Storing low price energy for times when demand is high

 

Mornings and evenings mean a higher demand of energy. Integration of renewable energy such as wind and solar makes it harder to match the supply when the demand is high. SaltX Energy Storage solves this problem by shifting produced energy to these peaks.

Fundamental for the global transition to renewable energy

 

Large scale energy storage is required to deal with the inconsistency of renewable energy supply. SaltX´s innovation, built with nano-coated salt technology, is a circular thermal energy storage solution that provides peak shifting to energy grid providers, industrial and commercial customers. With a low cost SaltX Energy Storage is enabling the full transition to renewable energy, globally.

And this is how it works

 

SaltX’s patented Energy Storage is a robust industry system with nano-coated salt crystals inside. To store the energy the salt crystals are heated up with electricity. When discharging the salt, both heat at district heating temperatures as well as steam to industrial processes can be released. Resulting in an energy-efficient and sustainable heating and cooling solution.

The system has four key components – two storage tanks and two reactors. One tank for uncharged salt and one for charged salt, and one reactor for charging the salt and one to discharge it. The reactors can easily be custom fitted so it has the capacity to be charged and uncharged with the megawatts needed. The storage tanks, that doesn’t need to be pressurized, are scalable and simple to install.

Why heat?

 

Energy storage is essential for a successful integration of renewable energy into electricity networks. It’s also important for consumers who need reliable electricity and heat supply at a lower cost.

However, heat energy requirements are often underestimated. So it’s worth pointing out that the need for global thermal energy are larger than transport or electricity; in particular, industries with processing, manufacturing and green house growing of food. The demand for clean carbon free energy is getting increasingly bigger within the industry.

 

Why SaltX?

 

The nano-coated salt has a very high energy density, allowing a compact solution for energy storage. This enables a smooth and simple integration into existing facilities.

SaltX’s pilot project in Berlin

 

In May 2017, SaltX presented a joint pilot project with Vattenfall. Following small-scale testing systems in Sweden, a large-scale energy storage facility and system is currently being installed and tested in Berlin’s district heating network.

The storage system is designed to be charged for ten hours and then to be quickly discharged at peak demands during the morning and evening hours.

SaltX Energy Storage solutions


This solution is suitable for large scale implementation. There are two major reasons why: economy of scale and standard components. Storage tanks do not require advanced or expensive materials, and the system is easy to integrate with existing technology.

Two major advantages of storing energy thermo-chemically in salt is high energy density and the possibility to release heat at very high temperatures. The micro-grids can be charged off-peak and then utilize the heat for warming up buildings or using steam in factories.
