ESTEYCO is participating in the ARMIC project (Resilient Modular Storage for Critical Infrastructures), a technological initiative aimed at developing an advanced long-duration thermal energy storage system based on molten silicon. The project seeks to enhance the energy resilience of critical infrastructures through an innovative, safe and high-efficiency solution. 

ARMIC proposes a high energy-density thermal storage technology capable of operating at elevated temperatures, enabling large amounts of energy to be stored over extended periods and released when required. This solution addresses the challenges associated with renewable energy integration and the need to guarantee continuity of supply in strategic environments. 

The project has a planned duration of 36 months and a total budget of €4,760,908, allocated to technological development, experimental validation and industrial scalability of the solution. This project has been funded by CDTI and supported by the Ministry of Science, Innovation and Universities. 

 

A multidisciplinary consortium 

ARMIC is being developed by an industrial consortium composed of: 

• SILBAT S.L. 

• GENERACIONES FOTOVOLTAICA DE LA MANCHA S.L. 

• ESTEYCO S.A. 

• SCHUNK IBÉRICA S.A. 

• RBZ ROBOT DESIGN S.L. 

The integration of industrial capabilities and scientific expertise enables a comprehensive approach to technology development, combining advanced materials, structural engineering, numerical modelling, thermal validation and automation. 

ESTEYCO’s contribution 

Within the project framework, ESTEYCO contributes its expertise in advanced engineering and numerical modelling of complex systems. Its involvement focuses on two main areas: 

• Comprehensive numerical modelling and Digital Twin development, including thermal and structural simulations, extreme-condition performance analysis, and the development of tools for State of Charge (SoC) monitoring and operational optimisation. 

• Design of the modular and inerted containment system, ensuring structural safety, thermal insulation and overall system integrity under high-temperature operating conditions. 

This dual contribution is key to ensuring the technical feasibility, safety and future industrial scalability of the proposed technology. 

Innovation to strengthen energy resilience 

The ARMIC system is based on molten silicon as a thermal storage medium, enabling significantly higher operating temperatures than conventional systems and therefore higher energy densities. Its modular design allows adaptation to different types of critical infrastructures, increasing energy autonomy and reducing vulnerability to supply disruptions. 

Through its participation in ARMIC, ESTEYCO reinforces its positioning in engineering applied to the energy transition and the development of advanced energy storage technologies.
