NextFin News - On February 2, 2026, Green Energy Storage (GES) officially presented its latest technological breakthrough at its headquarters in Rovereto, Italy. The company has developed a high-density hybrid battery system that combines hydrogen with a patented liquid electrolyte based on manganese. This innovation, which has been in development for over a decade, is designed to solve the inherent intermittency of renewable energy sources like solar and wind by providing a scalable, long-duration storage solution. The project has reached a critical milestone with the support of the European Commission and the Italian Ministry of Business and Made in Italy (Mimit), which collectively allocated €61.5 million under the IPCEI Batteries 2 framework. According to Quotidiano, the funding covers approximately 98.5% of the project costs, enabling GES to move from laboratory prototypes to industrial-scale production, with commercial units expected to hit the market by late 2026.
The technical specifications of the GES battery represent a significant leap over existing technologies. According to Pucher, Head of R&D at GES, the manganese-hydrogen system offers an energy density of approximately 100 Wh/l, which is nearly three times that of the best vanadium flow batteries currently available (typically around 35 Wh/l). Furthermore, the system boasts an energy efficiency exceeding 75% and a lifecycle of more than 10,000 cycles, translating to an operational lifespan of over 20 years. Unlike lithium-ion batteries, which are optimized for short-term discharge (4-6 hours), the GES hybrid system is specifically engineered for Long-Duration Energy Storage (LDES), capable of stabilizing grids for days or even weeks. The modular design allows for independent scaling of power and energy components, making it suitable for applications ranging from localized microgrids to megawatt-scale industrial storage.
The strategic importance of this development extends beyond mere technical performance; it addresses the geopolitical vulnerabilities of the European energy transition. Currently, the global battery market is heavily reliant on lithium and cobalt, materials with supply chains largely controlled by non-EU entities. By utilizing manganese—the 12th most abundant element in the Earth's crust—GES is tapping into a raw material with a low-risk, globally distributed supply chain. According to Mazzotta, CEO of GES, less than 10% of the battery's components consist of critical raw materials, a factor that significantly enhances the sustainability and economic sovereignty of the European energy sector. This shift toward "green chemistry" not only lowers production costs but also ensures that the batteries are non-toxic and fully recyclable at the end of their life cycle.
From a financial and industrial perspective, the trajectory of GES serves as a blueprint for European deep-tech commercialization. Since its inception in 2015, the company has utilized a mix of public grants and private capital, including two successful crowdfunding campaigns that raised over €3.3 million from a base of 800 shareholders. The recent partnership with RINA, a multinational engineering consultancy, further validates the technology's readiness for market entry. RINA will oversee the engineering optimization and certification processes, ensuring the system meets international safety and performance standards. As U.S. President Trump continues to emphasize energy independence and industrial competitiveness in the United States, Europe is clearly signaling its intent to maintain a competitive edge in the green technology race through targeted public-private investments like the IPCEI program.
Looking forward, the demand for such storage solutions is projected to accelerate as the integration of Artificial Intelligence (AI) drives up energy consumption in data centers. Pinto, President of GES, noted that the energy requirements for AI will necessitate a doubling of capacity, which can only be sustainably met by coupling renewables with long-duration storage. The company's expansion into Bilbao, Spain, and its plans to open capital to new shareholders by the end of 2026 suggest a rapid scaling phase. As the global energy landscape shifts toward decentralized and resilient grids, the success of the manganese-hydrogen hybrid battery could mark the beginning of a new era where energy storage is defined by material abundance and environmental safety rather than scarcity and geopolitical leverage.
