1.1 Reservoir shape and geometry

In the automotive industry, the design of compressed hydrogen tanks faces particular challenges, linked to limited space, safety and vehicle energy efficiency. It is of prime importance that these tanks are integrated in such a way as to optimize available space, while guaranteeing vehicle safety and performance. Space optimization is a major consideration: tank integration must not encroach on passenger or cargo space. This may require customized designs to maximize hydrogen storage volume, while adapting to the specific dimensions of the vehicle, for example by using longer, slimmer tanks under the floor.

Reservoir geometry is also crucial to safety. Tanks must be able to withstand operating pressures of up to 700 bar, which...
