However, the reliability and safety of key subsystems, such as high-pressure hydrogen storage, fuel cells, and Balance of Plant (BoP) components, remain major barriers to large-scale deployment. This review evaluates the emerging role of Artificial Intelligence (AI)-driven Predictive Maintenance (PdM) in overcoming these challenges and advancing the sustainability of hydrogen mobility systems. Integrating Internet of Things sensing, digital twin modeling, and advanced data analytics, AI-based PdM enables early fault detection, anomaly diagnosis, and accurate estimation of component remaining useful life, thereby minimizing unplanned downtime and extending service life. Moreover, prescriptive maintenance approaches, which provide actionable recommendations in addition to failure prediction, are discussed as a next step toward autonomous maintenance management. The review also examines enabling technologies such as edge computing, federated learning, and human–machine interfaces that enhance data security, responsiveness, and operator interaction. Persistent challenges, including data heterogeneity, algorithm interpretability, cybersecurity threats, and the absence of regulatory frameworks, are critically analyzed. Finally, future perspectives highlight the need for standardized assessment protocols and cross-disciplinary collaboration to ensure safe, scalable, and intelligent adoption of AI-based PdM in hydrogen-powered transport. Overall, this review provides a comprehensive assessment framework connecting predictive intelligence, system resilience, and sustainability in next-generation hydrogen mobility.</div></div>","PeriodicalId":16291,"journal":{"name":"Journal of Loss Prevention in The Process Industries","volume":"101 ","pages":"Article 105953"},"PeriodicalIF":4.2,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146191258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The advent of artificial intelligence (AI) has augmented safety management proficiencies by facilitating the early identification of leakage precursors, alleviating alarm saturation, enhancing incident diagnostics, and bolstering risk-informed maintenance of essential assets. Nonetheless, the implementation of AI in safety-critical contexts remains constrained by issues related to data integrity and provenance, model generalization, system resilience, and cybersecurity vulnerabilities. This review amalgamates recent AI methodologies pertinent to process safety and critically assesses the impediments to their dependable industrial application. Four principal application sectors are scrutinized: (i) Natural Language Processing (NLP) for the analysis of incident and near-miss reports, (ii) multivariate anomaly detection for precursor identification, (iii) adaptive alarm management for dynamic prioritization, and (iv) computer vision for real-time surveillance of hazardous zones and personal protective equipment (PPE) compliance. A structured assurance framework is proposed that encompasses data governance, fault-based validation, model interpretability, compatibility with existing safety systems, and alignment with cybersecurity protocols. A phased deployment roadmap from shadow operation to advisory and controlled execution is delineated, underpinned by performance indicators such as Δ-risk reduction, response latency, false-alarm expense, barrier reliability, and model learning rate. The review further underscores alignment with the United Nations Sustainable Development Goals, particularly SDG 9 and SDG 12, by advocating for safer, more resilient, and sustainable industrial operations.</div></div>","PeriodicalId":16291,"journal":{"name":"Journal of Loss Prevention in The Process Industries","volume":"101 ","pages":"Article 105956"},"PeriodicalIF":4.2,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146191369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The presence of two nitro functional groups in its molecular structure results in substantial heat release during thermal decomposition. An insufficient understanding of its decomposition behavior can lead to severe thermal runaway incidents in industrial production. To investigate the thermal hazard characteristics of CDNB under various acidic environments, this study was designed based on a representative industrial accident scenario. A systematic analysis was carried out using differential scanning calorimetry (DSC) and accelerating rate calorimetry (ARC), combined with kinetic modeling, to thoroughly investigate the thermal decomposition behavior and runaway potential of CDNB. Experimental data revealed that the decomposition enthalpy of CDNB exceeds 4000 J/g, demonstrating intense exothermicity and a clear tendency for thermal runaway. Moreover, the time to maximum rate under adiabatic conditions (TMR<sub>ad</sub>) was found to be less than 1 h, with a corrected adiabatic temperature rise (ΔT<sub>ad</sub>,f) of 1680.4 K. Based on these thermal safety parameters and risk matrix assessment, the thermal runaway risk level of CDNB was evaluated as Level 3, corresponding to an “unacceptable risk” category. Notably, in the ARC experiment, the addition of sulfuric and nitric acids significantly lowered the initial decomposition temperature of CDNB. Their catalytic effects became more pronounced with increasing acid concentrations, with the temperatures being reduced by up to 40.2 °C and 50.0 °C, respectively. Under different acidic conditions, the activation energy of CDNB decreased by 14.3–99.0 kJ/mol, significantly increasing the likelihood of thermal hazard events.
