Hydrogen Generation and Storage in Porous Silicon

Valeriy A. Skryshevsky, Vladimir Lysenko, and Sergii Litvinenko

13.1 Introduction

In recent years, it has become increasingly clear that hydrogen appears as a new energy carrier instead of the traditional carbonaceous fuels. One of the key roadblocks to the widespread use of hydrogen as a renewable fuel is hydrogen storage.

Three main options exist for storing hydrogen (Tzimas et al. 2003):

1. As a highly compressed gas
2. As a cryogenic liquid
3. In a solid matrix

Most automakers are considering either the high-pressure gaseous hydrogen (passenger vehicles) or cryogenic liquid (also known in rockets applications). However, these first two technologies are fraught with public perception issues ...
