Application

Calcium hydride (CaH₂) is a metal hydride that can be used for a variety of greener applications such as:

fabrication of hydrogen storage systems for fuel cell applications
synthesis of porous aromatic frameworks (PAFs) for adsorption of organic pollutants
formation of high temperature superconductors

Calcium hydride is widely used as a drying agent for organic solvents.1 It has been used to dry ε-caprolactone,benzene and toluene.
