With the decreasing supply of fossil fuels and the increasing climate change, traditional energy sources have faced serious challenges. Hydrogen, as a form of clean energy with zero CO<sub>2</sub> emission and very high energy density, is a promising alternative to replace fossil fuels. Unlike fossil fuels, hydrogen gas is not naturally abundant and it requires other energy sources to be generated. Therefore, hydrogen is an energy carrier. In order to be applied in certain applications such as automobiles, the storage of H<sub>2</sub> is vital.  Metal-organic frameworks (MOFs) are an emerging class of porous materials with an extremely high surface area, making them promising candidates for gas storage. An interpenetrated sodalite structure type triazolate based Cu MOF was designed and successfully synthesized. It shows high stability in a variety of pH values and high BET surface area at 2100 m2/g and 2.0 wt% total H2 uptake at 1 bar and 77 K. Under high pressure, it demonstrated a very high weight percentage of hydrogen excess uptake at 5.6 wt%, which exceeds the prediction of Chahine rule.
