A review on transportation of heat energy over long distance: Exploratory development
Résumé
This paper presents a review on transportation of heat energy over long distance. For the transportation of high-temperature heat energy, the chemical catalytic reversible reaction is almost the only way available, and there are several reactions have been studied. For the relatively low-temperature heat energy, which exists widely as waste heat, there are mainly five researching aspects at present: chemical reversible reactions, phase change thermal energy storage and transportation, hydrogen-absorbing alloys, solid–gas adsorption and liquid–gas absorption. The basic principles and the characteristics of these methods are discussed.
