Chemical and hydrogen energy storage

What are chemical-based hydrogen storage systems?

A detailed discussion of chemical-based hydrogen storage systems such as metal hydrides, chemical hydrides (CH 3 OH, NH 3, and HCOOH), and liquid organic hydrogen carriers (LOHCs) is presented. Furthermore, the recent developments and challenges regarding hydrogen storage, their real-world applications, and prospects have also been debated.

Can hydrogen be stored in water?

When the hydrogen absorption reaction of an absorbing material takes place in water, hydrogen can be stored in both. This type of hydrogen storage is called chemical hydrogen storage. In chemical hydrogen storage, the chemical hydride can be either a solid or a liquid.

What are chemical hydrogen storage materials?

Chemical hydrogen storage materials are compounds that generally have the highest density of hydrogen in either solid or liquid form and are categorized as covalently bound hydrogen. The DOE's final report for the Chemical Hydrogen Storage Center of Excellence provides more information on this topic.

What materials are used for hydrogen storage?

Extensive researches have been conducted to hydrogen storage materials as well, including physical adsorption materials like metal-organic frameworks , carbon nanotubes and zeolites , and chemical materials such as metal hydrides and complex hydrides .

What are the different methods of hydrogen storage?

Different methods for hydrogen storage are discussed, including high-pressure and cryogenic-liquid storage, adsorptive storage on high-surface-area adsorbents, chemical storage in metal hydrides and complex hydrides, and storage in boranes.

Is hydrogen a viable energy carrier?

The stuff dreams are made of: Hydrogen is a promising energy carrier in future energy systems, but the storage for mobile and stationary applications is a substantial challenge. If on-board hydrogen storage of car running on a fuel cell can be solved, then also the other problems of a hydrogen infrastructure appear to be manageable.
