This edition of the Global Gas Report covers two very turbulent years in the global gas industry and the wider global energy markets. The Covid-19 pandemic lockdowns with a brief period of excess supply and low prices gave way to tight energy markets extreme price volatility and a compounding geopolitical challenge to energy security. At the time of writing the ongoing Russia-Ukraine conflict has been affecting the flows of gas and has put Europe on a quest to diversify its energy and gas supply that is now opening a new paradigm in the energy industry. This report comes at a time when the situation for global commodity and gas markets is in a state of rapid change and the strategic path forwards for the gas industry and energy policy-makers is continually developing. One thing is clear this is a critical and decisive moment for the gas industry. How it navigates the way through this crisis and charts a path forward will shape its long-term success and the role that it will play in the energy transition and beyond. This is the moment for the gas industry to demonstrate that gas can deliver a sustainable and secure energy future for all and that natural gas and a portfolio of decarbonized low- and zero-carbon gases are key to an achievable energy transition. This year’s report assesses key gas market trends from 2020 and 2021 including Covid-19 outcomes tightness of supply price volatility investments and the upward reversal in the global emissions trend. It then turns to the main topic on the global energy agenda – security – and considers key variables impacting it from industry and policy perspectives as well as considering possible paths to reinforce it. Finally the report looks at the main decarbonization pathways for gas supply as they progressively develop to make gas itself a low or zero-carbon fuel for the future. This report seeks to deliver insights about the global gas sector and to inform its stakeholders partners and importantly global decision-makers about the state of play today and possibilities for the future. It concludes with key insights on how sustainability security and competitiveness can help to deliver a sustainable future in line with the goals of the Paris Agreement and the UN Sustainable Development Agenda.

The transportation and mobility sector is vast complex unwieldy and most excitingly an obvious area of focus for hydrogen fuel cell technology applications. Hydrogen FCEVs allow vehicles to run in a wide range of environments with zero tailpipe emissions and can do so without the need for extremely heavy battery cells and can be refueled in the same amount of time as a modern ICE vehicle. This makes hydrogen FCEVs an ideal fit for the heavy commercial transportation industry and is why Hyzon Motors has jumped at the opportunity to revolutionize the industry. The company has grabbed headlines all over the world with its ambitious plans for rolling out its trucks in the United States and other major markets. It has also made news with its recent announcement that the company is going public and has attracted significant investor interest. The EAH team is joined on this episode by Hyzon's CEO Craig Knight to talk about how the company is tackling some of the most significant challenges in decarbonizing transport and how it can make trucking a zero-emission operation.

Hydrogen has been attracting attention as a fuel in the transportation sector to achieve carbon neutrality. Hydrogen storage in liquid form is preferred in locomotives ships drones and aircraft because these require high power but have limited space. However liquid hydrogen must be in a cryogenic state wherein thermal insulation is a core problem. Inner materials including glass bubbles multi-layer insulation (MLI) high vacuum and vapor-cooled shields are used for thermal insulation. An analytic study is preferred and proceeds liquid hydrogen tanks due to safety regulations in each country. This study reviewed the relevant literature for thermodynamic modeling. The literature was divided into static dynamic and systematic studies. In summary the authors summarized the following future research needs: The optimal design of the structure including suspension baffle and insulation system can be studied to minimize the boil-off gas (BOG). A dynamic study of the pressure mass flow and vaporizer can be completed. The change of the components arrangement from the conventional diesel–electric locomotive is necessary.

Electromobility is a growing technology for land transport constituting an important element of the concept of sustainable economic development. The article presents selected research results concerning one of the segments of this market-vehicles powered by hydrogen fuel cells. The subject of the research was to gain extensive knowledge on the economic factors influencing the future purchasing decisions of the demand side in relation to this category of vehicles. The research was based on a numerical experiment. For this purpose a comparative analysis of purchase prices in relation to the TCO of the vehicle after 3–5 years of use was performed. The research included selected models that are powered by both conventional and alternative fuels. The use of this method will allow to assess the real costs associated with the hydrogen vehicle. The authors emphasize the important role of economic factors in the form of the TCO index for the development of this market. The experimental approach may be helpful in understanding the essence of economic relations that affect the development of the electro-mobility market and the market demand for hydrogen fuel cell-powered vehicles in Poland.

This paper investigates an integrated system where solar energy system (with 75MWp bifacial PV arrays) and nuclear power plant (with 2×10MWt HTR-10 type pebble bed reactors) are hybridized and integrated with a 72MWe capacity high-temperature solid oxide electrolysis (SOE) unit to produce hydrogen fresh water and electrical power. Bifacial PV plant is integrated to system for supplying electricity with a low LCOE and zero-carbon system. A Rankine cycle is integrated to generate power from the steam that generated from nuclear heat. According to the available irradiance; the steam is diverted between steam turbine and high-temperature electrolyzer for hydrogen and power generation. Multi-effect desalination unit is integrated to exploit the excess heat to generate fresh water. A system performance assessment is carried out by energy and exergy efficiencies thermodynamically. The bifacial PV plant is analyzed in six selected latitudes in order to assess the feasibility and applicability of the system. Numerous time-dependent analyses are carried out to study the effects of varying inputs such as solar radiation intensity. For 20MWt nuclear 75MWp solar capacity; hydrogen productions are found to be between 0.036 and 0.562kg/s. Among the Northern Hemisphere latitudes the peak daily hydrogen production rate is expected to reach 25.9 tons of hydrogen per day for the 75 °N case mostly with the influence of low temperature and high albedo. The pitch distance change is increased the hydrogen production rate by 28% between 3 m and 7 m tracker spacing. The overall system energy efficiency is obtained between 21.8% and 24.2% where the overall system exergy efficiency is found between 18.6% and 21.1% under dynamic conditions for the 45°N latitude case.

On this episode of EAH the team is joined by Tim Yeo Chairman of Powerhouse Energy to talk about the work they are doing in the waste-to-energy space and how they see the sector evolving in the coming years.

Direct containment heating (DCH) is one of the potential factors leading to early containment failure. DCH is closely related to safety analysis and containment performance evaluation of nuclear power plants. In this study a DCH prediction program was developed to analyze the DCH loads of containment vessel. The phenomenological model of debris dispersal metal oxidation reaction debris-atmospheric heat transfer and hydrogen jet burn was established. Code assessment was performed by comparing with several separate effect tests and integral effect tests. The comparison between the predicted results and experimental data shows that the program can predict the key parameters such as peak pressure temperature and hydrogen production in containment well and for most comparisons the relative errors can be maintained within 20%. Among them the prediction uncertainty of hydrogen production is slightly larger. The analysis shows that the main sources of the error are the difference of time scale and the oxidation of cavity debris.
