Dear Colleagues,
Hydrogen is a clean, promising and versatile energy carrier. Its use is rapidly growing in various fields, including energy production, mobility, building heating, industrial processes and the storage of excess electrical energy resulting from renewable energy sources.
Among the most important challenges related to the use of hydrogen as clean energy are storage and delivery. This call is specifically dedicated to the collection of research articles and literature reviews that address the technical barriers limiting the storage and transport of hydrogen in any form (pressurized gas, cryogenic liquid or solid fuel).
Contributions focused on the design and construction of fixed, vehicular and bulk storage vessels, with every type of material (i.e., metals, polymers, polymer composites and others) and design and optimization approaches (from the most traditional to the most advanced ones, such as those using artificial intelligence) are welcome. Studies focusing on the transportation of pure or blended hydrogen via, low- or high-pressure, onshore or offshore, pipelines, whatever their function (collection, transmission or distribution), including non-destructive methods for line monitoring, are also of interest.
Regarding materials, advanced investigations that take into consideration the problems related to the influence of hydrogen on their physical and transport properties (permeability, diffusivity and solubility of hydrogen, rapid decompression of gases), mechanical behavior in tension, compression and shear, fracture, fatigue and impact, even when pressure and temperature vary, will be taken into great consideration, as well as friction, viscoelasticity, corrosion, aging, structural damage (embrittlement, blistering), test methods, safety challenges of the working environment, sustainable development, circular economy and recycling.
Particular attention will be given to the development of devices of all types, such as valves, accumulators, compressor nozzles, pre-coolers and filters, as well as seals, which serve to regulate distribution and ensure the absence of leaks for fuel cell vehicles and hydrogen refueling stations.
Looking forward to your contributions.
