Energy storage in
the commercial sector


In light of advancing political and social efforts to combat climate change, the energy supply is currently in a state of comprehensive change. The generation and use of climate-friendly forms of energy is of crucial importance in this context. Companies in the commercial and agricultural sectors also want to contribute to a carbon-neutral energy supply with innovative energy solutions. Ecological energy storage solutions play a special role in enabling 100% renewable energy around the clock.


Self-consumption optimization

By combining a commercial energy storage system with a renewable generation plant, surplus energy can be stored and then retrieved around the clock. This means that during periods of low wind and low sun, users can remain energy self-sufficient, which is an economic advantage in view of rising electricity prices.

Emergency power supply

A reliable power supply is crucial for many companies and their operations. Emergency power storage systems can maintain the necessary power supply even in the case of power failures. This means that essential machines and applications can continue to operate even in the event of a power failure.



A commercial storage system leads to a significant increase in self-consumption and thus to a cheaper energy supply. If more power is generated during the day than is consumed, the energy is available, for example, in the early morning hours to operate the milking robots. In addition, the energy storage system can reliably provide emergency power in the event of a grid failure, thus ensuring security of supply.

Manufacturing industry

To cover energy needs at night, to run production in the early morning hours, or to provide emergency power to continue operations in the event of a power outage – commercial storage offers companies in the manufacturing sector the opportunity to use self-generated energy cost-effectively around the clock, thus increasing their profitability in an ecological way.

Hotel & Gastronomy

In addition to a self-sufficient energy supply and the realization of savings potential, the reduction of the CO2 footprint plays a major role in increasing attractiveness among customers. The use of an efficient storage solution enables the use of sustainable energy even in times of low wind and sunshine, such as early morning or late evening for the operation of the kitchen.


With our international research and development team, we are working on the development of a power storage solution for commercial and agricultural businesses. Based on the ecological vanadium redox flow storage technology, we want to give commercial operators and farmers the opportunity to rely on a particularly durable, safe and lithium-free storage solution.

Technological benefits


Storage systems based on redox flow technology can be charged and discharged as often as required without losing storage capacity. Redox flow storage systems are therefore among the longest-lasting storage solutions on the market.


The vanadium redox flow technology does not require any rare raw materials. The vanadium used in the storage medium is obtained as a by-product of iron production – and thus without overexploitation of nature and the associated impact on our ecosystems.

100% non flammable

Operational safety plays a key role in energy storage. The vanadium redox flow technology offers a decisive advantage in this respect: The vanadium-based electrolyte consists exclusively of non-combustible components, and is mostly pure water.

CO2 saving

With redox flow technology, we are relying on a proven CO2-saving battery technology. Thanks to the ecological redox flow storage technology, energy from renewable sources such as solar and wind power can be used around the clock in a sustainable manner, and contribute to combating climate change.

Vanadium redox flow technology

The vanadium redox flow technology was developed by the US space agency NASA in the 1970s. With its international team of experts, VoltStorage has taken this resource-saving storage technology to a new level in recent years.
