In addition, the temperature level required for sodium-powered accumulators must not drop below 294°C as it can cause the ‘freezing’ of sodium, resulting in serious problems and requiring an additional energy system to be used in case of occasional power shortages.
Also, our accumulator is based on volcanic material, which is not easily shattered and is not fragmented during its usage.

The system is designed to accumulate sufficient energy during the 8h of sunlight to produce electricity 24h per day. It should be added that our thermal accumulator can preserve energy for one year at 800°C and thermal loss during the year does not exceed 10%.

With today’s level of technology, no other existing system is capable of producing electrical energy 24h per day using 8 hours of sunlight.

The current systems mainly use turbines and water evaporation and, with the low temperatures achieved, the efficiency of those systems cannot be compared with the newly developed design.
Our system, as a completely new solution on the market, uses a specially developed air turbine, which is thermodynamically designed so as to achieve high level of efficiency. 

Capital investment, relative to the produced energy at the annual level, should be around 350€/MWh. It should be noted that the electrical energy is produced by this system 8760h/Year.

It is also important to note that none of the current systems in the world is capable of producing electrical energy from solar energy 8760h per year without an additional energy source, as the energy is produced only during the sun-hours.

Today, the PV investment costs are in the range of 600€/MWh and with parabolic refractors and heliostat mirrors in the range of 1600 -1700€/MWh, however, in each of these cases, solar energy is produced only during the sun-hours.
