Jeremy Luterbacher, Songlan Sun, Stefania Bertella, Anastasiia Komarova
The present invention relates to a compound of the general formula (I), and (II)wherein one of R11 and R12 is hydrogen and the other is -CH2-R70, and one of R13 and R14 is hydrogen and the other is -CH2-R71, or wherein one of R11 and R12 is hydrogen and th ...
2024Large-cage occupation and quantum dynamics of hydrogen molecules in sII clathrate hydrates
Richard Gaal, Livia Eleonora Bove Kado, Umbertoluca Ranieri
Hydrogen clathrate hydrates are ice-like crystalline substances in which hydrogen molecules are trapped inside polyhedral cages formed by the water molecules. Small cages can host only a single H-2 molecule, while each large cage can be occupied by up to f ...
Aip Publishing2024Using Complex Hydrides for Hydrogen Storage and Direct Borohydride Fuel Cells for Electricity Production
Hydrogen storage and utilization are the technologies to achieve carbon-neutral energy systems with renewable energy sources. Among the various materials that have been investigated, complex hydrides are a material exhibiting high gravimetric hydrogen dens ...
EPFL2023Natural aging and vacancy trapping in Al-6xxx
William Curtin, Michele Ceriotti
Undesirable natural aging (NA) in Al-6xxx delays subsequent artificial aging (AA) but the size, composition, and evolution of clustering are challenging to measure. Here, atomistic details of early-stage clustering in Al-1% Mg-0.6%Si during NA are studied ...
Heidelberg2023Delayed Hydride Cracking in Irradiated and Unirradiated Zircaloy-2 Cladding
Zirconium alloys used in the nuclear industry are exposed to extreme conditions undergoing high levels of irradiation damage and corrosion. Zircaloy-2 is used as nuclear fuel cladding in boiling water reactors and for the encapsulation of the spallation ta ...
EPFL2022Economies of Scale in PEMEC and SOEC Manufacturing based on a Bottom-up Model
Under the scope of net zero emission, a large-scale deployment of renewable technologies, especially clean hydrogen technologies are required. Hydrogen is a clean fuel and an ideal energy carrier that can be used to store, move, and deliver energy. Nowaday ...
2022Optimization of the Hydrogen Network in an Oil Refinery
The stricter environmental and product quality regulations are pushing oil refineries to increase hydrotreatment and hydrocracking capacities to lower the sulfur contents in the products, thus leading to a higher demand for hydrogen. The efficient use of h ...
2022Multi-criteria optimization of a renewable hydrogen and freshwater production system using HDH desalination unit and thermoelectric generator
This article presents the exergoeconomic evaluation of a new geothermal-based integrated system, which produces hydrogen and freshwater. The proton exchange membrane electrolyzer (PEME) and humidifier-dehumidifier (HDH) units are responsible for hydrogen a ...
PERGAMON-ELSEVIER SCIENCE LTD2020Combined hydrogen storage - compression system for the filling of high pressure hydrogen tanks
Andreas Züttel, Noris André Gallandat
The present relates to a combined hydrogen storage-compression unit suitable for the filling of high-pressure (350 bar and beyond) hydrogen vessels. It comprises a containment vessel filled with a hydrogen storage alloy, a heating system, a cooling system ...
2020The role of atomistic simulations in probing hydrogen effects on plasticity and embrittlement in metals
Atomistic simulations are a powerful complement to experimental probes for understanding the nanoscale processes associated with the effects of hydrogen (H) on plasticity and fracture that are the underlying causes of hydrogen embrittlement (HE). Current e ...
