VoltStorage Iron Salt Battery

In order to balance the fluctuations of renewable energy sources and to enable the decarbonisation of the energy sector, energy companies need intelligent and economic solutions to reliably integrate renewable energies into the power grid and to drive the widespread use of renewable energies.

Our Iron Salt Battery has been specially developed for application as Long Duration Energy Storage and are suitable for stationary applications with a need for constant power throughout the year.

Base load from renewables? Works!

Renewable energies rethought

The Iron Salt Battery from VoltStorage is a particularly cost-effective, sustainable and universally applicable storage solution for energy utilities to bridge supply gaps during periods of low wind and low sun, ensuring base load electricity.

Green energy becomes base-load capable

Designed for use as a long duration energy storage system, the Iron Salt Battery is suitable for stationary applications with a need for constant power throughout the year. The storage system has a modular design so that the capacity and performance can be flexibly expanded as required. Compared to other technologies in the Long Duration Energy Storage segment, the storage solution also impresses in terms of efficiency with an efficiency of over 70 %. With over 10,000 charging cycles and a service life of more than 20 years, the Iron Salt Battery from VoltStorage also offers a high degree of durability and cost-effectiveness.

Cost-effective

In a Long Duration Energy Storage optimised configuration, the Iron Salt Battery leads to a significant reduction in cost per kWh.

leaf

Eco-friendly

The Iron Salt Battery relies on an iron-based storage medium - and thus on one of the world's most abundant raw materials.

Multifunctional

The system can be installed in a space-saving and decentralised manner, is particularly temperature-resistant and can therefore be used worldwide.

Provision of base load

How wind and solar farms in combination with the Iron Salt Battery from VoltStorage can secure the provision of the base load, we show you with a concrete example in our white paper. Learn more about the economic viabilty as well as the relevance of Long Duration Energy Storage as a key technology for reducing greenhouse gas emissions and paving the way for a net-zero energy system.

Therefore so low cost

In storage systems based on redox flow technology, power can be decoupled from capacity and scaled independently according to demand. In a configuration optimised for long duration storage, this leads to a significant reduction in costs per kWh compared to other storage systems. The cost advantages of this ecological storage technology increase significantly in correlation with the storage duration, which makes this storage technology particularly interesting for use as long duration energy storage from an economic perspective.

Therefore so eco-friendly

With the iron-salt battery technology, we rely on an iron-based storage medium - and thus on one of the most abundant raw materials in the world. The use of ecological materials allows the storage technology to be scaled according to the given needs and thus enables economies of scale to be gained. In addition, thanks to the CO₂-saving technology, electricity from renewable energies can be stored in a sustainable way, thus making a double contribution to combating climate change.

Therefore so versatile

Compared to, for example, storage systems based on hydrogen or pumped-storage power plants, the use of the Iron Salt Battery from VoltStorage does not require massive expenditure in the provision of suitable infrastructure - the system can be connected to existing infrastructure in a space-saving and decentralised manner. Since the Iron Salt technology is a particularly temperature-resistant storage technology, the system can also be used in climatically challenging regions.
