“…Being cleaner and more effective than petrol, hydrogen has been recognized as the primary choice for future fuels in automobiles (Maus et al, 2008;Zhao et al, 2012). Because of the recent developments in hydrogen fuel technology, the spread of hydrogen fuelling stations has gained more attention in the world (Rigas and Sklavounos, 2005;Schoenung et al, 2006).…”

“…Because of the recent developments in hydrogen fuel technology, the spread of hydrogen fuelling stations has gained more attention in the world (Rigas and Sklavounos, 2005;Schoenung et al, 2006). Studies indicates that 80 to 90% of hydrogen is stored using high-pressure compression in hydrogen fuelling stations and vehicle cylinders (Tzimas and Filiou, 2003), due to the advantages of being more practical, dependable, durable and admissible (Zheng et al, 2008;Maus et al, 2008;Zhang et al, 2006) as compared to other methods.…”

-Complete modelling of the filling process occurring in a hydrogen-fueled vehicle storage cylinder is examined. A simultaneous modelling of the flow and heat transfer within the cylinder and cylinder wall has not been considered in previous studies. Rapid filling may result to an unexpected temperature rise and breaching of the safety standards. In the present study, initially a correlation was developed based on a numerical simulation for predicting the heat transfer rate between in-cylinder flow and the cylinder inside wall. Then, a thermodynamic model was developed for predicting transient variations of temperature and pressure inside the cylinder and wall temperature during the filling. The model was applied to a type III onboard storage cylinder filling process. The numerical results are compared with previously measured values and showed good agreement. The results also show that a great portion of heat dissipation from the incylinder flow is stored in the cylinder wall. It is also found that ambient temperature during the refueling process has considerable effects on filling behavior in general and in particular on the final in-cylinder temperature and filled mass.

“…Possible options are gaseous, liquid, and carrier-based delivery pathways, with the latter storing hydrogen in any chemical state other than free molecules [19]. Presently, the state-of-the-art for onboard hydrogen storage are compressed gaseous tanks with pressures of 350 and 700 bar and cryogenic liquid tanks [20] with high-pressure storage being the technology most applied in vehicles [21]. An analysis in Reference [22] concludes that using hydrogen carriers in a pathway that discharges hydrogen at the station and supplies compressed hydrogen to vehicles will hardly, or not at all, reduce the costs for fueling stations because there is still a need for compressed hydrogen equipment at the fueling station.…”

“…The main dimensions of the cryogenic pressure vessel are listed in Table 1. The total surface area of the throat between the pressure vessel and the jacket is 0.45 cm 2 . This area corresponds to a 7.62 mm diameter hole, equal to the bullet caliber necessary for pressure vessel certification [23].…”

We have modeled sudden hydrogen expansion from a cryogenic pressure vessel. This model considers real gas equations of state, single and two phase flow, and the specific "vessel within vessel" geometry of cryogenic vessels. The model can solve sudden hydrogen expansion for initial pressures up to 1210 bar and for initial temperatures ranging from 27 to 400 K. For practical reasons, our study focuses on hydrogen release from 345 bar, with temperatures between 62 K and 300 K. The pressure vessel internal volume is 151 Liters. The results indicate that cryogenic pressure vessels may offer a safety advantage with respect to compressed hydrogen vessels because i) hydrogen, when released, discharges first into an intermediate chamber before reaching the outside environment, ii) working temperature is much lower and thus the hydrogen has less energy. Results indicate that key expansion parameters such as pressure, rate of energy release, and thrust are all considerably lower for a cryogenic vessel within vessel geometry as compared to ambient temperature compressed gas vessels. Future work will focus on taking advantage of these favorable conditions to attempt fail-safe cryogenic vessel designs that do not harm people or property even after catastrophic failure of the inner pressure vessel.
