Hydrogen, H2, is a chemical compound of two hydrogen atoms, the most common element we know of. Hydrogen is odorless, colorless, and highly flammable. Hydrogen, however, is very volatile, which means that it dissolves quickly in the air and becomes harmless. When hydrogen gas meets oxygen, large amounts of energy is released.
The large-scale storage of hydrogen plays a fundamental role in a potential future hydrogen economy. Although the storage of gaseous hydrogen in salt caverns already is used on a full industrial scale, the approach is not applicable in all regions due to varying geological conditions. Therefore, other storage methods are necessary.
The goal of hydrogen storage technologies is to enhance the energy density of hydrogen and improve its storage and utilization efficiency. By developing …
