Making Thermal Storage Smart:
STAM’s Digital Vision for HYSTORE

Turning research into real-world solutions

How would you describe STAM’s core business?

STAM is an engineering and technology consulting firm that bridges advanced research and real-world applications. We design innovative and sustainable solutions across energy, sustainability, space, and defence, with a strong focus on digital technologies and system integration.

From thermal storage to smart energy assets

What are the key challenges addressed by HYSTORE, from your perspective and from STAM’s point of view?

One of the main challenges is elevating thermal energy storage to the level of today’s electric batteries—making it smart, grid-interactive, and responsive. This means enabling advanced monitoring, interoperability with the power grid, flexibility services, and resilience. For STAM, the challenge is also digital: translating these advanced concepts into tools that are intuitive for users, scalable across contexts, and future-proof.

Creating value for the market and for STAM

What benefits does HYSTORE bring to the market and to STAM?

HYSTORE paves the way for more efficient and affordable energy storage, higher renewable energy integration, reduced emissions, and lower energy bills. For STAM, the project strengthens our role in ICT and digital energy solutions, allowing us to deliver platforms that connect physical assets—such as thermal energy storage systems and sensors—with advanced digital services for data analysis, optimisation, and orchestration.

STAM’s contribution to HYSTORE

How is STAM contributing to the project?

STAM leads Work Package 4, which focuses on ICT tools and digital infrastructure. Our main contribution is the Data Management Platform, EnPOWER, designed to collect, organise, and manage data from thermal energy storage systems and pilot sites. On top of this, we integrate advanced modules, including federated learning for predictive maintenance, anomaly detection for energy flows, and the Smart Energy Aggregator System (SEAS) for system orchestration. In essence, we provide the digital backbone of HYSTORE.

“HYSTORE shows how thermal storage, powered by advanced digital tools, can become a game-changer for a flexible, sustainable, and smarter energy future.”

Progress and milestones

How is the work progressing, and what has been achieved so far?

We have successfully completed the design phase of the ICT tools (D4.1) and released the Alpha version of the platform (D4.2). The platform is now deployed on cloud infrastructure and includes dashboards for real-time monitoring and data visualisation. Initial integrations with pilot sites in Sweden, Ireland, Spain, and Austria are already underway, validating both the modularity and scalability of the solution.

Impact on HYSTORE and the energy system

What are the benefits of your technology for HYSTORE and the wider market?

Our ICT tools give HYSTORE operational transparency, KPI benchmarking, anomaly detection, and optimisation capabilities. For the wider market, this marks a paradigm shift: thermal energy storage becomes an active, intelligent participant in the energy system, supporting smarter buildings, energy communities, and more resilient grids.

Overcoming complexity

Have you encountered any challenges along the way?

Data harmonisation has been one of the main challenges. Each pilot site uses different sensors, protocols, and system architectures, which required the development of modular and standardised interfaces. Cybersecurity has also been a key concern, ensuring data protection and trust in a distributed, multi-country environment.

Looking ahead

What are the next steps for STAM within HYSTORE?

Our next focus is to strengthen communication with each pilot site and initiate continuous data monitoring through the platform. This will set the stage for advanced analytics, optimisation, and orchestration, further unlocking the potential of smart thermal energy storage.
