It has been known for a long time that it is possible to store thermal energy in salt. The energy is stored chemically, by separating salt from water, and then released by combining them again. The problem with regular salt is that the process of combining and separating the salt could only be repeated a few times. After repeated times of the chemical reaction, the salt crystals start to grow bigger and sticks together, which hinders an effective chemical reaction.
The SaltX nano-coating prevents the stickiness, and makes the salt retain its original single crystal form. The advantage of this is that you can charge and discharge energy thousands of times without losing the advantages of the salt crystals or performance. When the salt is treated with nano-coating it also possesses the property of being non-corrosive (preventing rust) unlike ordinary salt. It provides a long-term and cost-effective solution. SaltX is non-toxic and can be recycled.
The key in the technology of SaltX is that the salt can be charged and discharged thousands of times without losing its characteristics. The technology works very much like a battery.
A simple way to describe it, saltwater is boiled which leads to the salt and water being separated from each other. A dry salt is what remains in the chamber.
The boiling water ends up in a second and separate vessel. A valve is closed and keeps the two from each other, the boiling water condenses.
When opening the valve, the water then reunites with the salt, a chemical reaction takes place and heat energy is released. The vessel where the water has been during the separation, gets very cold due to an equalisation of the energy balance.
The charge and recharge process of the salt takes place in a closed vacuum system. Therefore, it can be repeated almost an unlimited number of times. The salt can be heated/charged with any energy, from renewable energy to waste heat from an engine or a gas burner.
When charging the salt crystals, the Condenser is connected to ambient air or an Air Conditioning system making the liquid in the Condenser to evaporate or boil, which is why the Condenser becomes an Evaporator (”E”). Boiling of the liquid in the Evaporator at room temperature is possible since it is vacuum with a pressure is close to zero. As the liquid evaporates back to the Reactor, the Evaporator gets cold – thus generating cooling.
In the Reactor, the vapor condensates and reacts with the salt, and the chemical energy stored in the salt crystals is released, generating heating. The discharging process ends when all vapor has moved back to the Reactor and the salt is again completely ”wet”. The process can then be restarted, and repeated – over and over again. Thanks to the nano-coating of the salt and matrix, there is no degradation over time: This is the ”X” factor in SaltX.
