What the Project Is
Mincatec Energy introduces a revolution in energy storage with its groundbreaking solid hydrogen storage technology. The project is based on a metal hydride reservoir, a system where a metallic powder absorbs and desorbs hydrogen to form crystalline metal hydrides, making hydrogen storage safer and more efficient. The technology is designed to store up to 1 kg of hydrogen, reaching thermodynamic equilibrium at 20°C with a residual pressure of 10 bar (which corresponds to 9 g of gaseous hydrogen). The project stands as a smart solution that integrates advanced thermal management to enable both the absorption (exothermic process releasing heat) and desorption (endothermic process producing cold) of hydrogen, thus ensuring longevity and effective reuse in storage applications.

Innovative Technology and Insights
The core idea behind the solid hydrogen storage solution is as simple as it is ingenious. Metal hydrides, the backbone of the system, make use of metallic bonds to store hydrogen in a solid state. When hydrogen is absorbed, it forms a crystalline solid—and then, when it is desorbed, the process reverses, allowing the metallic powder to be reused nearly infinitely. This reversible process is not just innovative; it is a key step forward in sustainable and infinite hydrogen storage. There is an almost poetic interplay between heat and cold here: absorption releases heat, while desorption produces cooling. This unique duality necessitates thoughtful thermal management, which the project addresses with a modular and compact design.
Diverse Applications and Recent Innovations
The application of this metal hydride hydrogen storage technology spans various fields. For stationary applications, the reservoir is primarily used in a hybrid self-consumption system, ideal for domestic energy management where surplus renewable energy can be stored and later reconverted to electricity. There is also a containerized solution designed specifically for industrial applications to store wind or solar energies—those non‐controllable, intermittent energy forms. In the mobility sector, hydrogen serves as an energy vector, paving the way for cleaner transportation solutions. Recent news from the company highlights participation in major events such as World Smart Energy Week in Tokyo and HYVOLUTION Paris 2025, where the reservoir technology was showcased and industry professionals gathered to discuss the latest in energy transition innovations.
Solid Hydrogen Storage: The Future of Energy
A defining aspect of the project lies in its innovative approach to using stored thermal energy. The compact and modular design of the reservoir allows for cogeneration by utilizing the thermal energy generated during the hydrogen storage process. This means that the energy released during the exothermic absorption is not wasted but can be harnessed for other applications, creating a synergy that contributes to a more efficient energy management process. The technological leap represented by the metal hydride reservoir is a clear indicator that the future of energy might lie in such sustainable, efficient, and adaptable solutions.
Advanced Energy Management and System Integration
The project also emphasizes the importance of an integrated energy management system, which was developed using state-of-the-art control and supervision software. This system offers dual versions to cater to both stationary and mobility applications while optimizing energy inputs from multi-source systems. It features continuous monitoring and a customizable user interface, ensuring that every piece of data from each subsystem is accounted for. In a sort of “safety first” approach, the system also includes a dedicated safety mode and maintenance mode, the latter allowing for remote access for both preventive and corrective actions. These features not only enhance operational efficiency but also instill confidence in the stability and security of the energy storage process.
