Hydrogen storage is a key enabling technology. None of the current technologies satisfy all the hydrogen storage attributes sought by manufacturers and end users.

On this front, Government-Industry coordination on research and development is needed to lower costs, improve performance, and develop advanced materials. Once produced, hydrogen can be in the form of a compressed gas, cryogenic liquid or chemical, each requiring specific methods of storage essential to successful distribution. The unusual physical characteristics of hydrogen present particular problems with regard to its storage. A number of the methods have already been outlined. Some amplification is necessary e.g. pressurized hydrogen gas storage involves two major methods of containment.

• 1. metal tanks using iron or iron compounds as materials of construction
  2. natural containers including depleted oil and gas fields, mines caverns and aquifers

Salt caverns are used for storage of natural gas in many parts of the world. Cryogenic liquid hydrogen storage may not be practical, at present, due to high energy consumption required for the liquefaction process. Exploring higher-risk storage technologies involving advanced materials such as lightweight metal hydrides and carbon nanotubes, etc. is imperative.

The eminent panelists of this session will share insights into the latest developments for hydrogen storage and challenges.
