SaltX develops new energy storage technology to reduce energy consumption and energy storage costs by about 33%

Reported from CSPPLAZA: Recently, Sweden SaltX Technology Company (Referred to as SaltX) introduced a new energy storage technology, which mainly uses the salt crystals and its solution to store and release heat under the action of chemical reactions at different temperatures. This new technology can be applied to solar-thermal power generation, solar refrigeration, air conditioning and other fields. SaltX claims that this technology can reduce energy consumption and energy storage costs by about 33%.

 
It is understood that SaltX is headquartered in Stockholm. Established in 2001, this company has been committed to the development of renewable energy. With the rapid development of green energy in Europe, SaltX won the Bullhound Connect Award in November last year. At present, it has established relations of cooperation with GE, Rheem, Alfa Laval and other companies to provide new energy storage solutions.

 
The SaltX energy storage system consists of two parts – the reactor (R) and the condenser (C). The two tanks are placed in a vacuum and the top is connected through a pipe. In the reactor, the salt crystal and the solution containing the embedded matrix are chemically reacted after heating. The other tank does not contain any salt and there is only the matrix used for liquid condensation.

 
The reactor requires heat to be driven and its operating temperature is at least 100 degrees Celsius. The heat source includes the heat collected by the mirror field of the solar-thermal plant, the waste heat of the gas burner, and the waste heat which is generated during the operation of the generator. When the input heat reaches 100 degrees Celsius, the solution in the reactor can be boiled and then, to keep heating, salt crystals will continue to precipitate. Until the heat stored in the crystal reaches saturation, the solution will automatically flow into the condenser. It deserves attention that during the storage process, part of the heating energy is chemically stored in the salt crystals, and part is rejected as condensation heat.

 
When discharging 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.
