Nicola Paltrinieri is a Professor of Risk Assessment at the NTNU Department of Mechanical and Industrial Engineering, and leads the NTNU Team Hydrogen. He joins us to discuss the complexities of hydrogen safety and its role in the energy transition. The conversation starts off by bringing up an earlier podcast episode. In episode 44, Professor Robert Warren Howarth, co-author of the controversial paper "How Green is Blue Hydrogen?" was a guest. Professor Paltrinieri was part of a comment team that aimed to provide a more balanced view of that paper, and helps us understand the nuances of the debate surrounding the paper, emphasizing the importance of data accuracy, context, and diversification in investment. Following the blue hydrogen discussion, the conversation shifts to hydrogen safety. Professor Paltrinieri explores the complexity of hydrogen safety, emphasizing that it involves multiple factors beyond just combustion and explosion risks. He addresses the challenges of working with an emerging technology where operational experience is limited, leading to uncertainties in statistical analysis. Additionally, he discusses the interaction between human factors and technology, and the need for effective inspection and maintenance strategies.
