Italian company Green Energy Storage (GES) and RINA have signed a framework agreement for the development of a hydrogen battery designed by GES.
The first prototype is set to be unveiled in December 2025.
The agreement will support GES in moving from a laboratory-scale prototype to a market-ready product, with RINA actively involved in several stages including technology validation.
RINA will ensure the solution meets standards of reliability and performance. The certification organisation will also be involved in the engineering optimisation of the system to make it efficient, scalable, and compliant with applicable regulations.
In addition, RINA will assist GES in its markeingt strategy, facilitating the commercialisation of the technology in the energy sector.
This partnership is a key milestone in accelerating the development of our technology.

The battery itself will be based on a hybrid hydrogen/liquid technology using a manganese-based liquid electrolyte.
The cell will integrate hydrogen production and reabsorption in a closed cycle, eliminating the need for external tanks.
Key technical features of the battery will include:
The use of green chemistry using manganese which is an abundant active material, non-toxic and recyclable.
The battery will also be modular and scalable up to the megawatt scale, with independent energy and power components.
Integration with hybrid systems
The lifespan of the battery is estimated to be 12,000 cycles.
The system also incorporates advanced hardware and software components with integrated AI-enabled sensors, machine learning algorithms, and an advanced Battery Management System (BMS) for maximum operational safety, predictive diagnostics, and integration with hybrid systems.
“This partnership is a key milestone in accelerating the development of our technology,” said Matteo Mazzotta, chief executive officer of GES.
“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.”
Innovative and promising technology
Michele Budetta, chief executive officer of RINA Consulting, added: “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.”
The project is part of the IPCEI (Important Projects of Common European Interest) funded by the European Union under NextGenerationEU.
GES received €61.5 million in funding, covering around 98.5% of the total costs of the project.
