Hydrogen Policy, Safety & Standards (11)


H2 Safety P.1. 09 Jan 2025, ScienceDiirect, Keep it local and safe: Which system of green hydrogen production in Germany is accepted by citizens?, "Our study aims to identify significant factors influencing the German population's acceptance of green hydrogen production within various acceptance groups with differing preferences for future green hydrogen production systems. We conducted an online survey (n=1,203) in Germany in 2022/2023, incorporating a choice experiment."
H2 Safety P.2. 16 Dec 2024, ScienceDiirect, Recent advances in combustion science related to hydrogen safety, "This review covers laboratory, medium and large-scale experiments, as well as theoretical analysis and numerical simulation results. While highlights are provided at the end of each section, the paper closes with some concluding remarks highlighting the achievements and key knowledge gaps."
AU Future Gas Strategy P.3. 25 Jun 2024, Australian Federal Government, Future Gas Strategy, "Two of six principles include: Australia is, and will remain, a reliable trading partner for energy, including Liquefied Natural Gas and low emission gases. Gas must remain affordable for Australian users throughout the transition to net zero." Australia's Future Gas Strategy submission comparison: Ernst & Young vs. GreenPeace Australia
H2 Safety H2 P.4. 08 Jun 2024, MDPI, Artificial Intelligence-Driven Innovations in Hydrogen Safety, "Here, a comprehensive exploration of recent advancements in hydrogen safety, particularly the application of AI methodologies in evaluating potential safety scenarios, and the design of safety measures is considered. Against this backdrop, the integration of AI methodologies emerges as a transformative paradigm in augmenting H2 safety measures."
H2 Standards Australia P.5. 13 May 2024, Standards Australia, AU Hydrogen Standards, ME-093 Hydrogen Technologies Strategic Work Plan (PDF) summarises the work of Standards Australia’s ME-093, H2 Technologies committee & highlights its future activities."
Sandia National Laboratories P.6. 07 May 2024, Sandia National Laboratories, US Hydrogen Safety, Codes, and Standards, Sandia’s H2 safety, codes, and standards research program develops the technical data and scientific understanding necessary to offer science-based improvements to the codes & standards that define the safe use of H2. These codes and standards are critical for the broader use and deployment of H2."
CSIRO HyStandards H2 P.7. 01 Feb 2024, HyStandards has been developed by Standards Australia + CSIRO to provide industry, government & community a means of identifying relevant H2 standards through a visual representation of H2 facility scenarios:
🔴 Electrolyser hydrogen production
🔴 Gaseous hydrogen transport by road
🔴 Hydrogen transport by pipeline
🔴 Blended hydrogen transport by pipeline
🔴 Hydrogen refuelling
MDPI Safety Assessment H2 Jet Fire P.8. 12 Jan 2023, MDPI, Safety Assessment of H2 Jet Fire Scenarios within Semi-Confined Spaces, "This study applied computational fluid dynamics simulations in conjunction with probabilistic calculation methods to determine the associated thermal risk of a H2 jet fire in a tunnel & its dependency on scenarios with different tunnel slopes, longitudinal & transverse ventilation velocities, & fire positions."
H2 Safety Policy P.9. 10 Jul 2020, Australian Hydrogen Council, AU Hydrogen: Policy & Regulation,
"Standards cover:
Safety aspects of H2 generators;
Performance of stationary H2 generators for residential, commercial & industrial applications;
Quality of hydrogen fuel for vehicular & stationary applications;
Construction, safety & performance of systems to produce H2 by the electrolysis of H20;
Design & safety features of systems to purify H2 to meet quality standards;
Design, construction & testing of portable H2 containers;
Design, manufacture & testing of tanks for H2-powered vehicles;
Safety & testing of high pressure valves used in refuelling stations for H2 powered vehicles."
