Issues of heat energy accumulation using solid masses in order to create heat
accumulators in the future

Abstract

The researches related to the problems related to energy accumulation and its storage are presented in
the paper.  In particular,  the issues related to green energy were studied and involve the creation of
ecologically clean and efficient thermal accumulators in the future. Researches were mainly conducted
to select the optimum for heat storage from various silicate materials and to develop an efficient
construction of the heat accumulator. It was found that good results are obtained if a mixture of sand
and gravel is used for heat accumulation. When developing the construction of the heat accumulator,
its good thermal insulation is important. Which, in turn, reduces losses both during heating and when
storing thermal energy and increases the efficiency of the thermal accumulator.

Keywords: Heat accumulator, energy, sand.
