This tutorial will examine novel hydrogen storage materials currently being developed for “on-board” applications that require several challenging constraints, including high-volumetric and gravimetric storage densities. The instructors from the Department of Energy’s recently established Centers of Excellence for vehicular hydrogen storage will focus on the three material classes chosen by DOE ─metal hydrides, chemical hydrides, and carbon-based materials─as the most promising for meeting these stringent requirements. After a brief introduction and overview, each of these material classes will be discussed in detail, evaluating their material properties across common themes and benchmarks.
