Why is heat exchanger design important for metal hydride based hydrogen storage?

Because of the need for fast refueling rates, thermal management of the storage system is very important. Good heat exchanger design is crucial for a metal hydride based hydrogen storage system in order to maximize gravimetric and volumetric storage densities of the bed and to meet system performance requirements.

Is helical coil heat exchanger a viable hydrogen storage system?

However, the helical coil heat exchanger could be a useful design for metal hydrides with higher absorption capacity and faster kinetics and the implementation of such optimized heat exchanger designs can be very effective in designing a viable hydrogen storage system.

What is the function of thermochemical heat storage material in hydrogen charging?

During the hydrogen charging process, the thermochemical heat storage material is used to cool the metal hydride. In the process of discharging hydrogen, the thermochemical heat storage material acts as the heat driving source of the metal hydride.

What is a good heat exchanger design?

Good heat exchanger design is crucial for a metal hydride based hydrogen storage system in order to maximize gravimetric and volumetric storage densities of the bed and to meet system performance requirements. Design of a heat exchanger is governed by the operating pressure and temperature conditions.

Is refueling of metal hydride based hydrogen storage systems exothermic?

Refueling of metal hydride based hydrogen storage systems is a highly exothermic process. Because of the need for fast refueling rates, thermal management of the storage system is very important.
