“…The low molecular weight of hydrogen gas, the lowest of any molecule, makes it extremely buoyant and liable to accumulate within enclosed spaces, and as such, even slow leaks represent a substantial safety hazard [33,34]. Many fires and explosions within hydrogen power plants have been reported, and this risk is set only to increase with the widespread deployment of hydrogen-based infrastructure [35]. There is also a substantial need within this infrastructure to accurately quantise high concentrations of hydrogen gas or to identify contaminant compounds within a mixture dominated by hydrogen gas.…”

The demand for green hydrogen as an energy carrier is projected to exceed 350 million tons per year by 2050, driven by the need for sustainable distribution and storage of energy generated from sources. Despite its potential, hydrogen production currently faces challenges related to cost efficiency, compliance, monitoring, and safety. This work proposes Hydrogen 4.0, a cyber–physical approach that leverages Industry 4.0 technologies—including smart sensing, analytics, and the Internet of Things (IoT)—to address these issues in hydrogen energy plants. Such an approach has the potential to enhance efficiency, safety, and compliance through real-time data analysis, predictive maintenance, and optimised resource allocation, ultimately facilitating the adoption of renewable green hydrogen. The following sections break down conventional hydrogen plants into functional blocks and discusses how Industry 4.0 technologies can be applied to each segment. The components, benefits, and application scenarios of Hydrogen 4.0 are discussed while how digitalisation technologies can contribute to the successful integration of sustainable energy solutions in the global energy sector is also addressed.

“…Building on collaborations initiated in Task 19, the project leads from PNNL and the European Commission's Joint Research Centre (JRC) shared the podium during a topical session on safety event databases [13,14] and also provided online demonstrations of their respective tools at the September 2011 International Conference on Hydrogen Safety (ICHS) in San Francisco. The JRC and the International Association for Hydrogen Safety are responsible for the Hydrogen Incident and Accident Database (https://odin.jrc.ec.europa.eu/ Hiad4/index.hiad) [15].…”

Computational fluid dynamics a b s t r a c t The International Energy Agency's Hydrogen Implementing Agreement (IEA HIA) was established in 1977 to pursue collaborative hydrogen research and development and information exchange among its member countries. Information and knowledge dissemination is a key aspect of the work within IEA HIA tasks, and case studies, technical reports and presentations/publications often result from the collaborative efforts. The work conducted in hydrogen safety under Task 31 and its predecessor, Task 19, can positively impact the objectives of national programs even in cases for which a specific task report is not published. The interactions within Task 31 illustrate how technology information and knowledge exchange among participating hydrogen safety experts serve the objectives intended by the IEA HIA.

“…Hydrogen storage and transportation are critical to the commercialization of hydrogen. , Currently, among the three mainstream hydrogen storage methods (storage in gaseous, liquid, and solid forms), the storage of high-pressure hydrogen (HPH) in the gaseous state is the most advantageous, − it has a simple equipment structure, high hydrogen charging speed, and high release speed. , Hydrogen can be transported by road, by sea, or through pipelines in gaseous, liquid, or metallic hydride form, the method of delivery depends on the relevant geographic and market characteristics. − …”

Hydrogen energy is a clean and efficient type of green energy whose use has been widely promoted. However, because of its physical and chemical characteristics, hydrogen tends to cause fires and explosions under certain conditions, which restricts its widespread application. After briefly describing the danger of high-pressure hydrogen (HPH), this paper summarizes the ignition and flame propagation characteristics of HPH leakage diffusion and describes the influences of various factors, such as leakage location, initial leakage velocity, initial pressure, presence of vents, ignition location, pipe size, and presence of obstacles, on these characteristics. HPH is likely to ignite spontaneously at the moment of leakage, and this ignition involves complex dynamics. Finally, the gap in the current research on HPH is described, and suggestions are provided for future research to promote the safe and efficient use of hydrogen energy.
