This article explores Type IV compressed hydrogen tanks, key for efficient hydrogen storage and transport in the energy transition. It examines their technical characteristics, including geometric design, materials for the liner and composite envelope, and manufacturing methods. Type IV tanks, combining a polymer liner with a composite enveloppe; offer safe, lightweight high-pressure hydrogen storage. The article addresses challenges and innovations, such as non-cylindrical tank development for better vehicle integration, and safety and performance standards. It highlights technological advancements and development efforts to boost hydrogen adoption as a sustainable energy source.
Hydrogen is considered a relevant energy carrier to reduce greenhouse gas emissions in the transport sector, especially for heavy duty and off-road applications. After briefly exploring the hydrogen industry and its production methods, the article focuses on the physico-chemical properties of hydrogen as a fuel, with a particular emphasis on its behavior during combustion. Then, these properties are analyzed for their impact on existing internal combustion engine technologies, leading to the establishment of a functional specification, that also integrates safety considerations. The main players in this field, along with their two technological approaches – retrofitting existing engines and specific development – are also presented.
The chemical storage of hydrogen in organic liquids (LOHC) is governed by two catalytic reactions: hydrogenation of the hydrogen-lean molecule and dehydrogenation of the hydrogen-rich molecule. The pairs of molecules are chosen to be storable and transportable over long periods and distances in standard infrastructures. This article provides an overview of the LOHC pairs, catalysts and reactors involved in implementing this technological solution, with a view to sizing the process. Energy efficiency, environmental and economic aspects are also analysed.
This article aims at reviewing electrodes manufacturing processes for alkaline water electrolysis. It introduces the most recent developments about alkaline electrolysers, and compares traditional processes (electrodeposition, hydrothermal synthesis) used to functionalise electrodes with the emerging process of metallic additive manufacturing (SLM 3D Printing, Selective Laser Melting). This process allows disruptive work on functionalisation and tailored shapes for electrodes. It also permits to design new non-conventional electrolysers.
This article describes how the emergence of a global hydrogen market risks upsetting the established order and trade relationships between countries. A new energy geography is taking shape with a few importing regions, while many potential exporters will compete. Some exporters want to replace their exports in fossil energy with hydrogen; others are aiming to become major players thanks to cheap renewable hydrogen exports. However, transporting hydrogen (or its derivatives) across long distances remains a major obstacle. Finally, the competition also takes place at the technological level, in particular on electrolysers.
Although in 2022 barely 1% of the hydrogen produced in the world come from green hydrogen, this situation is set to change in the years to come, particularly in Europe and France, thanks to the support of the public authorities. The emerging low-carbon hydrogen industry is gradually taking shape and new players are emerging, often from an increasingly rich network of SMEs. This article lists the European "green" hydrogen players, classified by typology, country, sector, business and by their role in the hydrogen value chain.
Hydrolysis reaction with metals is an efficient way for producing hydrogen on demand without using external energy source and without greenhouse gases emission. Thanks to its abundance and high reactivity with water, magnesium is a very interesting material for this application. The article presents the main characteristics of this green hydrogen production method. The preparation of reactants as well as reaction mechanisms are presented. Analysis methods used for the research of efficient materials are also discussed. Finally, application examples illustrate some of the opportunities offered by this technology.
The use of hydrogen as an energy carrier adds complexity to the value chain, due to the diversity of production methods, storage challenges, specific infrastructures and technological adaptations required for its use. This infographic details the different stages in the industry, from production to current and future applications.
Due to regulation requirements, gas purification has become essential for any industrialist using at least one gas in their production process. The PSA process is included in the currently used technologies of gas purification, each of them offering its own characteristics and performances. The determination of the design criteria of a PSA unit requires, amongst other factors, a sound knowledge of calculation parameters, the influence of pressure levels, design principles of absorbers and valve diagrams. To date, the PSA gas purification has clearly demonstrated its advantages, in terms of cost and specific separation energy.
