Equipment group and procedure for storage of heat energy using electric current

Abstract

Equipment for storage of heat energy preferably for storage of heat energy by converting electric energy produced by plants utilizing wind energy into heat energy and using the stored heat energy for providing various heat supply services, and, in order to eliminate the disadvantages due to the intermittent operation of plants utilizing wind energy, using the stored heat energy for generating electric energy during windless period; furthermore, storing the energy by means of cheap electric energy produced by the power stations during night and using it during peak load periods.

Description

technical field [0001] The invention relates to a set of devices and a process for storing thermal energy using electric current Background technique [0002] Energy reserves are limited in the world; their extraction is becoming increasingly expensive. In particular, the predicted severe shortage of petroleum reserves in the middle of this century will cause severe problems and energy shortages; in fact, the problem of using petroleum derivatives that are mostly burned as a substitute has not yet been solved. At the same time, since fossil fuels are burned, the pollutants sent into the environment cause serious environmental pollution and increase the carbon dioxide content in the atmosphere, thus aggravating the "greenhouse" effect with its serious consequences. Sulfur dioxide sent into the atmosphere leads to acid rain which causes significant damage to the biosphere. [0003] In order to solve these problems which are becoming more and more serious both for the present...

Problems solved by technology

[0031] The disadvantage of this type is that the melt generated from amorphous material is used for heat storage using heating i.e. different from the heat released from phase transition, therefore, it cannot achieve high heat storage capacity and long-term heat storage
