Task 22 started December 1^st 2006. At present there are 53 Experts from 18 countries involved in total 49 projects. The sixth Task 22 meeting was held in Paris , France 11-15 October 2009 with 59 participants. Task 22 will be extended for 3 more years from 1. December 2009.

Hydrogen storage remains as an undisputed problem for hydrogen-fuelled vehicles, and is considered by many to be the most technologically challenging aspect for achieving a hydrogen-based economy. Task 22 addresses hydrogen storage in solid materials. The research efforts will require new materials and solutions, and not simple, incremental improvements in current technologies. The specific goals and objectives for research on hydrogen storage materials in Task 22 are:

A.     Develop a reversible or regenerative hydrogen storage medium fulfilling international targets for hydrogen storage.

B.     Develop the fundamental and engineering understanding of hydrogen storage by various hydrogen storage media that have the capability of meeting Target A.

C.     Develop hydrogen storage materials and systems for use in stationary applications.
