Hydrogen emerges as a pivotal element in achieving fossil-free transportation, offering a sustainable alternative to conventional fossil fuels and significantly reducing environmental impacts. This report outlines the development of a cutting-edge Type V high-pressure vessel employing carbon fiber composite material, aimed at tackling the challenges associated with liner less hydrogen pressure vessel. Current research focuses on addressing two major challenges, namely manufacturing complexity and leak tightness of the tank. Manufacturing complexity of the tank is thoroughly addressed, covering various removable mandrel technologies and further a novel integral mandrel technique is introduced, featuring a carbon fiber-reinforced polymer (CFRP) structure. Another significant challenge is ensuring the leak tightness of the tank without a polymer liner. The current article explains this issue in detail and discusses various solutions for a liner less, leak-tight tank structure. While Type V pressure vessels offer advantages in weight and storage capacity, their integration into automotive applications requires addressing manufacturing complexity, leak tightness, material compatibility, and cost-effectiveness. By overcoming these obstacles, the full potential of Type V tanks in hydrogen vehicles for the transportation sector can be realized, fostering sustainable mobility solutions.     «
