The partnership will see the battery move from a laboratory-scale prototype to a market-ready product
Green Energy Storage (GES), an Italian innovative company in the green energy storage sector, and RINA, a multinational engineering consultancy, inspection, and certification group, have signed a framework agreement to develop a hydrogen battery designed by GES, with the first prototype scheduled to be revealed in December 2025
Matteo Mazzotta, chief executive officer of GES, said, “This partnership is a key milestone in accelerating the development of our technology. RINA’s contribution, with its international experience and strong engineering and regulatory expertise, not only strengthens the technical soundness of our project but also confirms its value in view of future industrialisation.”
Michele Budetta, chief executive officer of RINA Consulting, said, “We are delighted to support GES in the development of such an innovative and promising technology. Our role will be to guide GES from the laboratory to the market, helping to make this solution technologically robust, regulatory-compliant, and ready to meet the energy challenges of the future.”
GES technology
This new generation of batteries has been developed from hybrid hydrogen/liquid technology using a manganese-based liquid electrolyte. The cell combines hydrogen production and reabsorption in a closed cycle, eliminating the need for external tanks.
The battery's key features include:
- Abundant active materials, non-toxic, recyclable, and a low environmental footprint
- Independent energy and power components, expandable up to the MegaWatt scale
The technology has an estimated lifecycle exceeding 12000 cycles, around 15-20 years of use, to ensure cost optimisation (LCOS) and a reduction in the amount of materials needed in comparison to conventional flow batteries.
In-house production of membranes and catalysts ensures direct control over quality and efficiency, and the integration of AI-enabled sensors, machine learning algorithms, and a Battery Management System (BMS) delivers operational safety, predictive diagnostics, and integration with hybrid systems.
Part of the Important Projects of Common European Interest, IPCEI, the project is funded by the EU under NextGenerationEU. GES has received €61.5 million in funding for this initiative, covering 98.5% of the total costs.
GES-RINA collaboration
The agreement will support GES in transitioning from a laboratory-scale prototype to a market-ready product, with RINA being actively involved in various stages.
RINA is set to be responsible for validating the technology, making sure the solution can match the highest standards of reliability and performance, and for the engineering optimisation of the system to ensure it is efficient, scalable, and compliant with applicable regulations.
