The current state-of-the-art for hydrogen storage is compressed H-2 at 700 bar. The development of a liquid-phase hydrogen storage material has the potential to take advantage of the existing liquid-based distribution infrastructure. We describe a liquid-phase hydrogen storage material that is a liquid under ambient conditions (i.e., at 20 degrees C and 1 atm pressure), air- and moisture-stable, and recyclable; releases H-2 controllably and cleanly at temperatures below or at the proton exchange membrane fuel cell waste-heat temperature of 80 degrees C; utilizes catalysts that are cheap and abundant for H-2 desorption; features reasonable gravimetric and volumetric storage capacity; and does not undergo a phase change upon H-2 desorption.
