Carbon Dioxide Capturing for Purifying Hydrogen Generated by Formic Acid Decomposition

Hydrogen is recognized as an ultimate fuel due to its clean burning and its capacity to convert chemical energy to electricity and vice versa. Nonetheless, hydrogen is also known as a hazardous material which entails strict compliance with safety regulations. Consequently, numerous research laboratories are seeking for safe chemical and physical methods for hydrogen storage. Formic acid which is evidently an attractive hydrogen carrier can be decomposed to hydrogen and carbon dioxide in a catalytic reaction. The main disadvantage of this reaction is the carbon dioxide emission. In this study, we present an alternative method to capture carbon dioxide from the gas stream. Furthermore, we suggest a pathway for storing the hydrogen that was produced.
