VoltStorage GmbH, established in 2016 in Munich, Germany, specializes in developing sustainable energy storage solutions. The company’s primary focus is its Iron Salt Battery technology, designed to make renewable energy accessible 24/7. As a clean technology innovator, VoltStorage serves energy providers, grid operators, and industrial enterprises by providing reliable base-load power through renewable sources like wind and solar. The company’s international team includes experts from nearly 20 countries, working together to advance sustainable energy storage solutions.
Battery Technology
VoltStorage’s Iron Salt Battery technology represents a significant advancement in long-duration energy storage (LDES). This system builds upon proven flow battery principles, utilizing abundant materials – iron and salt – as its core components. The technology offers several technical advantages, including more than 10,000 charge cycles without capacity loss, non-flammable components for enhanced safety, and flexible scalability in both performance and capacity.
The company’s battery solutions are specifically engineered for utility-scale applications, offering cost-effective energy storage for extended periods. Unlike conventional lithium-ion batteries, VoltStorage’s technology eliminates the need for rare earth metals and conflict minerals, making it environmentally responsible and sustainable. The system’s ability to store energy for up to 100 hours makes it particularly effective for managing renewable energy intermittency.
The Iron Salt Battery technology is scheduled for utility-scale implementation starting in 2025, marking a significant step in sustainable energy storage solutions. The system’s design prioritizes complete recyclability, contributing to a reduced carbon footprint while maintaining high operational efficiency.
Recent Projects
In early 2024, VoltStorage appointed Volker Schulte as CEO to lead the company’s global expansion phase. Under this new leadership, VoltStorage is preparing for the first pilot installations of its Iron Salt Battery technology, scheduled for early 2027. The company is currently enhancing its battery health management system and implementing automated test systems to improve technology readiness levels.
Investors
VoltStorage has secured significant financial backing, including a €30 million venture debt loan from the European Investment Bank. Notable investors include Cummins Inc., which contributed €24 million in a Series C funding round, along with Korys Investments, EIT InnoEnergy, Bayern Kapital GmbH, SOSV, and Energie 360°. The total funding raised amounts to $65.49 million, supporting the company’s technological development and market expansion.
