Abstract

Mass and heat transfer in connection with the storage of hydrogen in metal hydrides O. Schmidtke, J. Hapke Department of Plant System Design, Technical University of Hamburg- Harburg, Germany. Abstract Hydrogen is a very promising alternative to replace conventional energy sources such as coal, oil and natural gas e.g. to avoid air pollution caused by carbon dioxide emissions. That's why the efficient (rapid, dense, secure) storage of hydrogen is of vital importance. One possibility is to store hydrogen as a metal- hydride. This paper contains two topics. The first point is to determine the kinetics of the reaction of the hydride being formed, and the heat transport in a metal- hydride storage. These calculations, based on FORTRAN, are necessary in addition to PHOENICS, which is a commercial flow simulation program. Mainly, the transport of heat is an important aspect because the released heat, in case of the hydrogen absorption, can not be transported out of the reacti
