Thermal insulation materials for non-conventional energy

Abstract

Developed geocement-based perlite thermal insulation material is considered the most suitable for use as insulation of alternative energy facilities for energy storage. The material is characterized by the following values: density 321 kg/m 3 , thermal conductivity, 0.0727 W/m K, the average coefficient of thermal resistance of 2.1 m 2 K/W, thermal cycles 145-148. This material ensures minimum heat loss in underground storage of energy when its thickness is 260 mm.
