Netherlands-based startup Ore Energy has announced the successful completion of a grid-connected technical pilot of its 100-hour Iron-Air Long Duration Energy Storage (LDES) system at EDF Lab les Renardières in Écuelles, France.
The project, which is being implemented under the European Union’s Storage Research Infrastructure Eco-System (StoRIES) programme, is described as the first of its kind in Europe. According to the company, the pilot demonstrates that iron-air LDES can provide multi-day energy storage under real operating conditions.
As part of the EDF pilot implementation, Ore Energy installed its modular iron-air battery system to collect operational data under live grid conditions. Over several months, the system cycled through different load profiles and seasonal conditions, demonstrating its ability to store and discharge energy for up to approximately four days (100 hours). The tests focused on charge-discharge behavior, system responsiveness, and compatibility with standard network management practices.
The technical data generated through the pilot project contributes to StoRIES’ broader mandate to evaluate long-duration storage technologies capable of meeting multi-day renewable energy balancing needs across Europe.
