About the presentation
Title: Can we fly safely on liquid hydrogen? Using advanced modelling tools to understand the hazards
In this presentation, Dr Leñero will discuss how advanced modelling using CFD can be used to understand the hazards from potential LH2 release scenarios while refuelling an aircraft and demonstrate how FLACS-CFD can be used to simulate liquid hydrogen spills and their subsequent consequences (gas dispersion, fire, explosion).
These results can then be used to answer questions and provide guidance on issues pertaining to the location and layout of hydrogen refuelling “hubs” at airports, exclusion zones while refuelling aircraft, procedures for refuelling, and appropriate emergency response in case of an accidental release of hydrogen.
About the speaker
Dr Karina Almeida Leñero, Energy Transition Technical Lead @ Gexcon
Dr Karina Almeida Leñero holds a PhD in Chemistry which has enabled her to apply knowledge to the development of energy-efficient processes, including the extraction of second-generation biofuels from marine algae. Passionate about renewable energy, and with a strong scientific background and broad knowledge of process safety, Dr Leñero is also experienced in hazard identification, consequence modelling, dust explosions and risk assessment and mitigation.
