Magnesium-based materials for hydrogen storage: Recent advances and future perspectives

Hydrogen storage is a real challenge for realizing “hydrogen economy” that will solve the critical issues of humanity such as energy depletion, air pollution, greenhouse emission and climate change. Recently, tremendous efforts have been devoted to this internationally focused area. Magnesium (Mg) is among the most promising candidates for this purpose and attracts numerous research interests. This paper is aiming at reviewing recent literatures on approaches and progress, the necessity of further research, and future direction to the research of Mg for hydrogen storage.
