Solid-state hydrogen energy storage device

Can solid-state hydrogen storage materials be used for hydrogen energy storage?

Energy drives the development of human civilization, and hydrogen energy is an inevitable choice under the goal of “global energy transition”. As hydrogen technology continues to advance, solid-state hydrogen storage materials have attracted significant attention as an efficient solution for hydrogen energy storage.

What is a hydrogen storage material?

The hydrogen storage material is the core of solid-state hydrogen storage, and its performance directly determines the system’s hydrogen storage capacity, kinetics, cycle life and other indicators.

What are the different types of solid-state hydrogen storage?

Solid-state hydrogen storage can be categorized into two main types: physical adsorption and chemical adsorption, as illustrated in Figure 1 . Physical adsorption, also known as physisorption, is a process where gas molecules adhere to a solid surface through van der Waals forces without undergoing any chemical reactions.

How is hydrogen stored in a solid state?

Solid-state hydrogen storage Hydrogen can also be stored in solid state, either by physisorption or by chemisorption. In physisorption, molecular hydrogen adsorbs on the solid surfaces via van der Waals interactions .

Can hydrogen storage be integrated into energy-efficient devices?

The research of multifunctional materials that may combine hydrogen storage with additional capabilities, such as thermal storage, catalysis, or electrical applications, needs to be further explored. The development of such materials would encourage hydrogen storage to be integrated into diverse and energy-efficient devices.

What is the thermal management subsystem of solid-state hydrogen storage device?

The thermal management subsystem of the solid-state hydrogen storage device provides effective thermal management to maintain the temperature inside the device at a beneficial level to ensure that the MH material has the desired rate of hydrogen absorption/release.
