As the world’s energy demands continuously increase, the use of hydrogen and its isotopes as alternative sources of energy is attractive due to its renewability and sustainability. Hydrogen absorption and desorption using metal hydrides have been widely investigated for hydrogen storage, purification, and isotopic separation due to their high storage capacities and moderate desorption, temperatures and pressures. For practical on-board applications, cheap and easy hydrogen storage and release must be realized. Hydrogen absorption and desorption must be sufficiently fast, reversible, and energy efficient, without affecting material properties. In this talk, I will demonstrate that energy, in the form of an induced alternating electromagnetic field (AEMF), is selectively coupled to hybrid magnetic-hydride materials for the selective and controlled release of hydrogen gas isotopes.
