Lindblom, U E

Compressed air energy storage systems (CAES) require that substantial storage volumes can be created underground. In hard rock geologies, rock caverns can be mined to store the air. This report mainly deals with unlined cavern concepts, in particular, caverns without water compensation. In this concept, the air pressure will be variable. Turbomachineries with constant and variable inlet pressure designs for use with uncompensated caverns are discussed in the report. Compensated caverns are used as reference. The report also discusses various principles of constructing large caverns for CAES. In this context, traditional as well as some new mining techniques are described. Conceptual layouts for various CAES plant sizes are selected for economic evaluation. The report also provides a comprehensive evaluation of geotechnical aspects associated with highly compressed gas in hard rock caverns. 30 refs., 46 figs., 13 tabs.
