Hydrogen transport and storage

Such tanks with compressed hydrogen are said to have been used to supply relatively small stationary fuel cell power plants. Considering the unfavorable 

In recent years, versions of fighter tanks have been developed, such as tanks made of fiber-reinforced plastic. The weight figures of such tanks are twice as good as those of steel tanks, but the volume figures are practically the same. 

The work toward practical hydrogen storage systems using metal hydrides is very promising, but still in an early stage, and numerous problems associated with the kinetics of the processes and the stability of the systems remain to be solved. Many of these points have been discussed by Eberle et al. (2006). 

Subsequent investigations have not confirmed the initial data. In fact, very remarkable physical adsorption of hydrogen does occnr on the nanostrucmres, but does not go beyond 3 wt%. 

The possibihty of using carbon fibers as hydrogen-adsorbing materials for power sonrces was demonstrated by Danilov et al., (2008). Activation of the nanofibers in melted KOH resulted in increasing their specific snrface area from an initial 300 to 400 m /g to 1700 m /g. Deposition of copper improved the electrochemical storage characteristics.
