A consideration of power density and hydrogen production and utilization technologies

The development of hydrogen (H2) production systems and equipment utilizing hydrogen fuel is a key factor in the creation of a worldwide hydrogen energy network. The World Energy Network (WE-NET) project made significant progress in its development work in FY2002, especially in the critical area of hydrogen fueling stations. This report will examine some of the highlights of the FY2002 WE-NET project, and will also consider the impact of power density on fuel cell cost. Hydrogen production method also evaluated by scale merit (kW/m3).
