Market Opportunity

Global demand for hydrogen storage materials and technologies likely reached $3.4 billion in 2015 and could pass the $5.4 billion mark in 2021. Strong growth is expected in this market, with annual growth rates projected to be 8.1% between 2016 and 2021, according to a report by BCC Research.


This technology relates to a flexible free-standing nano-film for hydrogen storage. The excess hydrogen uptake capability of this material is 2.1 wt% at 35°C and 10 bar, which is one of the highest capacity reported to date for physi-sorption nanomaterials under conditions of ambient temperature and safe pressure.

The raw materials are low cost and the reactions are very fast, requiring just a few minutes. Compared with the irreversible hydrogen chemisorption in metal hydrides, the desorption isotherms of hydrogen in this material can return to its original value. Based on laboratory tests, this material shows fully reversible adsorption-desorption of hydrogen even after 10 cycles.
