Structural Design and Assessment of Cryogenic Hydrogen Storage Tanks for Aircraft
The aviation industry plays a significant role in global connectivity and economic growthbut has substantial negative environmental impacts, particularly in terms of carbondioxide emissions. According to a study by the European parliament, the aviationindustry accounts for 0,4 % of greenhouse gas emissions within the EU and 3,4% forinternational flights. In response to these environmental issues, liquid hydrogen is seenas a promising choice, offering efficiency as a clean energy source, especially whenproduced through electrolysis, as well as higher energy density per volume, making itattractive for the aviation industry where energy and weight optimization are crucial. However, the challenge of using hydrogen as fuel lies in designing a tank that canwithstand extreme conditions, such as low temperature and high pressure , while alsominimizing the risk of flammability and explosion. Additionally the right materials mustbe chosen to resist hydrogen embrittlement. This project aims to design a hydrogentank for aircraft that meets the requirements specified in this study. This will be achievedthrough a literature review, numerical simulations with SolidWorks FEM to test differenttank shapes and materials, and the use of Python code to calculate different spatialparameters.The results indicate that a cylindrical shape is the most optimal choice for the tank, andfour materials have been identified as suitable, with aluminum alloys showing moreadvantages compared to stainless steel due to reduced weight with similar strength.
