The Chemical Heat Pipe EVA and ADAM

Abstract

The interdisciplinary system described, for the transport of energy over long distances, has been under active investigation on a pilot plant stage for some years. Heat from a high temperature gas cooled nuclear reactor is proposed as an energy source to convert methane and steam, an endothermic chemical reaction, into carbon oxides and hydrogen – the EVA proces. The resulting gases can be pumped through pipes over long distance and, at the point of energy requirement, be converted back as an exothermic reaction – the ADAM process. Both reactions have been tested at Jülich with success and could be commercially Introduced at the end of the present century. Additional advantages are described for this closed circuit chemical heat pipe system.
