The Grenoble SOEL facility's Digital Twin, developed and tuned to be the precise image of the real system, allows to simulate any required scenario and provides a full time test availability. It logs and send back all the sensors information, from the cells voltage to the thermal gradient acoss the stacks. Start‑ups consume years of time‑series data via Meluxina to predict degradation before it shows up in the lab, then push new set‑points back to the plant Digital Twin the same afternoon, watching efficiency tick upward in real time.
The facility network assembled under EnergyGuard spans Portugal, Spain, France, Italy and Latvia. Each site contributes a unique capability—from grid‑scale digital twins and hydrogen production lines to community microgrids and Soviet‑era apartment blocks—so innovators can address challenges at every step, from generation and storage to consumption and market trading. A curated catalogue of digital twins, datasets, models and inference APIs makes these assets accessible through a unified cloud portal.
Complementing the physical laboratories is the Meluxina supercomputer in Luxembourg. Running entirely on renewable energy, Meluxina lets developers scale simulations across tens of thousands of CPU and GPU cores while keeping their carbon footprint transparent. Containerised workspaces loaded with open‑source libraries mean even small teams can harness petascale muscle without deep HPC expertise. Results stream back to the TEF portal in minutes, allowing rapid iteration that traditional lab schedules simply cannot match.
For innovators, the benefits are clear: dramatically shorter development cycles, lower capital expenditure and a structured path to compliance with the forthcoming EU AI Act. The TEF's Acceptance Environment measures algorithms against a comprehensive risk database, covering cybersecurity threats, data bias, functional safety and more. Passing solutions receive a digital badge that signals trustworthiness to investors, customers and regulators alike.
Looking ahead, CEA‑Liten will leverage its role within EnergyGuard to seed pilot projects, share open datasets and mentor early‑stage companies. By weaving together cutting‑edge infrastructure, transparent governance and a sustainable business model, EnergyGuard aims to make Europe the go‑to market for responsible, high‑impact energy AI.
