Hydrogen storage in the hydrogen energy era

Why are hydrogen storage technologies important?

Efficient and safe hydrogen storage technologies are pivotal for the widespread adoption of hydrogen energy. These technologies not only help balance energy supply and demand and enhance energy efficiency but also enable diversified energy use and optimize resource allocation .

How is hydrogen stored in a solid state?

Currently, storing hydrogen through compression and liquefaction methods is the most mature and widely adopted approach. However, the high pressure of gaseous storage and the issue of evaporation loss in liquid storage have driven the continuous development of solid-state storage.

Are hydrogen storage technologies a viable energy source?

Breakthroughs and applications in hydrogen storage technologies address challenges in hydrogen storage and transport, enhancing the efficiency and economic viability of hydrogen as a clean energy source. This study examined the development and evolution of hydrogen storage technologies from varied perspectives, using literature and patent analyses.

What is the development phase of hydrogen storage?

3. Development phase (2017–2023): Research on hydrogen storage has expanded significantly, especially after 2020. Amidst the vigorous emergence of a new wave of technological revolution and industrial transformation globally, emerging energy technologies like hydrogen energy are accelerating their iteration at an unprecedented pace .

How can hydrogen be stored?

Hydrogen can be stored physically as either a gas or a liquid. Gas storage typically requires high-pressure tanks (350–700 bar), while liquid storage requires cryogenic temperatures due to hydrogen's low boiling point of −252.8°C at one atmosphere pressure.

What is a hydrogen storage model for natural gas hydrogen production & storage?

Rajesh, P, and others established a hydrogen storage model for natural gas hydrogen production and storage based on the analysis of energy consumption and energy recovery of natural gas steam reforming hydrogen production unit, as well as multiple energy characteristics of hydrogen storage unit, such as electricity, heat, and gas.
