[Title]
Risk Management for Resilient Infrastructure and Hydrogen Systems

[Abstract]
The energy transition and increasing exposure to natural hazards are creating new challenges for risk management across critical infrastructure and emerging energy systems. This presentation will share recent research on proactive risk identification, accident prevention, safety-barrier management, and resilience, with particular emphasis on hydrogen technologies and Natech (natural hazard-triggered technological) risks. It will also provide an opportunity to exchange knowledge and experiences on these topics and explore perspectives for future research and collaboration. The research combines statistical analysis of historical accidents, systematic safety assessment, and vulnerability-based approaches to examine how technological, organisational, and natural hazard factors interact to influence accident risk. Findings from global dam failures and historical hydrogen refuelling station accidents highlight the importance of understanding common failure mechanisms, human and organisational contributors, and the performance of safety barriers. Building on these insights, research on hydrogen-based energy storage, large-scale liquid hydrogen systems, and repurposed gas pipelines examines how natural hazards such as storms, flooding, lightning, and other hydrometeorological events can interact with infrastructure vulnerabilities and hydrogen-specific characteristics. These studies demonstrate the importance of integrating hazard identification, inherent safety, barrier management, emergency preparedness, and targeted mitigation into the design and operation of emerging energy
systems. Overall, the research highlights the need to move beyond conventional, hazard-specific approaches towards integrated and resilience-oriented risk management that accounts for interactions between natural
hazards, technological systems, and human and organisational factors. The presentation will conclude by discussing opportunities for collaborative research on risk-informed approaches to the safe and sustainable deployment of hydrogen and critical infrastructure.
 

[Biography]
Dimitrios is a Spatial Planning and Development Engineer whose research focuses on disaster risk reduction, Natech (natural hazard-triggered technological) accidents, hydrogen safety, social acceptance of hydrogen technologies, and participatory risk management. His research explores how technological systems can be safely integrated into society and how communities, industries, and authorities can strengthen preparedness, response, and governance of
associated risks. His work addresses both the technological and societal dimensions of risk, with particular emphasis on risk management, emergency preparedness, risk-informed decision-making, technology acceptance, and community engagement. He also develops practical approaches to risk awareness and stakeholder participation, including serious games designed to improve understanding of Natech risks and foster community
engagement. At the Norwegian University of Science and Technology (NTNU), Dimitrios contributes to research on the safety and social dimensions of hydrogen technologies, including within the EU-funded H2SCORE project. He has authored and co-authored more than 40 peer-reviewed international publications, including journal articles, book chapters, and conference papers.
