Type of article: Periodical article

Summary

THE OBJECTIVE OF THIS STUDY HAS BEEN TO PROVIDE A GENERAL REVIEW OF HOW THE EARTH CAN BE USED AS A STORAGE MEDIUM FOR SEASONAL STORAGE OF (PRIMARILY) SOLAR ENERGY IN THE FORM OF HEAT. STORAGE IN DEEP CONFINED GROUNDWATER RESERVOIRS (AQUIFER STORAGE) IS SEEN AS AN INTERESTING ALTERNATIVE, WHICH HAS BEEN DEALT WITH IN DETAIL IN THE STUDY BOTH FROM A TECHNICAL AND AN ECONOMIC VIEWPOINT. A COMPREHENSIVE DESCRIPTION OF THE WELL AND AQUIFER FUNCTIONS, TOGETHER WITH THE HEAT TRANSFER PROCESSES. THE RESULTS SHOW THAT DEEP STORAGE IS TECHNICALLY FEASIBLE WITHIN SEVERAL DENSELY POPULATED PARTS OF SWEDEN. THE EFFECTIVE COST OF STORAGE, BASED ON THE ANNUAL CAPITAL AND OPERATING COSTS, IS AROUND 10 ORE / KWH IN ALL THREE CASES. FIELD TRIALS WITH AQUIFER STORAGE ARE PLANNED FOR THE AREA AROUND JONKOPING. THE DETAILED PROJECT PLAN FOR THESE TRIALS IS IN PROCESS OF PREPARATION.
