TL;DR: In this article, the results of the experiments performed have been compared with the SAE J2601 look-up tables for non-communication fillings, and a big safety margin has been observed in these tables.

TL;DR: In this article, the influence of the initial tank temperature on the evolution of the internal gas temperature during the refuelling of on-board hydrogen tanks is investigated, and it has been found that the final gas temperature increases linearly with the increase of the original tank temperature while the temperature increase (ΔT) and the final state of charge (SOC) decrease slowly with increasing the initial temperature.

TL;DR: In this article, the thermal behavior of several commercial hydrogen tanks (Type III and Type IV) has been studied during high pressure hydrogen cycling (filling from 2 − 3 MPa to 78 − 84 MPa, holding under pressure and emptying back to 2 - 3 MPA).

TL;DR: In this article, on-board hydrogen tanks have been subjected to filling and emptying cycles to investigate their long-term mechanical and thermal behavior and their safety performance at the JRC-IET.

TL;DR: In this article, defueling experiments of two different types of on-board hydrogen tanks (Type III and Type IV) have been performed in all the range of expected defueing rates and the lowest temperatures have been found on the bottom part of the Type IV tank in very fast defuelings.
