ABSTRACT
It is clear that in the twenty-šrst century much more e£ort will have to be directed at alternative energy sources, of which hydrogen is one of the most promising clean and renewable
energy source. However, the storage, transport, and delivery of hydrogen are important elements in a hydrogen energy system. In mobile applications of hydrogen systems, the storage becomes essential to a sustainable energy economy. Light weight, safe, and high energy density storage will enable the use of hydrogen as a transportation fuel. EÀcient and cost-e£ective stationary hydrogen storage will permit photovoltaic and wind sources to serve as base load power systems.
