Briefly describe the role of hydrogen energy storage

How can hydrogen be stored as a fuel?

While hydrogen has great potential as an energy carrier, its low energy density makes it more difficult and expensive to store and transport for use as a fuel. Several storage methods can address this challenge, such as compressed gas storage, liquid hydrogen storage, and solid-state storage.

What are the main challenges in storing hydrogen as a fuel?

Storing and transporting hydrogen for use as a fuel is more difficult and expensive due to its low volumetric energy density (Rivard et al. 2019). Several storage methods can address this challenge, such as compressed gas storage, liquid hydrogen storage, and solid-state storage.

What is hydrogen energy storage?

Hydrogen energy storage is the process of production, storage, and re-electrification of hydrogen gas. You might find these chapters and articles relevant to this topic. Hydrogen energy storage is one of the most popular chemical energy storage . Hydrogen is storable, transportable, highly versatile, efficient, and clean energy carrier .

What makes an ideal hydrogen storage system?

An ideal hydrogen storage system should possess both high volumetric and gravimetric energy densities, rapid energy intake and release kinetics, be applicable in standard operational temperature and pressure conditions, have inherent safety and be economically viable.

Why should hydrogen storage solutions be developed?

The successful development of hydrogen storage solutions is essential for the penetration of hydrogen at each level of the energy supply chain. The application of hydrogen in the energy economy can be attributed to two categories: stationary and mobile.

What is the advantage of storing hydrogen as a liquid?

The advantage of storing hydrogen as a liquid is that it has a much higher energy density than compressed hydrogen gas, which means that a larger amount of hydrogen can be stored in a smaller volume (Li et al. 2021; Tan et al. 2012). Cryogenic storage tanks are typically used for low-temperature hydrogen storage.
