 Hydrogen is a gas at normal temperatures and can be compressed and stored in cylinders to overcome volume related limitations. It can also be kept as a liquid at temperatures of minus 423 degrees Fahrenheit (-423° F or -253° C). When cooled to a liquid state, this low-weight fuel takes up 1/700 as much space as it does in its gaseous state. In consumer applications, hydrogen storage faces a number of challenges. The main issue is safety as hydrogen is highly volatile. Also, the size, volume and temperature requirements for the storage of hydrogen are not yet practical in small scale uses such as motor vehicles and portable applications. The lack of a distribution system for hydrogen further adds to the storage challenges.
