The partnership strengthens France's energy security with innovative grid solutions Hanwha Solutions' Q ENERGY Division (Q ENERGY) and GazelEnergie announced the inauguration of their flagship energy storage project on the Emile Huchet site in Saint-Avold, Moselle. The battery project, with 35. France's energy storage market is experiencing explosive growth, driven by the need to integrate intermittent renewables like solar and wind into its low-carbon grid. As of 2025, the France Energy Storage Systems Market is valued at a significant scale, with projections to reach USD 22,251 million. HiHELIOS aims to deliver a TRL 7 modular, scalable, circular-by-design and safe Hybrid Energy Storage System (HESS) that combines High-Power storage capabilities of LFP battery or supercapacitors, with High-Energy storage capabilities of second-life NMC batteries. To achieve this, HiHELIOS will.
