  Measurements of the viscosity of pure hydrogen and a binary (hydrogen + methane) mixture with a nominal composition 90 mol % hydrogen are presented. The measurements were conducted with a two-capillary viscometer relative to helium along three isotherms of (298.15, 323.15, and 348.15) K and at pressures of up to 18 MPa. Expanded relative combined uncertainties in viscosity range from (0.65 to 2.7) % (k = 2) for the hydrogen data, and from (0.91 to 3.2) % (k = 2) for the (hydrogen + methane) data. The viscosity data are compared to experimental literature data and viscosity correlations implemented in the NIST REFPROP v10.0 database. Good agreement between this work’s data, literature data, and the viscosity correlation was achieved for pure hydrogen. The (hydrogen + methane) mixture was compared to the Extended Corresponding States (ECS) model implemented in REFPROP v10.0. Relative deviations between the experimental data and the ECS model exceed the experimental uncertainty and were found to exhibit a positive trend with increasing density and a weakly pronounced negative trend with increasing temperature. No experimental literature data are available at overlapping state regions. Nonetheless, deviations to the ECS model imply reasonable consistency of this work’s data and literature data. In addition to experimental viscosities, experimental zero-density viscosity ratios of the fluids under investigation and helium are reported. Fairly good agreement within the experimental uncertainty of this work with a highly accurate literature value and a value obtained from accurate ab initio calculated data was achieved for hydrogen.

  As the world embarks on a transition towards a sustainable, carbon-neutral energy future, hydrogen has emerged as a promising alternative energy carrier. However, the safe handling and storage of hydrogen is a challenge due to its unique properties and associated hazards. In this work, a review of the state of the art on the availability and quality of data for quantitative risk analysis is performed. Gaps and needs in data collection are identified with the aim to understand what the challenges for the safe use of hydrogen are. To ensure and demonstrate the safe and reliable operation of hydrogen systems, it is crucial to understand their equipment classes, failure modes, and safety equipment performance. However, from the comprehensive review of the literature and existing industry practices, a significant lack of standardization in the definitions of these classes and modes is highlighted. This can lead to inconsistent data collection and interpretation, limiting the ability of researchers and practitioners to identify and mitigate safety risks. Additionally, the data available is incomprehensive and low-quality. The current gaps in data may stem from a variety of factors, including the novelty of some types of hydrogen equipment, proprietary concerns, and a lack of centralized data collection and sharing platforms. Several solutions are proposed for the identified gaps and needs for data collection of hydrogen systems. These include the development of universal definitions of hydrogen equipment classes and failure modes, the establishment of centralized data collection and sharing platforms, and the creation of detailed guidelines for the selection of safety equipment. This work is intended to inform future research and standards development efforts, thereby contributing to the safe and successful deployment of hydrogen energy systems. It emphasizes the importance of collaboration and data sharing between researchers, industry practitioners, regulators, and standardization bodies to overcome these challenges. In conclusion, the safe and effective deployment of hydrogen systems requires a rigorous and comprehensive approach to data collection, equipment classification, failure mode definition, and safety equipment selection. Addressing these gaps and needs will require concerted efforts from all stakeholders in the hydrogen community. KEYWORDS: Failure modes, Hydrogen, Equipment Classes, Safety Equipment, HIAD 2.0

  Europe has ambitious hydrogen-related goals. Strategies have been developed at both the union and individual country level to maximize the benefits of this clean energy source. Besides Europe, many countries globally have implemented their own strategies, ambitions, and programs to promote hydrogen development and use. Norway is uniquely positioned in this global context. It has abundant clean energy sources, substantial natural gas reserves, and is geographically close to Europe. These factors could boost hydrogen production and use. Furthermore, these factors could drive the development and application of the necessary technology, potentially positioning Norway as a global leader in the hydrogen landscape. Although the details of the economics and logistics are not clear yet, understanding them is crucial. The Hydorgen-i project aims to thoroughly investigate the hydrogen value chain, in Norway and also internationally. This examination will include both economic factors and social perspectives. This comprehensive understanding will help us develop effective strategies for the future. We will use the BROMo optimisation model, which focuses on logistics, to gain insights into localisation, transport, and investment aspects of the hydrogen value chain. Depending on prices, distances, and the availability of raw materials, BROMo could help determine Norway's optimal role in the future of hydrogen. For the second analysis, we use a macroeconomic model called SUMSNorway. This model operates on a national scale, analysing national industrial structures and determining how investments, imports, and production factors impact value chains. SUMSNorway helps us understand which industries will need more labor and likely education to enhance value creation. Although these models are from entirely different research areas, we have successfully combined their results in the past. We've used macroeconomic tables, like those in SUMS, to guide our optimisation models’ demand, supply, and industrial conversion parameters. We plan to use the results of the optimisation simulations to inform the macroeconomic models.

  Regulations for fuel usage in maritime traffic by MARPOL are setting global standards that aims at reducing air pollution, reducing carbon emissions, and increasing energy efficiency. However, in the event of an accidental acute spill, how does conventional fuel oils compare to green ammonia in terms of potential environmental impact? We explored this challenge by a combination of an experimental ecotoxicology and a modelling approach. First, we assessed the acute and sub-lethal toxicity of fuel oils and ammonia to Atlantic cod (Gadus morhua) embryos. Atlantic cod embryos were exposed for 4 days starting 3 days after hatch, and after exposure, the embryos were transferred to clean sea water until 3 days post hatch. Survival and hatching were monitored daily, and at the end of the experiment, larvae were imaged for assessing larvae morphometry and potential deformations. Second, we simulated acute spills of the fuels using the Dose-related Risk and Effects Assessment Model (DREAM) and the Oil Spill Contingency and Response model (OSCAR) to predict spreading and estimate the risk of toxicity to pelagic marine organisms. Ammonia caused acute toxicity to cod embryos; however, no indications of delayed toxicity were observed. No additional mortality was observed during the recovery period, and the surviving larvae displayed no deformations. Fish exposed to petrogenic fuel oils, however, displayed both acute toxicity as well as clear signs of deformations. DREAM and OSCAR simulations suggests that most of the ammonia reached the surface and evaporated, but some spreading of ammonia as ammonium generated a plume which displayed concentrations exceeding predicted no-effect concentrations (PNEC). Spills of marine gas oil, very low sulphur fuel oil and heavy fuel oil behaved differently. MGO, like ammonia, spread in the water column, however, substantial fractions also evaporated, biodegraded, surfaced, and reached shorelines. Most of the heavy fuel oil and very low sulphur fuel oil, however, ended up on the surface and were carried by waves and to shorelines, and very little of the mass ended up in the water column. The MGO had a lower PNEC than ammonia, so the total volumes of water containing concentrations exceeding the PNEC was higher for MGO than ammonia. For the VLSFO and HFO, insignificant volumes of water exceeded PNEC, due to the fate outcomes discussed above.

  The discussion surrounding the role of (renewable and/or low-carbon) hydrogen in the energy transition is far from over, opinions ranging virtually from ‘fanciful idea’ to ‘silver-bullet’. Irrespective of the outcome of such discussion, multiple projects are somewhere in design / pre-FEED stage, the issue ‘offtaking / offtaker’ emerging as a critical point. Here, the contract for sale and purchase of hydrogen (and derivatives) has become the centre of attention. The Association of International Energy Negotiators (AIEN), which holds a proven track record in developing model agreements for the oil and gas industry, launched in 2022 a ‘Hydrogen Taskforce’ to delve into contract standardization in the realm of hydrogen. During this webinar, an account of the work undertaken, next steps and some of the specific challenges encountered were given.

  The positrode is a critical component for proton ceramic steam electrolyzers and fuel cells for hydrogen and ammonia. It constitutes a major contribution to the over-potentials and hence losses in the whole cell, resulting from its limited solubility and diffusivity of protons, which is challenging to characterise and improve. We are introducing a PhD project that aims to establish theoretical frameworks and experimental methodology for measuring protonic conductivities in the bulk and on surfaces of positrode materials. The approaches to reach the goal comprise the use of defect chemistry and transport theory for protons conduction, with the implementation of physiochemical experiments to distinguish signals of protons among other defects and charge carriers and paths on those predominantly electronic conductors. The results will be used as input to other project participants who perform computer simulations and, on that basis, seek strategies for optimization and effects on electrodes in scaled-up cells.
