Abstract
In this chapter, an analysis of the usage of hydrogen storage technologies for the design and construction of effective thermally driven hydrogen compressors is presented. A discussion on the available technologies for compressing hydrogen is presented; followed by an analysis of the combination of metal hydrides to design a metal hydride hydrogen compression (MHHC) system. The physicochemical and thermodynamic aspects of the metal hydride formation is introduced and the most suitable materials for compression processes are considered and analyzed. The necessity for the development of an accurate numerical analysis to describe a multistage MHHC system is explained, analyzed and discussed.
Keywords: Hydrogen storage, metal hydrides, hydrogen compression, thermally driven compressor, intermetallic compounds, numerical analysis, renewable energy
