Advancing Hydrogen Tank Safety with Cutting-Edge Detection and Ventilation Systems in Maritime and Aerospace Sectors

The presentation delves into the safety aspects of hydrogen (H2) tank systems in various mobility sectors, focusing on mechanical and functional safety. It notes that while interest in hydrogen spans all sectors, progress varies by maturity levels. The discussion centers around specific safety concerns for mobile applications rather than general H2 challenges or benefits. Mechanical safety involves ensuring adequate wall thicknesses to withstand impacts, supported by testing scenarios. Functional safety requires integrating sensors and actuators monitored for proper operation; failures here could lead to significant issues. A high-pressure system ranging from 350-700 bar is examined with temperature and pressure sensors linked through a rail leading up to mid-pressure areas managed by regulators safeguarded via blow-off lines during excessive pressures. Key components include an integrated control unit connected both within vehicles and externally for command inputs necessary for correct functioning—ensuring reliability before deployment through rigorous risk assessments culminating in technical architecture tests. In maritime and aerospace sectors, H2 detection and ventilation are crucial preventive strategies due to operational risks associated with closing tank valves entirely; alternative methods like partial closure or inert gas flushing are suggested instead. Disparities exist across industries regarding codes/standards—with automotive/machinery being more advanced compared to maritime/aerospace fields—and leveraging mature areas' experiences can enhance other domains’ systems architecture. ITK Engineering GmbH offers services spanning concept development through series production support including type approval assistance at an event featuring 3000 exhibitors inviting attendees interested further engagement on these topics encouraging physical activity counting steps taken during visits.
