Introduction to the hydrogen books
-
Andreas Züttel
Abstract
Hydrogen produced from renewable energy represents the most important chemical energy carrier storing renewable energy. It can be produced by water splitting with electricity or thermal energy. The storage of hydrogen, that is, the reduction of the volume, is the challenge of the direct application of hydrogen as an energy carrier. While the density of hydrogen molecules is limited to the density of liquid hydrogen, hydrogen atoms bond to other elements exhibit densities up to greater than twice the density of liquid hydrogen, for example, metal hydrides. The storage of hydrogen at elevated densities requires a sophisticated storage system, which makes the storage more expensive and technically challenging. Hydrogen in hydrocarbons is stored by well-established technology and significantly less expensive than pure hydrogen storage.
