Liquid Phase Chemical Hydrogen Storage: From Recent Developments To Future Objectives

Abstract

The hydrolytic dehydrogenation of aqueous boron-nitrogen (B-N)-based compounds such as NaBH4 and NH3BH3 has received much attention, and because of their high hydrogen content they have been shown to be promising hydrogen carriers for storage and transportation. Formic acid (HCOOH), a major product formed in biomass processing, has been intensely investigated for liquid phase chemical hydrogen storage owing to its high energy density, stability, and nontoxicity. In this chapter, we focus on advances in research on hydrogen storage and release of these liquid phase hydrogen storage materials. Main advantages and drawbacks of these systems in liquid phase hydrogen storage are also discussed. © 2018 Elsevier Inc. All rights reserved.
