initiative involving regions and cities. To date more than 80 European cities and regions have committed to participate in this initiative through the signature of a Memorandum of Understanding and more participants are expected to join. S3PEnergy is helping in the identification of potential combination of H2020 funding (provided through FCH JU) and ESIF.<br/>To identify potential synergies among these two funding sources a mapping of the different ESIF opportunities has been performed. In order to map these opportunities Operational Programmes (OPs) and research and innovation strategies for Smart Specialisation (RIS3) of the different European regions and Member States were analysed. The results of this mapping and analysis are presented in this paper."

The HyDeploy project [1] has undertaken an extensive research programme to assess safety and performance of the existing UK gas appliances population fueled with natural gas / hydrogen admixtures (hydrogen blended gas). The first stage of this work [2] focused on well maintained and normally functioning appliances. This work demonstrated that unmodified gas appliances can operate safely with hydrogen blended gas (up to 20 vol% hydrogen) and the key hazard areas of carbon monoxide (CO) production light back and flame out and the operation of flame failure devices are unaffected. It is widely recognized that due to aging and variable degrees of maintenance that the combustion performance of a gas appliance will depreciate over time. In extreme cases this can lead to situations where high levels of CO may be released back into the dwelling resulting in CO poisoning to the occupants. To obtain a universal appreciation of the effect of hydrogen addition on the safety and performance of all gas appliances operation under sub optimal conditions is required and therefore it is important that the operation of malfunctioning appliances fuelled with hydrogen blended gas is assessed. A review of failure modes identified six key scenarios where the composition of the fuel gas may lead to changes in safety performance - these primarily related to the resulting composition of the flue gas but also included delayed ignition. Gas appliance faults that will increase the CO production were tested through a series of experiments to simulate fault conditions and assess the effect of hydrogen blended gas. The fault modes examined included linting flame chilling incorrect appliance set up and modification of gas valve operation. The programme utilized six different appliances tested with three methane-hydrogen fuel blends (containing 0 20 and 28.4 vol% hydrogen). In all cases the switch to hydrogen blended gas reduced CO production. The change in CO production when using hydrogen blended gas is a consequence of a decrease in the theoretical air requirement to achieve complete combustion. In some cases the amount of CO produced was identical to the nonfault baseline performance on methane thereby fully mitigating the consequence of the malfunction. In the case of very high CO production a 90% reduction was recorded when using 20 vol% hydrogen blended gas. In situations such as non-optimal boiler set up the addition of hydrogen to the gas supply would prevent the production of high levels of CO. The findings here together with the results from HyDeploy 1 [2] indicate that the safety and performance of unmodified existing UK gas appliances are not detrimentally affected when using hydrogen blended gas. Furthermore the addition of hydrogen to the fuel gas has been shown to reduce CO production under fault conditions therefore the introduction of hydrogen into the gas network may serve to mitigate the hazard posed by existing faulty appliances that are producing elevated levels of CO.

The development of public transport systems is related to the implementation of modern and low-carbon vehicles. Over the last several years there has been a clear progress in this field. The number of electric buses has increased and the first solutions in the area of hydrogen fuel cells have been implemented. Unfortunately the implementation of these technologies is connected with significant financial expenditure. The goal of the article is the analysis of effectiveness of financial investment consisting in the purchase of 30 new public transport buses (together with the necessary infrastructure–charging stations). The analysis has been performed using the NPV method for the period of 10 years. Discount rate was determined on 4% as recommended by the European Commission for this type of project. It is based on the case study of the investment project carried out by Metropolis GZM in Poland. The article determines and compares the efficiency ratios for three investment options-purchase of diesel-powered battery-powered and hydrogen fuel-cell electric vehicles. The results of the analysis indicate that the currently high costs of vehicle purchase and charging infrastructure are a significant barrier for the implementation of battery-powered and hydrogen fuel-cell buses. In order to meet the transport policy goals related to the exchange of traditional bus stock to more eco-friendly vehicles it is necessary to involve public funds for the purpose of financing the investment activities.

Hydrogen is fast becoming a new international “super fuel” to accelerate global climate change ambitions. This paper has two inter-weaving themes. Contextually it focuses on the potential impact of the EU’s new Carbon Border Adjustment Mechanism (CBAM) on fossil fuel-generated as opposed to green hydrogen imports. The CBAM as a transnational carbon adjustment mechanism has the potential to impact international trade in energy. It seeks both a level playing field between imports and EU internal markets (subject to ambitious EU climate change policies) and to encourage emissions reduction laggards through its “carbon diplomacy”. Countries without a price on carbon will be charged for embodied carbon in their supply chains when they export to the EU. Empirically we focus on two hydrogen export/import case studies: Australia as a non-EU state with ambitions to export hydrogen and Germany as an EU Member State reliant on energy imports. Energy security is central to energy trade debates but needs to be conceptualized beyond supply and demand economics to include geopolitics just transitions and the impacts of border carbon taxes and EU carbon diplomacy. Accordingly we apply and further develop a seven-dimension energy security-justice framework to the examples of brown blue and green hydrogen export/import hydrogen operations with varying carbon-intensity supply chains in Australia and Germany. Applying the framework we identify potential impact—risks and opportunities—associated with identified brown blue and green hydrogen export/import projects in the two countries. This research contributes to the emerging fields of international hydrogen trade supply chains and international carbon diplomacy and develops a potentially useful seven-dimension energy security-justice framework for energy researchers and policy analysts.

The document provides information on safety planning monitoring and reporting for the concerned hydrogen and fuel cell projects and programmes in Europe. It does not replace or contradict existing regulations which prevails under all circumstances. Neither is it meant to conflict with relevant international or national standards or to replace existing company safety policies codes and procedures. Instead this guidance document aims to assist in identifying minimum safety requirements hazards and associated risks and in generating a quality safety plan that will serve as an assisting guide for the inherently safer conduct of all work related to the development and operation of hydrogen and fuel cell systems and infrastructure. A safety plan should be revisited periodically as part of an overall effort to pay continuous and priority attention to the associated safety aspects and to account for all modifications of the considered system and its operations. Potential hazards failure mechanisms and related incidents associated with any work process or system should always be identified analysed reported (recorded in relevant knowledge databases e.g. HIAD 2.0 or HELLEN handbooks papers etc.) and eliminated or mitigated as part of sound safety planning and comprehensive hydrogen safety engineering which extends beyond the recommendations of this document. All relevant objects or aspects that may be adversely affected by a failure should be considered including low frequency high consequences events. So the general protection objective is to exclude or at least minimise potential hazards and associated risks to prevent impacts on the following:

• People. Hazards that pose a risk of injury or loss of life to people must be identified and eliminated or mitigated. A complete safety assessment considers not only those personnel who are directly involved in the work but also others who are at risk due to these hazards.
• Property. Damage to or loss of equipment or facilities must be prevented or minimised. Damage to equipment can be both the cause of incidents and the result of incidents. An equipment failure can result in collateral damage to nearby equipment and property which can then trigger additional equipment failures or even lead to additional hazards and risks e.g. through the domino effect. Effective safety planning monitoring and reporting considers and minimises serious risk of equipment and property damage.
• Environment. Damage to the environment must be prevented. Any aspect of a natural or the built environment which can be harmed due to a hydrogen system or infrastructure failure should be identified and analysed. A qualification of the failure modes resulting in environmental damage must be considered.
